SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
 
This prospectus and any accompanying prospectus supplements contain or incorporate by reference forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. These forward-looking statements represent plans, estimates, objectives, goals, guidelines, expectations, intentions, projections and statements of our beliefs concerning future events, business plans, objectives, expected operating results and the assumptions upon which those statements are based. Forward-looking statements include, without limitation, any statement that may predict, forecast, indicate or imply future results, performance or achievements, and are typically identified with words such as “may,” “could,” “should,” “will,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” or words or phases of similar meaning. We caution that the forward-looking statements are based largely on our expectations and are subject to a number of known and unknown risks and uncertainties that are subject to change based on factors which are, in many instances, beyond our control. Actual results, performance or achievements could differ materially from those contemplated, expressed, or implied by the forward-looking statements.
 
The following factors, among others, could cause our financial performance to differ materially from that expressed in such forward-looking statements:
 
our ability to obtain or maintain necessary regulatory approvals for some of our products;
 
the timely development of competitive new products and services, and the acceptance of these products and services by new and existing customers;
 
the lack of availability of alternate third-party suppliers for certain important product components;
 
the timely development of competitive new products and services, and the acceptance of these products and services by new and existing customers;
 
the willingness of users to substitute competitors’ products and services for our products and services;
 
new developments in health treatments or new non-diagnostic products that reduce or eliminate the demand for our products;
 
changes in consumer spending and savings habits;
 
the strength of the United States economy in general and the strength of the local economies in which the Company conducts operations;
 
geopolitical conditions, including acts or threats of terrorism, actions taken by the United States or other governments in response to acts or threats of terrorism and/or military conflicts, which could impact business and economic conditions in the United States and abroad;
 
the effects of, and changes in, trade, monetary and fiscal policies and laws, including interest rate policies of the Board of Governors of the Federal Reserve System, or the Federal Reserve Board; inflation, interest rate, market and monetary fluctuations;
 
availability of resources for introduction and marketing of our products;
 
technological changes;
 
our ability to attract and retain key employees;
 
continued funding of, and our ability to participate in, large testing programs in the U.S. and worldwide;
 
uncertainty as to our future profitability;
 
the impact of changes in financial services policies, laws and regulations, including laws, regulations and policies concerning taxes, banking, securities and insurance, and the application thereof by regulatory bodies;
 
the effect of acquisitions we may make, including, without limitation, the failure to achieve the expected revenue growth and/or expense savings from such acquisitions;
 
the growth and profitability of non-interest or fee income being less than expected; and
 
unanticipated regulatory or judicial proceedings.
 
Forward-looking statements reflect our current views with respect to future events and are based on assumptions and subject to risks and uncertainties. Given these uncertainties, you should not place undue reliance on these forward-looking statements. We discuss many of these risks in greater detail under the heading “Risk Factors” of this prospectus and in our SEC filings. Also, these forward-looking statements represent our estimates and assumptions only as of the date of the document containing the applicable statement.
 
You should read this prospectus, any accompanying prospectus supplement, the documents we have filed with the SEC that are incorporated by reference and any free writing prospectus that we have authorized for use in connection with this offering completely and with the understanding that our actual future results may be materially different from what we expect.

USE OF PROCEEDS

DESCRIPTION OF COMMON STOCK
 
General
 
This section of the prospectus describes the material terms and provisions of our common stock.  When we offer to sell or otherwise issue shares of our common stock, we will describe the specific terms of the offering and the shares in a supplement to this prospectus.  This summary does not purport to be exhaustive and is qualified in its entirety by reference to our articles of incorporation, as amended, our bylaws, as amended, and the applicable provisions of Nevada law.
 
Our authorized capital stock includes 100,000,000 shares of our common stock, par value $0.01 per share. As of September 13, 2018, there were outstanding:
 
shares of common stock held by approximately 124 stockholders of record;
 
14,173,620 shares of common stock; and
 
stock options exercisable, upon vesting, to acquire 711,968 shares of common stock.
 
The actual number of stockholders is greater than the number of record holders and includes stockholders who are beneficial owners but hold their shares in street name by brokers and other nominees. The number of holders of record also does not include stockholders that may hold shares in trust or by other entities.
 
Our authorized common stock may be increased and altered from time to time in the manner prescribed by Nevada law upon the vote of at least a majority of the shares entitled to vote on the matter.  Our shares of common stock are traded on the Nasdaq Capital Market under the symbol “CEMI.”
 
Holders of our common stock are entitled to one vote for each share held by them of record on our books in all matters to be voted on by the stockholders.  Holders of our common stock are entitled to receive dividends as may be legally declared from time to time by the board of directors, and in the event of our liquidation, dissolution or winding up, to share ratably in all assets remaining after payment of liabilities and amounts owed with respect to any preferred stock or other senior securities.  Declaration of dividends on common stock is subject to the discretion of the board of directors and will depend upon a number of factors, including our future earnings, capital requirements, financial condition, and/or restrictions, if any, imposed by debt instruments or senior securities.  We have not declared dividends on our common stock in the past and we currently anticipate that retained earnings, if any, in the future will be applied to our expansion and development rather than the payment of dividends.
 
The holders of common stock have no preemptive or subscription rights and are not subject to further calls or assessments.  There are no redemption or sinking fund provisions applicable to the common stock.  Under our corporate documents and Nevada law, the election of directors requires a plurality of the votes cast by holders of our outstanding common stock at the annual meeting while other fundamental corporate actions, such as mergers and sales of substantial assets, or amendments of our articles of incorporation require the approval of the holders of a majority of our outstanding common stock.
 
Transactions with Interested Persons
 
Under Nevada law, a transaction with the Company (i) in which a Company director or officer has a direct or indirect interest, or (ii) involving another corporation, firm or association in which one or more of the Company’s directors or officers are directors or officers of the corporation, firm or association or have a financial interest in the corporation firm or association, is not void or voidable solely because of the director’s or officer’s interest or common role in the transaction if any one of the following circumstances exists:
 
the fact of the common directorship, office or financial interest is known to the board of directors or a committee of the board of directors and a majority of disinterested directors on the board of directors (or on the committee) authorized, approved or ratified the transaction;
 
the fact of the common directorship, office or financial interest is known to the stockholders and disinterested stockholders holding a majority of the shares held by disinterested stockholders authorized, approved or ratified the transaction;
 
the fact of the common directorship, office or financial interest is not known to the director or officer at the time the transaction is brought to the board of directors for action; or
 
the transaction was fair to the Company at the time it is authorized or approved.
 
Control Share Acquisition Provisions
 
Nevada law precludes an acquirer of the shares of a Nevada corporation who crosses one of three ownership thresholds (20%, 33 1/3% or 50%) from obtaining voting rights with respect to those shares unless the disinterested holders of a majority of the shares of the Company held by disinterested stockholders vote to accord voting power to those shares. Nevada permits a corporation to opt out of the application of these control share acquisition provisions by so providing in the articles of incorporation or bylaws.  The Company has opted out of the application of these control share acquisition provisions in its bylaws, as amended.
 
Combinations with Interested Stockholders
 
Under Nevada law, except under certain circumstances, a corporation is not permitted to engage in a business combination with any “interested stockholder” for a period of two years following the date such stockholder became an interested stockholder.  An “interested stockholder” is a person or entity who owns 10% or more of the outstanding shares of voting stock.  Nevada permits a corporation to opt out of the application of these business combination provisions by so providing in the articles of incorporation.  The Company did not opt out of the application of these business combination provisions in its articles of incorporation, as amended.
 
Stockholder Rights Agreement

On March 8, 2016, the Company entered into a Rights Agreement (the “Rights Agreement”) between the Company and Action Stock Transfer Corp., as Rights Agent.  Pursuant to the Rights Agreement, the Company declared a dividend distribution of one Preferred Share Purchase Right (a “Right”) for each outstanding share of our common stock, par value $0.01, in the manner described below. The board of directors set the payment date for the distribution of the Rights as March 8, 2016, and the Rights were distributed to our shareholders of record on that date.  The Rights Agreement also provides that Rights are issued with respect to any shares of our common stock that are newly issued after March 8, 2016, such as with respect to the Company’s underwritten public offering in February 2018.  The description and terms of the Rights are set forth in the Rights Agreement.

Rights Initially Not Exercisable.  The Rights are not exercisable until a Distribution Date (as defined in the Rights Agreement).  Until a Right is exercised, the holder thereof, as such, has no rights as a shareholder of the Company, including, without limitation, the right to vote or to receive dividends.

Separation and Distribution of Rights.  The Rights are to be evidenced by the certificates for shares of common stock registered in the names of the holders thereof, and not by separate rights certificates until the earlier to occur of (i) the close of business on the tenth business day following a public announcement that an Acquiring Person (as defined in the Rights Agreement) has acquired a Combined Ownership (as defined in the Rights Agreement) of 20% or more of the outstanding shares of the common stock or (ii) the close of business on the tenth business day (or such later date as may be determined by action of the board of directors prior to such time as any person or group of affiliated or associated persons becomes an Acquiring Person) after the date that a tender or exchange offer or intention to commence a tender or exchange offer by any person is first published, announced, sent or given within the meaning of Rule 14d-4(A) under the Securities Exchange Act of 1934, as amended, the consummation of which would result in any person having Combined Ownership of 20% or more of the outstanding shares of the common stock.

Transfer Agent
 
The transfer agent and registrar for the Company’s common stock is Action Stock Transfer Corp.
 
DESCRIPTION OF PREFERRED STOCK
 
General
 
This section of the prospectus describes the material terms and provisions of our preferred stock.  When we offer to sell or otherwise issue shares of our preferred stock, we will describe the specific terms of the offering and the shares in a supplement to this prospectus.  The prospectus supplement will also indicate whether the terms and provisions described in this prospectus apply to the particular series of preferred stock.  This summary does not purport to be exhaustive and is qualified in its entirety by reference to our articles of incorporation, as amended, our bylaws, as amended, and the applicable provisions of Nevada law.
 
Our authorized capital stock includes 10,000,000 shares of our preferred stock, par value $0.01 per share.  Under our Articles of Incorporation, as amended, we may issue shares of preferred stock in one or more series, as may be determined by our board of directors or a duly authorized committee.  Our board of directors or a committee thereof also may establish, from time to time, the number of shares to be included in each series and may fix the designation, powers, preferences and rights of the shares of each such series and any qualifications, limitations or restrictions thereof, and may increase or decrease the number of shares of any series without any further vote or action by the stockholders.
 
Our board of directors is authorized to determine or fix from time to time by resolution the following terms for each series of preferred stock, which will be described in a prospectus supplement:
 
the distinctive serial designation of such series and the number of shares to constitute such series;
 
the class or voting rights, if any;
 
6

the dividend rate;
 
whether dividends are cumulative and, if so, the date from which dividends cumulate;
 
the payment date for dividends;
 
redemption rights, the applicable redemption prices and such other conditions of redemption;
 
amounts payable to holders on our liquidation, dissolution or winding up;
 
the amount of the sinking fund, if any;
 
whether the shares will be convertible or exchangeable into other equity securities, and, if so, the prices and terms of conversion and such other terms and conditions of such conversion or exchange; and
 
any other voting powers, designations, preferences, limitations, restrictions, and relative rights.
 
The preferred stock will be, when issued, fully paid and non-assessable.  Holders of preferred stock will not have any preemptive or subscription rights to acquire more stock of the Company.
 
The transfer agent, registrar, dividend disbursing agent and redemption agent for shares of each series of preferred stock will be named in the prospectus supplement relating to such series.
 
The rights of holders of the preferred stock offered may be adversely affected by the rights of holders of any shares of preferred stock that may be issued in the future.  The board of directors may cause shares of preferred stock to be issued in public or private transactions for any proper corporate purpose.  Examples of proper corporate purposes include issuances to obtain additional financing in connection with acquisitions or otherwise, and issuances to our officers, directors and employees pursuant to benefit plans or otherwise.
 
Rank
 
Unless otherwise specified in the prospectus supplement relating to the shares of any series of preferred stock, such shares will rank on an equal basis with each other series of preferred stock and prior to the common stock as to dividends and distributions of assets.
 
Dividends
 
The holders of each series of preferred stock will be entitled to receive cash dividends if declared by our board of directors out of funds we can legally use for payment. The prospectus supplement will indicate the dividend rates and the dates on which we will pay dividends as to each series of preferred stock The rates may be fixed or variable or both.  If the dividend rate is variable, the formula used to determine the dividend rate will be described in the prospectus supplement.  We will pay dividends to the holders of record of each series of preferred stock as they appear on the record dates fixed by our board of directors.
 
Conversion or Exchange
 
The applicable prospectus supplement for any series of preferred stock will state the terms, if any, on which shares of that series are convertible or exchangeable into shares of our common stock or another series of our preferred stock.  The terms of any such conversion or exchange and any such preferred stock will be described in the prospectus supplement relating to such series of preferred stock.
 
Redemption
 
If so specified in the applicable prospectus supplement, a series of preferred stock may be redeemable at any time, in whole or in part, at our option or at the option of the holder thereof.  It also may be mandatorily redeemed subject to a mandatory redemption.
 
7

Unless we default in the payment of the redemption price, dividends will cease to accrue after the redemption date on shares of preferred stock called for redemption and all rights of holders of such shares will terminate, except for the right to receive the redemption price.
 
Liquidation Preference
 
Upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, holders of each series of preferred stock will be entitled to receive distributions upon liquidation in the amount set forth in the prospectus supplement relating to such series of preferred stock.  Such distributions will be made before any distribution is made on common stock or on any other securities ranking junior to the preferred stock with respect to liquidation.
 
If the liquidation amounts payable relating to the preferred stock of any series and any other securities ranking on a parity regarding liquidation rights are not paid in full, the holders of the preferred stock of such series and such other securities will share in any such distribution of our available assets on a ratable basis in proportion to the full liquidation preferences.  Holders of such series of preferred stock will not be entitled to any other amounts from us after they have received their full liquidation preference.
 
Voting Rights
 
The holders of shares of preferred stock will have no voting rights, except as otherwise stated in the prospectus supplement and the certificate of designation establishing such series, or as required by applicable law.
 
DESCRIPTION OF WARRANTS
 
In this section, we describe the general terms and provisions of the warrants for the purchase of preferred stock or common stock that we may issue.  Warrants issued pursuant to this prospectus may be issued independently or together with any preferred stock or common stock.  Warrants sold with other securities may be attached to or separate from the other securities.  Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent who will be specified in the warrant agreement and in the prospectus supplement.  The warrant agent will act solely as our agent in connection with the warrants of that series and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.
 
This summary of some of the terms and other provisions of the warrants that may be issued is not complete and is qualified in its entirety by reference to the applicable warrant agreement and related warrant certificate and the prospectus supplement, which both will be filed with the SEC.  You should refer to this prospectus, the prospectus supplement, the free writing prospectus, and the warrant agreement, including the forms of securities warrant certificate representing the securities warrants, relating to the specific warrants that we may offer for the complete terms of the warrant agreement and the warrants.  For more information on how you can obtain copies of the applicable warrant agreement, if we offer warrants, see “Where You Can Find More Information.”  We urge you to read the applicable warrant agreement and the applicable prospectus supplement and any other offering material in their entirety.

the terms of the securities purchasable upon exercise of such warrants and the procedures and conditions relating to the exercise of such warrants;
 
any provisions for adjustment of the number or amount of securities receivable upon exercise of the warrants or the exercise price of the warrants;

if applicable, the minimum or maximum amount of the warrants that may be exercised at any one time;
 
information with respect to book-entry procedures, if any; and
 
any other material terms of the warrants.
 
The prospectus supplement relating to any warrants to purchase equity securities may also include, if applicable, a discussion of certain U.S. federal income tax and ERISA considerations.
 
Each warrant will entitle its holder to purchase the number of shares of preferred stock or common stock at the exercise price set forth in, or calculable as set forth in, the applicable prospectus supplement and warrant agreement.
 
After the close of business on the expiration date, unexercised warrants will become void.  We will specify the place or places where, and the manner in which, warrants may be exercised in the applicable prospectus supplement.
 
Upon receipt of payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement or free writing prospectus, we will, as soon as practicable, forward the purchased securities.  If less than all of the warrants represented by the warrant certificate are exercised, a new warrant certificate will be issued for the remaining warrants.
 
Prior to the exercise of any warrants to purchase preferred stock or common stock, holders of the warrants will not have any of the rights of holders of the preferred stock or common stock purchasable upon exercise, including, the right to vote or to receive any payments of dividends on the preferred stock or common stock purchasable upon exercise.
 
DESCRIPTION OF UNITS
 
In this section, we describe the general terms and provisions of the units that we may offer.  We may issue units consisting of one or more of the securities described in this prospectus in any combination.  Each unit will be issued so that the holder of the unit also is the holder of each security included in the unit.  Thus, the holder of a unit will have the rights and obligations of a holder of each included security.  The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately at any time or at any time before a specified date.
 
The applicable prospectus supplement will specify the following terms of any units in respect of which this prospectus is being delivered:
 
9

the terms of the units and of any of the common stock, preferred stock and warrants comprising the units, including whether and under what circumstances the units may be traded separately;
 
a description of the terms of any unit agreement governing the units;
 
a description of the provisions for the payment, settlement, transfer or exchange of the units or the securities comprising those units; and
 
whether the units will be issued fully registered or in global form.
 
The description in the applicable prospectus supplement and other offering material of any units we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable unit agreement, which will be filed with the SEC if we offer units.  For more information on how you can obtain copies of the applicable unit agreement if we offer units, see “Where You Can Find More Information.”  We urge you to read the applicable unit agreement and the applicable prospectus supplement and any other offering material in their entirety.
 
PLAN OF DISTRIBUTION
 
We may sell the securities described in this prospectus to or through one or more agents, underwriters, dealers or directly to purchasers on a continuous or delayed basis.
 
The distribution of the securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed from time to time, at market prices prevailing at the times of sale, at prices related to such prevailing market prices or at negotiated prices.
 
Each time that we use this prospectus to sell our securities, we will also provide a prospectus supplement.  For each series of securities, the applicable prospectus supplement will set forth the terms of the offering including:
 
the public offering price;
 
the name or names of any underwriters, dealers or agents;
 
the purchase price of the securities;
 
the proceeds from the sale of the securities to us;
 
any underwriting discounts, agency fees, or other compensation payable to underwriters or agents;
 
any discounts or concessions allowed or reallowed or repaid to dealers; and
 
the securities exchanges on which the securities will be listed, if any.
 
If we use underwriters in the sale of securities, the securities will be acquired by the underwriters for their own account.  The underwriters may then resell the securities in one or more transactions at a fixed public offering price or at varying prices determined at the time of sale or thereafter.  The securities may be either offered to the public through underwriting syndicates represented by managing underwriters, or directly by underwriters.  The obligations of the underwriters to purchase the securities will be subject to certain conditions.  The underwriters will be obligated to purchase all the securities offered if they purchase any securities.  The public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time. If an underwriter is utilized in the sale of the securities being offered by this prospectus, an underwriting agreement will be executed with the underwriter at the time of sale and the name of any underwriter will be provided in the prospectus supplement used by the underwriter to make resales of the securities to the public.
 
10

If we use dealers in the sale of securities, we will sell securities to such dealers as principals.  The dealers may then resell the securities to the public at varying prices to be determined by such dealers at the time of resale.  We may solicit offers to purchase the securities directly, and we may sell the securities directly to institutional or other investors, who may be deemed underwriters within the meaning of the Securities Act with respect to any resales of those securities.  The terms of these sales will be described in the applicable prospectus supplement.  If we use agents in the sale of securities, unless otherwise indicated in the prospectus supplement, they will use their reasonable best efforts to solicit purchases for the period of their appointment.  Unless otherwise indicated in a prospectus supplement, if we sell directly, no underwriters, dealers or agents would be involved.  We will not make an offer of securities in any jurisdiction that does not permit such an offer.
 
We may grant underwriters who participate in the distribution of securities an option to purchase additional securities to cover overallotments, if any, in connection with the distribution.  Any underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with SEC orders, rules and regulations and applicable law.  To the extent permitted by applicable law and SEC orders, rules and regulations, an overallotment involves sales in excess of the offering size, which create a short position.  Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.  To the extent permitted by applicable law and SEC orders, rules and regulations, short covering transactions involve purchases of the common stock in the open market after the distribution is completed to cover short positions.  Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the common stock originally sold by the dealer is purchased in a covering transaction to cover short positions.  Those activities may cause the price of the common stock to be higher than it would otherwise be.  If commenced, the underwriters may discontinue any of the activities at any time.
 
Any underwriters who are qualified market makers on the Nasdaq Capital Market may engage in passive market making transactions in the common stock on the Nasdaq Capital Market in accordance with Rule 103 of Regulation M, during the business day prior to the pricing of the offering, before the commencement of offers or sales of the common stock.  Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers.  In general a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain purchase limits are exceeded.
 
Underwriters, dealers and agents that participate in any distribution of securities may be deemed to be underwriters as defined in the Securities Act.  Any discounts, commissions or profit they receive when they resell the securities may be treated as underwriting discounts and commissions under the Securities Act of 1933, as amended.  Only underwriters named in the prospectus supplement are underwriters of the securities offered in the prospectus supplement.  We may have agreements with underwriters, dealers and agents to indemnify them against certain civil liabilities, including certain liabilities under the Securities Act, or to contribute with respect to payments that they may be required to make.
 
We may authorize underwriters, dealers or agents to solicit offers from certain institutions whereby the institution contractually agrees to purchase the securities from us on a future date at a specific price.  This type of contract may be made only with institutions that we specifically approve. Such institutions could include banks, insurance companies, pension funds, investment companies and educational and charitable institutions.  The underwriters, dealers or agents will not be responsible for the validity or performance of these contracts.
 
Each series of securities will be a new issue of securities and will have no established trading market, other than our common stock, which is listed on the Nasdaq Capital Market.  Unless otherwise specified in the applicable prospectus supplement, the securities will not be listed on any exchange.  It has not presently been established whether the underwriters, if any, of the securities will make a market in the securities.  If the underwriters make a market in the securities, such market making may be discontinued at any time without notice.  No assurance can be given as to the liquidity of the trading market for the securities.
 
Agents, dealers and underwriters may be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which the agents, dealers or underwriters may be required to make in respect thereof.  Agents, dealers or underwriters may be customers of, engage in transactions with, or perform services for us and our subsidiaries in the ordinary course of business.

Item 15.
Indemnification of Directors and Officers.
 
The Registrant’s bylaws provide that it will indemnify any of its directors, officers, other employees or agents against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such director, officer, other employee or agent in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, relating to service for or at the request of the Registrant.  The Registrant will not indemnify a director, officer, other employee or agent if in relation to matters such director, officer, other employee or agent is adjudged in the action, suit or proceeding to not have acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the Registrant in the performance of the individual’s duties.

The Registrant’s bylaws also provide that it will advance expenses (including attorneys’ fees) incurred by an officer or director defending an action, suit or proceeding, upon receipt of an undertaking by or on behalf of such officer or director to repay such amount if that officer of director is determined to not be entitled to indemnification. Such expenses incurred by other employees and agents may be paid in advance by the Registrant upon certain terms and conditions deemed appropriate by the board of directors of Chembio.

The Registrant’s articles of incorporation provide that no director will be personally liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director, except that the director’s liability will not be eliminated or limited: (A) for acts or omissions involving intentional misconduct, fraud or a knowing violation of the law; or (B) for the payment of any distribution in violation of Nevada law.

Nevada law permits a Nevada corporation, such as the Registrant, to indemnify its directors and officers in certain circumstances.  Specifically, Section 78.7502 of the Nevada Revised Statutes provides as follows:

“(1) A corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, except an action by or in the right of the corporation, by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with the action, suit or proceeding if the person: (a) is not liable pursuant to Nevada Revised Statutes 78.138 or (b) acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful.  The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, does not, of itself, create a presumption that the person is liable pursuant to Nevada Revised Statutes 78.138 or did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation, or that, with respect to any criminal action or proceeding, he or she had reasonable cause to believe that the conduct was unlawful.
 
15

(2)   A corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses, including amounts paid in settlement and attorneys’ fees actually and reasonably incurred by the person in connection with the defense or settlement of the action or suit if the person: (a) is not liable pursuant to Nevada Revised Statutes 78.138 or (b) acted in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation.  Indemnification may not be made for any claim, issue or matter as to which such a person has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court in which the action or suit was brought or other court of competent jurisdiction determines upon application that in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper.

(3)   To the extent that a director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (1) and (2), or in defense of any claim, issue or matter therein, the corporation shall indemnify him or her against expenses, including attorneys’ fees, actually and reasonably incurred by him or her in connection with the defense.”

Item 17.
Undertakings
 
(a)   The undersigned Registrant hereby undertakes:
 
16

(1)   To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(A)   to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended;

(B)    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 set forth in the registration statement.  Notwithstanding the foregoing, any increase or decrease in volume 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 Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(C)    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;

provided, however, that paragraphs (i), (ii) and (iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended, that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)    That, for the purpose of determining any liability under the Securities Act of 1933, as amended, 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.

(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, as amended, to any purchaser:

(A)   Each prospectus filed by the Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B)    Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of the registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933, as amended, shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus.  As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 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 effective date, 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 effective date.

(5)   That, for the purpose of determining liability of the Registrant under the Securities Act of 1933, as amended, to any purchaser in the initial distribution of the securities, the undersigned Registrant undertakes that in a primary offering of securities of the undersigned Registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
 
17

(A)   Any preliminary prospectus or prospectus of the undersigned Registrant relating to the offering required to be filed pursuant to Rule 424;

(B)    Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned Registrant or used or referred to by the undersigned Registrant;

(C)    The portion of any other free writing prospectus relating to the offering containing material information about the undersigned Registrant or its securities provided by or on behalf of the undersigned Registrant; and

(D)   Any other communication that is an offer in the offering made by the undersigned Registrant to the purchaser.

(b)   The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, as amended, each filing of the Registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934, as amended), that is incorporated by reference in the registration statement 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.

(c)   Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933, as amended, 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 of 1933, as amended, and will be governed by the final adjudication of such issue.
