Company does not have any material subsidiaries. The Company is qualified to do business as a foreign corporation and is in good standing in every jurisdiction in which the nature of the business conducted or property owned by it makes such

any effect on the business, operations, properties or financial condition of the Company that is material and adverse to the Company, taken as a whole, and any condition, circumstance or situation that would prohibit the Company from entering into

authority to enter into and perform the Transaction Documents and to issue the Shares in accordance with the terms hereof. The execution, delivery and performance of the Transaction Documents by the Company and the consummation by it of the

Company, the Transaction Documents shall constitute a valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, reorganization,
moratorium, liquidation, conservatorship, receivership or similar laws relating to, or affecting generally the enforcement of, creditor’s rights and remedies or by other equitable principles of general application. 

(c) Issuance of Shares. The Shares to be issued and sold hereunder have been duly authorized by all necessary corporate action and, when
issued in accordance with the terms hereof, will be validly issued, fully paid and nonassessable. In addition, the Shares will be free and clear of all liens, claims, charges, security interests or agreements, pledges, assignments, covenants,
restrictions or other encumbrances created by, or imposed by, the Company (collectively, “Encumbrances”) and rights of refusal of any kind imposed by the Company (other than restrictions on transfer under applicable securities laws)
and the holder of such Shares shall be entitled to all rights accorded to a holder of Common Stock. The Company has not issued any shares of Common Stock, shares of Series A preferred stock, options or warrants since its most recent report on Form 10-Q. 
 (d) No Conflicts; Governmental Approvals. The execution, delivery and performance of the
Transaction Documents by the Company and the consummation by the Company of the transactions contemplated hereby do not and will not (i) violate any provision of the Company’s Articles of Incorporation or Bylaws, each as amended to date,

deed of trust, indenture, note, bond, license, lease agreement, instrument or obligation to which the Company is a party or by which the Company’s properties or assets are bound, or (iii) result in a violation of any federal, state, local
or foreign statute, rule, regulation, order, judgment or decree (including federal and state securities laws and regulations) applicable to the Company or by which any property or asset of the Company is bound or affected, except for such conflicts,
defaults, terminations, amendments, acceleration, cancellations and violations as would not, individually or in the aggregate, have a Material Adverse Effect. The Company is not required under federal, state, foreign or local law, rule or


  
 7 







 
regulation to obtain any consent, authorization or order of, or make any filing or registration with, any court or governmental agency in order for it to execute, deliver or perform any of its

trigger any right, obligation or event as a result of the issuance of such Shares and Intrexon’s ownership of such Shares and there are no similar anti-takeover provisions under the Company’s charter documents. 

(q) Listing and Maintenance Requirements. The Company is in compliance with the requirements of the Trading Market for continued trading
of the Common Stock pursuant thereto. The issuance and sale of the Shares hereunder does not contravene the rules and regulations of the Trading Market. 

(r) Private Placement. Neither the Company nor its Affiliates, nor any Person acting on its or their behalf, (i) has engaged in any
form of general solicitation or general advertising (within the meaning of Regulation D under the Securities Act) in connection with the offer or sale of the Shares hereunder, (ii) has, directly or indirectly, made any offers or sales of any
security or solicited any offers to buy any security, under any circumstances that would require registration of the sale and issuance by the Company of the Shares under the Securities Act or (iii) has issued any shares of Common Stock or
shares of any series of preferred stock or other securities or instruments convertible into, exchangeable for or otherwise entitling the holder thereof to acquire shares of Common Stock which would be integrated with the sale of the Shares to
Intrexon for purposes of the Securities Act or of any applicable stockholder approval provisions, including, without limitation, under the rules and regulations of any exchange or automated quotation system on which any of the securities of the
Company are listed or designated, nor will the Company or any of its subsidiaries or affiliates take any action or steps that would require registration of any of the Shares under the Securities Act or cause the offering of the shares to be
integrated with other offerings. Assuming the accuracy of the representations and warranties of Intrexon, the offer and issuance of the Shares by the Company to Intrexon pursuant to this Agreement will be exempt from the registration requirements of
the Securities Act.

 (s) No Manipulation of Stock. The Company has not taken, and has no plans to take,
in violation of applicable law, any action outside the ordinary course of business designed to, or that might reasonably be expected to, cause or result in unlawful manipulation of the price of the Common Stock. 

(t) Brokers. Other than Dawson James, neither the Company nor any of the officers, directors or employees of the Company has employed
any broker or finder in connection with the transaction contemplated by this Agreement. The Company shall indemnify Intrexon from and against any broker’s, finder’s or agent’s fees for which the Company is responsible. 

(u) Solvency. Based on the financial condition of the Company as of the Closing Dates, after giving effect to the receipt by the Company
of the proceeds from the sale of the Shares hereunder, (i) the fair saleable value of the Company’s assets exceeds the amount that will be required to be paid on or in respect of the Company’s existing debts and other liabilities
(including known contingent liabilities) as they mature; (ii) the Company’s assets do not constitute unreasonably small capital to carry on its business as now conducted and as proposed to be conducted including its capital needs taking
into account the particular capital requirements of the business conducted by the Company, and projected capital requirements and capital availability thereof; and (iii) the current cash flow of the Company, together with the proceeds the
Company would receive, were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its liabilities when such amounts are required to be paid. The
Company does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt). Assuming the Closing occurs, the Company has no knowledge of
any facts or circumstances which lead it to believe that it will file for reorganization or liquidation under the bankruptcy or reorganization laws of any jurisdiction within one year from the Closing Date. 

(v) Foreign Corrupt Practices. Neither the Company, nor to the knowledge of the Company, any agent or other person acting on behalf of
the Company, has (i) directly or indirectly, used any funds for unlawful contributions, gifts, entertainment or other unlawful expenses related to foreign or domestic political activity, (ii) made any unlawful payment to foreign or
domestic government officials or employees or to any foreign or domestic political parties or campaigns from corporate funds, (iii) failed to disclose fully any contribution made by the Company (or made by any person acting on its behalf of
which the Company is aware) which is in violation of law, or (iv) violated in any material respect any provision of the Foreign Corrupt Practices Act of 1977, as amended. 

(w) Voting Agreement. The signatories to the Voting Agreement have voting control with respect to the Company as of the date hereof,
amounting to, in the aggregate, a majority of the issued and outstanding Common Stock. 
 3.2 Representations and Warranties of
Intrexon. Intrexon hereby represents and warrants to the Company as follows (as of the Closing Date, unless otherwise noted below): 

  
 13 







 (a) Authority. The execution, delivery and performance by Intrexon of the transactions
contemplated by this Agreement have been duly authorized by all necessary corporate or similar action on the part of Intrexon. Each Transaction Document to which it is a party has been duly executed by Intrexon, and when delivered by Intrexon in
accordance with the terms hereof, will constitute the valid and legally binding obligation of Intrexon, enforceable against it in accordance with its terms, except (i) as limited by general equitable principles and applicable bankruptcy,
insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other
equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable law. 
 (b) Own
Account. Intrexon understands that the Shares are “restricted securities” and have not been registered under the Securities Act or any applicable state securities law and is acquiring the Shares as principal for its own account and not
with a view to or for distributing or reselling such Shares or any part thereof in violation of the Securities Act or any applicable state securities law, has no present intention of distributing any of such Shares in violation of the Securities Act
or any applicable state securities law and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of such Shares (this representation and warranty not limiting Intrexon’s right
to sell the Shares pursuant to the Registration Statement or otherwise in compliance with applicable federal and state securities laws) in violation of the Securities Act or any applicable state securities law. Intrexon is acquiring the Shares
hereunder in the ordinary course of its business. Intrexon understands that it may not be able to sell any of the Shares without prior registration under the Securities Act or the existence of an exemption from such registration requirement. 

(c) No Conflicts. The execution, delivery and performance by Intrexon of this Agreement and the consummation by Intrexon of the
transactions contemplated hereby and thereby will not (i) result in a violation of the organizational documents of Intrexon, (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a
default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which Intrexon is a party, or (iii) result in a violation of any law, rule, regulation, order,
judgment or decree (including federal and state securities laws) applicable to Intrexon, except in the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which would not, individually or in the aggregate,
reasonably be expected to have a material adverse effect on the ability of Intrexon to perform its obligations hereunder. 
 (d) Purchaser
Status. At the time Intrexon was offered the Shares, it was, and at the date hereof is, an “accredited investor” as defined in Rule 501 under the Securities Act. Investor is not a registered broker dealer registered under
Section 15(a) of the Exchange Act, or a member of the Financial Industry Regulatory Authority Inc. (“FINRA”), or an entity engaged in the business of being a broker-dealer. 

(e) Experience of Intrexon. Intrexon, either alone or together with its representatives, has such knowledge, sophistication and
experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Shares, and has so evaluated the merits and risks of such investment. Intrexon is able to bear the economic risk
of an investment in the Shares and, at the present time, is able to afford a complete loss of such investment. Intrexon acknowledges that it has not received any legal or tax advice from the Company or any of its representatives with respect the
transactions contemplated hereby. 
  

  
 14 







 (f) No Trading Market for Shares. Intrexon understands and acknowledges that there is no
market for the Shares and that none is likely to develop and that the Shares will not be listed on any Trading Market. 
 (g) General
Solicitation. Intrexon is not purchasing the Shares as a result of any advertisement, article, notice or other communication regarding the Shares published in any newspaper, magazine or similar media or broadcast over television or radio or
presented at any seminar or any other general solicitation or general advertisement. 
 (h) Access to Information. Intrexon
acknowledges that it has had the opportunity to review any Company information and business updates requested by Intrexon and has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers
from, representatives of the Company concerning the terms and conditions of the offering of the Shares and the merits and risks of investing in the Shares and; (ii) access to information about the Company and its financial condition, results of
operations, business, properties, management and prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort
or expense that is necessary to make an informed investment decision with respect to the investment. Intrexon has sought such accounting, legal and tax advice as it has considered necessary to make an informed decision with respect to its
acquisition of the Shares. Intrexon also acknowledges that it has had the opportunity to review the Series B Preferred Financing terms and transaction documents. 

(i) Certain Trading Activities. As of the date hereof, other than with respect to the transactions contemplated herein, since the time
that Intrexon was first contacted by the Company or any other Person regarding the transactions contemplated hereby, neither Intrexon nor any Affiliate of Intrexon which (x) had knowledge of the transactions contemplated hereby, (y) has or
shares discretion relating to Intrexon’s investments or trading or information concerning Intrexon’s investments, including in respect of the Shares, and (z) is subject to Intrexon’s review or input concerning such
Affiliate’s investments or trading (collectively, “Trading Affiliates”) has directly or indirectly, nor has any Person acting on behalf of or pursuant to any understanding with Intrexon or Trading Affiliate, effected or agreed
to effect any purchases or sales of the securities of the Company (including, without limitation, any Short Sales involving the Company’s securities). Notwithstanding the foregoing, in the case of a Intrexon and/or Trading Affiliate that is,
individually or collectively, a multi-managed investment bank or vehicle whereby separate portfolio managers manage separate portions of Intrexon or Trading Affiliate’s assets and the portfolio managers have no direct knowledge of the
investment decisions made by the portfolio managers managing other portions of Intrexon’s or Trading Affiliate’s assets, the representation set forth above shall apply only with respect to the portion of assets managed by the portfolio
manager that have knowledge about the financing transaction contemplated by this Agreement. Other than to other Persons party to this Agreement, their affiliates and each of their respective professional advisors, Intrexon maintained the
confidentiality of all non-public information disclosed to it in connection with the transactions contemplated hereby (including the existence and terms of such transactions) at all times prior to the issuance
of the Press Release (as defined below). 

  
 15 







 (j) Brokers and Finders. No Person will have, as a result of the transactions contemplated
by this Agreement, any valid right, interest or claim against or upon the Company or Intrexon for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding entered into by or on behalf of Intrexon. 

(k) Independent Investment Decision. Intrexon has independently evaluated the merits of its decision to purchase Shares pursuant to the
Transaction Documents, and Intrexon confirms that it has not relied on the advice of any other business and/or legal counsel in making such decision. Intrexon understands that nothing in this Agreement or any other materials presented by or on
behalf of the Company to Intrexon in connection with the purchase of the Shares constitutes legal, tax or investment advice. Intrexon has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or
appropriate in connection with its purchase of the Shares. 
 (l) No Governmental Review. Intrexon understands that no United States
federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Shares or the fairness or suitability of the investment in the Shares nor have such authorities passed upon or
endorsed the merits of the offering of the Shares. 
 (m) Residency. Intrexon’s residence (if an individual) or office in which
its investment decision with respect to the Shares was made (if an entity) are located at the address immediately below Intrexon’s name on its signature page hereto. 

(n) Acknowledgment. Intrexon acknowledges and agrees that Intrexon has reviewed and considered prior to entering this Agreement the more
detailed information about the Company and the risk factors that may affect the realization of forward-looking statements set forth in the Company’s filings with the SEC, including its Annual Report on Form
10-K and its Quarterly Reports on Form 10-Q filed with the SEC. 

The Company and Intrexon acknowledge and agree that no party to this Agreement has made or makes any representations or warranties with
respect to the transactions contemplated hereby other than those specifically set forth in this Article III and the Transaction Documents. 

ARTICLE IV 
 OTHER
AGREEMENTS OF THE PARTIES 
 4.1 Transfer Restrictions. 

(a) The Securities may only be disposed of in compliance with state and federal securities laws, including the requirement not to trade in the
Securities while in possession of material non-public information. In connection with any transfer of Shares other than pursuant to an effective registration statement, to the Company or to an Affiliate of
Intrexon or in connection with a pledge as contemplated in Section 4.1(c), the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the
form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Shares under the Securities Act. As a condition of transfer, any such transferee
shall agree in writing to be bound by the terms of this Agreement and shall have the rights of Intrexon under this Agreement. 

  
 16 







 (b) Intrexon agrees to the imprinting, so long as is required by this Section 4.1, of a
legend on any of the Securities in the following form: 
 THIS SECURITY HAS NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION
OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS
EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT WITH A REGISTERED
BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT OR OTHER LOAN SECURED BY SUCH SECURITIES. 

(c) The Company acknowledges and agrees that Intrexon may from time to time pledge pursuant to a bona fide margin agreement with a registered
broker-dealer or grant a security interest in some or all of the Securities to a financial institution that is an “accredited investor” as defined in Rule 501(a) under the Securities Act and who agrees to be bound by the provisions of this
Agreement and, if required under the terms of such arrangement, Intrexon may transfer pledged or secured Securities to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval of the Company and no legal opinion of
legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be required of such pledge. At Intrexon’s expense, the Company will execute and deliver such reasonable documentation as
a pledgee or secured party of Securities may reasonably request in connection with a pledge or transfer of the Securities. 
 (d) Intrexon
agrees that the removal of the restrictive legend from certificates representing Securities as set forth in this Section 4.1 is predicated upon the Company’s reliance that Intrexon will sell any Securities pursuant to either the
registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if Securities are sold pursuant to a Registration Statement, they will be sold in compliance with the
plan of distribution set forth therein. 

  
 17 







 4.2 Furnishing of Information. For a period of one year after the date of this Agreement,
the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act. During this one-year period, if the Company is not required to file reports pursuant to the Exchange Act, it will prepare and furnish to Intrexon and make publicly available in accordance with Rule 144 such information as is
required for Intrexon to sell the Shares under Rule 144. The Company further covenants that it will take such further action as any holder of Shares may reasonably request, to the extent required from time to time to enable such Person to sell such
Shares without registration under the Securities Act within the requirements of the exemption provided by Rule 144. 
 4.3
Integration. The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that could reasonably be expected to be integrated with
the offer or sale of the Shares in a manner that would require the registration under the Securities Act of the sale of the Shares to Intrexon or that would be integrated with the offer or sale of the Shares for purposes of the rules and regulations
of any Trading Market such that it would require shareholder approval prior to the closing of such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction. 

4.4 Securities Laws Disclosure; Publicity. On or before 9:00 a.m., New York City time, on the Business Day immediately following the
date hereof, the Company shall issue a press release (the “Press Release”) reasonably acceptable to Intrexon disclosing all material terms of the transactions contemplated hereby. On or before 5:30 p.m., New York City time, on the
fourth Trading Day immediately following the execution of this Agreement, the Company will file a Current Report on Form 8-K with the Commission describing the terms of the Transaction Documents (and including
as exhibits to such Current Report on Form 8-K the material Transaction Documents (including, without limitation, this Agreement)). Notwithstanding the foregoing, the Company shall not publicly disclose the
name of Intrexon or an Affiliate of Intrexon, or include the name of Intrexon or an Affiliate of Intrexon in any press release or filing with the Commission (other than the Registration Statement) or any regulatory agency or Trading Market, without
the prior written consent of Intrexon, except (i) as required by federal securities law in connection with the filing of final Transaction Documents (including signature pages thereto) with the Commission and (ii) to the extent such
disclosure is required by law, request of the Staff of the Commission or Trading Market regulations, in which case the Company shall provide Intrexon with prior written notice of such disclosure permitted under this subclause (ii). 

4.5 Indemnification of Intrexon. 

(a) The Company will indemnify and hold Intrexon and its directors, officers, stockholders, members, partners, employees and agents (and any
other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title), each Person who controls Intrexon (within the meaning of Section 15 of the Securities Act and
Section 20 of the Exchange Act), and the directors, officers, stockholders, agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title
or any other title) of such controlling person (each, a “Purchaser Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments,


  
 18 







 
amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any Purchaser Party may suffer or incur (i) as a result of any breach of any of
the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents or (ii) arising out of, in connection with, or as a result of the execution or delivery of this Agreement, any
other Transaction Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or thereunder or the consummation of the transactions contemplated hereby or
thereby. The Company will not be liable to any Purchaser Party under this Agreement to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s breach of any of the representations,
warranties, covenants or agreements made by Purchaser Party in this Agreement or in the other Transaction Documents. 
 (b) Promptly after
receipt by any Person (the “Indemnified Person”) of notice of any demand, claim or circumstances which would or might give rise to a claim or the commencement of any action, proceeding or investigation in respect of which indemnity
may be sought pursuant to Section 4.5(a), such Indemnified Person shall promptly notify the Company in writing and the Company shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified
Person, and shall assume the payment of all fees and expenses; provided, however, that the failure of any Indemnified Person so to notify the Company shall not relieve the Company of its obligations hereunder except to the extent that the Company is
actually and materially and adversely prejudiced by such failure to notify. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such
Indemnified Person unless: (i) the Company and the Indemnified Person shall have mutually agreed to the retention of such counsel; (ii) the Company shall have failed promptly to assume the defense of such proceeding and to employ counsel
reasonably satisfactory to such Indemnified Person in such proceeding; or (iii) in the reasonable judgment of counsel to such Indemnified Person, representation of both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. The Company shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably withheld, delayed or conditioned. Without the prior
written consent of the Indemnified Person, which consent shall not be unreasonably withheld, delayed or conditioned, the Company shall not effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or
could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Person from all liability arising out of such proceeding, does not admit
liability on the part of or attribute fault to any Indemnified Person and contains a provision requiring confidentiality with respect to the facts and circumstances of the dispute and of the existence and amount of the settlement. 

4.6 Reservation of Preferred Stock. As of the date hereof, the Company has reserved and the Company shall continue to reserve and keep
available at all times, a sufficient number of shares of Series C Preferred Stock for the purpose of enabling the Company to issue Shares pursuant to this Agreement. 

4.7 Waiver and Consent. Intrexon elects not to participate in the Series B Preferred Financing and in connection therewith
(a) waives any and all contractual rights to participate in the Series B Financing and (b) consents to the registration rights being granted to the investors in the Series B Financing. 

  
 19 







 4.8 Confidentiality After The Date Hereof. Intrexon covenants that until such time as the
transactions contemplated by this Agreement and such other material non-public information related to the Company in possession of Intrexon are publicly disclosed by the Company as described in
Section 4.4, Intrexon will maintain the confidentiality of all non-public information disclosed to it in connection with the transactions contemplated hereby (including the existence and terms of such
transactions). 
 4.9 Delivery of Shares After Closing. The Company shall deliver, or cause to be delivered, the respective Shares
purchased by Intrexon to Intrexon within three Trading Days of the Closing Date (unless Intrexon has specified to the Company at the time of execution of this Agreement that it shall settle “delivery versus payment” in which case such
Shares shall be delivered on or prior to the Closing Date). 
 4.10 Form D; Blue Sky Filings. The Company agrees to timely file a Form
D with respect to the Shares as required under Regulation D and to provide a copy thereof, promptly upon request of Intrexon. The Company shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption
for, or to qualify the Shares for, sale to Intrexon at the Closing under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence of such actions promptly upon request of Intrexon. 

4.12 Use of Proceeds. The Company intends to use the net proceeds of this offering after payment of the expenses of the offering for the
funding of its AG013 research and clinical trials and for general corporate purposes, including working capital and shall not use such proceeds for the satisfaction of any portion of the Company’s debt (other than trade payables in the ordinary
course of the Company’s business and prior practices), or to redeem any Common Stock or Common Stock Equivalents. 
 4.13 Prepaid
Invoice Amount. The Per Share Exchange Price reflects an overpayment of the Debt equal to $8,589.28. The Company and Intrexon agree that such amount shall be treated as a prepaid amount by the Company and will be deducted from future invoices
issued to the Company by Intrexon. 
 4.14 Termination. Notwithstanding anything herein to the contrary, this Agreement may be
terminated at any time by Intrexon (with respect to the obligations of Intrexon) or the Company, upon written notice to the other party, if the Closing shall not have occurred on or before the date that is three months from the date hereof (the
“Outside Date”); provided, however, that the right to terminate this Agreement under this Section 4.13 shall not be available to any party whose (i) breach of any provision of this Agreement, (ii) failure to comply
with their obligations under this Agreement or (iii) actions not taken in good faith, shall have been the cause of, or shall have resulted in, the failure of the Closing to occur on or prior to the Outside Date or the failure of a condition in
Section 2.3 to be satisfied at such time.

in (and without limiting any similar provisions of) any of the other Transaction Documents, whenever Intrexon exercises a right, election, demand or option under a Transaction Document and the Company does not timely and materially perform its
related obligations within the periods therein provided, then Intrexon may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without
prejudice to its future actions and rights. 
 5.14 Replacement of Shares. If any certificate or instrument evidencing any Shares is
mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of
evidence reasonably satisfactory to the Company and the Transfer Agent of such loss, theft or destruction and the execution by the holder thereof of a customary lost certificate affidavit of that fact and an agreement to indemnify and hold harmless
the Company and the Transfer Agent for any losses in connection therewith or, if required by the Transfer Agent, a bond in such form and amount as is required by the Transfer Agent. The applicants for a new certificate or instrument under such
circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Shares. If a replacement certificate or instrument evidencing any Shares is requested due to a mutilation thereof, the Company may require
delivery of such mutilated certificate or instrument as a condition precedent to any issuance of a replacement. 
 5.15 Remedies. In
addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, Intrexon and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary
damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby agrees to waive and not to assert in any action for specific performance of any such obligation
the defense that a remedy at law would be adequate. 
 5.16 Payment Set Aside. To the extent that the Company makes a payment or
payments to Intrexon pursuant to any Transaction Document or Intrexon enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other person under any law (including, without limitation, any
bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as
if such payment had not been made or such enforcement or setoff had not occurred. 
 5.17 [Reserved]. 

5.18 No Promotion. The Company agrees that it will not, and shall cause each of its Subsidiaries to not, without the prior written
consent of Intrexon, use in advertising, publicity, or otherwise the name of Intrexon, its affiliates or any of their respective partners or employees, nor 

  
 23 







 
any trade name, trademark, trade device, service mark, symbol or any abbreviation, contraction or simulation thereof owned by such persons. The Company further agrees that it shall obtain
the written consent of Intrexon prior to the Company’s or any of its Subsidiaries’ issuance of any public statement detailing the acquisition of Securities by Intrexon pursuant to this Agreement. 

5.19 Construction. The parties agree that each of them and/or their respective counsel has reviewed and had an opportunity to revise the
Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of the Transaction Documents or any amendments hereto.

 5.20 Exculpation. Intrexon acknowledges that it is not relying upon any person, firm or corporation, other than the Company and its
officers and directors (acting in their capacity as representatives of the Company), in deciding to invest and in making its investment in the Company. 

5.21 Company Acknowledgement. The Company acknowledges and agrees that (i) Intrexon is participating in the transactions
contemplated by this Agreement and the other Transaction Documents at the Company’s request and the Company has concluded that such participation is in the Company’s best interest and is consistent with the Company’s objectives and
(ii) Intrexon is acting solely in the capacity of an arm’s length purchaser. The Company further acknowledges that Intrexon is acting or has acted as an advisor, agent or fiduciary of the Company (or in any similar capacity) with respect
to this Agreement or the other Transaction Documents and any advice given by Intrexon or any of its respective representatives in connection with this Agreement or the other Transaction Documents is merely incidental to Intrexon’s acquisition
of Shares. The Company further represents to Intrexon that the Company’s decision to enter into this Agreement has been based solely on the independent evaluation of the transactions contemplated hereby by the Company and its representatives.

 Exhibit A 

Certificate of Designation 






 Exhibit B 

Form of Legal opinion of Company Counsel 

Based upon and subject to the foregoing, it is our opinion as of this date that: 

1. Based solely upon the certificate of good standing, dated
[                 , 2017], issued by the State of Florida, the Company is a corporation validly existing and in good standing under the laws of the State of Florida.

 2. The Company has the corporate power and authority to execute, deliver and perform its obligations under the Transaction Documents,
including, without limitation, to issue and deliver the Shares as contemplated by the Agreement. Each of the Transaction Documents has been duly authorized by all necessary corporate action and each has been duly executed and delivered on behalf of
the Company, and each is a legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms. 

3. The execution and delivery by the Company of the Transaction Documents, and the performance by the Company of its obligations thereunder as
of the date hereof, do not violate the Company’s Articles of Incorporation or Bylaws, do not constitute a default under or a material breach of any material agreement of the Company that has not otherwise been waived and, to our knowledge, do
not (a) violate any U. S. Federal or state statute, rule or regulation applicable to the transactions contemplated by the Transaction Documents or (b) violate any order, writ, judgment, injunction, decree, determination or award which has
been entered against the Company and of which such counsel is aware, except, with respect to clauses (a) and (b), where such violation would not materially and adversely affect the Company. 

4. The Company has the authorized capital stock as set forth in the SEC Documents. The Securities have been duly authorized, and when issued
and sold in accordance with the Securities Purchase Agreement, will be validly issued and non-assessable. 

5. No approval, authorization or other action by, or notice to or filing with, any governmental authority is required in connection with the
execution, delivery and performance by the Company of the Transaction Documents, except (a) those that have been obtained or made and are in full force and effect, and (b) any filings required by Regulation D promulgated under the
Securities Act of 1933, as amended, or by state securities laws. 
 6. To our knowledge, there is no action, proceeding or investigation
pending or overtly threatened against the Company before any court or administrative agency that questions the validity of the Transaction Documents or that could reasonably be expected to result, either individually or in the aggregate, in a
material adverse effect on the Company. 
 7. Assuming the truth and accuracy of the representations made by the Company and Intrexon in the
Debt Conversion Agreement, the sale and issuance of the Shares in conformity with the terms of the Transaction Documents constitute transactions that are exempt from the registration requirements of the Securities Act of 1933, as amended, subject to
the timely filing of a Form D pursuant to Regulation D. 






 8. The Company is not, after giving effect to the issuance of the Shares, an “investment
company” as defined in the Investment Company Act of 1940, as amended. 
 9. To our knowledge and except as set forth in the SEC
Documents with respect to Intrexon Corporation and the Koski Family Limited Partnership, there are no written contracts, agreements or understandings between the Company and any person granting such person the right (other than rights which have
been waived in writing or otherwise satisfied) to require the Company to include any securities of the Company in any registration statement.
