not offer or sell any of the Shares or interest therein or otherwise, in violation of the Securities Act of 1933, as amended (the Securities Act). IOWC and Code further acknowledges that neither he nor it has in mind any sale of the
Shares currently or after the passage of a fixed or determinable period of time or upon the occurrence or non-occurrence of any predetermined



---

events or consequence; and that he or it has no present or contemplated agreement, undertaking, arrangement, obligation, indebtedness or commitment providing
for or which is likely to compel a disposition of the Shares and is not aware of any circumstances presently in existence that are likely in the future to prompt a disposition of the Shares.

in a generally acceptable form, to the effect that such securities to be sold, assigned or transferred may be sold, assigned or transferred pursuant to an exemption from such registration requirements; (ii) any sale of such securities made in
reliance on Rule 144 under the Securities Act (Rule 144) may be made only in accordance with the terms of Rule 144 and further, if Rule 144 is not applicable, any resale of such securities under circumstances in which the seller (or the
person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the Securities Act) may require compliance with some other exemption under the Securities Act or the rules and regulations of the Securities and
Exchange Commission (the SEC) thereunder; and (iii) neither BioLargo nor any other person is under any obligation to register such securities under the Securities Act or any state securities laws or to comply with the terms and
conditions of any exemption thereunder. BioLargo reserves the right to place stop transfer instructions against the Shares and certificates for the Shares.

---

D. Notice of Claim. If a claim for Damages (a Claim) is to be made by
a party entitled to indemnification hereunder (an Indemnified Party) against the indemnifying party (the Indemnifying Party), the Indemnified Party shall give written notice (a Claim Notice) to the Indemnifying
Party, which notice shall specify whether the Claim arises as a result of a claim by a person against the Indemnified Party (a Third Party Claim) or whether the Claim does not so arise (a Direct Claim), and shall also specify
(to the extent that the information is available) the factual basis for the Claim and the amount of the Damages, if known. If the Claim is a Third Party Claim, the Indemnified Party shall provide the Claim Notice as soon as practicable after such
party becomes aware of any fact, condition or event which may give rise to Damages for which indemnification may be sought under this section. If any lawsuit or enforcement action is filed against any Indemnified Party, written notice thereof shall
be given to the Indemnifying Party as promptly as practicable (and in any event within 15 calendar days after the service of the citation or summons). The failure of any Indemnified Party to give timely notice hereunder shall not affect rights to
indemnification hereunder, except to the extent that the Indemnifying Party has been damaged by such failure.

E. Direct
Claims. With respect to any Direct Claim, following receipt of the Claim Notice from the Indemnified Party, the Indemnifying Party shall have 30 days to make such investigation of the Claim as is considered necessary or desirable. For the
purpose of such investigation, the Indemnified Party shall make available to the Indemnifying Party sufficient information to substantiate the Claim, together with all such other non-privileged information as the Indemnifying Party may reasonably
request. If both parties agree at or prior to the expiration of such 30-day period (or any mutually agreed upon extension thereof) to the validity and amount of such Claim, the Indemnifying Party shall immediately pay to the Indemnified Party the
full agreed upon amount of the Claim. If the parties have not so agreed to the validity and/or amount of the Claim, then the parties shall proceed in the manner set forth in the following sentence. If the Closing shall have occurred under this
Agreement, the matter shall be resolved pursuant to the arbitration provisions contained in Section 12M; and if the Closing shall not have occurred under this Agreement, the Indemnified Party may bring an action against the Indemnifying Party
in any court located in Orange County, California.

F. Third Party Claims. With respect to a Third Party Claim, if
after receipt of the Claim Notice the Indemnifying Party acknowledges in writing to the Indemnified Party that the Indemnifying Party shall be obligated under the terms of its indemnity hereunder in connection with such lawsuit or action, the
Indemnifying Party shall be entitled, if it so elects at its own cost, risk and expense, (A) to take control of the defense and investigation of such lawsuit or action, (B) to employ and engage attorneys



---

of its own choice, but, in any event, reasonably acceptable to the Indemnified Party, to handle and defend the same unless the named parties to such action
or proceeding (including any impleaded parties) include both the Indemnifying Party and the Indemnified Party and the Indemnified Party has been advised in writing by counsel that there may be one or more legal defenses available to such Indemnified
Party that are different from or additional to those available to the Indemnifying Party, in which event the Indemnified Party shall be entitled, at the Indemnifying Partys cost, risk and expense, to separate counsel of its own choosing, and
(C) to compromise or settle such lawsuit or action, which compromise or settlement shall be made only with the written consent of the Indemnified Party, such consent not to be unreasonably withheld.

If the Indemnifying Party fails to assume the defense of such Claim within 30 calendar days after receipt of the Claim Notice, the
indemnified party against which such Claim has been asserted will (upon delivering notice to such effect to the Indemnifying Party) have the right to undertake, at the Indemnifying Partys cost and expense, the defense, compromise or settlement
of such Claim on behalf of and for the account and risk of the Indemnifying Party. If the Indemnified Party assumes the defense of the Claim, the Indemnified Party will keep the Indemnifying Party reasonably informed of the progress of any such
defense, compromise or settlement. The Indemnifying Party shall be liable for any settlement of any action effected pursuant to and in accordance with this Section 9F and for any final judgment (subject to any right of appeal) and the
Indemnifying Party agrees to indemnify and hold harmless an Indemnified Party from and against any Damages by reason of such settlement or judgment. If there is a dispute as to the indemnification obligations of any party under this Section 9F,
then the parties shall proceed in the manner set forth in the following sentence. If the Closing shall have occurred under this Agreement, the matter shall be resolved pursuant to the arbitration provisions contained in Section 12M; and if the
Closing shall not have occurred under this Agreement, the Indemnified Party may bring an action against the Indemnifying Party in any court located in Orange County, California

G. Remedies Cumulative. The foregoing indemnification provisions are in addition to, and not in derogation of, any remedy at law
or in equity that any Party may have with respect to this Agreement and the transactions contemplated hereby.

understanding of the parties with respect to the entire subject matter of this Agreement, and any and all prior discussions, negotiations, commitments and understandings, whether oral or otherwise, related to the subject matter of this Agreement are
hereby merged herein.

C. Assignment. No party may assign this Agreement, and any attempted or purported assignment
or any delegation of any partys duties or obligations arising under this Agreement to any third party or entity shall be deemed to be null and void, and shall constitute a material breach by such party of its duties and obligations under this
Agreement; provided that the Purchasers may assign their rights to purchase all or any portion of the Assets to a wholly-owned subsidiary presently existing or to be formed, whether such subsidiary is established under the laws of any State
or outside the United States. This Agreement shall inure to the benefit of and be binding upon any successors of each party by way of merger or consolidation.

D. Waiver and Amendment. No provision of this Agreement may be waived unless in writing signed by all the parties to this
Agreement, and waiver of any one provision of this Agreement shall not be deemed to be a waiver of any other provision. This Agreement may be amended only by a written agreement executed by all of the parties to this Agreement.

E. Governing Law. This Agreement has been made and entered into in the State of California and shall be construed in accordance
with the laws of the State of California without giving effect to the principles of conflicts of law thereof.

F.
Severability. Whenever possible each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be or become prohibited or invalid under
applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity without invalidating the remainder of such provision or the remaining provisions of this Agreement.

G. Captions. The various captions of this Agreement are for reference only and shall not be considered or referred to in resolving
questions of interpretation of this Agreement.

obligations under this Agreement, the prevailing

exercised from time to time.

K. Judicial Interpretation. Should any provision of this Agreement require judicial
interpretation, it is agreed that a court interpreting or construing the same shall not apply a presumption that the terms hereof shall be more strictly construed against any person by reason of the rule of construction that a document is to be

M. Dispute Resolution. Except for specific performance and other equitable relief provided for in this Agreement, if any
controversy or claim arising out of this Agreement cannot be settled by the parties, the controversy or claim shall be submitted to and settled by arbitration as hereinafter provided. The parties shall endeavor to agree upon a single arbitrator (the
Arbitrator) who shall be a retired judge provided by JAMS or equivalent organization (the Provider) and who shall then try all issues, whether of fact or law, and report a finding or judgment thereon. If the parties are
unable to agree upon the Arbitrator, each party shall provide the names of five retired judges from the Provider; then each party shall choose one of the names from the list proposed by the other, and from those two names the Arbitrator shall be
selected by the flip of a coin. Prior to commencement of the arbitration proceedings, the Arbitrator shall make a full disclosure to the parties of any prior engagement by any of the parties, or their attorneys or law firms. Any such prior

location;

addition to all other costs; and

any court located in Orange County, California.
