Items (a) through (i) are sometimes hereinafter referred to collectively as the “Agreements”. We have also examined such other matters of law, and originals or copies of such other documents, corporate records and other materials, that we consider relevant for purposes of this opinion. In giving this opinion, we have assumed, with your permission, the genuineness of all signatures, the legal capacity of natural persons and the authenticity and completeness of all documents we have examined. As to questions of fact relevant to this opinion, with your permission and without any independent investigation or verification, we have relied upon, and assumed the accuracy of, the representations and warranties of each party in the Agreements and have relied upon certificates of officers of the Company and written statements of certain public officials which we consider necessary or advisable for the purpose of rendering this opinion. May __, 2015 For purposes of this opinion, we are assuming that the Buyers have all requisite power and authority, and have taken any and all necessary corporate, partnership or limited liability company action, to execute and deliver the Agreements, and we are assuming that the representations and warranties made by the Buyers in the Agreements and pursuant thereto are true and correct. We are also assuming that the Buyers have purchased the Notes and Warrants for value, in good faith and without notice of any adverse claims within the meaning of the UCC in effect in the State of Delaware (“Delaware UCC”) and that there are no other extrinsic agreements or understandings among the parties to the Agreements that would modify or otherwise interpret the terms thereof. We also have assumed, with your permission and without any independent verification, compliance by each party to the Agreements with its agreements in the respective Agreements, and that each of the Agreements constitutes the legal, valid and binding obligation of each party to it (other than the Company and the Subsidiary) and is enforceable against each such party in accordance with its terms. We note that some of the Agreements provide that they are to be governed by the law of the State of New York. Except with respect to those portions of the Agreements that are governed by the Delaware General Corporation Law, our opinions regarding the validity, binding effect, and enforceability of the Agreements are given as though each of the Agreements were governed by the internal laws of the State of California. We call your attention to the fact that the Company is incorporated in the State of Nevada and the Subsidiary is incorporated in the State of Delaware and that the Company and the Subsidiary may hold assets in foreign countries and own securities of companies organized under the laws of foreign jurisdictions. For purposes of this opinion, we have assumed with your permission that the laws of the State of Nevada are identical to those of the State of California. We render no opinion with regard to the applicability of any foreign laws. We express no opinion except to the extent that Article 9 of the Delaware UCC governs the creation or perfection of the security interests referred to in this opinion. As used in this opinion, the expression “to our knowledge”, “known to us” or similar language with reference to matters of fact means that, after an examination of documents made available to us by the Company, and after inquiries of officers of the Company, but without any further independent factual investigation, we find no reason to believe that the opinions expressed herein are factually incorrect. When reference is made in this opinion to our “knowledge” of certain matters or to matters “known to us”, it means the actual present knowledge and conscious awareness of those matters by the attorneys at our firm involved in acting as counsel to the Company. Except to the extent expressly set forth herein, we have not undertaken any independent investigation to determine the existence or absence of any fact, and no inference as to our knowledge of the existence or absence of any fact should be drawn from our representation of the Company or the rendering of the opinion set forth below. May __, 2015 Our opinion set forth in paragraph 1 below with respect to the Company is given as of the date of, and is based solely upon, a Certificate of Good Standing from the Secretary of State of Nevada dated April 30, 2015, and the State of California dated April 29, 2015. Our opinion set forth in paragraph 1 below with respect to the Subsidiary is given as of the date of, and is based solely upon, a Certificate of Good Standing from the Secretary of State of Delaware dated April 29, 2015, and the State of California dated April 29, 2015. For purposes of the opinions contained in paragraph 10 below, we have assumed that each of the Company and the Subsidiary has rights in its personal property collateral. No opinion is being rendered (i) whether the properties described in any security agreement are the properties and interests intended to be covered thereby; (ii) the priority of any security interest; or (ii) with respect to a security interest in collateral consisting of a debtor's rights under any rule of law, statute or regulation, or contract, permit, license, franchise or other agreement containing any term, that prohibits, restricts, or requires the consent of any individual or entity (“Person”) to, the assignment or transfer of, or creation, attachment, or perfection of, a security interest in any such rights, and such prohibition or restriction has not been waived by, or such consent obtained from, such Person, or such prohibition or restriction is not ineffective pursuant to Sections 9-406 through 9-409 of the Delaware UCC. In addition we call your attention to the following insofar as Article 9 of the Delaware UCC is applicable: (i) the effectiveness of financing statements generally lapses five years from the date of filing unless a continuation statement is filed within six months prior to such termination in accordance with Section 9-515; (ii) Section 9-507(c) provides that if the name that a filed financing statement provides for a debtor becomes insufficient as the name of the debtor under Section 9-503(a) so that a filed financing statement becomes seriously misleading under Section 9-506, the filing is not effective to perfect a security interest in collateral acquired by the debtor more than four months after such change unless an amendment to the financing statement which renders the financing statement not seriously misleading is filed before the expiration of that period;

THIS WARRANT CERTIFIES THAT, for good and valuable consideration, [HOLDER] (together with any successor or permitted assignee or transferee of this Warrant, “Holder”) is entitled to purchase up to [●] shares of fully paid and non-assessable common stock, par value $0.0001 per share (the “Common Stock”), of Aja HoldcoPacific Ethanol, Inc., a Delaware corporation (the “Company”), at and have represented the Company in connection with that certain Senior Secured Note Amendment Agreement (the “Note Amendment Agreement”) entered into by and among the Company and the Holders named therein (collectively, the “Holders”) pursuant to which the Company issued to the Holders certain shares (“Shares”) of the Company’s common stock, $0.001 par value per share (the ”Common Stock”) and warrants (“Warrants”) exercisable for shares of Common Stock, and may issue additional shares of Common Stock (“Additional Common Shares”). Pursuant to the Note Amendment Agreement, the Company also has entered into a Registration Rights Agreement with the Holders (the “Registration Rights Agreement”) pursuant to which the Company agreed, among other things, to register the Registrable Securities (as defined in the Registration Rights Agreement), including the shares of Common Stock issuable pursuant to the terms of the Warrants (“Warrant PriceShares”), all under the Securities Act of 1933, as amended (the “1933 Act”). In connection with the Company’s obligations under the Registration Rights Agreement, on ____________ ___, 20__, the Company filed a Registration Statement on Form [S-1] (File No. 333-_____________) (the “Registration Statement”) with the Securities and Exchange Commission (the “SEC”) relating to the Registrable Securities which names each of the Holders as a selling security holder thereunder. The names of the Selling Stockholders to whom this opinion relates and the numbers of Shares that each Selling Stockholder may resell under the Registration Statement are set forth above under the column “Shares to be Offered” in the section of the Registration Statement and Prospectus entitled “Selling Stockholders” in the column “Shares to be Offered Pursuant to the Registration Statement.” For purposes of this opinion, we have reviewed a copy of the Registration Statement and Prospectus, and such other and further information and documents as we have deemed advisable. In connection with the foregoing, we have examined copies of resolutions of the Board of Directors of the Company, the securities described in the Registration Statement and such other agreements, instruments and documents as we have deemed relevant or necessary as a basis for the opinions hereinafter set forth. In making such examination, we have assumed the genuineness of all signatures on all original documents and the conformity to original documents of all copies submitted to us as conformed, photostat or other copies. As to matters of fact material to such opinions, we have, when relevant facts were not independently established, relied upon statements and certificates furnished to us. Based upon and subject to the provisions foregoing, we render the following opinions: 1. The Registration Statement has become effective under the Act, and to the best of our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued, and no proceedings for that purpose have been instituted or threatened. 2. The Shares are, and upon due issuance of the Additional Common Shares in accordance with the terms of the Note Amendment Agreement, the Additional Common Shares will be, and conditions set forth upon due exercise of the Warrants in accordance with their terms including receipt of the consideration therefor, the Warrant Shares will be, duly and validly issued, fully paid and non-assessable, and not subject to the preemptive rights of any stockholder of the Company. As with any selling stockholders’ registration statement, the Shares, any Additional Common Shares and the Warrant Shares are restricted securities, but may be sold pursuant to the Registration Statement. The normal restrictive legend appearing thereto may be removed following the sale of such securities or the placement in street name of the selling broker in contemplation of imminent sale with the understanding that, if the sale is not consummated, the certificates will be returned to you for relegending. Notwithstanding the foregoing, we may in the future advise you as to certain institutional type investors or foreign investors from whose shares the restrictive legend may be removed prior to placement into street name based on their status. Our opinion shall not apply to resales occurring during any period that we or the Company may advise you in writing that the Registration Statement is not current. In such event, no resales of Shares, Additional Common Shares or Warrant Shares by Selling Stockholders shall be effected pursuant to our opinion until we confirm that our opinion may again be relied upon to effect resales by Selling Stockholders. This opinion is rendered to American Stock Transfer & Trust Company and is not to be relied upon by any other person. We undertake no responsibility to update this Warrantinformation to reflect facts occurring after the date hereof.

The letter also indicated that the Company will be provided with a compliance period of 180 calendar days, or until January 13, 2020, in which to regain compliance pursuant to Nasdaq Listing Rule 5810(c)(3)(A). The letter further provided that if, at any time during the 180-day period, the closing bid price of the Company’s common stock is at least $1.00 for a minimum of ten consecutive business days, Nasdaq will provide the Company with written confirmation that it has achieved compliance with the minimum bid price requirement. If the Company does not regain compliance by January 13, 2020, an additional 180 days may be granted to regain compliance if the Company (i) meets the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market (except for the bid price requirement) and (ii) provides written notice of its intention to cure the deficiency during the second 180-day compliance period. On May 24, 2013, GS CleanTech Corporation (“GS CleanTech”), filed a suit in the United States District Court for the Eastern District of California, Sacramento Division (Case No.: 2:13-CV-01042-JAM-AC), naming the Company as a defendant. On August 29, 2013, the case was transferred to the United States District Court for the Southern District of Indiana and made part of the pre-existing multi-district litigation involving GS CleanTech and multiple defendants. The suit alleged infringement of a patent assigned to GS CleanTech by virtue of certain corn oil separation technology in use at one or more of the ethanol production facilities in which the Company has an interest, including Pacific Ethanol Stockton LLC (“▇▇ ▇▇▇▇▇▇▇▇”), located in Stockton, California. The complaint sought preliminary and permanent injunctions against the Company, prohibiting future infringement on the patent owned by GS CleanTech and damages in an unspecified amount adequate to compensate GS CleanTech for the alleged patent infringement, but in any event no less than a reasonable royalty for the use made of the inventions of the patent, plus attorneys’ fees. The Company answered the complaint, counterclaimed that the patent claims at issue, as well as the claims in several related patents, are invalid and unenforceable and that the Company is not infringing. The Company does not itself use any corn oil separation technology and may seek a dismissal on those grounds. On March 17 and March 18, 2014, GS CleanTech filed suit naming as defendants two Company subsidiaries: ▇▇ ▇▇▇▇▇▇▇▇ and Pacific Ethanol Magic Valley, LLC (“PE Magic Valley”) as defendants. The claims were similar to those filed against the Company in May 2013. These two cases were transferred to the multi-district litigation division in United States District Court for the Southern District of Indiana, where the case against the Company was pending. Although ▇▇ ▇▇▇▇▇▇▇▇ and PE Magic Valley do separate and market corn oil, the Company, ▇▇ ▇▇▇▇▇▇▇▇ and PE Magic Valley strongly disagree that either of the subsidiaries use corn oil separation technology that infringes the patent owned by GS CleanTech. In a January 16, 2015 decision, the District Court for the Southern District of Indiana ruled in favor of a stipulated motion for partial summary judgment for the Company, ▇▇ ▇▇▇▇▇▇▇▇ and PE Magic Valley finding that all of the GS CleanTech patents in the suit are invalid and, therefore, not infringed. GS CleanTech has said it will appeal this decision when the remaining claim in the suit has been decided. The only remaining claim alleged that GS CleanTech inequitably conducted itself before the United States Patent and Trademark Office when obtaining the patents at issue. A trial in the District Court for the Southern District of Indiana was conducted in October 2015 on that single issue as well as whether GS CleanTech’s behavior during prosecution of the patents rendered this an “exceptional case” which would allow the District Court to award the defendants reimbursement of their attorneys’ fees expended for defense of the case. On September 15, 2016, the District Court issued an Order finding that GS CleanTech, the inventors and GS CleanTech’s counsel committed inequitable conduct in the prosecution of the GS CleanTech patents before the United States Patent and Trademark Office. As a result, the District Court issued a Final Judgment on September 15, 2016 dismissing with prejudice all of GS CleanTech’s cases against the defendants, including the Company, ▇▇ ▇▇▇▇▇▇▇▇ and PE Magic Valley. The District Court’s ruling of inequitable conduct results in the unenforceability of the GS CleanTech patents against third parties, and also enables the defendants to pursue reimbursement of their costs and attorneys’ fees from GS CleanTech and its counsel. GS CleanTech subsequently appealed the District Court’s finding that all of the GS CleanTech patents were invalid and its finding that the inventors and GS CleanTech’s counsel committed inequitable conduct. The appeal was heard by the Court of Appeals for the Federal Circuit on December 3, 2019, and the Court’s decision is pending. On October 11, 2016, Pacific Ethanol Pekin, LLC (“PE Pekin”) received a notice from the Illinois EPA (“IEPA”), citing a number of air quality violations. The notice arises out of self-reported deviations at the Dry Mill at Pekin in early 2016, specifically emissions from the Thermal Oxidizer (NOx), the CO2 Scrubber (VOM, Acetaldehyde), and the methanator flare. The Dry Mill was shut down in April 2016 primarily to address these issues, and among other things a new burner control system was installed in the boiler. All of the cited issues have been resolved except NOx emissions. PE Pekin has submitted an application for a permit modification, within whose parameters the Dry Mill will be able to operate without violating NOx standards. IEPA has agreed that the NOx issues can be resolved through the permit modification, and has suspended its enforcement action, pending processing of the application. On January 8, 2018, PE Pekin was sued by the State of Illinois at the request of the IEPA alleging certain violations of the Company’s waste water discharge permit and Section 301(a) of the Clean Water Act, 33 U.S.C. § 1311(a). PE Pekin had invited the suit in order to preempt a citizen suit being prepared by the Sierra Club and Prairie Rivers Network. The suit arises out of self-reported deviations from temperature, chlorine and ammonia limits in the Company’s National Pollutant Discharge Elimination System (NPDES) Permit. The chlorine and ammonia exceedances were transitory in nature and are not expected to be a serious issue. The thermal exceedances, however, were frequent during the summer months. PE Pekin has since obtained the results of a thermal mixing study, which provides the basis for the company to seek a modification of the Permit relaxing the thermal limits. On August 20, 2018, an agreed interim order was signed which stays the lawsuit and lays out the pathway to a final settlement of the case. On October 19, 2018, PE Pekin filed an application for an amendment to its NPDES Permit proposing alt
