EX-99.1.A

Exhibit 99.1(a)

RULE 17J-1 CODE OF ETHICS

This Code of Ethics (the “Code”) has been adopted by Adams Street Private Equity Navigator Fund LLC, Adams Street Credit Solutions Fund and Adams Street Venture & Growth Fund (the “Funds”), in accordance with Rule 17j-1 under the Investment Company Act of 1940, as amended (the “1940 Act”). The purpose of the Code is to establish standards and procedures to detect and prevent activities by which a person, having knowledge of the investments and investment decisions of the Funds, may abuse their fiduciary obligation to the Funds, and otherwise to deal with the types of conflict of interest situations that Rule 17j-1 is intended to address.

The Code seeks to make evident the principle that the directors¹ and officers of the Funds, owe a fiduciary responsibility to the Funds and as such must conduct their personal security transactions in a way that does not interfere with the Funds’ investment decisions or otherwise provide them an unfair advantage due to their relationship with the Funds. Each provision of this Code and the general principles contained herein are required to be complied with by Access Persons (as defined below) of the Funds. Adams Street Advisors, LLC, the investment adviser to the Funds (the “Adviser”), is subject to a separate code of ethics in accordance with the 1940 Act and Investment Advisers Act of 1940, as amended (“Integrity Policy”). On at least an annual basis, the Adviser will present a report to the Funds’ board of directors (the “Board”) describing any issues arising under the Code or the Integrity Policy or procedures that occurred since the last report to the board, including information about material violations of such codes of ethics and/or procedures as well as the Adviser’s response and any action taken as a response to such violation.

It is the responsibility of each individual Access Person to seek to avoid any conflict of interest or even the potential perception of a conflict of interest. Technical compliance with the Code will not automatically insulate any Access Persons from scrutiny of transactions that show a pattern of compromise or abuse of the individual’s fiduciary obligations to the Funds. Accordingly, all Access Persons must seek to avoid any actual or potential conflicts between their personal interests and the interests of the Funds and their investors. In sum, all Access Persons shall place the interests of the Funds before their own personal interests. All Access Persons must read and retain this Code.

I.	Definitions

(K) “Limited Offering” means an offering that is exempt from registration under the 1933 Act pursuant to Section 4(2) or Section 4(6) thereof or pursuant to Rule 504, Rule 505, or Rule 506 thereunder.

(L) “Purchase or sale of a Covered Security” includes, among other things, the writing of an option to purchase or sell a Covered Security.

(M) “Security Held or to be Acquired” by the Funds means: (i) any Covered Security which, within the most recent 15 calendar days: (A) is or has been held by the Funds, one of its subsidiaries or an entity for which a Fund acts as adviser; or (B) is being or has been considered by the Funds for purchase by the Funds, one of their subsidiaries or an entity for which a Funds acts as adviser; and (ii) any option to purchase or sell, and any security convertible into or exchangeable for, a Covered Security described in the foregoing clause (i).

II.

Objectives and General Prohibitions

An Access Person may not engage in any investment transaction under circumstances in which the Access Person benefits from or interferes with the purchase or sale of investments by the Funds. In addition, Access Persons may not use information concerning the investments or investment intentions of the Funds, or their ability to influence such investment intentions, for personal gain or in a manner detrimental to the interests of the Funds.

Access Persons may not engage in conduct that is deceitful, fraudulent or manipulative, or that involves false or misleading statements, in connection with the purchase or sale of investments by the Funds. In this regard, Access Persons should recognize that Rule 17j-1 makes it unlawful for any affiliated person of the Funds, or any affiliated person of an investment adviser for the Funds, in connection with the purchase or sale, directly or indirectly, by the person of a Security Held or to be Acquired by the Funds to:

(i) employ any device, scheme or artifice to defraud the Funds;

(ii) make any untrue statement of a material fact to the Funds or omit to state to the Funds a material fact necessary in order to make the statements made, in light of the circumstances under which they are made, not misleading;

(iii) engage in any act, practice or course of business that operates or would operate as a fraud or deceit upon the Funds; or

(iv) engage in any manipulative practice with respect to the Funds.

Access Persons should also recognize that a violation of this Code or of Rule 17j-1 may result in the imposition of: (1) sanctions as provided by Section VIII below; or (2) administrative, civil and, in certain cases, criminal fines, sanctions or penalties.

III.

Prohibited Transactions

The following are considered prohibited transactions:

An Access Person may not purchase or otherwise acquire direct or indirect Beneficial Ownership of any Covered Security, and may not sell or otherwise dispose of any Covered Security in which he or she has direct or indirect Beneficial Ownership, if he or she knows or should know at the time of entering into the transaction that a Fund has purchased or sold the Covered Security within the last 15 calendar days, or is purchasing or selling or intends to purchase or sell the Covered Security in the next 15 calendar days.

Investment Personnel of the Funds must obtain approval from the Funds before directly or indirectly acquiring Beneficial Ownership in any securities in an Initial Public Offering or in a Limited Offering. Such approval must be obtained from Legal and Compliance and the Chief Compliance Officer, unless the Chief Compliance Officer is the person seeking such approval, in which case such approval must be obtained from Legal and Compliance.

No Access Person shall recommend any transaction in any Covered Securities by any Fund without having disclosed to the Chief Compliance Officer his or her interest, if any, in such Covered Securities or the issuer thereof, including: the Access Person’s Beneficial Ownership of any Covered Securities of such issuer; any contemplated transaction by the Access Person in such Covered Securities; any position the Access Person has with such issuer; and any present or proposed business relationship between such issuer and the Access Person (or a party which the Access Person has a significant interest).

IV.

Reports by Access Persons

Personal Securities Holdings Reports

All Access Persons shall within 10 calendar days of the date on which they become Access Persons, and thereafter, within 45 calendar days after the end of each calendar year, disclose the title, number of shares and principal amount of all Covered Securities in which they have a Beneficial Ownership as of the date the person became an Access Person, in the case of such person’s initial report, and as of the last day of the year, as to annual reports. The information in such reports must be current as of a date no more than 45 calendar days before the report is submitted. A form of such report, which is hereinafter called a “Personal Securities

Holdings Report,” is attached as Schedule A. Each Personal Securities Holdings Report must also disclose the name of any broker, dealer or bank with whom the Access Person maintained an account in which any securities were held for the direct or indirect benefit of the Access Person as of the date the person became an Access Person or as of the last day of the year, as the case may be. Each Personal Securities Holdings Report shall state the date it is being submitted. Securities acquired in Limited Offerings and other holdings not commonly held in a brokerage account also must be included in such Securities Holdings Reports. An Access Person who fails to submit the Personal Securities Holdings Report within 10 calendar days of the date the person became an Access Person, in the case of an initial report, or within 45 calendar days of the end of the calendar year, in the case of an annual report, may be prohibited from engaging in any personal securities transactions that require pre-clearance under this Code until such certifications are submitted and may be subject to other sanctions.

Quarterly Securities Transaction Reports

Within 30 calendar days after the end of each calendar quarter, each Access Person shall make a written report of all transactions occurring in the quarter in a Covered Security in which he or she had any Beneficial Ownership. A form of such report, which is hereinafter called a “Quarterly Securities Transaction Report,” is attached as Schedule B.

A Quarterly Securities Transaction Report shall be in the form of Schedule B or such other form approved by the Chief Compliance Officer or Legal and Compliance and must contain the following information with respect to each reportable transaction:

(1)

Date and nature of the transaction (purchase, sale or any other type of acquisition or disposition);

(2)

Title, interest rate and maturity date (if applicable), number of shares and principal amount of each Covered Security involved and the price of the Covered Security at which the transaction was effected;

(3)

Name of the broker, dealer or bank with or through whom the transaction was effected; and

(4)

The date the report is submitted by the Access Person.

Independent Directors

Notwithstanding the reporting requirements set forth in this Section V, an Independent Director who would be required to make a report under this Section V solely by reason of being a director of the Funds is not required to file a Personal Securities Holding Report upon becoming a director of the Funds or an annual Personal Securities Holding Report. Such an Independent Director also need not file a Quarterly Securities Transaction Report unless such director knew or, in the ordinary course of fulfilling his or her official duties as a director of the Funds, should have known that, during the 15-day period immediately preceding or after the date of the transaction in a Covered Security by the Independent Director, such Covered Security is or was purchased or sold by the Funds or the Funds considered purchasing or selling such Covered Security.

Brokerage Account and Statements

Access Persons, except Independent Directors, shall:

within 30 calendar days after the end of each calendar quarter, identify the name of the broker, dealer or bank with whom the Access Person established an account in which any securities were held during the quarter for the direct or indirect benefit of the Access Person and identify any new account(s) and the date the account(s) were established. This information shall be included on the appropriate Quarterly Securities Transaction Report; and

instruct the brokers, dealers or banks with whom they maintain such an account to provide duplicate account statements to the Chief Compliance Officer.

Form of Reports

A Quarterly Securities Transaction Report may consist of broker statements or other statements that provide a list of all personal Covered Securities holdings and transactions in the time period covered by the report and contain the information required in a Quarterly Securities Transaction Report.

Responsibility to Report

Access Persons will be informed of their obligations to report; however, it is the responsibility of each Access Person to take the initiative to comply with the requirements of this Section V. Any effort by the Funds to facilitate the reporting process does not change or alter that responsibility. A person need not make a report hereunder with respect to transactions effected for, and Covered Securities held in, any account over which the person has no direct or indirect influence or control.

Disclaimers

Any report required by this Section V may contain a statement that the report will not be construed as an admission that the person making the report has any direct or indirect Beneficial Ownership in the Covered Security to which the report relates.

V.	Other Prohibitions

Confidentiality of the Funds’ Transactions.

Until disclosed in a public report to shareholders or to the SEC in the normal course, all information concerning the securities “being considered for purchase or sale” by the Funds shall be kept confidential by all Access Persons and disclosed by them only on a “need to know” basis. It shall be the responsibility of the Chief Compliance Officer to report any inadequacy found in this regard to the directors of the Funds.

Outside Business Activities and Directorships.

Access Persons may not engage in any outside business activities that may give rise to conflicts of interest or jeopardize the integrity or reputation of the Funds. Similarly, no such outside business activities may be inconsistent with the interests of the Funds. All directorships of public or private companies held by Access Persons shall be reported to the Chief Compliance Officer.

Gratuities.

Access Persons shall not, directly or indirectly, take, accept or receive gifts or other consideration in merchandise, services or otherwise of more than nominal value from any person, firm, company, association or other entity (other than such person’s employer), in each case, that does business, or proposes to do business, with the Funds.

VI.

Annual Certifications

Each Access Person is required to thoroughly read and maintain a copy of the Code. Upon initially becoming an Access Person and on an annual basis thereafter, Access Persons are required to attest that they understand the policies and procedures addressed in this Code and will comply and have complied with such policies and procedures. If an Access Person does not understand any part of this Code, it is such person’s duty to contact the Chief Compliance Officer for further explanation.

No less frequently than annually, the Funds will furnish, and the Board shall consider, a written report to the Board (i) describing any issues arising under the Code, including any material violations of the Code or procedures and actions taken by the Funds in response to such material violations and (ii) certifying that each Fund has adopted procedures reasonably necessary to prevent Access Persons from violating the Code.

VII. Obligation to Report Violations; Sanctions

Any violation of the Code should be brought to the immediate attention to the Chief Compliance Officer. Upon the investigation of the Chief Compliance Officer, the violation investigation will be presented to the Board. The Board, including a majority of the Independent Directors, will then decide on the appropriate sanctions. The sanctions may include, without limitation: suspension or termination of employment, a letter of censure and/or restitution of an amount equal to the difference between the price paid or received by the Funds and the more advantageous price paid or received by the offending person or any other sanction the Board may deem appropriate. Any member of the Board to which a violation of this Code relates must recuse himself or herself from any discussion or decision with respect to the handling and/or imposition of sanctions regarding such violation. No Access Person shall retaliate against any person who reported a violation of the Code.

VIII. Administration and Construction

The administration of the Code is the responsibility of the Chief Compliance Officer. The duties of the Chief Compliance Officer, with the assistance of Legal and Compliance, are as follows:

Maintain an accurate and current list of all Access Persons with an appropriate description of their job function and title as well as any reporting obligation that an Access Person may have in connection with their role at the Funds or any other business, and informing all Access Persons of their reporting obligations hereunder;

Provide Access Persons with the Code annually as well as provide training on the Code to Access Persons initially upon hiring and annually thereafter;

The Chief Compliance Officer shall maintain and cause to be maintained in an easily accessible place at the principal place of business of the 17j-1 Organization, the following records and must make these records available to the SEC at any time and from time to time for reasonable periodic, special or other examinations:

A copy of all codes of ethics adopted by the Funds pursuant to Rule 17j-1 that have been in effect at any time during the past five (5) years;

IX.

Confidentiality

All reports, duplicate account statements and other information filed or delivered to the Chief Compliance Officer or furnished to any other person pursuant to this Code shall be treated as confidential, but are subject to review as provided herein and by representatives of the SEC.

X.	Adoption and Amendments

This Code may not be materially amended or modified except in a written form that is approved by majority vote of the Independent Directors within six (6) months after the adoption of such amendments or modifications. Prior to approving any such material amendments or modifications, the Board, including a majority of Independent Directors, must be provided a certification of each of the Funds that it has adopted procedures reasonably necessary to prevent Access Persons from violating this Code (and, in the case of the Adviser, from the Integrity Policy). The Board must base its approval of any material changes to the Code on a determination that the Code contains provisions reasonably designed to prevent Access Persons from engaging in any unlawful actions described in subparagraph (b) of Rule 17j-1.
