A. Description of the Advisory Firm Sunstone Partners Management, LLC (“Sunstone Partners” or the “Firm”) is a Delaware limited liability company that commenced operations in 2015.1 The principal owners of the Firm are Gustavo Alberelli, Michael Biggee and Arneek Multani (the “Principals”), who hold their respective interests through Sunstone Partners Management Holdings, LP, the parent entity of Sunstone Partners. The Firm’s clients include the following: Sunstone Partners I, LP, and its associated co-investment fund, Sunstone Partners Co-Invest I, LP (“Fund I” and the “Fund I Co-Invest Vehicle,” respectively), Sunstone Partners II, LP, Sunstone Partners II-A, LP and Sunstone Partners Executive Fund II, LP (together, “Fund II”) and Sunstone Partners III-Main, LP, Sunstone Partners III-A, LP and Sunstone Partners Executive Fund III, LP (together, “Fund III”). The Funds are not registered under the Investment Company Act of 1940, as amended (the “Investment Company Act”), and the securities of the Funds are not registered under the Securities Act of 1933, as amended (the “Securities Act”). B. Types of Services Sunstone Partners provides discretionary investment advisory services to private investment funds organized as Delaware limited partnerships (each a “Fund” and collectively the “Funds”). Sunstone Partners GP-I, LLC, Sunstone Partners GP-II, LLC and Sunstone Partners GP-III, LLC (together with any future general partner that may be formed, each an “Advisory Affiliate” or “General Partner”) are affiliated with the Firm and serve as general partners to the Funds. Each Advisory Affiliate is a related person of Sunstone Partners. The Firm provides investment advice on, and manages investments in, growth equity-stage companies in the United States and Canada, focused on technology-enabled services. Growth equity has historically been considered both a branch of later stage venture capital and as lower middle market private equity. Within technology-enabled services, the Firm focuses primarily on certain select vertical segments: Cloud, Cybersecurity, Healthcare IT and Marketing Services. The Firm offers investment advice solely with respect to the investments made by the Funds. The Firm’s services consist of investigating, identifying, and evaluating investment opportunities, structuring, negotiating and executing investments on behalf of the Funds, managing and monitoring the performance of such investments, and advising as to the disposition of such Fund investments. Each Fund is a limited partnership, comprising limited partner investors (each, an “Investor”) and a general partner. The activities of each Fund are governed by a limited partnership agreement (a “Partnership Agreement”) that specifies the investment guidelines and investment restrictions applicable to such Fund. Individual Investors enter into a subscription agreement under which the Investor agrees to be bound by the terms of the Fund’s Partnership Agreement and the subscription agreement (the 1 The Firm was initially organized as TC Growth Management, LLC and formally changed its name on April 12, 2016. Partnership Agreement and subscription agreements being referred to collectively as the “Governing Documents”). Each Fund is managed by one of the Firm’s Advisory Affiliates, as General Partner of such Fund. Each Advisory Affiliate, in turn, has entered into a management agreement with Sunstone Partners Management, LLC under which Sunstone Partners Management, LLC provides services associated with advising and managing the respective Fund. Each Advisory Affiliate retains investment and management authority over the business and affairs of the Fund for which it serves as General Partner, but delegates certain management and advisory services to the Firm. Sunstone Partners has offered co-investment opportunities (directly and indirectly) to existing investors, and expects to offer co-investment opportunities (directly and indirectly) to investors, Portfolio Operations Group members, portfolio company management or personnel, Sunstone Partners personnel, other certain persons associated with Sunstone Partners and/or other outside parties in the future. Such co-investments typically involve investment and disposal of interests in the applicable portfolio company of a Fund (a “Portfolio Company”) at the same time and on the same terms as the Fund making the investment. However, for strategic and other reasons, a co-investor or co-invest vehicle is permitted to purchase a portion of an investment from one or more Funds after such Funds have consummated their investment in the Portfolio Company (also known as a post-closing sell-down or transfer). There is no guarantee to any Investor that such Investor will be offered co-investment opportunities. The Firm will make all decisions regarding whether, to whom, and to what extent to offer co-investment opportunities in our sole discretion, subject to any restrictions contained in the Governing Documents of the relevant Fund. In some cases, a co-investment vehicle will be formed to invest in Portfolio Companies alongside one or more Funds in connection with the consummation of a transaction, subject to Sunstone Partners’ related policies and the relevant Partnership Agreement and/or side letter(s). Where a co-investment vehicle is formed, such entity often will bear expenses related to its formation and operation, many of which are similar in nature to those borne by the Funds. In the event that a transaction in which a co-investment was planned (including

a transaction for which a co-investment was believed necessary in order to consummate such transaction or for which a co-investment would otherwise be beneficial, in the judgment of the applicable General Partner) is not ultimately consummated, no co-investment vehicle generally will have been formed, and all unconsummated transaction expenses relating to such unconsummated transaction will be borne by the Fund or Funds selected by the applicable General Partner as proposed investors for such proposed transaction, and not by any prospective co-investors that were to have participated in such transaction, to the extent set forth in the applicable Partnership Agreement. However, to the extent that such co-investors have already invested in a co-investment or other vehicle in connection with such transaction, such co-investor or vehicle will in most cases bear its share of such unconsummated transaction expenses. C. Fund Investment Objectives and Restrictions Sunstone Partners generally has broad and flexible investment authority with respect to the Funds. Each Fund’s investment objective and strategy is set forth in the respective Fund’s Governing Documents. Investors are urged to carefully review a Fund’s Governing Documents prior to making an investment in a Fund. Sunstone Partners’ investment advice and investment authority is tailored and limited to that which is permitted under each Fund’s Governing Documents. The Firm does not provide investment advice directly to Investors in the Funds, and Investors in a Fund are bound by the investment strategy of that particular Fund, as described in such Fund’s Governing Documents. Sunstone Partners tailors its investment advice to each Fund and makes investment decisions in accordance with the Fund’s investment objectives, strategy and restrictions as set forth in such Fund’s Partnership Agreement. While certain individual Investors have separate legal rights under side letter agreements, as described in the next paragraph, the Firm does not tailor its advisory services to the individual needs of individual Fund Investors. Since the Firm does not provide individualized advice to Investors (and an investment in a Fund does not, in and of itself, create an advisory relationship between Sunstone Partners and the Investor), Investors must consider whether a particular Fund meets their investment objectives and risk tolerance prior to investing. Sunstone Partners and/or its affiliates reserve the right to enter into Side Letters with certain investors in a Fund providing such investors with different or preferential rights or terms, including, but not limited to, different fee structures or arrangements (including discounted or rebated compensation terms, modified waterfall mechanics and/or receipt of a portion of Sunstone Partners’ compensation), information rights, specialized reporting, priority co-investment rights or targeted co-investment amounts, rights to serve on the Fund’s Advisory Board, liquidity or transfer rights, confidentiality protections and disclosure rights, modification of default remedies, as well as economic, procedural and other terms, many of which will not be subject to the “most-favored nation” provisions of a Fund’s Governing Documents. Sunstone Partners is likely to have its own economic and/or other business incentives to provide certain terms to certain Investors, e.g., based on commitment amount to a Fund or the timing thereof, the ability of an Investor to provide sourcing or other services to Sunstone Partners, its affiliates and personnel or the Funds, or the potential to establish, recognize, strengthen or cultivate relationships that have the potential to provide longer-term benefits to Sunstone Partners, its affiliates and personnel, or the Funds. Further, Side Letters also are expected to relate to strategic relationships under which an Investor agrees to make Commitments to multiple Funds. Except in the circumstances and on the timing required by Governing Documents and/or applicable law, other Investors will not receive copies of Side Letters or related provisions, and as a general matter, the other investors have no recourse against a Fund, Sunstone Partners, the relevant General Partner or any of their affiliates in the event that certain investors have received additional and/or different rights and/or terms as a result of such Side Letters. Side Letters subject Sunstone Partners to potential conflicts of interest, including in circumstances where an Investor’s right to serve on the relevant Fund’s Advisory Board results in the Investor receiving additional information relative to other investors. To the extent an investor is subject to statutory or other limitations on indemnification, or otherwise negotiates rights relating thereto, other investors may be subject to increased losses, or be required to bear an increased portion of indemnification amounts. Other Side Letter rights are likely to confer benefits on the relevant Investor at the expense of the relevant Fund or of Investors as a whole, including in the event that a Side Letter confers additional reporting, information rights and/or transfer rights, the costs and expenses of which are expected to be borne by the relevant Fund. D. Wrap Fee Programs Sunstone Partners does not participate in wrap fee programs. E. Assets Under Management As of December 31, 2023, Sunstone Partners had a total of approximately $2,155,315,048 in regulatory assets under management, on a discretionary basis. The Firm does not currently manage any client assets on a non-discretionary basis.
