                United Nations Security Council, the European Union, the United Kingdom, or other relevant sanctions authority (collectively, “Sanctions”) and agrees that the investor will not directly or indirectly transfer funds into an account of the
                Fund that are derived from entities, persons or activities subject to Sanctions. The investor shall not use funds received from the Fund and/or its account for the benefit of and/or to transact with, directly or indirectly, any person,

              The investor waives any counterclaim to, and any right to any setoff or reduction of, its obligation to make capital contributions or other payments to the Fund based on any claim that it has against any person (without prejudice to the
                investor’s right to assert such claim in a separate action).

              The investor agrees to purchase Interests for an aggregate purchase price equal to its Capital Commitment, payable at such times and in such amounts as required by the Fund, under the terms and subject to the conditions set forth herein.

            	(ii)	
              Purchases of Interests will take place on dates selected by the Fund in its sole discretion (each, a “Capital Drawdown Date”) and shall be made in accordance with the provisions of this Section 2.b.

            


      

      

      	

            	(iii)	
              On each Capital Drawdown Date, the investor agrees to purchase from the Fund, and the Fund agrees to issue to the investor, a number of Interests equal to the Drawdown Share Amount (as defined below) at an aggregate price equal to the
                Drawdown Purchase Price (as defined below); provided, however, that in no circumstance will an investor be required to purchase Interests for an amount in excess of its Unused Capital Commitment (as defined below).

            


      

      

      “Drawdown Purchase Price” shall mean, for each Capital Drawdown Date, an amount in U.S. dollars determined by multiplying (i) the aggregate amount of Capital Commitments being drawn down by the
        Fund from all investors on that Capital Drawdown Date, by (ii) a fraction, the numerator of which is the Unused Capital Commitment of the investor and the denominator of which is the aggregate Unused Capital Commitments of all investors that are
        not Defaulting Investors or Excluded Investors (as defined below). For the avoidance of doubt, the Drawdown Purchase Price shall be determined after giving effect to the Catch-Up Purchase Price (as described below).

      

      

      “Drawdown Share Amount” shall mean, for each Capital Drawdown Date, a number of Common Shares determined by dividing (i) the Drawdown Purchase Price for that Capital Drawdown Date by (ii) the

      “Per Interest NAV” shall mean, for any Capital Drawdown Date or Catch-Up Date (as defined below), the net asset value per Interest, as determined as of the end of the most recent fiscal quarter for
        which net asset value has been determined prior to the Capital Drawdown Date (as defined below) in accordance with the valuation policies adopted by the Fund's board of directors (the “Board”).

      

      

      “Per Interest Price” shall mean, for any Capital Drawdown Date or Catch-Up Date (as defined below), the Per Interest NAV, subject to adjustment from the latest quarterly valuation date in
        accordance with the Fund’s valuation policy and subject to Section 23 of the Investment Company Act of 1940, as amended (the “1940 Act”) (which generally prohibits the Fund from issuing Interests at a price below the then-current net asset value of
        the Interests as determined within 48 hours, excluding Sundays and holidays, of such issuance).

                  purchase price of Interests to be sold to all investors on the Capital Drawdown Date, (iii) the applicable Drawdown Purchase Price and (iv) the account to which the Drawdown Purchase Price should be wired.

              


      

      

      

      	

            	(v)	
              The delivery of a Drawdown Notice to the investor shall be the sole and exclusive condition to the investor’s obligation to pay the Drawdown Purchase Price identified in each Drawdown Notice, and shall represent the Fund’s acceptance of
                the investor’s irrevocable and ongoing offer to purchase Interests.

            


      

      

      	

            	(vi)	
              On each Capital Drawdown Date, the investor shall pay the Drawdown Purchase Price to the Fund by bank wire transfer in immediately available funds in U.S. dollars to the account specified in the Drawdown Notice.

            


      

      

      	

            	(vii)

            	(A)	
              cover, or reserve, for actual or anticipated expenses and liabilities of the Fund (including payment of the base management fee and incentive compensation to the Investment Manager, operating expenses and indemnification or other
                obligations of the company, whether contingent or otherwise);

            


      

      

      	

            	(B)	
              complete investments that were approved by the Investment Manager’s investment committee for the Fund prior to the expiration of the Investment Period or as to which a definitive agreement, letter of intent, memorandum of understanding
                or similar document (whether or not legally binding on the parties thereto) has been entered into prior to the expiration of the Investment Period (each, a “Pending Investment”);

                (D)

                (E)

              	
                exercise any equity rights held as of the end of the Investment Period;

              


      

      

      

      	

            	(F)	
              fund any additional investment (in addition to any included in (B) and (C) above) that the Investment Manager determines in its discretion is appropriate or necessary to preserve or protect the value of any existing investment (each, a
                “Follow-On Investment”) in an amount equal to up to 15% of the aggregate Capital Commitments.

            


      

      

      For the avoidance of doubt, any investment that is in the nature of a revolving credit facility or line of credit, delayed draw loan or similar financing arrangement will be treated as a Pending
        Investment and not a Follow-On Investment for purposes of the foregoing limitations.

      

      

      	

            	(viii)	
              Notwithstanding anything to the contrary contained in this Supplement, the Master Subscription Agreement, the Memorandum or the Fund Agreement, the Fund shall have the right (a “Limited Exclusion Right”) to exclude any investor (such
                investor, an “Excluded Investor”) from purchasing Interests from the Fund on any Capital Drawdown date if, in the reasonable discretion of the Fund, there is a substantial likelihood that such investor’s purchase of Interests at such time
                would (i) result in a violation of, or noncompliance with, any law or regulation to which such investor, the Fund, the Investment Manager, any other investor or a portfolio company would be subject or (ii) cause the investments of “Benefit
                Plan Investors” (within the meaning of Section 3(42) of the U.S. Employee Retirement Income Security Act of 1974, as amended (“ERISA”) and certain Department of Labor regulations) to be significant and the assets of the Fund to be
                considered “plan assets” under ERISA or Section 4975 of the Code.

            


      

      

      	

            	c.	
              Subsequent Investors.

            


      

      

      	

            	(i)	
              The Fund expects to enter into separate subscription agreements with other investors (the “Other Investors,” and together with the Investor, the “Investors”), providing for the sale of Interests to the Other Investors. Other investors
                may subscribe for Shares at one or more closings after the Initial Closing (each, a “Subsequent Closing”). The Initial Closing and each Subsequent Closing are each referred to as a “Closing.” An Investor whose subscription is accepted at a
                Subsequent Closing (including any Investor that makes an additional capital commitment to purchase Interests on a date after its initial subscription has been accepted) is referred to herein as a “Subsequent Investor.”

            


      

      

      	

            	(ii)	
              Notwithstanding the provisions of Section 2.b, on one or more dates to be determined by the Fund that occur on or following the Subsequent Closing but no later than the next succeeding Capital Drawdown Date (each, a “Catch-Up Date”),
                each Subsequent Investor shall be required to purchase from the Fund, on no less than ten (10) calendar days’ prior notice, a number of Interests with an aggregate purchase price (the “Catch-Up Purchase Price”) necessary to ensure that,
                upon payment of the aggregate purchase price for such Interests by the Subsequent Investor in the aggregate for all Catch-Up Dates, such Subsequent Investor’s Net Contributed Capital Percentage (as defined below) shall be equal to the Net
                Contributed Capital Percentage of all prior Investors (other than any Defaulting Investors, Excluded Investors or any Other Investor who has subscribed on prior Subsequent Closings and have not yet funded the Catch-Up Purchase Price).

            


      

      

      	

            	(iii)	
              Upon payment of the Catch-Up Purchase Price by the Subsequent Investor on a Catch-Up Date, the Fund shall issue to such Subsequent Investor a number of Shares determined by dividing (x) the Catch-Up Purchase Price for such Subsequent
                Investor minus the Organizational Cost Allocation (as defined below) by (y) the Per Interest Price for such Subsequent Investor as of a Catch-Up Date. For the avoidance of doubt, in the event that the Catch-Up Date and a Capital Drawdown
                Date occur on the same calendar day, such Catch-Up Date (and the application of the provisions of this Section 2.c) shall be deemed to have occurred immediately prior to the relevant Capital Drawdown Date.

            


       

      

      
        5

        
          


      

      	

            	(iv)	
              As used in this Section 2.c:

            


       

      

      	

            	(A)	
              “Net Contributed Capital Percentage” means, with respect to an Investor, the percentage determined by dividing such Investor’s Net Contributed Capital (as defined below) by such Investor’s Capital Commitment.

            


      

      

      	

            	(B)	
              “Net Contributed Capital” means (i) the aggregate amount of capital contributions that have been made by an Investor in respect of its Shares, less (ii) the aggregate amount of distributions categorized as Returned Capital (as defined
                below) made by the Fund to such Investors in respect of its Shares. For the avoidance of doubt, Net Contributed Capital will not take into account distributions of the Fund’s investment income (i.e., proceeds received in respect of interest
                payments, dividends or fees, net of expenses) to Investors. Net Contributed Capital with respect to an Investor shall be calculated on the basis of such Investor’s capital contributions and distributions made to such Investor categorized as
                Returned Capital.

            


      

      

      	

            	(C)	
              “Returned Capital” shall mean any distribution, or any portion of distributions, made by the Fund to an investor during the Investment Period which is designated as such (regardless of tax character) and represents (A) proceeds realized
                from the sale or repayment of any investment (as opposed to investment income) during the Investment Period (but not in excess of the cost of any such investment) or (B) a return of such investor’s capital contributions to the Company.

            


      

      

      	

            	(D)	
              “Organizational Cost Allocation” means, with respect to an Investor, the product obtained by multiplying (x) a fraction, the numerator of which is such Investor’s Capital Commitment and the denominator of which is the total Capital
                Commitments received by the Fund to date by (y) the lesser of (a) a dollar amount equal to one million dollars ($1,000,000) and (b) the total amount of organizational expenses and offering costs incurred by the Fund in connection with its
                organization and offering.

            


      

      

      	

            	d.	
              Capital Drawdown Default.

            


      

      

      	

            	(i)	
               If an Investor fails to make full payment of any portion of the Drawdown Purchase Price due from such Investor on any Capital Drawdown Date or Catch-Up Purchase Price due from such Investor on any Catch-Up Date (such amount, together
                with the full amount of such Investor’s remaining Capital Commitment, a “Defaulted Commitment”), the Fund shall give such Investor written notice of its default in payment and in the event such default shall continue beyond the tenth
                calendar day following such notice, the Fund shall be permitted to declare such Investor to be in default of its obligations under this Supplement (any such Investor, a “Defaulting Investor”) and may, in its discretion, take any one or more
                of the following actions:

            


      

      

      	

            	(A)	
              The Fund may assist the Defaulting Investor in finding a buyer for the Defaulting Investors Capital Commitment that will assume the Defaulting Investor's obligations hereunder, subject to the restrictions on transfer contained in the
                Governing Documents (in which case such Person shall, as a condition of purchasing such Capital Commitment, become a party to this Supplement and assume such Defaulting Limited Investor's obligation to make both defaulted and future
                purchases.)

            


      

      

      	

            	(B)	
              The Fund may pursue and enforce all rights and remedies the Fund may have against the Defaulting Investor, including a lawsuit to collect the overdue amount and the costs (including attorneys' fees) and expenses of collecting such
                overdue amount, with interest calculated thereon commencing on the applicable Capital Drawdown Date at a variable rate per annum equal to the rate of interest published from time to time by The Wall Street Journal as the "prime rate" at
                large United States money center banks, plus eight percent (8%) per annum (but not in excess of the highest rate per annum permitted by applicable law). In addition, the costs of any interim financing obtained by the Fund due to the
                Defaulting Investor's failure to timely make its Drawdown Purchases shall be reimbursed to the Fund by the Defaulting Investor. Any such reimbursement shall be deemed not to constitute payment of a Drawdown Purchase Price or reduce the
                Investor’s Capital Commitment.

            


      

      

      	

            	(C)	
              The Fund may cause two-thirds of the Common Shares then held by the Defaulting Investor to be automatically transferred on the books of the Fund, without any further action being required on the part of the Defaulting Investor, to the
                other non-defaulting Investors, pro rata in accordance with their respective Capital Commitments. The mechanism described in this Section 2(d)(i)(C) is intended to operate as a liquidated damage provision, since the damage to the Company
                and Other Investors resulting from a default by the Defaulting Investor is both significant and not easily susceptible to precise quantification. By entry into this Supplement, the Investor agrees to this transfer and acknowledges that it
                constitutes a reasonable liquidated damage remedy for any default in the Investor’s obligation of the type described.

            


       

      

      
        6

        
          


      

      	

            	(D)	
              The Fund may offer to the Investors (other than such Defaulting Investor) for assumption by the non-defaulting Investors such Defaulting Investor’s Capital Commitment to make its Defaulted Commitment, which offer shall be made pro rata
                in accordance with the non-defaulting Investors' respective Interests. If a non-defaulting Investor elects not to assume the entire portion of the Defaulted Commitment offered to it, such unassumed Defaulted Commitment shall be reoffered
                pro rata to the non-defaulting Investors who have elected to assume the entire portion of the Defaulted Commitment offered to them until either all of such Defaulted Commitment is assumed or no non-defaulting Investor wishes to make a
                further assumption of the Defaulted Commitment. At the closing of such offer (on a date and at a place designated by the Fund), each assuming Investor shall make a payment in an amount equal to that portion of the Defaulted Commitment
                assumed by it in accordance with the provisions of this subparagraph which is then due or past due. The Manager shall specify the procedures for making and accepting the offers contemplated by this subparagraph and shall, in its discretion,
                set time limits for acceptance. If the entire Defaulted Commitment is not assumed pursuant to the preceding provisions, the Fund may offer to any other Person for assumption any remaining portion of the Defaulted Commitment. Such Defaulting
                Investor's Capital Commitment shall be reduced by the aggregate amount of Defaulted Commitment assumed by the non-defaulting Investors and such other Persons and for which payments have been actually received by the Fund.

            


      

      

      	

            	(E)	
              The Fund may reduce (effective on the date of the default) the Defaulting Investor's Unused Capital Commitment (to the extent it has not been assumed by another Investor or Person) to the amount of Capital Commitments actually received
                by the Fund from such Defaulting Investor (net of distributions), and the aggregate Capital Commitment of such Defaulting Investor shall be commensurately reduced; provided, however, that the Capital Commitments of the non-defaulting
                Investors shall not be reduced.

            


      

      

      	

            	(F)	
              If the Defaulting Investor is an entity formed for the purpose of investing in the Fund and such Defaulting Investor's failure to make any portion of a Drawdown Purchase when required is caused by the failure of one or more of such
                Defaulting Investor’s investors to either (i) make an equity contribution or (ii) deliver payment in exchange for any notes issued to such investor, to such Defaulting Investor, the Fund may, in its discretion, apply the provisions of this
                Section 2.d to such Defaulting Investor’s Interests and/or Capital Commitments on a pro rata basis to appropriately reflect the effect of the failure of such Defaulting Investor's defaulting equity investors in a manner which is equitable
                to such Defaulting Investor’s non-defaulting equity investors.

            


      

      

      	

            	(ii)	
              To the maximum extent permitted by applicable law, the Defaulting Investor hereby makes, constitutes and appoints the Fund with full power of substitution, its true and lawful proxy to exercise all voting and other rights of such
                Defaulting Investor with respect to Interests, at every annual, special or adjourned meeting of the shareholders of the Fund and in every written consent in lieu of such meeting in exact proportion to the votes or consents cast by Investors
                other than Defaulting Investors or, in the absence of any such Investors, in the discretion of the proxy.

            


      

      

      	

            	(iii)	
              Notwithstanding anything to the contrary contained in this Supplement, no Interests shall be offered or transferred to any other Investor pursuant to this Section 2.d in the event that such transfer would (x) violate the Securities Act
                of 1933, as amended (the “Securities Act”), the Investment Company Act or any state (or other jurisdiction) securities or “Blue Sky” laws applicable to the Fund or such transfer, (y) constitute a non-exempt “prohibited transaction” under
                Section 406 of ERISA or Section 4975 of the Code or (z) cause all or any portion of the assets of the Fund to constitute “plan assets” under ERISA or Section 4975 of the Code (it being understood that this proviso shall operate only to
                extent necessary to avoid the occurrence of the consequences contemplated herein and shall not prevent such Investor from receiving a partial allocation of its pro rata portion of transferred Interests of the Defaulting Investor).

            


      

      

      	

            	(iv)	
              No consent of any Investor shall be required as a condition precedent to any transfer, assignment, assumption or other disposition of a Defaulting Investor's Interests or Capital Commitment, as the case may be, pursuant to Section 2.d.
                If all of the Defaulting Investor's Interests and its Capital Commitments are transferred and/or purchased in the manner set forth in Section 2.d, such Defaulting Investor shall cease to be an Investor in the Fund and shall cease to have
                the power to exercise any rights or powers of an Investor.

            


      

      

      	

            	(v)	
              The Investor agrees that this Section 2.d is solely for the benefit of the Fund and shall be interpreted by the Fund against a Defaulting Investor in the discretion of the Fund. The Investor further agrees that the Investor cannot and
                will not seek to enforce this Section 2.d against the Fund or any other investor in the Fund.

         •          An investment in our shares
              is not suitable for you if you might need access to the money you invest in the foreseeable future. 

         •          You should not expect to be
              able to sell your shares regardless of how we perform. 

         •          Since you are unable to sell
              your shares, you will be unable to reduce your exposure on any market downturn. 

         •          We do not intend to list our
              shares on any securities exchange, and we do not expect a secondary market in the shares to develop. 

         •          Our distributions may be
              funded from unlimited amounts of offering proceeds or borrowings, which may constitute a return of capital and reduce the amount of capital available to us for investment. Any capital returned to you through distributions will be distributed
              after payment of fees and expenses. 

         •          We will invest in securities
              that are rated below investment grade by rating agencies or that would be rated below investment grade if they were rated. Below investment grade securities, which are often referred to as “junk,” have predominantly speculative
              characteristics with respect to the issuer’s capacity to pay interest or repay principal. They may also be difficult to value and illiquid. 

         •          Investing in our stock may be considered speculative and involves a high degree of risk, including the risk of a substantial loss of investment. See “Item 1A. Risk Factors” in the Company's registration
                statement to read about the risks you should consider before buying shares of our stock, including the risk of leverage.
