Xxxxx Xxxxxxxx MLP Investment Company, a Maryland corporation (the “Company,” which term includes any successor corporation under the Indenture (as defined on the reverse hereof)), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of One Hundred Seventy-Five Million Dollars ($175,000,000) at the Stated Maturity shown above, and to pay interest thereon from the Original Issue Date shown above, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, quarterly on each Interest Payment Date as specified above, commencing on September 19, 2013, and at the Stated Maturity, at the Adjusted LIBOR Rate determined in accordance with the provisions specified below until the principal hereof is paid or made available for payment and at the Default Rate on any overdue principal (including any overdue required or optional prepayment of principal), any LIBOR Breakage Amount, any premium, and (to the extent legally enforceable) any overdue installment of interest.  The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Holder of this Note (this “Note”) as his, her or its name appears on the Security Register on the Regular Record Date as specified above next preceding such Interest Payment Date.  Except as otherwise provided in the Indenture, any interest in arrears for any past Interest Period may be paid at any time, without reference to any regular Interest Payment Date, to the Holder of this Note as his, her or its name appears on the Security Register on such date, not exceeding fifteen (15) days preceding the payment date thereof, as may be fixed by the Company.

The Series HH Notes (as defined on the reverse hereof) will bear interest for each Interest Period at a per annum rate determined by the Calculation Agent.  The interest rate applicable during each Interest Period will be the Adjusted LIBOR Rate, which will be equal to LIBOR for such Interest Period plus 1.25%.  On or promptly after the second London Business Day preceding each Interest Period (which, in the case of the first Interest Period, shall be on or promptly after the third London Business Day before the Original Issue Date as specified above), notice of the applicable Adjusted LIBOR Rate for such Interest Period shall be given by the Calculation Agent to the Holders of the Series HH Notes and the Company.  The Calculation Agent’s determination of the Adjusted LIBOR Rate shall be conclusive, absent manifest error.  In addition to all other amounts due and payable under the Indenture and under the Series HH Notes, the Adjusted LIBOR Rate applicable to each Series HH Note shall be increased by an amount equal to 1.00% per annum during any Adjustment Period.

Concurrent with the execution of this Note, the Company has entered into a Registration Rights Agreement (the “Registration Rights Agreement”).  Pursuant to and subject to the provisions of the Registration Rights Agreement, if (a) an offer of the Company to issue and deliver to the Holders of the Series HH Notes that are not prohibited by any law or policy of the Commission from participating in such offer, in exchange for the Series HH Notes, a like aggregate principal amount of floating rate senior notes identical in all material respects to the Series HH Notes, except for references to restrictive legends and references to the Registration Rights Agreement (the “Exchange Notes”), has not been consummated within 240 days after the Original Issue Date, or (b) after either the exchange offer registration statement covering the Exchange Notes or the shelf registration statement covering the resale of the Series HH Notes (the “Resale Notes”) has been declared effective, such registration statement thereafter ceases to be effective or usable in connection with resales of Exchange Notes or the Resale Notes, in accordance with and during the periods specified in the Registration Rights Agreement (each such event referred to in clauses (a) and (b), a “Registration Default”), then, as liquidated damages, interest (“Special Interest”) will accrue on the principal amount of the Series HH Notes (in addition to the stated interest on the Series HH Notes) from and including the date on which any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured.  Special Interest will accrue at a rate of 0.25% per annum with respect to the first 90-day period immediately following the occurrence of the first Registration Default and will increase to 0.50% per annum with respect to each subsequent 90 day period thereafter until all Registration Defaults have been cured; provided, however, that for the avoidance of doubt, such Special Interest shall not accrue during any subsequent 90 day period at a rate in excess of 0.50% per annum.  The Company shall pay Special Interest on regular interest payment dates in the same manner and to the same Persons as other interest.  Prior to determining a Registration Default relating to clause (b) of this paragraph, the Company’s right, pursuant to the Registration Rights Agreement, to defer the filing of any registration statement covering the Exchange Notes or Resale Notes (or suspend sales under any registration statement or defer the updating of any such registration statement and suspend sales thereunder) for a period of not more than 60 consecutive days (and, in the aggregate, not more than 90 days per any one calendar year period) if it determines that it would be materially detrimental to the Company to file such registration statement and concludes, as a result, that it is in the Company’s best interests and the best interests of its stockholders to defer the filing of such registration statement or suspend such sales at such time, shall be taken into account.  The Series HH Notes and any Exchange Notes shall be treated as a single class for all purposes under the Indenture, and unless

the context otherwise requires, all references to the Series HH Notes shall include any Exchange Notes.  The Company shall give the Trustee prompt written notice of the occurrence and cure of a Registration Default.

“Adjustment Period” means, with respect to any calculation of the applicable interest rate in respect of the Series HH Notes, any period of time during which any Series HH Note has a current rating of less than “A-” by Fitch Ratings or less than its equivalent by any other nationally recognized statistical ratings organization.

“Business Day” means any day other than a Saturday or a Sunday or a day on which banking institutions in New York City are authorized or required by law or executive order to remain closed or a day on which the Corporate Trust Office of the Trustee is closed for business.

“Calculation Agent” means an agent appointed by the Company to calculate LIBOR for purposes of the Indenture, which shall initially be the Trustee.

“Interest Period” or “Series HH Interest Period” means each period commencing on the Original Issue Date and, thereafter, commencing on an Interest Payment Date and continuing up to, but not including, the next Interest Payment Date.

“LIBOR” means, for any Series HH Interest Period, the rate per annum (rounded upwards, if necessary, to the next higher one hundred thousandth of a percentage point) for deposits in U.S. dollars for a three-month period which appears on the Bloomberg Financial Markets Service Page BBAM 1 (or if such page is not available, the Reuters Screen LIBO Page) as of 11:00 a.m. (London, England time) on the date two (2) London Business Days before the commencement of such Series HH Interest Period (or three (3) London Business Days prior to the beginning of the first Series HH Interest Period).  “Reuters Screen LIBO Page” means the display designated as the “LIBO” page on the Reuters Monitor Money Rates Service (or such other page as may replace the LIBO page on that service or such other service as may be nominated by the British Bankers’ Association as the information vendor for the purpose of displaying British Bankers’ Association Interest Settlement Rates for U.S. Dollar deposits).  If such rate does not appear on the Bloomberg Financial Markets Service Page BBAM 1 (or if such page is not available, the Reuters Screen LIBO Page) as of 11:00 a.m. (London, England time) on the date two (2) London Business Days before the commencement of such Series HH Interest Period (or three (3) London Business Days prior to the beginning of the first Series HH Interest Period), LIBOR will be determined on the basis of the rates at which deposits in U.S. dollars for such Series HH Interest Period and in a principal amount of not less than $1,000,000 are offered to prime banks in the London interbank market by four major banks in the London interbank market (which may include affiliates of the initial purchaser of the Series HH Notes) selected by the Calculation Agent (as directed by the Issuer), at approximately 11:00 a.m., London time, on the day on which interest is determined for that Series HH Interest Period.  The Calculation Agent will request the principal London office of each such bank to provide a quotation of its rate.  If at least two such quotations are provided, LIBOR with respect to that Series HH Interest Period will be the arithmetic mean of such quotations.  If fewer than two quotations are provided, LIBOR with respect to that Series HH Interest Period will be the arithmetic mean of the rates quoted by three major banks in New York City (which may include affiliates of the initial purchaser of the Series HH Notes) selected by the Calculation Agent (as directed by the Issuer), at approximately 11:00 a.m., New York City time, on the day on which interest is determined for that Series HH Interest Period for loans in U.S. dollars to leading European banks

for that Series HH Interest Period and in a principal amount of not less than $1,000,000. However, if fewer than three banks selected by the Calculation Agent to provide quotations are quoting as described above, LIBOR for that Series HH Interest Period will be the same as LIBOR as determined for the previous Series HH Interest Period.

“London Business Day” means a day that is a Business Day and a day on which dealings in deposits in U.S. dollars are transacted, or with respect to any future date are expected to be transacted, in the London interbank market.

Any interest payment made on the Series HH Notes shall first be credited against the earliest accrued but unpaid interest due with respect to such Series HH Notes.  Interest on the Series HH Notes shall be computed for the actual number of days elapsed on the basis of a year consisting of 360 days.

Payment of the principal of and interest due at the Stated Maturity or earlier prepayment of the Series HH Notes shall be made upon surrender of the Series HH Notes at the Corporate Trust Office of the Trustee.  The principal of, premium, if any, and interest on the Series HH Notes shall be paid in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.  Payment of interest (including interest on an Interest Payment Date) will be made, subject to such surrender where applicable, at the option of the Company, (i) by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or (ii) by wire transfer or other electronic transfer at such place and to such account at a banking institution in the United States as may be designated in writing to the Trustee at least 16 days prior to the date for payment by the Person entitled thereto. Notwithstanding the foregoing, as long as the Series HH Notes are represented by one or more Global Notes, payments with respect to such Global Notes shall be made in accordance with the customary procedures of the Depositary.

REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS NOTE SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

Unless the certificate of authentication hereon has been executed by the Trustee by manual signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed as of the date hereof.
