|  Floating      Rate Bills                    |  If      you ask, we agree to discount bills accepted by us under this facility at      a variable rate. Before doing so we agree with you on the term to maturity      of the bills. All bills are discounted once only for that maturity. We      discount bills at the SGB Rate, which is the rate we are prepared to buy      bills of an equivalent term to maturity and face value accepted by an      Australian trading bank on the day of acceptance. |
|  Fixed      Rate Bills                       |  If      you ask, we agree to discount bills accepted by us under this facility at      a fixed rate for an agreed term and aggregate face value. You may request      this in respect of the first drawing or at the completion of a term to      maturity (or expiry of a period in which the discount rate has been      previously fixed). We agree to discount bills for an additional period      provided the term does not end after the overall term of the      facility. |
|                                              |  You      may request us to give you an indicative quotation as to the discount rate      likely to apply (at any time). However, any indicative quotation given is      not binding on us. If we agree, you can also request us to fix a rate for      a specific term and aggregate face value, to apply at a future date      (called a “forward start      bill arrangement”). |

|                           |  Following      the end of any period in which the discount rate has been fixed, if you do      not ask us to fix it for a further period, the discount rate will be      calculated on a variable basis (see “Floating Rate Bills”      above).                                                                                                                                                                                                                                                                                                                          |

|  Capped      Rate Bills   |  If      you ask, we agree to discount bills accepted by us under this facility at      a capped rate for an agreed term and aggregate face value. You may request      this in respect of the first drawing or at the completion of a term to      maturity (or expiry of a period in which the discount rate has been      previously capped). We agree to discount bills for an additional period      provided the term does not end after the overall term of the      facility.                                                                                                 |
|                           |  We      discount Capped Bills at either the cap rate or the reference rate (the      reference rate we use is the rate set out in “Floating Rate Bills” above).      If, on the acceptance date of any bills during the agreed capped rate      term,                                                                                                                                                                                                                                                                                                                    |

If we agree, you can also request us to cap a rate for      a specific term and aggregate face value, to apply at a future date      (called a “forward start      bill arrangement”).                                                                                                                                                                                             |
|                           |  Following      the end of any period in which the discount rate has been capped, if you      do not ask us to cap it for a further period, the discount rate will be      calculated on a variable basis (see “Floating Rate Bills”      above).                                                                                                                                                                                                                                                                                                                         |
|  Collared      Rate Bills |  If      you ask, we agree to discount bills accepted by us under this facility at      a rate equal to or between a cap rate and a floor rate for an agreed term      and aggregate face value. These are known as Collared Rate Bills. You may      request this in respect of the first drawing or at the completion of a      term to maturity (or expiry of a period in which the discount rate has      been set for Collared Rate Bills). We agree to discount bills for an      additional period provided the term does not end after the overall term of the      facility. |
|                           |  We      discount Collared Rate Bills at either a cap rate, a floor rate or the      reference rate (the reference rate we use is the rate set out in “Floating      Rate Bills” above).                                                                                                                                                                                                                                                                                                                                                                                  |

It is calculated from and including the date we accept a bill      until but excluding the date of maturity of the bill. It is payable by you      on the day we accept a bill and is deducted from any discounted      proceeds                                                                                                                                                                                                                                                                 |

|  Premiums  |  A      premium is payable for entering into Capped Rate Bills and Collared Rate      Bills. Its amount and the date you must pay it is set out in the      confirmation we issue to you when we discount the Capped Rate Bill or the      Collared Rate Bill. (If the confirmation specifies more than one premium,      but does not specify which is payable on which premium payment date, the      first premium specified is payable on the first premium payment date      specified, and so on.)                       |
|            |  However,      a confirmation for Collared Rate Bills may specify a net premium to be      paid by the net premium payer. If the confirmation does this, then only      the net premium is payable on the net premium payment date set out in the      confirmation. (If the confirmation specifies more than one net premium,      but does not specify which is payable on which net premium payment date,      the first net premium specified is payable on the first net premium      payment date specified, and so on.) |
|  Indemnity |  You      must pay us an amount equal to the face value of each bill we accept under      this facility not later than 10.00 am on the day the bill falls due for      payment at the completion of the term to maturity. You also indemnify us      against, and therefore you must pay us on demand for, any other liability,      loss or costs we      incur or suffer in connection with our acceptance of bills under this      facility.                                                                                |
|            |  If      you elect not to rollover any bills discounted during a period in which      the discount rate has been fixed, (or if you and we enter into a forward start bill arrangement      and, for any reason, any bill is not drawn on the agreed future      date) you must, in addition to your indemnification obligations, pay us      any break costs      (see the “Break costs” clause in the General Standard      Terms).                                                                               |
|            |  If      you do not pay any amount you owe us when it is due (including any amount      payable under this “Indemnity”) you must pay interest on that overdue      amount at the default      rate. The “Default Interest” clause in the General Standard Terms      explains how we calculate default interest.                                                                                                                                                                                       |
|  Rollover  |  If      you are not in default we agree to rollover maturing bills, in which case      the procedures set out above apply equally. Unless you tell us otherwise      by close of the business      day before the relevant rollover date, we will rollover maturing      bills for bills of an equivalent face value and an equivalent term to      maturity or to the end of the term (whichever is      shorter).                                                                                                           |
