Secon 1. Compuaon of Indvdual Commody Performance Seres ( CPS ) and Percen Reurn Seres ( PR ) For each commody, a performance seres ( Commody Performance Seres ) s calculaed. These performance seres are hen used o calculae he Thomson Reuers/CoreCommody CRB Index. The CPS a me = 0 s scaled o equal 100 whle for any me he CPS s gven by: F F B B W 1, P, W 1, P, CPS, CPS 1,, > 0 F F B B W 1, P 1, W 1, P 1, for = 1 o 19 where: CPS, Commody Performance Seres for W W h commody a me.

B P, Prce of N.B.: hefron Monh FuuresConrac for Commody a me. heback Monh FuuresConrac for Commody a me. 1) The performance seres for each commody reflecs a consan dollar nvesmen such ha he rollng of he fuures conracs requres neher he addon nor whdrawal of funds. 2) The Fron Monh, or he Acve Conrac, s he monh closer o expraon; he Back Monh becomes he Fron Monh when he Back Monh wegh reaches 100%. 3) All values hroughou hs documen are rounded o sx decmal places. 4) All commody conracs roll over he frs four Busness Days of he monh such ha he wegh n he Fron Monh a he end of he frs rollover day s 75% and he wegh n he Back Monh s 25%. The wegh shfs from he Fron Monh o he Back Monh by 25% per rollover day unl he Back Monh reaches 100% a he end of he fourh Busness Day. (See Secon 4 for nformaon regardng rollover dsrupon evens.) The CPS are hen used o consruc he Percen Reurn Seres ( PR ) for each commody. 2

Secon 2. Compuaon of he Thomson Reuers/CoreCommody CRB Index The Thomson Reuers/CoreCommody CRB Index, s he Thomson Reuers/CoreCommody CRB Index a me, whch s smply he sum of all he PR, vz., Thomson Reuers/CoreCommody CRB Index 19 PR A he close of busness on June 17, 2005, he value of he Thomson Reuers/CoreCommody CRB Index, he Thomson Reuers/CoreCommody CRB Toal Reurn Index and each PR was as follows: Thomson Reuers/CoreCommody CRB Index 310.982965 Thomson Reuers/CoreCommody CRB Toal Reurn Index 272.908736 WTI Crude Ol 74.947877 Unleaded Gas (now RBOB Gasolne) 16.239293 Heang Ol 15.775786 Naural Gas 19.613922 Corn 18.816349 Soybeans 19.456962 Lve Cale 17.079943 Gold 18.349545 Alumnum 18.247679 Copper 18.594517 Sugar 15.075189 Coon 14.953757 Cocoa 15.743277 Coffee 13.179630 Nckel 3.031574 Whea 3.086284 Lean Hogs 2.824855 Orange Juce 3.055826 Slver 2.910700 1, 3

Subsequen values of each PR are compued as follows: PR PR CPS CPS,, 1,, / 1 A he end of he sxh Busness Day 1 of each monh, he Thomson Reuers/CoreCommody CRB Index s rebalanced and he PR for each commody s rescaled such ha: PR W Thomson Reuers/CoreCommody CRB Index for = 1 o 19 where: W Index wegh of commody, such ha 0 W 1, and and he value of each PR a he end of he sevenh Busness Day s equal o: PR r, Thomson Reuers/CoreCommody CRB Index r1 W CPS r, / where r s defned as he sevenh Busness Day of he monh.

Secon 4. Marke Dsrupon Provsons Rollover Dsrupons A Rollover Dsrupon Even ( RDE ) s defned as any day, on whch a commody s scheduled o roll, n whch eher: 1) he fron monh or back monh conracs for he commody sele a he daly maxmum or mnmum prce as deermned by he rules for he relevan exchange, or 2) he exchange fals o publsh an offcal selemen prce for he commody, or 3) he exchange on whch he commody rades s no scheduled o be open. If a RDE occurs for any commody, ha poron of he rollover for ha commody only whch was scheduled o occur on ha day wll be deferred unl he nex Busness Day upon whch no RDE occurs for ha commody. For example, f a RDE occurred on he frs day upon whch corn was scheduled o roll, hen he amoun o be rolled on he second day would ncrease o 50%. If a second and hrd consecuve RDE occurred on he nex wo days upon whch corn was scheduled o roll hen he enre roll would ake place a he end of he frs Busness Day n whch here was no RDE. These hypohecal rollover dsrupons n corn would have no mpac on he rollover schedule for oher commodes n he Thomson Reuers/CoreCommody CRB Index. Rebalancng Dsrupons If, on any dae he Thomson Reuers/CoreCommody CRB Index s scheduled o rebalance (defned above as he 6 h Busness Day of each monh), an offcal selemen prce for any one or more of he commodes n he Thomson Reuers/CoreCommody CRB Index s unavalable, hen he prce used n rebalancng he Thomson Reuers/CoreCommody CRB Index for hose commodes wll be he prce on he prevous Busness Day upon whch a prce s avalable. In he even any one or more ndvdual commodes sele a he daly maxmum prce or he daly mnmum prce, ha prce wll be used for he purpose of rebalancng he Index. Marke Emergences A Marke Emergency s heren defned as any unscheduled and exraordnary condon n whch marke lqudy s nerruped (such as an even resulng n he unscheduled closng of one or more fuures exchanges). Should a Marke Emergency occur, he Thomson Reuers/CoreCommody CRB Index Oversgh Commee reserves he rgh o ake such acon wh respec o he Thomson Reuers/CoreCommody CRB Index, as deems approprae gven he crcumsances. The Thomson Reuers/CoreCommody CRB Index Oversgh Commee wll aemp o nofy neresed pares of any such acons as well n advance as s praccable. There s no assurance, however, ha a Marke Emergency, he acons aken n response o such Marke Emergency, or any oher force majeure even, wll no have an adverse effec on he value of he Thomson Reuers/CoreCommody CRB Index or he manner n whch s calculaed. 6

Secon 5. Ongong Index Calculaon and he Thomson Reuers/CoreCommody CRB Index Oversgh Commee The role of he Thomson Reuers/CoreCommody CRB Index Oversgh Commee (he Commee ) s o mee on an annual bass (and from me o me f necessary) n order o revew and/or modfy he operaon and calculaon of he Thomson Reuers/CoreCommody CRB Index and procedures relang hereo, and o revew proposals by CoreCommody or Thomson Reuers o modfy he Thomson Reuers/CoreCommody CRB Index. The Commee wll be comprsed of 4 persons, apponed by CoreCommody and Thomson Reuers. Commee members wll be chosen n order o brng experse from a wde varey of backgrounds. Modfcaons o he Thomson Reuers/CoreCommody CRB Index shall be subjec o approval by he Commee. The Commee wll have a sgnfcan degree of dscreon wh regard o he operaon and calculaon of he Thomson Reuers/CoreCommody CRB Index and may exercse s dscreon, as deems approprae. 7
