 Senior Unsecured Floating Rate Toggle Note due 2012 
 1. Interest 
 (a) US Oncology Holdings, Inc., a
Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security semi-annually on
March 15 and September 15 of each year, commencing September 15, 2007. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from March 13, 2007. The
amount of interest for each day that the Security is outstanding (the “Daily Interest Amount”) will be calculated by dividing the interest rate in effect for such day by 365 and multiplying the result by the principal amount of the
Security. The amount of interest to be paid on the Security for each Interest Period will be calculated by adding the Daily Interest Amounts for each day in the Interest Period. The Company shall pay interest on overdue principal at the rate borne
by the Securities plus 1% per annum, and it shall pay interest on overdue installments of interest at the rate borne by the Securities to the extent lawful. 
 The Company, may, at its option, elect to pay interest on this Security (i) entirely in cash (“Cash Interest”), (ii) entirely by increasing the principal amount of this Security (“PIK
Interest”) or (iii) 50% as Cash Interest and 50% as PIK Interest. PIK Interest will be payable by increasing the principal amount of the outstanding Security by an amount equal to the amount of PIK Interest for the applicable interest
period (a “PIK Payment”). To elect the form of interest payment with respect to each interest period, the Company shall give the Trustee irrevocable notice of such election not less than 5 days prior to the beginning of the related
interest period. The Trustee shall promptly deliver a corresponding notice to the Holders. In the absence of such an election for any interest period, interest on this Security will be payable entirely in the form of PIK Interest on the related
interest payment date. Interest for the first interest period commencing on the Issue Date shall be payable entirely in cash. 
 Cash
Interest will accrue on this Security at a rate per annum equal to LIBOR plus the Applicable Spread (the “Cash Interest Rate”) as determined by the calculation agent appointed by the Company (the “Calculation Agent”), which shall
initially be the Trustee. PIK Interest will accrue on this Security at a rate per annum equal to the Cash Interest Rate plus 75 basis points. LIBOR will be reset semiannually. The Applicable Spread will be 450 basis points from (and including) the
Issue Date to (but excluding) March 15, 2009 (the “Initial Step-Up Date”), increasing by 50 basis points from (and including) the Initial Step-Up Date to (but excluding) March 15, 2010, and increasing by another 50 basis points
thereafter. 
 If the Company elects to pay 50% as Cash Interest and 50% as PIK Interest, such Cash Interest and PIK Interest will be paid to
Holders on a pro rata basis. Following an increase in the principal amount of the outstanding Security as a result of a PIK Payment, this Security will accrue interest on such increased principal amount from and after the related interest payment
date of such PIK Payment. In connection with the payment of PIK Interest, the Company is entitled, without the consent of the Holders, to increase the outstanding principal amount of this Security. References herein to the “principal
amount” of this Security include any increase in the principal amount of the outstanding Security as a result of a PIK Payment. 
  

 5 







 All percentages resulting from any calculations in connection with the determination of interest on the
Securities will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point being rounded upwards (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)) and
all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards). The interest rate on the Security will in no event be higher than the maximum rate permitted by New York
law as the same may be modified by United States law of general application. 
 The Calculation Agent will, upon the request of the Holder of
any Security, provide the interest rate then in effect with respect to the Security. All calculations made by the Calculation Agent in the absence of manifest error will be conclusive for all purposes and binding on the Company and the Holders of
the Securities. 
 (b) Special Interest. The holder of this Security is entitled to the benefits of a Registration Rights Agreement,
dated as of March 1, 2007, among the Company and the Purchasers named therein (the “Registration Agreement”). Capitalized terms used in this paragraph (b) but not defined herein have the meanings assigned to them in the
Registration Agreement. In the event that (i) neither the Exchange Offer Registration Statement nor the Shelf Registration Statement has been filed with the Commission on or prior to the 120th day following the date of the original issuance of
the Securities, (ii) neither the Exchange Offer Registration Statement nor the Shelf Registration Statement has been declared effective on or prior to the 210th day following the date of the original issuance of the Securities,
(iii) neither the Registered Exchange Offer has been consummated nor the Shelf Registration Statement has been declared effective on or prior to the 240th day following the date of the original issuance of the Securities, or (iv) after the
Exchange Offer Registration Statement or the Shelf Registration Statement has been declared effective, such Registration Statement thereafter ceases to be effective or usable in connection with resales of the Securities at any time that the Company
is obligated to maintain the effectiveness thereof pursuant to the Registration Agreement (each such event referred to in clauses (i) through (iv) above being referred to herein as a “Registration Default”), interest (the
“Special Interest”) shall accrue (in addition to stated interest on the Securities) from and including the date on which the first such Registration Default shall occur to but excluding the date on which all Registration Defaults have been
cured, at a rate per annum equal to 0.25% of the principal amount of the Securities; provided, however, that such rate per annum shall increase by 0.25% per annum from and including the 91st day after the first such Registration
Default (and each successive 91st day thereafter) unless and until all Registration Defaults have been cured; provided further, however, that in no event shall the Special Interest accrue at a rate in excess of 1.00% per annum.
The Special Interest will be payable in cash semiannually in arrears each March 15 and September 15. 
 2. Method of Payment 
 The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of
business on the March 1 or September 1 next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to
collect principal payments. The Company will pay principal and interest in 

  

 6 







 
money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the
Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company will make all payments in
respect of a Definitive Security (including principal, premium and interest), by mailing a check to the registered address of each Holder thereof; provided, however, that payments on the Securities will be made by wire transfer to a
U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days
immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion). 
 3. Paying Agent and
Registrar 
 Initially, LaSalle Bank National Association, a national banking association (the “Trustee”), will act as Paying
Agent and Registrar. The Company may appoint and change any Paying Agent or Registrar without notice. The Company or any of its domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent or Registrar. 
 4. Indenture 
 The Company issued the Securities under
an Indenture dated as of March 13, 2007 (the “Indenture”), between the Company and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture
Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “TIA”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are
subject to all such terms, and Securityholders are referred to the Indenture and the TIA for a statement of those terms. 
 The Securities
are senior unsecured obligations of the Company. This Security is one of the Offered Securities referred to in the Indenture issued in an aggregate initial principal amount of $425,000,000. The Securities include the Offered Securities, an unlimited
amount of additional Initial Securities that may be issued under the Indenture, and any Exchange Securities issued in exchange for Initial Securities. The Offered Securities, such additional Initial Securities and the Exchange Securities are treated
as a single class of securities under the Indenture. The Indenture imposes certain limitations on the ability of the Company and its Restricted Subsidiaries to, among other things, make certain Investments and other Restricted Payments, pay
dividends and other distributions, incur Debt, enter into consensual restrictions upon the payment of certain dividends and distributions by such Restricted Subsidiaries, issue or sell shares of capital stock of such Restricted Subsidiaries, enter
into or permit certain transactions with Affiliates, create or incur Liens, enter into or permit certain Sale and Leaseback Transactions and make Asset Sales. The Indenture also imposes limitations on the ability of the Company to consolidate or
merge with or into any other Person or sell, transfer, assign, lease, convey or otherwise dispose of all or substantially all of the Property of the Company. 
 5. Optional Redemption 
 Except as set forth below, the Securities may not be redeemed at the option of the Company prior to
September 15, 2007. Starting on that date, the Company may redeem all or 

  

 7 







 
any portion of the Securities at once or over time, after giving the required notice under the Indenture. The Securities may be redeemed at the redemption
prices set forth below, plus accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date). The following prices are
for Securities redeemed during the 12-month period commencing on March 15 of the years set forth below, and are expressed as percentages of principal amount: 
  

			
	 Redemption Period
	  	Price
	On or after September 15, 2007 and prior to September 15, 2008	  	100.00%
	On or after September 15, 2008 and prior to September 15, 2009	  	102.00%
	On or after September 15, 2009 and prior to September 15, 2010	  	101.00%
	On or after September 15, 2010	  	100.00%

 Notwithstanding the foregoing, at any time and from time to time, prior to March 15, 2009,
the Company may redeem up to a maximum of 35% of the original aggregate principal amount of the Securities (which includes any additional Securities) with the proceeds from one or more Qualified Equity Offerings (provided that, if the Qualified
Equity Offering is an offering by any Parent, a portion of the net cash proceeds thereof equal to the amount required to redeem any such Securities is contributed to the equity capital of the Company or used to acquire Capital Stock of the Company
(other than Disqualified Stock) from the Company), at a redemption price equal to 100% of the aggregate principal amount so redeemed plus a premium equal to the interest rate per annum of the Securities applicable on the date on which the notice of
redemption is given thereof, plus accrued and unpaid interest thereon, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date);
provided, however, that after giving effect to any such redemption, at least 65% of the original aggregate principal amount of the Securities remains outstanding. Any such redemption shall be made within 90 days of such Qualified
Equity Offering. 
 The Company may choose to redeem all or any portion of the Securities, at once or over time, prior to September 15,
2007. If it does so, it may redeem the Securities, after giving the required notice under the Indenture. To redeem the Securities, the Company must pay a redemption price equal to the sum of: 
 (a) 100% of the principal amount of the Securities to be redeemed, plus 
 (b) the Applicable Premium, 
 plus accrued and unpaid interest, if any, to the redemption date (subject to
the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date). 
 “Applicable Premium” means, with respect to any Security at any time, the greater of (1) 1.0% of the principal amount of such Security at such time and (2) the excess of (A) the present value at such time of
(i) the redemption price of such Security at September 15, 

  

 8 







 
2007 (such redemption price being described in the table appearing in the first paragraph of this Paragraph (5) exclusive of any accrued interest) plus
(ii) any required interest payments due on such Security through September 15, 2007 (including any accrued and unpaid interest), such interest payments to be determined in accordance with the Indenture assuming that LIBOR in effect on the
date of such redemption notice would be the applicable LIBOR in effect through September 15, 2007, computed using a discount rate equal to the Treasury Rate plus 50 basis points, over (B) the principal amount of such Security. 

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a
maturity comparable to the remaining term of the Securities that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the
remaining term of such Securities. “Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Trustee after consultation with the Company. 
 “Comparable Treasury Price” means, with respect to any redemption date: 
 (a) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal
amount) on the third business day preceding such redemption date, as set forth in the most recently published statistical release designated “H.15(519)” (or any successor release) published by the Board of Governors of the Federal Reserve
System and which establishes yields on actively traded United States treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities” or 
 (b) if such release (or any successor release) is not published or does not contain such prices on such business day, the average of the
Reference Treasury Dealer Quotations for such redemption date. 
 “Reference Treasury Dealer” means Citigroup Global Markets
Inc., Morgan Stanley & Co. Incorporated and Wachovia Capital Markets, LLC and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in New
York City (a “Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer. 
 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the third business day preceding such redemption date. 
 “Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the yield to maturity of the Comparable Treasury
Issue, compounded semi-annually, assuming a price for such Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. 
  

 9 







 6. Notice of Optional Redemption 
 Notice of optional redemption will be mailed by first-class mail at least 30 days but not more than 60 days before the redemption date for an optional redemption to each Holder of Securities to be redeemed at his or
her registered address. Any notice to holders of Securities of such a redemption needs to include the appropriate calculation of the redemption price, but does not need to include the redemption price itself. The actual redemption price, calculated
as described above, must be set forth in an Officers’ Certificate delivered to the Trustee no later than two business days prior to the redemption date. Securities in denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000. If money sufficient to pay the optional redemption price of and accrued interest on all Securities (or portions thereof) to be redeemed on the redemption date for an optional redemption is deposited with the Paying Agent on or
before the redemption date for an optional redemption and certain other conditions are satisfied, on and after such date interest ceases to accrue on such Securities (or such portions thereof) called for redemption. 
 7. Sinking Fund 
 The Securities are not subject to
any sinking fund. 
 8. Repurchase of Securities at the Option of Holders upon Change of Control 
 Upon a Change of Control, any Holder of Securities will have the right, subject to certain conditions specified in the Indenture, to cause the Company to
repurchase all or any part of the Securities of such Holder at a purchase price equal to 101% of the principal amount of the Securities to be repurchased plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of
Holders of record on the relevant record date to receive interest due on the relevant interest payment date) as provided in, and subject to the terms of, the Indenture. 
 9. Denominations; Transfer; Exchange 
 The Securities are in registered form without coupons in
denominations of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. Upon any transfer or exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements or transfer documents and to pay any taxes required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case of a Security
to be redeemed in part, the portion of the Security not to be redeemed) or to transfer or exchange any Securities for a period of 15 days prior to a selection of Securities to be redeemed or 15 days before an interest payment date. 
 10. Persons Deemed Owners 
 The registered Holder of
this Security may be treated as the owner of it for all purposes. 
 11. Unclaimed Money 
 If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at
its written request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment. 
  

 10 







 12. Discharge and Defeasance 
 Subject to certain conditions, the Company at any time may terminate some of or all its obligations under the Securities and the Indenture if the Company deposits with the Trustee money or U.S. Government Obligations
for the payment of principal and interest on the Securities to redemption or maturity, as the case may be. 
 13. Amendment, Waiver 
 Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended without prior notice to any
Securityholder but with the written consent of the Holders of at least a majority in aggregate principal amount of the outstanding Securities and (ii) any default or noncompliance with any provision may be waived with the written consent of the
Holders of at least a majority in principal amount of the outstanding Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Holder of Securities, the Company and the Trustee may amend the Indenture or the
Securities to (i) cure any ambiguity, omission, defect or inconsistency; (ii) comply with Article V of the Indenture; (iii) provide for uncertificated Securities in addition to or in place of certificated Securities;
provided, however, that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code or in a manner such that the uncertificated Securities are described in Section 163(f)(2)(B) of
the Code; (iv) add Guarantees with respect to the Securities or to release Subsidiary Guarantors from Subsidiary Guarantees as provided by the terms of the Indenture, (v) secure the Securities; (vi) add to the covenants of the Company
for the benefit of the Holders or to surrender any right or power herein conferred upon the Company; (vii) comply with any requirements of the SEC in connection with qualifying, or maintaining the qualification of, the Indenture under the TIA;
(viii) make any change that does not adversely affect the rights of any Securityholder; or (ix) provide for the issuance of additional Securities in accordance with the Indenture. 
 14. Defaults and Remedies 
 If an Event of Default
occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding, subject to certain limitations, may declare all the Securities to be immediately due and payable. Certain events
of bankruptcy or insolvency are Events of Default and shall result in the Securities being immediately due and payable upon the occurrence of such Events of Default without any further act of the Trustee or any Holder. 
 Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the
Indenture or the Securities unless it receives reasonable indemnity or security. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the Trustee in its exercise of any
trust or power under the Indenture. The Holders of a majority in aggregate principal amount of the Securities then outstanding, by written notice to the Company and the Trustee, may rescind any declaration of acceleration and its consequences if the
rescission would not conflict with any judgment or decree, and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of the acceleration. 
  

 11 







 15. Trustee Dealings with the Company 
 Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 
 16. No Recourse Against Others 
 A director, officer,
manager, employee, member, partner or stockholder, as such, of the Company or any Subsidiary Guarantor shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or
by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. 
 17. Authentication 
 This Security shall not be valid
until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Security. 
 18. Abbreviations 
 Customary abbreviations may be used in the name of a Securityholder or an assignee, such as TEN COM
(=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act). 
 19. Governing Law 
 THIS SECURITY SHALL BE GOVERNED
BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 20. CUSIP Numbers 
 Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be
printed on the Securities and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Securityholders. No representation is made as to the accuracy of such numbers either as printed on the Securities or as
contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 
 The Company
will furnish to any Holder of Securities upon written request and without charge to the Holder a copy of the Indenture which has in it the text of this Security.
