EXPLANATORY NOTE

The purpose of this Post-Effective Amendment No. 1 to US Oncology, Inc.’s Registration Statement on Form S-4/A is to include alternate pages to the complete prospectus relating to the exchange offer, which pages will be included in a separate prospectus relating solely to the market-making transactions in the exchange notes to be conducted by Morgan Stanley & Co. Incorporated. This separate prospectus is referred to herein as the “market-making prospectus.” The prospectus relating to the exchange offer is referred to herein as the “exchange offer prospectus.” The alternate pages to be inserted in the market-making prospectus include an alternate “Plan of Distribution” section. All other sections of the exchange offer prospectus will be included in the market-making prospectus.

1

[ALTERNATE SECTION FOR THE MARKET MAKING PROSPECTUS]

PLAN OF DISTRIBUTION

This prospectus is to be used by Morgan Stanley & Co. Incorporated (“Morgan Stanley”) in connection with offers and sales of the new notes in market-making transactions effected from time to time. Morgan Stanley may act as a principal or agent in such transactions, including as agent for the counterparty when acting as principal or as agent for both counterparties, and may receive compensation in the form of discounts and commissions, including from both counterparties when it acts as agent for both. Such sales will be made at prevailing market prices at the time of sale, at prices related thereto or at negotiated prices.

As of the date of this prospectus, affiliates of Morgan Stanley owned approximately 13.5% of our capital stock. See “Security Ownership of Certain Beneficial Owners and Management.” Because Morgan Stanley may purchase and sell new notes, and because this prospectus may be used by Morgan Stanley in connection with future offers and sales of new notes in market-making transactions effected from time to time, no estimate can be given as to the number and percentage of new notes that will be held by Morgan Stanley upon termination of any such sales.

We have been advised by Morgan Stanley that, subject to applicable laws and regulations, Morgan Stanley currently intends to make a market in the new notes following completion of the exchange offer. However, Morgan Stanley is not obligated to do so and any such market-making may be interrupted or discontinued at any time without notice. In addition, such market-making activity will be subject to the limits imposed by the Securities Act and the Exchange Act. There can be no assurance that an active trading market will develop or be sustained. See “Risk Factors—Risks Relating to the Notes, Including the Exchange Notes and Our Leveraged Capital Structure.”

Morgan Stanley has provided us with investment banking services in the past and may provide such services and financial advisory services to us in the future. Morgan Stanley acted as an initial purchaser in connection with the initial sale of the notes and received customary fees and was reimbursed expenses incurred in connection therewith. Additionally, a portion of the net proceeds of the initial offering of the new notes was used to repay the outstanding indebtedness under our existing term loan, including, to an affiliate of Morgan Stanley that is a lender under the existing term loan.

We have entered into a registration rights agreement with the initial purchasers of the new notes, including Morgan Stanley, in respect to the use by Morgan Stanley of this prospectus. Pursuant to such agreement, we have agreed to bear all registration expenses incurred under such agreement, and both we and Morgan Stanley have agreed to indemnify each other, and if applicable, contribute to the other, in accordance with the provisions of such agreement.

PART II. INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors, Officers, Managers and Members

US Oncology, Inc., the issuer of the exchange notes, is a corporation incorporated under the laws of the State of Delaware. Section 102(b)(7) of the Delaware General Corporation Law permits a corporation to include in its certificate of incorporation a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided, however, that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the Delaware General Corporation Law, which relates to unlawful payment of dividends and unlawful stock purchases and redemptions, or (iv) for any transaction from which the director derived an improper personal benefit.

Section 145 of the Delaware General Corporation Law provides that a corporation may indemnify any persons who were, are or are threatened to be made, parties to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was an officer, director, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his conduct was unlawful.

Section 145 of the Delaware General Corporation Law further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability asserted against him and incurred by him in any such capacity, arising out of his status as such, whether or not the corporation would otherwise have the power to indemnify him under Section 145 of the Delaware General Corporation Law.

Consistent with Section 145 of the Delaware General Corporation Law, Article VIII of the bylaws of US Oncology, Inc. provides that US Oncology, Inc. will indemnify any present or former director or officer of US Oncology, Inc. against those expenses which are actually and reasonably incurred in connection with any action, suit or proceeding, pending or threatened, in which such person may be involved by reason of being or having been a director or officer of the corporation.

In accordance with Section 102(b)(7) of the Delaware General Corporation Law, Article Sixth of the certificate of incorporation of US Oncology, Inc. provides that directors shall not be personally liable for monetary damages for breaches of their fiduciary duty as directors, except for liability (i) for any breach of the director’s duty of loyalty to US Oncology, Inc. or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the General Corporation Law of the State of Delaware or (iv) for any transaction from which the director derived an improper personal benefit. No amendment to or repeal of Article Sixth of the certificate of incorporation will apply to or have any effect on the liability or alleged liability of any director for or with respect to any acts or omissions of such director occurring prior to such amendment or repeal. No repeal or modification of Article Sixth of the certificate of incorporation will adversely affect any right of or protection afforded to a director of US Oncology, Inc. existing immediately prior to such repeal or modification.

Under Article VIII of US Oncology, Inc.’s bylaws, US Oncology, Inc. may purchase and maintain insurance on behalf of its directors, officers, employees, or agents against any liabilities asserted against such persons whether or not US Oncology, Inc. would have the power to indemnify such persons against such liability under the provisions of Article VIII. US Oncology, Inc. carries standard directors and officers liability coverage for its directors and officers and the directors and officers of its subsidiaries. Subject to certain limitations and exclusions, the policies reimburse US Oncology, Inc. for liabilities indemnified by US Oncology, Inc. and indemnify directors and officers against additional liabilities not indemnified by US Oncology, Inc.

Item 22. Undertakings

(a) Each of the undersigned registrants hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more that a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

II-5

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) Each of the undersigned registrants hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 22 or 13 of Form S-4, within one business day of receipt of such request, and to send the incorporated documents by first class mail or equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(c) Each of the undersigned registrants hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

(d) Insofar as indemnification for liabilities arising under Securities Act of 1933 may be permitted to directors, officers and controlling persons of each of the registrants pursuant to the foregoing provisions, or otherwise, the registrants have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by either of the registrants of expenses incurred or paid by a director, officer or controlling person of either of the registrants in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, each of the registrants will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

(e) Each of the undersigned registrants hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form.

(f) Each of the undersigned registrants hereby undertakes that every prospectus (i) that is filed pursuant to the immediately preceding paragraph or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-6
