<Page> EXHIBIT 10.03 PROCESSING AGREEMENT THIS PROCESSING AGREEMENT (the "Agreement") is made and entered into this 20th day of December, 2001, between Akorn, Inc., a Louisiana Corporation ("Akorn") and NeoPharm, Inc., a Delaware Corporation ("NeoPharm"). WHEREAS, NeoPharm is a pharmaceutical company which has developed certain chemotherapeutic agents (the "Products"); WHEREAS, Akorn owns and operates a lyophilization facility located at 1222 West Grand Avenue, Decatur, Illinois (the "Facility") and has the ability and capacity to process and finish pharmaceutical products; and WHEREAS, NeoPharm desires to contract with Akorn to process and finish the Products at the Facility, and Akorn desires to provide such services, on the terms and conditions set forth herein NOW, THEREFORE, in consideration of the mutual covenants and promises set forth herein, the parties agree as follows: ARTICLE I PROCESSING ESTIMATE/DELIVERY OF PRODUCTS Section 1.1. PROCESSING ESTIMATE. At least thirty (30) days prior to the Effective Date (as defined herein), and at least thirty (30) days prior to the commencement of each twelve (12) month period thereafter, NeoPharm shall deliver to Akorn its good faith estimate (the "Estimate") of the quantity of Products to be Processed (as defined herein) by Akorn hereunder for the upcoming twelve (12) month period. Such estimate shall be non-binding, and NeoPharm shall update the Estimate quarterly based upon its expected Processing needs. Akorn agrees to allocate to the Processing of NeoPharm's Products no less than fifteen percent (15%) of the Facility's Processing capacity during every twelve (12) month period during the Term of this Agreement; the actual allocation of the Facility's capacity to NeoPharm for such period shall be agreed upon by the parties and is referred to herein as the "Processing Maximum". Processing Capacity shall be measured in terms of hours usage of the Facility. NeoPharm shall have the right to audit Akorn's books and records to ascertain compliance with this Section 1.1. Section 1.2. PURCHASE ORDERS. From time to time, NeoPharm shall provide Akorn with a purchase order (the "Purchase Order") which shall set forth the Product to be Processed and the quantity of Bulk Product to be Processed by Akorn (the "Batch"). Akorn shall provide NeoPharm with written acceptance of the Purchase Order, which acceptance shall set forth the date the Processing Run (as defined herein) for the Batch covered by such Purchase Order shall commence (the "Processing Run Commencement Date"). Akorn agrees that the Pocessing Run Commencement Date shall be no later than fourteen (14) days after Akorn's receipt of the <Page> Purchase Order. Akorn shall use its best efforts to accommodate NeoPharm's request to amend a Purchase order to modify the size of a Batch to be Processed. Section 1.3. ESTIMATED YIELD. Upon Akorn's acceptance of a Purchase Order, Akorn shall calculate the estimated Final Product to be manufactured (the "Estimated Yield") from the Batch that is the subject of the Purchase Order. The Estimated Yield factor to be applied to each Purchase Order shall be based upon the optimum yield determined from the first (3) Processing Runs of a particular Product. Such determination and each such Processing Run shall be performed and conducted in the presence of a NeoPharm representative. In the event NeoPharm disagrees with Akorn's Estimated Yield, the Parties shall in good faith agree upon a third party to review the data Akorn utilized to calculate the Estimated Yield. The findings of such third party shall be binding on both parties. In the event that the actual yield of any Batch is less than ninety-five percent (95%) of the Estimated Yield, NeoPharm shall be entitled to an investigation of the reason(s) for the reduced yield of the Batch, and NeoPharm shall be entitled to an equitable reduction (the "Yield Credit") in the Processing Fee (as defined herein). Section 1.4. DELIVERY OF BULK PRODUCTS. At least fifteen (15) business days prior to each Processing Run Commencement Date, NeoPharm shall deliver to Akorn sufficient amounts of Bulk Product for such Processing Run along with any applicable vial labeling materials. For purposes of this Agreement, Bulk Product shall mean formulated solutions of the Products. NeoPharm warrants that all Bulk Product provided hereunder shall meet all applicable specifications and shall have been produced in compliance with applicable federal, state and local laws and regulations, including, without limitation, the Good Manufacturing Practices Regulations ("GMPs") of the United States Food and Drug Administration ("FDA"), 21 C.F.R. part 211, in effect at the time of Processing. In connection with the delivery of Bulk Product, NeoPharm shall provide Akorn with written certification of the sterility of Bulk Product. Section 1.5. OWNERSHIP/RISK OF LOSS. NeoPharm shall own all Bulk Product delivered by NeoPharm and all Finished Product (as defined herein) Processed by Akorn and, except in a case giving rise to Akorn's indemnification responsibilities hereunder, NeoPharm shall bear the risk of loss with respect to such materials. ARTICLE II PROCESSING OF BULK PRODUCTS Section 2.1. PROCESSING OBLIGATIONS. Commencing with each Processing Run Commencement Date, Akorn shall Process the Bulk Product corresponding to the applicable Purchase Order in accordance with the terms of this Article II (each a "Processing Run"). For purposes of this Agreement, "Processing" shall mean filling into vials, lyophilizing, inspecting and packaging the Bulk Product in order to produce finished pharmaceutical dosage forms of the Products (the "Finished Product"). The parameters (the "Processing Parameters") under which Akorn shall Process the Bulk Product shall be mutually agreed upon by the Parties at least thirty (30) days prior to the Effective Date and shall be attached hereto as Schedule 2.1. Any amendments and/or additions to the Processing Parameters or the equipment, test methods, 2 <Page> specifications or any other requirement of this Agreement or with respect to the operation of the Facility, must be mutually agreed to by the parties in writing and shall be attached to Schedule 2.1. Notwithstanding the foregoing and in addition to any supplemental parameters agreed to by the parties with respect to a particular Processing Run, Akorn's Processing at a minimum shall consist of the following components: (a) Preparation and retention of the master production and control records required by the FDA for each Product pursuant to 21 CFR 600.12 (the "Batch Records") as approved by Akorn and NeoPharm. (b) Compliance with the applicable standards from the USP-NF guidelines. (c) Furnishing vials, stoppers and seals for the Products and conducting the appropriate inspection, testing and release thereof.

(i) Storage of quarantined vials at mutually agreed upon temperatures until instructed by NeoPharm to ship the Finished Product. (j) Shipping of the Finished Product in accordance with NeoPharm's specifications. Section 2.2. ADDITION OF OTHER PRODUCTS TO THE AGREEMENT. NeoPharm may add additional pharmaceutical products to be Processed by Akorn. The parties shall mutually agree upon any Processing Parameters and the Processing Fee for such additional products. Section 2.3. REPRESENTATIONS AND WARRANTIES OF AKORN. Akorn agrees that in performing the Processing services hereunder, it shall comply with applicable GMPs and that it shall use its best efforts to maintain the Facility in such a fashion as to be in compliance with all applicable federal, state and local rules and regulations. Akorn agrees that it shall maintain all licenses and permits required by any applicable federal, state or local agency, including but not limited to the FDA, in order to operate the Facility and provide the Processing services required hereunder. Without limiting the generality of the foregoing, Akorn agrees that it will cause its 3 <Page> employees and agents to follow all procedures developed and implemented in connection with the removal of the warning letter sanctions pursuant to Form 483 or current GMP regulations issued or imposed by the FDA with regard to the Facility. Akorn also agrees to store all manufacturing and laboratory records on the site where the Processing is performed and to keep such records readily available. Further, Akorn represents and warrants that it shall use its best efforts to insure that all filtration, filling and lyophilization of the Product by Akorn shall be done in an aseptic processing environment and in accordance with the Processing Parameters. Section 2.4. FACILITIES INSPECTION. During the Term of this Agreement, NeoPharm shall have the right, at its expense, to audit the Facility for Akorn's compliance with GMPs and any other applicable laws. NeoPharm agrees to provide Akorn with reasonable prior notice of the date of such audit. In addition to the foregoing, NeoPharm shall have the right to designate an individual to be at the Facility to monitor each Processing Run. NeoPharm agrees that its employees or agents who inspect the Facility or who are on site at the Facility during a Processing Run will comply with Akorn's rules, regulations and GMPs. Section 2.5. AKORN OBLIGATION TO MEET REQUIREMENTS. Akorn agrees to fulfill, in each twelve (12) month period during the Term of this Agreement (as defined herein), all Purchase Orders placed by NeoPharm up to one hundred percent (100%) of NeoPharm's most recently updated Estimate. Akorn shall use reasonable efforts to supply any quantity ordered by NeoPharm of Product in excess of the Estimate subject to Akorn's production scheduling capabilities and commitments to other customers. Section 2.6. SUBCONTRACTING. Akorn shall not pass to a third party any work entrusted to it under this Agreement without first obtaining NeoPharm's written approval of such arrangements, which approval shall not be unreasonably withheld. Section 2.7. QUALITY ASSURANCE DEPARTMENT. Akorn agrees that at all times during the term of this Agreement, it shall maintain a quality assurance department (the "Quality Assurance Department") for purposes of monitoring the quality of Akorn's Processing hereunder and for purposes of approving each Batch Processed hereunder. Akorn agrees that upon NeoPharm's request, it shall provide NeoPharm with copies of the policies, procedures and findings of the Quality Assurance Department. ARTICLE III SHIPMENT AND STORAGE Section 3.1. STORAGE. Akorn shall store and handle the Bulk Product and Finished Product as required by the Processing Parameters. Akorn shall take such actions as are reasonably necessary to protect the Bulk Product and Finished Product from damage and deterioration. Vials of Finished Product will be stored at the recommended controlled temperature until shipped as instructed by NeoPharm. 4 <Page> Section 3.2. RELEASE OF FINISHED PRODUCT. Upon Akorn's Quality Assurance Department's written release of a Batch of Finished Product, Akorn shall promptly ship the Finished Product to NeoPharm or, at NeoPharm's discretion, warehouse Finished Product, in accordance with FDA and GMP warehousing procedures, for a maximum of thirty (30) days at no cost, and thereafter at charges to be mutually agreed upon, to the extent warehousing space is available. Akorn shall provide NeoPharm with properly completed Batch Records, prepared in conformance with the Processing Parameters, within five (5) days following Akorn's written release of such Batch but, in no event more than four (4) weeks from the date the Processing Run is completed (i.e., the date the filling or lyophilization is completed). Section 3.3. TRANSFER OF FINISHED PRODUCT TO NEOPHARM. Finished Product shall be shipped to NeoPharm in accordance with NeoPharm's written instructions. Unless otherwise agreed to in writing by the Parties, there shall be only one shipment per Batch of Finished Product. NeoPharm shall be responsible for all costs associated with the shipment of Finished Product Section 3.4. REJECTION. NeoPharm may reject any Batch of Finished Product failing to meet any of the Processing Parameters by providing Akorn with written notice of such rejection (the "Rejection") within sixty (60) days following NeoPharm's receipt of the applicable Batch Records and written notice from Akorn stating that Akorn's Quality Assurance Department has approved the Batch. Any rejection by NeoPharm pursuant to this Section 3.4 shall be accompanied by a report of analysis, including a product sample from the Batch analyzed. NeoPharm's failure to reject a Batch of Finished Product in the manner set forth above shall constitute acceptance thereof except to the extent that any defect in the Batch was not discovered by NeoPharm after exercising due diligence and using customary testing procedures accepted in the industry and provided that NeoPharm notifies Akorn of any such defect within a reasonable time after NeoPharm discovers or should have discovered the defect and before any substantial change in the condition of the Batch which is not caused by such defect. In the event Akorn accepts NeoPharm's Rejection, NeoPharm shall be entitled to a credit against the Processing Fee (the "Rejection Credit") equal to the Processing Fee for such Batch and the cost, not to exceed $25,000, of NeoPharm's Bulk Product. In the event the Parties can not agree upon whether the Rejection was justified, the Parties shall mutually agree upon a third party to test samples of such Batch and to review records and test data and other relevant information developed by both parties relating thereto to ascertain whether the Batch was manufactured in accordance with the Processing Parameters. The findings of such third party shall be binding on both parties. If the third party determines that the Batch was manufactured in accordance with the Processing Parameters, NeoPharm shall be deemed to have accepted the affected Batch. If the third party determines that the Batch was not manufactured in accordance with the Processing Parameters, NeoPharm shall be entitled to the Rejection Credit. The Parties shall share the costs of any such third party testing. In the event a Batch was properly Rejected, Akorn agrees that NeoPharm shall be entitled to a replacement Processing Run, regardless of whether such replacement Processing Run will cause NeoPharm to exceed the Processing Maximum. 5 <Page> ARTICLE IV PRICE OF MANUFACTURE Section 4.1. PRICE. In consideration of the Processing provided by Akorn hereunder, NeoPharm agrees to pay Akorn a processing fee (the "Processing Fee"), as modified by the Yield Credit or the Rejection Credit, if applicable. The Processing Fee shall be mutually agreed upon by the Parties at least thirty (30) days prior to the Effective Date based upon the Processing Parameters for each Product, after a trial run if necessary, and shall be attached hereto as Schedule 4.1. Section 4.2. MOST FAVORED PRICING. Akorn agrees that the Processing Fee charged to NeoPharm hereunder shall be no higher than the lowest fee charged by Akorn to any customers with similar processing requirements for Processing at the Facility, regardless of any discounts afforded to such other customers. NeoPharm shall have the right to audit Akorn's books and records to ascertain compliance with this Section 4.2. ARTICLE V TERM AND TERMINATION Section 5.1. TERM. This Agreement shall have an initial term (the "Initial Term") commencing on the date the warning letter sanctions imposed by the FDA pursuant to Form 483 or current GMP regulations on Akorn and/or the Facility have been removed (the "Effective Date") and ending on THE LATER OF (i) the fifth (5th) anniversary of the Effective Date, or (ii) two (2) years after the date on which Akorn pays all amounts of principal and accrued interest under that certain Promissory Note (the "Note"), dated December 20, 2001, issued by Akorn to NeoPharm in exchange for a loan in principal amount of Three Million Two Hundred Fifty Thousand Dollars ($3,250,000) plus interest. This Agreement will automatically extend for two additional, five-year terms (each, an "Additional Term") beyond the Initial Term, provided, however, that either NeoPharm or Akorn may terminate this Agreement at the end of the Initial Term or an Additional Term, as the case may be, by sending a termination notice ninety (90) days prior to the end of such Initial Term or Additional Term. Notwithstanding the foregoing, in the event the warning letter sanctions pursuant to Form 483 or current GMP regulations have not been removed by June 30, 2003 or in the event the Akorn has not received validation from the FDA with respect to Processing NeoPharm's Products by such date, NeoPharm may terminate this Agreement upon written notice to Akorn.
