Subject:
Development, License and Supply Agreement between Immunicon Corporation and Ortho-Clinical Diagnostics, Inc. dated August 17, 2000. 


Dear
Ed: 


        As
you know, all of the business of Advanced Diagnostic Systems is now conducted by Veridex, LLC, and Veridex, LLC assumes all the rights, interests, and obligations under the subject
Agreement. Veridex LLC represents that it is an "Affiliate" of Ortho-Clinical Diagnostics, Inc., and not a "Third Party" as those terms are defined in the subject Agreement, and that Veridex,
LLC has the full right
and power to assume all the rights, interests and obligations of Ortho-Clinical Diagnostics, Inc. under the subject Agreement without the prior written consent of Immunicon Corporation,
pursuant to section 16.3.1(a)(i) of the subject Agreement. 


        We
propose modifying the subject Agreement by nullifying all milestones described in section 5 that have not yet been fully performed (except for the milestone enumerated in
section 5.2.6, as clarified in the attached table (new Exhibit X), which milestone shall remain executory). However, the parties have jointly reviewed the project and have determined
that the CellTracks technology will not be available at a time sufficient to meet the portion of the milestone described in section 5.2.6 that refers to such technology. Accordingly, the last
sentence of such milestone shall be stricken from the Agreement and the adjustment described beneath the attached table shall be made. The following milestone provisions shall also be added in place
of those which have been nullified. Where the same event appears in more than one milestone, it establishes the order or timing in which events are to occur and does not require repetition of that
event. Additionally, a new section 3.5.1 is provided to completely replace that section as currently drafted in the Agreement and a new Exhibit Y is provided. All other terms and
conditions of the Agreement shall remain the same. Please indicate your acceptance by signing in the appropriate space below. 



        3.5.1    Immunicon
shall allocate a budget covering all Clinical Trial Expenses for Cellular Analysis Products for all monitoring, adjuvant, recurrence, companion biopsy, and
all other non-screening indications described or referred to in this Agreement, and shall bear up to Five Million dollars (US$5,000,000) for Clinical Trial Expenses for the first Cellular
Analysis Product for screening the general population for a major cancer as may be agreed to by the Steering Committee and provided, upon review of the data produced in such Clinical Trial, the
Steering Committee continues to approve such Clinical Trial. If such screening Clinical Trial Expenses exceed Five Million dollars (US$5,000,000) then Immunicon shall not be obligated to pay any such
excess amount and OCD shall pay up to Five Million dollars (US$5,000,000) of such additional screening Clinical Trial Expenses. If such additional screening Clinical Trial Expenses exceed Five Million
Dollars ($5,000,000), then the parties shall negotiate in good faith the future terms and conditions under which Clinical Trial for Cellular Analysis Products for such screening will be funded. OCD
shall also pay the reasonable incremental Clinical Trial Expenses attributable to indications in support of OCD products or methods for diagnostic testing 








or
testing for determinations regarding therapy based on [**]. Immunicon shall keep accurate records of the incremental Clinical Trial Expenses to be borne by OCD under this
Section 3.5.1 and shall provide OCD with an itemized list and description of such expenses in sufficient detail for OCD to assess their validity. Immunicon shall provide OCD with such a list
within 90 days of the accrual of such expenses. OCD shall pay to Immunicon such reasonable incremental Clinical Trial Expenses within 60 days of receipt of such list. The list provided
by Immunicon under this Section 3.5.1 shall be subject to the Audit Rights set forth in Section 3.6.3.

Exhibit Y: Requirements for the Large Volume Sample Processor to be used for the Prostate Cancer [**] Milestone(a)(b)    
    


	1.
	The
Large Volume Sample Processor (LVSP) must meet its functional requirements using whole blood collected in CellSave tubes.



	2.
	The
LVSP will process a large (up to [**] mLs) volume of whole blood and deliver a tumor cell enriched fraction into a standard AutoPrep sample tube, such that
the sample may then be placed on AutoPrep without further pre-processing.



	3.
	The
LVSP must demonstrate the number of recovered cells using the [**] mL blood volume reduction protocol is at least [**] the number
recovered when using [**] mL samples. This will be measured after LVSP processing, but before AutoPrep cell enrichment sample processing (AutoPrep input):



	•
	The
total number of leukocytes recovered from a [**] mL whole blood sample processed using the LVSP is at least [**] the
number of leukocytes recovered from [**] mLs of whole blood.






	4.
	Processing
of Tumor cell lines on the LVSP should not affect negatively their ability to be recovered by AutoPrep, or the accuracy of their reading on CellSpotter and/or CellTracks.
This will be measured after LVSP and AutoPrep / Cell enrichment sample processing (AutoPrep Output):



	•
	The
leukocyte carryover into a CellTracks chamber from LVSP processed samples should not exceed, on average, the leukocyte carryover of the sum of
[**] whole blood samples when processed on AutoPrep.



	•
	The
total number of spiked tumor cells recovered from a [**] mL whole blood sample processed using the LVSP is at least [**]
the number of tumor cells recovered from [**] of whole blood. Testing should be conducted at a tumor cell spike level of [**] mLs.






	5.
	The
Normal Reference Range should be less than or equal to [**] that of a single [**] mL tube. The functional sensitivity for tumor cell
detection per mL of sample (as determined by titrating spiked cells) must be [**] lower than that of a single [**] mL tube. For example, if the
functional sensitivity determined in a [**] mL sample is [**], then the functional sensitivity determined in a [**] mL sample
must be less than or equal to [**]. Working with the LVSPs New Product Proposal, or equivalent design control document, which incorporates the MECs, the Normal Reference Range
and the functional sensitivity shall be judged by the Steering Committee as to the LVSP's acceptability for its intended use.



	6.
	Demonstrate
that the LVSP processing, followed by AutoPrep sample enrichment is compatible with [**] analysis of the enriched cell population. The quality of
the [**] must be similar to that obtained from [**] mL samples. 




	(a)
	The
experiments used to demonstrate performance will be designed by Immunicon personnel, and performed according to written protocols. In advance of their execution, the Steering
Committee must agree that the design will yield results that adequately, and properly address the performance being tested.



	**

treatment request under 17 C.F.R. Sections 200.80(b)(4), 200.83 and 230.406.





	(b)
	The
analysis platform for feasibility experiments will be either CellSpotter or CellTracks. If Cell Spotter is used for feasibility demonstration, then equivalence must be
demonstrated on CellTracks
