Sellers understand that, in this context, “present fair saleable value” means the amount which may be realized within a reasonable time through a sale within such period by a capable and diligent businessperson from an interested buyer who is willing to purchase under ordinary selling conditions. In determining the present fair saleable value of Sellers’ and their Subsidiaries’ contingent liabilities (such as litigation, guarantees and pension plan liabilities), Sellers have considered such liabilities that could possibly become actual or matured liabilities.

(b) The consideration received by Sellers in connection with the transactions contemplated hereby constitutes reasonably equivalent consideration for the Purchased Assets. Immediately after giving effect to the transactions contemplated by this Agreement, Sellers shall have adequate capital to carry on and to perform their obligations under the Excluded Liabilities.

3.36

Assets

. The Purchased Assets and the Excluded Assets constitute all the properties, assets and rights forming a part of, used or held, and all such properties, assets and rights as are adequate for, the conduct of the Business as currently conducted and, with respect to contract rights, Sellers or their Subsidiaries are a party to and enjoy the right to the benefits of all Assumed Contracts, all of which properties, assets and rights constitute Purchased Assets except for the Excluded Assets.

3.37	Disclosure

. Sellers have delivered or made available to Buyer true, correct and complete copies of all documents, including all amendments, supplements and modifications thereof or waivers currently in effect thereunder, described in the Sellers’ Disclosure Letter.

3.38	No Limitation on Other Representation

. Except as otherwise expressly provided in this Agreement, nothing in any representation or warranty in this Agreement shall in any way limit or restrict the scope, applicability or meaning of any other representation or warranty made by Sellers herein.

5.4	No Solicitation

(a) Each of the Sellers agrees that it shall, and shall cause each of its Subsidiaries and its and their Representatives to, cease immediately and cause to be terminated

all existing activities, discussions or negotiations, if any, with any Persons with respect to, or that could reasonably be expected to result in any Acquisition Proposal. Except as provided in this Section 5.4, from the date of this Agreement until the earlier of termination of this Agreement or the Closing, Sellers shall not, and will cause its Subsidiaries and its and their Representatives to not, directly or indirectly:

(i) initiate, solicit or knowingly encourage or induce any inquiry, or take any action intended to facilitate the making or announcement of, any offer or proposal which constitutes or is reasonably likely to lead to any Acquisition Proposal;

(ii) participate or engage in any discussions or negotiations regarding an Acquisition Proposal or furnish or disclose any non-public information relating to either Seller or any of their Subsidiaries, or their businesses, assets, liabilities or prospects or afford access to the properties, books or records of either Seller or any of their Subsidiaries to, any Person regarding an Acquisition Proposal except as provided in Section 5.4(c);

(iii) enter into any letter of intent, agreement in principle, acquisition agreement, understanding or similar agreement contemplating or relating to an Acquisition Proposal (other than a confidentiality and standstill agreement as contemplated in this Section 5.4); or

(iv) approve, endorse or recommend any Acquisition Proposal (except to the extent specifically permitted by this Section 5.4).

(b) Sellers shall promptly notify Buyer (but in no event later than the end of the next Business Day) after receipt by a Seller of any Acquisition Proposal or any request for information or inquiry which could reasonably be expected to lead to an Acquisition Proposal. Such notice shall identify the Person or group making such Acquisition Proposal, request or inquiry and include a copy of all written materials provided in connection with such Acquisition Proposal, request or inquiry or, if such Acquisition Proposal, request or inquiry is not in writing, provide a summary of the material terms and conditions of any such Acquisition Proposal, request or inquiry. After receipt of the Acquisition Proposal, request or inquiry, Sellers shall promptly keep Buyer informed in all material respects of the status and details (including material amendments or proposed material amendments) of any such Acquisition Proposal, request or inquiry.

(c) If, prior to obtaining the Stockholder Approval either Seller receives an Acquisition Proposal that was not solicited in violation of Section 5.4(a) that the board of directors of Sellers determines in good faith, after consultation with outside counsel and its financial advisor (1) constitutes a Superior Proposal or (2) could reasonably be expected to result in a Superior Proposal, Sellers shall promptly provide to Buyer written notice that shall state expressly (A) that such Seller has received an Acquisition Proposal that constitutes a Superior Proposal or that could reasonably be expected to result in a Superior Proposal, and (B) the identity of the Person (the “Third Party”) making such Acquisition Proposal and the material terms and conditions of the Acquisition Proposal (the “Superior Proposal Notice”) and may then take the following actions (either directly or through its Subsidiaries or any of their Representatives) if the board of directors of Sellers determines, after consultation with outside

- 53 -

counsel, that to do so is necessary to comply with its fiduciary obligations to Sellers’ stockholders under applicable law:

(i) furnish nonpublic information to the Third Party, provided, that (A) prior to so furnishing, Sellers receive from the Third Party an executed confidentiality agreement containing customary standstill provisions and other terms and conditions that are no less restrictive to such Third Party than the terms and conditions of the Confidentiality Agreement, and (B) on the date of the provision of any non-public information to such Third Party, Sellers furnish a copy of such non-public information of Sellers to Buyer (to the extent such non-public information has not been previously so furnished); and

(ii) participate or engage in any discussions or negotiations with the Third Party with respect to the Acquisition Proposal.

(d) For a period of not less than three Business Days prior to Sellers accepting a definitive Superior Proposal, Sellers shall, if requested by Buyer, negotiate in good faith with Buyer to revise this Agreement so that the Acquisition Proposal that constituted a Superior Proposal no longer constitutes a Superior Proposal. The terms and conditions of this Section 5.4(d) shall again apply to any subsequent Superior Proposal after any changes made to this Agreement.

(e) Except as expressly permitted by Section 5.4(f), neither Sellers board of directors nor any committee of Sellers board of directors shall (i) withdraw or modify, or propose publicly to withdraw or modify, in a manner adverse to Buyer, Sellers’ Board Recommendation or (ii) approve or recommend, or propose publicly to approve or recommend, any Acquisition Proposal (any action described in the foregoing (i) or (ii) being referred to as a “Change of Recommendation”). Any such Change of Recommendation or the entry by a Seller into any letter of intent, agreement in principle, acquisition agreement, understanding or similar agreement contemplating or relating to an Acquisition Proposal shall not change the approval of Sellers board of directors for purposes of causing any state takeover statute or other state law to be applicable to the transactions contemplated hereunder.

(f) In the event that prior to obtaining the Stockholder Approval, Sellers board of directors determines in good faith, after consultation with its financial advisor and outside counsel, that an Acquisition Proposal not solicited in violation of Section 5.4(a) has not been withdrawn and continues to constitute a Superior Proposal following the expiration of the three Business Day period referenced in Section 5.4(d), Sellers may effect a Change of Recommendation and/or terminate this Agreement in accordance with Section 10.1(d)(i); provided that Sellers board of directors has concluded in good faith, following consultation with outside legal counsel, that, in light of such Superior Proposal, the failure of Sellers board of directors to effect a Change of Recommendation or to terminate this Agreement is necessary to comply with its fiduciary obligations to either of Sellers stockholders under applicable law; provided further, however that Sellers shall not terminate this Agreement pursuant to Section 10.1(d)(i), and any purported termination pursuant to Section 10.1(d)(i) shall be void and of no force or effect, unless Sellers shall have complied in all material respects with all of the provisions of this Section 5.4, including the notification provisions in this Section 5.4, and with

- 54 -

all applicable requirements of Section 10.3 (including the payment of the Termination Fee prior to or concurrently with such termination).

(g) Sellers shall provide Buyer with three Business Days prior notice (or such lesser prior notice as is provided to the members of Sellers board of directors) of any meeting of Sellers board of directors or committee of Sellers board of directors at which the Sellers board of directors or committee thereof is reasonably expected to discuss any Acquisition Proposal.

Nothing contained in this Section 5.4 or elsewhere in this Agreement shall prohibit Parent from (x) taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a) under the Exchange Act, or (y) making any disclosure to the stockholders of the Sellers if Parent’s board of directors determines in good faith (after consultation with its outside legal counsel) that the failure to make such disclosure would be reasonably expected to be a breach of its duty of candor under applicable law; provided, however, that any action taken or disclosure made under this Section 5.4 shall not limit or modify the effect that any such action or disclosure may have under any other provision of this Agreement.

5.5	Stockholder Meeting

(a) Parent shall, as promptly as reasonably practicable following the execution of this Agreement and subject to Section 5.4(f), establish a record date for, duly call, give notice of convene and hold a meeting of its stockholders solely for the purpose of seeking the Stockholder Approval (“Stockholder Meeting”). In connection with the Stockholder Meeting, Parent, acting through the Parent board of directors, will (i) subject to Section 5.4(f) make the Sellers’ Board Recommendation, (ii) use its commercially reasonable efforts (including postponing or adjourning the Stockholder Meeting to solicit additional proxies) to obtain and shall take all other reasonable action necessary or advisable to secure, the Stockholder Approval and (iii) otherwise comply with Parent’s Certificate of Incorporation, bylaws and applicable law in connection with such meeting.

(b) As promptly as reasonably practicable after the date of this Agreement, Parent shall prepare and file with the SEC, and shall use its commercially reasonable efforts to have cleared by the SEC, the Proxy Statement (together with any amendments thereof or supplements thereto) to be distributed in connection with the Stockholder Meeting. Buyer and Sellers each shall promptly and timely provide all information relating to its respective businesses or operations necessary for inclusion in the Proxy Statement to satisfy all requirements of applicable state and United States federal securities laws and neither the Proxy Statement nor any amendment or supplement to the Proxy Statement, will be filed or made by the Sellers, in each case without providing Buyer a reasonable opportunity to review and comment thereon.

(c) Sellers shall notify Buyer of the receipt of any comments of the SEC with respect to the Proxy Statement and of any requests by the SEC for any amendment or supplement thereto or for additional information and shall provide a copy of such comments or requests to Buyer promptly after receipt, and shall promptly provide to Buyer copies of all correspondence

- 55 -

between Sellers or any Representative Sellers and the SEC. Sellers shall give Buyer and its counsel the reasonable opportunity to review and comment on any proposed responses to comments, which review shall be concluded as promptly as possible after the receipt by Buyer of Sellers proposed responses to SEC comments or other correspondence to the SEC. If at any time after the date the Proxy Statement is mailed to Parent’s stockholders and prior to the Stockholder Meeting any information relating to the Sellers or Buyer, or any of their respective Affiliates, directors, or officers, should be discovered by the Sellers or Buyer which should be set forth in an amendment or supplement to the Proxy Statement, so that either such document would not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the Party that discovers such information shall promptly notify the other Parties hereto and Parent shall promptly file an amendment or supplement describing such information promptly with the SEC and, to the extent required by applicable law or the SEC, disseminated to Parent’s stockholders.

As promptly as reasonably practicable after the Proxy Statement has been cleared by the SEC, Parent shall mail the Proxy Statement to the holders of Parent’s common stock as of the record date established for the Stockholder Meeting. Unless the board of directors of Parent shall have effected a Change in Recommendation, the Proxy Statement shall include the Seller Board recommendation, provided that nothing herein shall prohibit Parent from supplementing or amending the Proxy Statement if there has been a Change in Recommendation.

To be useful in satisfying the Patent Condition, the technical disclosure contained in any such evidence must make the showing of facts, in character and weight, to establish reduction to practice of the Invention as claimed in the Invention Patent prior to the effective date of the reference cited in the Other Claim, or conception of the Invention as claimed in the Invention Patent prior to the effective date of the reference cited in the Other Claim coupled with due diligence from prior to said date to a subsequent reduction to practice or to the filing of the application for the Invention Patent.

Guarantee

(a) Clarient hereby irrevocably and unconditionally guarantees to Sellers, as primary obligor and not merely as surety, the performance of all obligations hereunder of Buyer and the due and punctual payment by Buyer in full of any amounts payable by Buyer pursuant to this Agreement.

(b) To the fullest extent permitted by applicable law, Clarient waives presentment to, demand of payment from and protest to Sellers, and also waives notice of acceptance of its guarantee and notice of protest for nonpayment. To the fullest extent permitted by applicable law, the obligations of Clarient hereunder shall not be affected by (i) the failure of Sellers to assert any claim or demand or to exercise or enforce any right or remedy against Buyer under the provisions of this Agreement or otherwise, or (ii) any rescission, waiver, amendment or modification of, or any release from any of the terms or provisions, of this Agreement.

- 60 -

(c) Clarient agrees that the guarantee pursuant to this Section 7.9 constitutes an absolute, unconditional, present and continuing guarantee of payment and not of collection, and waives any right to require that any resort be had by Sellers to (i) Sellers’ rights against any other person, including Buyer, or (ii) any other right or remedy available to Sellers by contract, applicable law or otherwise. It is the intent of the guarantee pursuant to this Section 7.9 that Sellers shall have resort to Clarient without asserting or resorting to any remedy against Buyer and without demand to it, as though Clarient were primarily liable for any payment due hereunder.

7.10	Collection of Accounts Receivable.

(a) Subject to subsections (b) and (c) below, no later than five business days following the 90^th day following the Closing Date, Buyer shall remit to Parent an amount equal to 57% of all amounts received by Buyer in payment of accounts receivable existing at the Closing Date, to the extent such payments (i) are received by Buyer within 90 days following the invoice of such amount by a Seller and (ii) reflect payment due by customers in respect of Instruments sold by a Seller prior to the Closing Date (such amount, the “Remittance Amount”); provided, however, that the Remittance Amount shall not exceed the amount of Sellers’ accounts payable assumed by Buyer at Closing pursuant to this Agreement.

(b) All amounts received by Buyer and its Affiliates from a customer during the time period described in subsection (a) shall be first applied to the oldest debt owed by such customer (i.e. by due date), unless (i) such oldest debt has been disputed by the customer, in which case the payment will be allocated to the next oldest undisputed debt owed by such customer or (ii) the payment refers to an invoice number, in which case the payment will be allocated to the invoiced debt notwithstanding clause (i) above.

(c) Buyer shall use its commercially reasonable efforts to collect payment of such accounts receivable consistent with Clarient’s efforts to collect Clarient’s other accounts receivable of like type and amount; provided however that neither Buyer nor Clarient shall be under any obligation to (i) institute any legal proceedings to collect such accounts receivable or (ii) take any action Clarient determines in its sole discretion to be adverse to either Buyer or Clarient. Sellers shall not, except upon Buyer’s prior written consent, institute collection proceedings with respect to such accounts receivable. Notwithstanding the foregoing, to the extent that Buyer reasonably determines in good faith that due to oversight or otherwise, amounts that should have been considered in calculating the Adjustment Amount or amounts by which the Assumed Liabilities were underaccrued for by Sellers on the Closing Balance Sheet were excluded from such calculations, Buyer shall be permitted to offset such amounts against the remittance of the Remittance Amount.

7.11	Hired Employees.

(a) No later than immediately prior to the Closing, Parent shall terminate, or shall cause to be terminated, each Hired Employee's employment with Parent and its Subsidiaries and Parent shall satisfy, or shall cause to be satisfied, all Parent’s obligations to such Hired

- 61 -

Employees arising in connection with such Hired Employees' employment with Parent and its Subsidiaries and the termination thereof.

(b) Immediately after the Closing, Clarient shall offer employment with Clarient or Buyer to each of the Hired Employees, (i) at a salary level substantially comparable to that in effect with respect to each such Hired Employee as of the date hereof, and (ii) with employee benefits which are, with respect to each such Hired Employee, no less favorable in the aggregate than the benefits provided to similarly situated employees of Clarient.

(c) No provision of this Section 7.11 shall create any third-party beneficiary or other rights in any Hired Employee, including without limitation in respect of continued employment with Buyer or its Affiliates for any period of time. No provision of this Section shall obligate Buyer or any of its Affiliates to adopt or maintain any employee benefit plan or arrangement at any time.
