Assuming the repayment and - 8 - termination of the Company's and the Guarantors' obligations under the Existing Credit Agreement, the execution, delivery and performance of this Agreement, the Indenture, the Securities, the Guarantees, each of the Refinancing Documents and any other agreement or instrument entered into or issued or to be entered into or issued by the Company or any of the Guarantors in connection with the consummation of the transactions contemplated by the Refinancing Transactions and this Agreement and in the Registration Statement and the Prospectus (including each of the Refinancing Transactions, the issuance and sale of the Securities and the Guarantees, the use of the proceeds from the sale of the Securities and the Guarantees as described in the Prospectus under the caption "Use of Proceeds") and compliance by the Company and the Guarantors with their respective obligations under this Agreement, the Indenture, the Securities, the Guarantees and each of the Refinancing Documents have been duly authorized by all necessary corporate action and do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or a default or a Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any of the Subsidiaries pursuant to, the Agreements and Instruments (except for such conflicts, breaches or defaults or liens, charges or encumbrances that, singly or in the aggregate, would not result in a Material Adverse Effect), nor will such action result in any violation of the provisions of the charter or by-laws of the Company or any of the Subsidiaries or any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any of the Subsidiaries or any of their assets, properties or operations. As used herein, a "Repayment Event" means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder's behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any of the Subsidiaries. (xiv) Absence of Labor Disputes. No labor dispute with the employees of the Company or any of the Subsidiaries exists or, to the knowledge of the Company and the Guarantors, is imminent, which may reasonably be expected to result in a Material Adverse Effect. (xv) Absence of Proceedings. Except as disclosed in the Prospectus there is not pending or, to the knowledge of the Company or any Guarantor, threatened any action, suit, proceeding, inquiry or investigation, to which the Company or any Subsidiary is a party, or to which the property of the Company or any Subsidiary is subject, before or brought by any domestic or foreign court or governmental agency or body, affecting (i) the possession by any of them of any Governmental License (as defined herein) currently held by any them, (ii) the accreditation of any of their respective laboratories with the College of American Pathologists ("CAP"), (iii) any of their qualification to perform services for and receive reimbursement from, Medicaid or Medicare, (iv) any of their ability to conduct their clinical testing business in any state or (v) any of them in any other way, which in the case of any of the foregoing, might reasonably be expected to result in a Material Adverse Effect, or which might reasonably be expected to materially and adversely affect the properties or assets of the Company and the Subsidiaries considered as one enterprise or the consummation of the - 9 - transactions contemplated in this Agreement or the performance by the Company of its obligations hereunder or under the Indenture, Securities, Guarantees or Refinancing Transactions. The aggregate of all pending legal or governmental proceedings to which the Company or any Subsidiary thereof is a party or of which any of their respective property or assets is the subject which are not described in the Prospectus, including ordinary routine litigation incidental to the business, could not reasonably be expected to result in a Material Adverse Effect. All of the descriptions set forth in the Prospectus of the legal and governmental proceedings by or before any court, governmental agency or body are true and accurate in all material respects. (xvi) Accuracy of Exhibits. There are no contracts or documents which are required to be described in the Registration Statement, the Prospectuses or the documents incorporated by reference therein or to be filed as exhibits thereto which have not been so described and filed as required.

The Company and each of the Guarantors, jointly and severally, agree to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act to the extent and in the manner set forth in clauses (i), (ii) and (iii) below, as follows: (i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto) including the Rule 430A Information and the Rule 434 Information, if applicable, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; (ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company; and (iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Joint Book-Running Managers), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above; provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company or the Guarantors by any Underwriter through the Joint Book-Running Managers expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430A Information and Rule 434 Information, if applicable, or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto); provided, further that the Company and the - 21 - Guarantors will not be liable to any Underwriter or any person controlling such Underwriter with respect to any such untrue statement or alleged untrue statement or omission or alleged omission made in any preliminary prospectus to the extent that the Company and the Guarantors shall sustain the burden of proving that any such loss, liability, claim, damage or expense resulted from the fact that the Underwriter sold Securities and Guarantees to a person to whom such Underwriter failed to send or give, at or prior to the written confirmation of the sale of such Securities and Guarantees, a copy of the Prospectus (as amended or supplemented) if the Company has previously furnished copies thereof to the Underwriter (sufficiently in advance of the Closing Time to allow for distribution of the Prospectus in a timely manner) and complied with their obligations hereunder and the loss, liability, claim, damage or expense of the Underwriter resulted from an untrue statement or omission or alleged untrue statement or omission of a material fact contained in or omitted from such preliminary prospectus (as amended or supplemented) which was corrected in the Prospectus (as amended or supplemented). The indemnified parties shall, however, be relieved of their obligation to first demand payment from the Company and the Guarantors or to wait such 30 calendar days if (i) the Company files a petition for relief under the United States Bankruptcy Code (the "Bankruptcy Code"), (ii) an order for relief is entered against the Company in an involuntary case under the Bankruptcy Code, (iii) the Company makes an assignment for the benefit of its creditors, or (iv) any court orders or approves the appointment of a receiver or custodian for the Company or a substantial portion of its assets. (b) Indemnification of Company, Guarantors, Directors and Officers. Each Underwriter severally agrees to indemnify and hold harmless the Company, the Guarantors, their directors, each of their officers who signed the Registration Statement, and each person, if any, who controls the Company or any Guarantor within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company and the Guarantors by such Underwriter through the Joint Book-Running Managers expressly for use in the Registration Statement (or any amendment thereto). (c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to such indemnified parties shall be selected by the Joint Book-Running Managers, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to such indemnified parties shall be selected by the Company. An indemnifying - 22 - party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. (d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 45 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party for the indemnified party's reasonable fees and expenses of counsel in accordance with such request prior to the date of such settlement. Notwithstanding the immediately preceding sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, an indemnifying party shall not be liable for any settlement effected without its consent if such indemnifying party (A) reimburses such indemnified party in accordance with such request to the extent it considers such request to be reasonable and (B) provides written notice to the indemnified party disputing the unpaid balance in good faith and substantiating the unpaid balance as unreasonable, in each case prior to the date of such settlement, subject to provision of notice by the indemnified party in accordance with (i) and (ii) above. SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors on the one hand and the Underwriters on the other hand from the offering of the Securities and the Guarantees pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Guarantors on the one hand and of the Underwriters on the - 23 - other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors on the one hand and the Underwriters on the other hand in connection with the offering of the Securities and the Guarantees pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities and the Guarantees pursuant to this Agreement (before deducting expenses) received by the Company and the Guarantors and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus, or, if Rule 434 is used, the corresponding location on the Term Sheet, bear to the aggregate initial offering prices of the Securities (including the Guarantees) as set forth on such cover. The relative fault of the Company and the Guarantors on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Guarantors, or by the Underwriters, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Guarantors and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities (including the Guarantees) underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, (a) each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and (b) each director of the Company and each Guarantor, and each person, if any, who controls the Company and each Guarantor, as the case may be, within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company and each Guarantor. The Underwriters' respective obligations to - 24 - contribute pursuant to this Section 7 are several in proportion to the principal amount of Securities (including the Guarantees) set forth opposite their respective names in Schedule A hereto and not joint. SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of the Subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Company or any Guarantor, and shall survive delivery of the Securities (including the Guarantees) to the Underwriters. SECTION 9. Termination of Agreement. (a) Termination; General. The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus, any material adverse change in the condition (financial or otherwise), earnings, business affairs or business prospects of the Company and the Subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there shall have occurred a downgrading in the rating assigned to the Securities or the Guarantees or any of the Company's or any Guarantors' other debt securities by any nationally recognized securities rating agency, or if such securities rating agency shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of the Securities, the Guarantees or any of the Company's or Guarantors' other debt securities or guarantees of debt securities or (iii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable to market the Securities and the Guarantees or to enforce contracts for the sale of the Securities and the Guarantees, or (iv) if trading in any securities of the Company has been suspended or limited by the Commission or the NASDAQ National Market System, or if trading generally on the American Stock Exchange or the New York Stock Exchange or in the NASDAQ National Market System has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, or (v) if a banking moratorium has been declared by either Federal or New York authorities. (b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such termination and remain in full force and effect. SECTION 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at Closing Time to purchase the Securities (including the Guarantees) which - 25 - it or they are obligated to purchase under this Agreement (the "Defaulted Securities"), the Representatives shall have the right, but not the obligation, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then: (a) if the number of Defaulted Securities does not exceed 10% of the aggregate principal amount of the Securities (including the Guarantees) to be purchased hereunder, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective obligations hereunder bear to the obligations of all non-defaulting Underwriters, or (b) if the number of Defaulted Securities exceeds 10% of the aggregate principal amount of the Securities (including the Guarantees) to be purchased hereunder, this Agreement shall terminate without liability on the part of any non-defaulting Underwriters. No action taken pursuant to this Section shall relieve any defaulting Underwriters from liability in respect of its default. In the event of any such default which does not result in a termination of this Agreement, either (i) the Representatives or (ii) the Company shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term "Underwriter" includes any person substituted for an Underwriter under this Section 10. SECTION 11. Default by the Company and the Guarantors. If the Company and the Guarantors shall fail at Closing Time to sell the number of Securities (including the Guarantees) that they are obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of any non-defaulting party; provided, however, that the provisions of Sections 1, 4, 6, 7 and 8 shall remain in full force and effect. No action taken pursuant to this Section shall relieve the Company or the Guarantors from liability, if any, in respect of such default. SECTION 12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to Merrill Lynch at North Tower, World Financial Center, New York, New York 10281-1201, attention of James Forbes, and CSFB at 11 Madison Avenue, 23rd Floor, New York, New York 10010, attention of both Harris Hyman and the Transaction Advisory Group, with a copy to Fried, Frank, Harris, Shriver & Jacobson, One New York Plaza, New York, New York 10004, attention of Valerie Ford Jacob, Esq.; and notices to the Company shall be directed to it at One Malcolm Avenue, Teterboro, New Jersey 07608, attention of General Counsel, with a copy to Shearman & Sterling, 599 Lexington Avenue, New York, New York 10022, attention of Stephen T.

Nothing - 26 - expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Company and the Guarantors and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters, the Company and the Guarantors and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation.

Exhibit A FORM OF OPINION OF COMPANY'S COUNSEL TO BE DELIVERED PURSUANT TO SECTION 5(b) (i) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware, and has corporate power and authority to own, lease and operate its properties, and to enter into and perform its obligations under the Purchase Agreement, the Indenture, the Notes and the New Credit Agreement. (ii) The Company has been duly qualified as a foreign corporation for the transaction of business and is in good standing under the laws of each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or be in good standing would not, individually or in the aggregate, have a Material Adverse Effect.
