ORCHID CELLMARK INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(1) Basis of Presentation

The accompanying unaudited consolidated financial statements of Orchid Cellmark Inc. and its subsidiaries (the Company) have been prepared
in accordance with accounting principles generally accepted in the United States of America (US) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the
information and footnotes required by accounting principles generally accepted in the US (GAAP) for complete annual financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary
for a fair presentation have been included. Interim results are not necessarily indicative of results that may be expected for a full year.

The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in the Companys Annual
Report on Form 10-K, for the year ended December 31, 2010, as amended (the Annual Report), as filed with the Securities and Exchange Commission (SEC) on April 29, 2011.

There have been no changes to the Companys critical accounting policies as disclosed in the Annual Report.

(2) Net Loss per Share

Net loss per share is computed in accordance with FASB ASC 260-10, Earnings Per Shareby dividing the net loss for the period by
the weighted average number of shares of common stock outstanding. During each period presented, the Company has certain options that have not been included in the calculation of diluted net loss per share because to do so would be anti-dilutive. As
such, the numerator and the denominator used in computing both basic and diluted net loss per share for each period are equal.

(3) Fair
Value Measurements and Marketable Securities

Fair value of financial and non-financial assets and liabilities is defined
as an exit price, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The three-tier hierarchy for inputs used to measure fair
value, which prioritizes the inputs to valuation techniques used to measure fair value, is as follows:

Level 1  quoted prices
(unadjusted) in active markets for identical assets or liabilities.

Level 2  quoted prices for similar assets and liabilities in active
markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.

Level 3  unobservable inputs based on the Companys assumptions used to measure assets and liabilities at fair value.

A financial asset or liabilitys classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The assessment of the
significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy.

(8) Restructuring

The consolidation of the Companys East Lansing, Michigan paternity testing operations into its Dayton, Ohio facility and the consolidation of its Nashville CODIS testing operation into its Dallas,
Texas facility were both substantially completed as of December 31, 2010. As such, no additional restructuring charges were incurred in the first quarter of 2011, as compared to $444 thousand for the three months ended March 31, 2010. The

completed this consolidation during the quarter ended March 31, 2011. The expenses in 2010 relate primarily to employee severance costs and facility closure costs.

The restructuring liability is included as part of accrued expenses and other current liabilities on the Companys consolidated balance sheet.

As of March 31, 2011 and December 31, 2010, the Company had approximately $127 thousand and $290 thousand, respectively, in
restructuring accruals outstanding that are related to severance and facility obligations.

(9) Income Taxes

The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. The tax years 2007 through 2009 remain open to examination by the UK taxing authorities and the
tax years 2007 through 2009 remain open to examination by the US taxing authorities. In addition, the US taxing authorities may examine the tax years from the Companys inception in 1995 through 2006, but are barred from adjusting the tax
liabilities in excess of the net operating losses generated in any of those tax years.

(10) Recently Issued Accounting Pronouncements

There have been no recent accounting pronouncements or changes in accounting pronouncements during the three months ended
March 31, 2011, as compared to the recent accounting pronouncements described in the Companys Annual Report on Form 10-K for the fiscal year ended December 31, 2010, that are of significance, or potential significance to the
Company.

(11) Comprehensive Loss

Comprehensive income is comprised of net earnings, foreign currency translation adjustments, and unrealized gains and losses on available-for-sale securities. Total comprehensive loss for the three months
ended March 31, 2011 and 2010 was $1.4 million and $2.8 million, respectively. The difference from net loss for the three months ended March 31, 2011 and 2010 consists of foreign currency translation adjustments, and unrealized gains and
losses on available-for-sale securities. Accumulated other comprehensive loss as reflected in the consolidated balance sheets consists of cumulative foreign currency translation adjustments of $735 thousand and unrealized loss on available-for-sale
securities of $1 thousand.

(12) Agreement and Plan of Merger

On April 5, 2011, the Company entered into an Agreement and Plan of Merger (the Merger Agreement), with Laboratory Corporation of America Holdings, a Delaware corporation
(LabCorp), and OCM Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of LabCorp (Purchaser), pursuant to which LabCorp will acquire the Company in a two-step transaction. Pursuant to the Merger
Agreement, and subject to its terms and conditions, on April 19, 2011, Purchaser commenced a cash tender offer to purchase all outstanding shares of the Companys common stock, par value $0.001 per share (the Common Stock),
including, to the extent outstanding, the associated preferred stock purchase rights (the Rights) issued under the Rights Agreement, dated July 27, 2001, as amended, between the Company and American Stock Transfer & Trust
Company, as rights agent (such Rights, to the extent outstanding, together with the shares of the Common Stock, the Shares), at a purchase price of $2.80 per share, net to the seller in cash, without interest thereon and subject to any
required tax withholding.

Unless extended, the tender offer is currently scheduled to expire at 5:00 p.m., New York City
time, on Tuesday, May 17, 2011, after which time, if all conditions to the tender offer have been satisfied or waived, Purchaser will accept for payment all Shares validly tendered pursuant to the offer and not validly withdrawn. If successful,
the tender offer will be followed by the merger of Purchaser into the Company, with the Company being the surviving corporation and becoming a wholly owned subsidiary of LabCorp. In the merger, Shares not purchased in the tender offer (other than
Shares held by stockholders who properly demand and perfect their appraisal rights under Delaware law) will be converted into the right to receive the same $2.80 per share cash payment, without interest, paid in the tender offer.

In addition, the Merger Agreement includes termination provisions for both the Company and
LabCorp and provides that, in connection with the termination of the Merger Agreement under certain circumstances, the Company would be obligated to pay LabCorp a termination fee of $2.5 million and reimburse LabCorp for certain out-of-pocket
expenses up to $0.5 million. The consummation of the tender offer and the merger are subject to conditions, including the Purchasers acquisition of a majority of the outstanding shares of the Companys Common Stock on a fully-diluted
basis. Neither the tender offer nor the merger is subject to a financing condition. The Company can provide no assurance that these transactions will be completed. Except where explicitly stated otherwise, information contained in this report does
not take into account, or give any effect to, the impact of the proposed transactions with LabCorp. For additional details regarding the Merger Agreement and the tender offer, please see the Companys Current Report on Form 8-K, filed with
the SEC on April 6, 2011, and the Companys Solicitation/Recommendation Statement on Schedule 14D-9 relating to the tender offer, including amendments on Schedule 14D-9/A, filed with the SEC.

(13) Legal Proceedings

On or about November 21, 2001, a complaint was filed in the United States District Court for the Southern District of New York naming
the Company as a defendant, along with certain of the Companys former officers and underwriters. An amended complaint was filed on April 19, 2002. The complaint, as amended, purportedly was filed on behalf of persons purchasing the
Companys stock between May 4, 2000 and December 6, 2000, and alleges violations of Sections 11, 12(a)(2) and 15 of the Securities Act of 1933, as amended, and Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as
amended, and Rule 10b-5 promulgated thereunder. The amended complaint alleges that, in connection with the Companys May 5, 2000 initial public offering, or IPO, the defendants failed to disclose additional and excessive commissions
purportedly solicited by and paid to the underwriter defendants in exchange for allocating shares of our stock to preferred customers and alleged agreements among the underwriter defendants and preferred customers tying the allocation of IPO shares
to agreements to make additional aftermarket purchases at pre-determined prices. Plaintiffs claim that the failure to disclose these alleged arrangements made our registration statement on Form S-1 filed with the SEC in May 2000 and the prospectus,
a part of the registration statement, materially false and misleading. On or about July 15, 2002, the Company filed a motion to dismiss all of the claims against the Company and the Companys former officers. On October 9, 2002, the
Court dismissed without prejudice only the Companys former officers, Dale R. Pfost and Donald R. Marvin, from the litigation in exchange for the Company entering into a tolling agreement with plaintiffs executive committee. On
February 19, 2003, the Company received notice of the Courts decision to dismiss the Section 10(b) claims against the Company. Plaintiffs and the defendant issuers involved in related IPO securities litigation, including us, have
agreed in principal on a settlement that, upon a one-time surety payment by the defendant issuers insurers, would release the defendant issuers and the individual officers and directors from claims and any future payments or out-of-pocket
costs. On March 10, 2005, the Court issued a memorandum and order (i) preliminarily approving the settlement, contingent on the parties agreement on modifications of the proposed bar order in the settlement documents,
(ii) certifying the parties proposed settlement classes, (iii) certifying the proposed class representatives for the purposes of the settlement only and (iv) setting a further hearing for the purposes of (a) making a final
determination as to the form, substance and program of notice of proposed settlement and (b) scheduling a public fairness hearing in order to determine whether the settlement can be finally approved by the Court. On April 24, 2006, the
Court held a fairness hearing and took the motion for final approval under advisement. On October 5, 2009, the Court granted the plaintiffs motion for an order of final approval of the settlement, plan of allocation and certification of
the class. Such settlement does not require any payment by the Company to the plaintiffs. The defendant issuers share of the settlement amount is funded by the insurers. Notices of appeal have been filed by six groups of appellants. None of
the notices state the basis for appeal.

In related proceedings against the underwriters, the United States Court of Appeals
for the Second Circuit ruled on December 5, 2006 that the certification by the District Court for the Southern District of New York of class actions against the underwriters in six focus cases was vacated and remanded for further
proceedings. In so doing, the Second Circuit ruled that the cases pending on this appeal may not be certified as class actions. On April 6, 2007, the Second Circuit denied the plaintiffs petition for rehearing, and no further
appeals have been taken.

As a result of the Second Circuits ruling, the plaintiffs and the issuers stipulated on
June 22, 2007 that the Stipulation and Agreement of Settlement with Defendant Issuers and Individuals, which was originally submitted to the Court on June 10, 2004, was terminated, which resolved the motion for final approval of the class
action settlement with the issuers and individual defendants. The Court entered the parties stipulation as an Order on June 25, 2007. As a result of these developments, the plaintiffs have filed amended complaints against the underwriters
and focus case issuers and individuals and are attempting to certify a class action.

In response to the amended
complaints, the underwriters and focus case issuers moved to dismiss the amended complaints. On March 26, 2008, the motion to dismiss was granted in part and denied in part. As a result, the Court will proceed with the
plaintiffs amended complaints against the underwriters and focus case issuers to determine whether class actions can be certified.

The Company is a defendant in litigation pending in the United States District Court for the
Southern District of New York entitled Enzo Biochem, Inc. et al. (Enzo) v. Amersham PLC, et al. (Amersham), filed in October 2002. By their complaint, plaintiffs allege that certain defendants (i) breached their distributorship agreements by
selling certain products for commercial development (which they allege was not authorized), (ii) infringed plaintiffs patents through the sale and use of certain products, and (iii) are liable for unfair competition and tortious
interference with contractual relations. The Company did not have a contractual relationship with plaintiffs, but the Company is alleged to have purchased the product at issue from one of the other defendants. The Company has sold the business unit
that was allegedly engaged in the unlawful conduct. As a result, there is no relevant injunctive relief to be sought from the Company. The complaint seeks damages in an undisclosed amount. Most of the fact discovery in the case has been taken, and a
Markman hearing to construe the patent claims was conducted in early July 2005. On July 17, 2006, the Court ruled in the Companys favor on the construction of the patents asserted against the Company, and the co-defendants, including the
Company, moved for summary judgment on all claims against us in January 2007. A hearing on the defendants motions for summary judgment occurred on July 17-18, 2007, and the Court reserved ruling on the motions, taking them under
advisement. Such matter has been delayed due to the death of the judge and the assignment of a new judge.

In other litigation
brought by Enzo against another defendant under the same patents asserted against the Company, a Connecticut Federal Court has invalidated the patents asserted there and asserted against the Company in the New York case. That decision was
reversed in part by the Court of Appeals on March 26, 2010. As a result of these developments, the Enzo v. Amersham case has been stayed pending the outcome of the Connecticut Federal Court case.

On February 12, 2010, a complaint was filed in the United States District Court for the Western District of Wisconsin by Genetic
Technologies Limited naming the Company as a defendant, along with eight other companies. The complaint, entitled Genetic Technologies Limited v. Beckman Coulter, Inc., et al., alleges that the defendants infringed U.S. Patent No. 5,612,179
through the sale and use of certain products and services. On March 31, 2011, the Company and Genetic Technologies Limited executed a Settlement Agreement pursuant to which: (i) the Company paid Genetic Technologies Limited $750,000 in
settlement of all claims without either of the parties admitting or denying the allegations raised in the suit; and (ii) Genetic Technologies Limited granted the Company a nonexclusive, worldwide, perpetual, irrevocable, royalty-free license
under the patents which were the subject of the litigation.

On April 11, 2011, a putative class action lawsuit was filed
by a single plaintiff in the Superior Court of New Jersey Chancery Division, Mercer County (Docket No. C 000032 11) against the Company, LabCorp, Purchaser and individual members of the Companys Board of Directors. This action, captioned Bruce

and failed to maximize value for the Companys stockholders by agreeing to the Merger Agreement, and (ii) the Company, LabCorp, and Purchaser aided and abetted the individual defendants in the breach of their fiduciary duties. The
plaintiff seeks (i) to enjoin the acquisition of the Company by Purchaser and LabCorp or, in the alternative, to rescind the Merger Agreement to the extent already implemented, (ii) an order requiring the Companys Board of Directors
and LabCorp to disclose all material information related to the Merger Agreement, and (iii) monetary damages in an unspecified amount. The Company believes the allegations described in the complaint are entirely without merit, and the
defendants intend to vigorously defend such action.

On May 2, 2011, a putative class action lawsuit was filed by a single plaintiff in the
United States District Court for the District of New Jersey against the Company, LabCorp, the Purchaser, and individual members of the Companys Board of Directors (Docket No. 3:11-cv-02508-AET). The action, styled Tsatsis v. Orchid
Cellmark, Inc., alleges that: (i) individual members of the Companys Board of Directors violated their fiduciary duties of good faith and loyalty owed to the Companys stockholders by failing to: (a) fully inform themselves
of the Companys market value, (b) act in the interests of equity owners and (c) maximize shareholder value; (ii) individual defendants breached their fiduciary duty through materially inadequate disclosures and material
disclosure omissions; (iii) LabCorp and the Company aided and abetted the individual directors breaches of fiduciary duty because LabCorp obtained sensitive non-public information concerning the Companys operations and thus had the
advantage to acquire the Company at an unfair price; and (iv) defendants violated section 14(e) of the Exchange Act by failing to provide adequate disclosures in the Solicitation/Recommendation Statement dated April 19, 2011, rendering it
materially false and misleading. Plaintiff seeks: (i) to have the Merger Agreement declared unlawful and unenforceable; (ii) to enjoin the defendants from proceeding with the Merger Agreement or consummating the transaction unless and
until the Company adopts and implements a procedure or process, such as an auction, to obtain the highest possible price for the Company; (iii) to rescind, to the extent already implemented, the Merger Agreement or any of the terms thereof; and

defend such action.

On May 11, 2011, the Superior Court of New Jersey Chancery Division stayed the actions filed by the three
shareholders in that court: Bruce Ballard v. Orchid Cellmark, et al. ((Docket No. C 000032 11), Harrison Kletzel v. Orchid Cellmark Inc., et al., (Docket No. L-1083-11), and Betty Greenberg v. Orchid Cellmark, Inc., et al.
(Docket No. L-1099-11), finding that the allegations were substantially similar to those made by the plaintiffs in the three actions filed in the Delaware Court of Chancery where the motion for preliminary injunction was scheduled for argument on
May 12, 2011. Under principles of comity and fairness and in order to avoid duplicative litigation, the Superior Court of New Jersey Chancery Division ordered the three actions pending in that court be stayed until further order of the Court.

On May 12, 2011, the Delaware Court of Chancery denied the motion for a preliminary injunction filed in the consolidated
Silverberg, Nannetti, and Locke actions finding there was no reasonable likelihood of success on the plaintiffs claims for breach of fiduciary duty by the individual directors of Orchids Board of Directors and thus
no attendant likelihood of success on the plaintiffs claims for aiding and abetting a breach of fiduciary duty by Orchid, LabCorp, and the Purchaser. On May 13, 2011, the plaintiffs in these actions filed a motion to appeal, on an expedited
basis, the denial of their motion for a preliminary injunction.

On May 12, 2011, a motion for preliminary injunction was
filed in the United States District Court of New Jersey in Tsatsis v. Orchid Cellmark, Inc., (Docket No. 3:11-cv-02508-AET-LHG), seeking to enjoin the defendants from proceeding with the Merger Agreement or consummating the transaction
contemplated thereby.

Additionally, the Company has certain other claims against it arising from the normal course of its
business. The ultimate resolution of such matters, including those cases disclosed above, in the opinion of management, will not have a material effect on the Companys financial position and liquidity, but could have a material impact on its
results of operations for any reporting period.

In accordance with ASC 855-10, the Company has evaluated subsequent events through the date these consolidated financial statements were
issued.

Item 2. MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

This Managements Discussion and Analysis of Financial Condition and Results of Operations
as of March 31, 2011 and for the three months ended March 31, 2011 and 2010 should be read in conjunction with our unaudited Consolidated Financial Statements and related unaudited Notes to Consolidated Financial Statements included
elsewhere in this Quarterly Report on Form 10-Q.

OVERVIEW

We are engaged in the provision of DNA testing services that generate genetic profile information by analyzing an organisms unique
genetic identity. We focus our business on DNA testing primarily for human identity and, to a lesser extent, agricultural and other applications. In the human identity area, we principally provide DNA testing services for forensic, family
relationship and, to a lesser extent, security applications. Forensic DNA testing is primarily used to confirm that a suspect committed a particular crime, to exonerate an innocent person or to establish or maintain databases of individuals
convicted of crimes or, in some instances, arrested in connection with crimes. We are also engaged in the provision of non-DNA forensic laboratory services. Family relationship DNA testing is used to establish whether two or more people are
genetically related. DNA testing is used by individuals and employers in security applications to establish or store a persons genetic profile for identification purposes in the event of an emergency or accident. In agricultural applications,
we provide DNA testing services for selective trait breeding.

We have operations in the United States, or US, and in the
United Kingdom, or UK, and the majority of our current customers are based in these two countries. Our forensic, family relationship and security DNA testing services are conducted in both the US and the UK, while all of our agricultural DNA testing
services are conducted in the UK. Based on our review of publicly available information regarding contract sizes and competitor activity, supplemented by industry publications and third-party market assessment data, we believe that the US and UK are
two of the largest existing markets for DNA testing services today. In the US and UK, a significant amount of our current testing activity is under established non-exclusive contracts with government agencies. These contracts are usually awarded
through a sealed bid process and, when awarded, typically have a term from one to three years. We believe that our experience and reputation as a reliable provider of services to government agencies is a valued credential that can be used in
securing both new contracts and renewing existing contracts.

Our operations in the UK accounted for 66% and 60% of our total
revenues for the three months ended March 31, 2011 and 2010, respectively. In 2007, UK police forces commenced soliciting competitive bids for all forensic testing services in a series of regional tenders. In February 2008, we were awarded,
overall, a significant portion of the service packages we bid on in the North West/South West and Wales regional tender. We were awarded work from nine of the fourteen police forces that participated in this tender. Under the terms of the award, we
are providing forensic services, including DNA testing of database crime scene samples, forensic casework and database testing services under the UKs Police and Criminal Evidence Act, or PACE, for multiple police forces that collectively
tendered their work. In August 2010, such contracts were extended for a two-year term ending in 2013. In October 2010, we commenced work for five additional UK police forces in the East Midlands region under three-year contracts awarded under the
National Forensic Procurement Project. Under the terms of the award, we are conducting DNA analysis of crime scene samples for submission to the UKs National DNA Database.

Our operations in the US accounted for 34% and 40% of our total revenues for the three months ended March 31, 2011 and 2010,
respectively. We continue to experience price competition in our forensics and paternity testing businesses. We are focused on improving our operational execution to increase throughput in our laboratories and lower aggregate operating costs. In
particular, in our forensics business we have reduced our sample processing time and decreased the number of Combined DNA Index System, or CODIS, samples that need to be retested. In October 2009, we announced a consolidation of our East
Lansing, Michigan paternity testing operations into our Dayton, Ohio facility, which we completed during the quarter ended March 31, 2010. In January 2010, we announced a planned consolidation of our Nashville, Tennessee forensic DNA
testing facility into our Dallas, Texas facility, which we completed in the quarter ended September 30, 2010. We achieved these consolidations within the time frames and range of costs previously disclosed and our operating costs have been
favorably impacted by the consolidation of these testing facilities. We currently are focused on achieving continued operational efficiencies, cost reductions and increased scalability from these consolidations.

Proposed Acquisition by Laboratory Corporation of America Holdings

On April 5, 2011, we entered into an Agreement and Plan of Merger, or Merger Agreement, with Laboratory Corporation of America
Holdings, or LabCorp, and OCM Acquisition Corp., a wholly owned subsidiary of LabCorp, or the Purchaser, pursuant to which LabCorp will acquire us in a two-step transaction. Pursuant to the Merger Agreement, and subject to its terms and conditions,
on April 19, 2011, Purchaser commenced a cash tender offer to purchase all outstanding shares of our Common Stock, including, to the extent outstanding, the Rights issued under the Rights Agreement, dated July 27, 2001, as amended, between
us and American Stock Transfer & Trust Company, as rights agent, at a purchase price of $2.80 per share, net to the seller in cash, without interest thereon and subject to any required tax withholding.

Unless extended, the tender offer is currently scheduled to expire at 5:00 p.m., New York City time, on Tuesday, May 17, 2011, after
which time, if all conditions to the tender offer have been satisfied or waived, Purchaser will accept for payment all shares of our Common Stock validly tendered pursuant to the offer and not validly withdrawn. If successful, the tender offer will
be followed by the merger of Purchaser into us, with our company being the surviving corporation and becoming a wholly owned subsidiary of LabCorp. In the merger, shares of our Common Stock not purchased in the tender offer (other than shares of our
Common Stock held by stockholders who properly demand and perfect their appraisal rights under Delaware law) will be converted into the right to receive the same $2.80 per share cash payment, without interest, paid in the tender offer.

In addition, the Merger Agreement includes termination provisions for both us and LabCorp and provides that, in connection with the
termination of the Merger Agreement under certain circumstances, we would be obligated to pay LabCorp a termination fee of $2.5 million and reimburse LabCorp for certain out-of-pocket expenses up to $0.5 million. The consummation of the tender offer
and the merger are subject to conditions, including the Purchasers acquisition of a majority of the outstanding shares of our Common Stock on a fully-diluted basis. Neither the tender offer nor the merger is subject to a financing condition.
We can provide no assurance that these transactions will be completed. Except where explicitly stated otherwise, information contained in this report does not take into account, or give any effect to, the impact of the proposed transactions with
LabCorp. For additional details regarding the Merger Agreement and the tender offer, please see our Current Report on Form 8-K, filed with the Securities and Exchange Commission, or the SEC, on April 6, 2011, and our
Solicitation/Recommendation Statement on Schedule 14D-9 relating to the tender offer, including amendments on Schedule 14D-9/A, filed with the SEC.

Operating Highlights

Our revenues are predominately generated from DNA
testing services provided to our customers. Our costs and expenses include costs of service revenues, research and development expenses, marketing and sales expenses, general and administrative expenses, amortization expense and other income and
expense. Costs of service revenues consist primarily of salaries and related personnel costs, laboratory supplies, fees paid for the collection of samples, depreciation and facility expenses. Research and development expenses consist primarily of
salaries and related costs, laboratory supplies and other expenses related to the design, development, testing and enhancement of our services. Marketing and sales expenses consist of salaries and benefits for marketing and sales personnel within
our organization and all related costs of selling and marketing our services. General and administrative expenses consist primarily of salaries and related expenses for executive, finance and administrative personnel, professional fees including
legal expenses, insurance and other corporate expenses.

For the three months ended March 31, 2011, as compared to the
three months ended March 31, 2010, total revenues increased approximately 18%, and gross margin, as percentage of service revenues, decreased by two percentage points to approximately 32%. For the three months ended March 31, 2011 as
compared to the same period in 2010, our UK revenues increased by approximately 28% as measured in US dollars, primarily as a result of increased forensics revenues due to increased volume as well as increased paternity and agriculture revenues. For
the three months ended March 31, 2011, as compared to the three months ended March 31, 2010, our US revenues were relatively unchanged. In the first quarter of 2011, our US revenues were impacted by a significant increase in revenues from
testing services involving DNA profile uploads into the CODIS and individual state databases and an increase in revenues from government and private paternity testing services, and to a lesser extent, an increase in government and private paternity
testing services, offset in part by a decrease in our forensic casework business. Gross margin, as a percentage of service revenue decreased primarily as a result of price decreases in our US-based business, partially offset by higher forensic
volume in our UK operations. For the three months ended March 31, 2011, our operating

expenses, other than cost of service revenues, increased by approximately 10% as compared to the same period in 2010, primarily as a result of increased general and administrative expenses,
primarily related to the $750 thousand incurred to settle the litigation with Genetic Technologies Limited, as well as other legal and professional fees incurred in connection with the negotiation and execution of the Merger Agreement, and sales and
marketing expenses. This increase was partially offset by decreased restructuring expenses as well as decreased research and development expenses.

RESULTS OF OPERATIONS

The following table sets forth a quarter-over-quarter
comparison of the components of our net loss for the three months ended March 31, 2011 and 2010:

Revenues

Total revenues for the three months ended March 31, 2011 of $16.6 million represented an increase of $2.5 million, or approximately
18%, as compared to revenues of $14.1 million for the comparable period in 2010.

Revenues from our UK-based testing services
of $11.0 million for the three months ended March 31, 2011 increased by $2.4 million, or approximately 28%, as compared to $8.5 million for the comparable period in 2010. For the three months ended March 31, 2011, as compared to the
comparable period in 2010, our UK revenues were favorably impacted by approximately 3% as a result of the exchange rate movement of the British pound as compared to the US dollar. Our UK-based revenue increase was driven by a significant increase in
forensics revenues, as well as increases in our paternity and immigration businesses.

Our US service revenues for the three
months ended March 31, 2011 of $5.6 million increased by approximately 1%, as compared to $5.6 million for the comparable period in 2010.In the first quarter of 2011, our US revenues were impacted by a significant increase in CODIS and
individual state database testing services, and to a lesser extent, an increase in government and private paternity testing services, offset by a decrease in our forensic casework testing services due in part to budgetary constraints at the state
and local levels.

During the three months ended March 31, 2011 and 2010, we recognized $7 thousand and $14 thousand,
respectively, in other revenues, specifically license revenues.

Cost of Service Revenues

Cost of service revenues were $11.3 million, or approximately 68% of service revenues, for the three months ended March 31, 2011,
compared to $9.4 million, or approximately 66% of service revenues, for three months ended March 31, 2010. For three months ended March 31, 2011, as compared to the comparable period in 2010, our UK cost of service revenues were
unfavorably impacted by approximately 3% as a result of the exchange rate movement of the British pound as compared to the US dollar. Cost of service revenues for the three months ended March 31, 2011, as compared to the comparable period in
2010, increased due to higher personnel and lab supplies as a result of increased volume in our UK operations. Our gross margin percentage decreased by two percentage points primarily as a result of price and volume decreases in our US-based testing
services as well as price decreases in our UK operations. In October 2009, we announced a consolidation of our East Lansing, Michigan paternity testing operations into our Dayton, Ohio facility, which we completed during the quarter ended
March 31, 2010. In January 2010, we announced a planned consolidation of our Nashville, Tennessee forensic DNA testing facility into our Dallas, Texas facility, which we

##### Table of Contents

completed in the quarter ended September 30, 2010. We achieved these consolidations within the time frames and range of costs previously disclosed and our operating costs have been favorably
impacted by the consolidation of these testing facilities. We currently are focused on achieving continued operational efficiencies, cost reductions and increased scalability from these consolidations.

Research and Development

Research and development expenses for the three months ended March 31, 2011 and 2010 were $364 thousand and $397 thousand, respectively. This decrease was primarily due to costs incurred in the 2010
period associated with the establishment of a CODIS laboratory at our Dallas, Texas testing facility.

Marketing and Sales

Marketing and sales expenses for the three months ended March 31, 2011 and 2010 were $1.6 million and $1.3
million, respectively. The increase in marketing and sales expenses was due to increased program costs in the US and increased customer service expenses in the UK.

General and Administrative

General and administrative expenses for
the three months ended March 31, 2011 and 2010 were $4.7 million and $3.8 million, respectively. The increase in general and administrative expenses is primarily due to the $750 thousand to settle the litigation with Genetic Technologies
Limited and other legal and professional fees, including legal fees incurred in connection with the negotiation and execution of the Merger Agreement. We expect general and administrative costs to increase over the next few months as a result of the
increase in costs incurred in connection with our proposed acquisition by LabCorp, including defending the lawsuits filed against us in connection with the proposed acquisition.

Restructuring

During the three months ended March 31, 2011, we
did not recognize any restructuring expenses related to the consolidation of our East Lansing, Michigan paternity testing operations into our Dayton, Ohio facility and the consolidation of our Nashville, Tennessee testing operation into our Dallas,
Texas facility, as compared to $444 thousand of restructuring expenses recognized in the three months ended March 31, 2010. We announced the planned East Lansing consolidation on October 20, 2009 and substantially completed this
consolidation during the quarter ended March 31, 2010. We announced the planned Nashville consolidation on January 14, 2010, and substantially completed this consolidation during the quarter ended September 30, 2010.

Amortization of Intangible Assets

During the three months ended March 31, 2011 and 2010, we recorded $364 thousand and $463 thousand of amortization expense, respectively.

Income Tax Expense

During the three months ended March 31,
2011 and 2010, we recorded income tax expense of $471 thousand and $404 thousand, respectively, primarily related to our UK business. No tax benefit was recorded relating to our US business losses as management deemed that it was not likely
that such tax benefit would be realized.

Net Loss

For the three months ended March 31, 2011, we reported a net loss of $2.2 million, which represents an increase of $142 thousand compared to a net loss of $2.0 million for the three months ended
March 31, 2010.

LIQUIDITY AND CAPITAL RESOURCES

As of March 31, 2011, we had $17.3 million in cash, cash equivalents and available-for-sale securities, as compared to $19.8 million as of December 31, 2010. Working capital decreased to $20.8
million at March 31, 2011 from $22.2 million at December 31, 2010. The decrease in cash was primarily a result of the $750 thousand settlement of the litigation with Genetic Technologies Limited, an increase in our accounts receivable, as
well as the increased net loss incurred during the first quarter of 2011.

Sources of Liquidity

Our primary sources of liquidity have been issuances of our securities and other capital raising activities.

The following table sets forth a comparison of the components of our liquidity and capital resources for the three months ended March 31, 2011 and 2010:



|                            |  |                |        |   |          |   |        |          |  |   |        |   |  |  |        |

Net cash used in
operations for the three months ended March 31, 2011 was $2.3 million, compared with net cash provided by operations of $3.0 million for the comparable period in the prior year. The change in operating cash flows was mainly a result of the
increased net loss as well as increased accounts receivable in the first quarter of 2011. Investing activities during the three months ended March 31, 2011 consisted of the maturity of available-for-sale securities and investing activities
during the three months ended March 31, 2010 consisted of the purchase of available-for-sale securities, as well as capital expenditures. Financing activities for the first quarter of 2011 consisted of stock options exercised. There was $44
thousand in financing activities, consisting of proceeds from stock options for the first quarter of 2011.

Expected Uses of Liquidity in
2011

Throughout 2011, we plan to continue making investments in our business. We expect the following to be significant
uses of liquidity: cost of service revenues, salaries and related personnel costs, laboratory supplies, fees for the collection of samples, facility expenses, marketing expenses and general and administrative costs, including any increases thereto
resulting from the acquisition by LabCorp and the related litigation. Actual expenditures may vary substantially from our estimates. We expect to make capital expenditures related to the expansion of our UK facilities in Abingdon and Chorley. In
addition, we may make additional investments in future acquisitions of businesses or technologies which would increase our capital expenditures.

We believe that our existing cash on hand will be sufficient to fund our operations at least through the next twelve months. We may need to raise additional capital through debt or equity financing to
fund future growth opportunities or to operate our ongoing business activities if our future results of operations fall below our expectations. However, we may not be able to raise additional funds or raise funds on terms that are acceptable to us.
If future financing is not available to us, or is not available on terms acceptable to us, we may not be able to fund our future needs. If we raise funds through equity or convertible securities, our stockholders may experience dilution and our
stock price may decline.

We cannot assure you that our business or operations will not change in a manner that would consume
available resources more rapidly than anticipated. We also cannot assure you that we will not require substantial additional funding before we can achieve profitable operations. We also may need additional capital if we seek to acquire other
businesses or technologies.

Commitments and Contingencies

There were no material changes during the three months ended March 31, 2011 to our contractual obligations and commercial commitments as reported in the Annual Report for the year ended
December 31, 2010, as amended, as filed with the SEC, or the Annual Report.

Off-Balance Sheet Arrangements

None.

##### Table of Contents

Critical Accounting Policies

There were no changes during the three months ended March 31, 2011 to our critical accounting policies as reported in our Annual Report.

Recently Issued Accounting Pronouncements

There have been no recent
accounting pronouncements or changes in accounting pronouncements during the three months ended March 31, 2011, as compared to the recent accounting pronouncements described in the Annual Report, that are of significance, or potential
significance to the us.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Sensitivity

Our exposure to market risk is principally confined to our cash equivalents, which are conservative in nature, with a focus on preservation of capital. Due to the short-term nature of our investments and
our investment policies and procedures, we have determined that the risks associated with interest rate fluctuations related to these financial instruments are not material to our business. As of March 31, 2011, we had no short-term or
long-term debt obligations.

Foreign Currency Risk

Our business derives a substantial portion of its revenues from international operations. We record the majority of our foreign operational transactions, including all cash inflows and outflows, in the
local currency, British pound. We record all of our US operational transactions, including cash inflows and outflows, in US dollars. We expect that international sales will continue to represent a significant portion of our revenues. The significant
percentage of our revenues derived from our UK operations makes us vulnerable to future fluctuations in the exchange rate. However, all of our operating expenses related to our UK operations also are subject to exchange rate fluctuations and thus
provide a natural hedge against such exchange rate movements. Currently, there is no material adverse impact to our financial results from exchange rate movements.

Item 4. CONTROLS AND PROCEDURES

(a)
Disclosure Controls and Procedures. As of March 31, 2011, we conducted an evaluation under the supervision and with the participation of our management, including our President and Chief Executive Officer and Vice President and Chief
Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. The term disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of
1934, as amended, or the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by the company in the reports it files or submits under the Exchange Act is recorded,
processed, summarized and reported, within the time periods specified in the SECs rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be
disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the companys management, including its principal executive and principal financial officers, or persons performing similar
functions, as appropriate, to allow timely decisions regarding required disclosure. Based on this evaluation, our President and Chief Executive Officer and Vice President and Chief Financial Officer concluded as of March 31, 2011 that our
disclosure controls and procedures were adequate and effective.

(b) Changes in Internal Control over Financial
Reporting. There were no changes in our internal control over financial reporting during the quarter ended March 31, 2011 that have materially affected, or are reasonably likely to materially affect, our internal control over financial
reporting.

(c) Limitations on the Effectiveness of Controls. Our disclosure controls and procedures are
designed to provide reasonable assurance of achieving their objectives and our President and Chief Executive Officer and Vice President and Chief Financial Officer have concluded that our disclosure controls and procedures are adequate and effective
at that reasonable assurance level. However, our management, including our President and Chief Executive Officer and Vice President and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over
financial reporting will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further,

the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent
limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within an organization have been detected. These inherent limitations include the realities that
judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake.

Additionally,
controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the
likelihood of future events, and there can be no assurance that any design will succeed in achieving our stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of
compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements. Such statements are based on managements current expectations and are subject to a number of factors and uncertainties that
could cause actual results or outcomes to differ materially from those described in such forward-looking statements. These statements address or may address the following subjects:



| |  |  | our belief that our experience and reputation as a reliable provider of services to government agencies is a valued credential that can be used in
securing both new contracts and renewing existing contracts;

| |  |  | our belief that the US and UK are some of the largest existing markets for DNA testing services today;
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | our anticipation that our existing cash on hand will be sufficient to fund our operations at least through the next twelve months;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------

liquidity, but could have a material impact on our results of operations for any reporting period;

| |  |  | our plan to continue to make investments in our business;
| | - |  | ---------------------------------------------------------

merit, and that the defendants intend to vigorously defend each action;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our expectation that general and administrative costs will increase over the next few months as a result of the increase in costs incurred in
connection with our proposed acquisition by LabCorp, including defending the lawsuits filed against us in connection with the proposed acquisition;

statements are subject to risks and uncertainties that could cause actual results to vary materially, including the risks and uncertainties discussed throughout this Quarterly Report on Form 10-Q and the cautionary information set forth under the
heading Risk Factors appearing in Item 1A of the Annual Report. Except as required by law, we undertake no obligation to publicly update or revise forward-looking statements to reflect events or circumstances after the date of this
Quarterly Report on Form 10-Q or to reflect the occurrence of unanticipated events.

PART II  OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS

On or about November 21, 2001, a complaint was filed in the United States District Court for the Southern District of New York naming us as a defendant, along with certain of our former officers and
underwriters. An amended complaint was filed on April 19, 2002. The complaint, as amended, purportedly was filed on behalf of persons purchasing our stock between May 4, 2000 and December 6, 2000, and alleges violations of Sections
11, 12(a)(2) and 15 of the Securities Act of 1933, as amended, and Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder. The amended complaint alleges that, in connection with the our
May 5, 2000 initial public offering, or IPO, the defendants failed to disclose additional and excessive commissions purportedly solicited by and paid to the underwriter defendants in exchange for allocating shares of our stock to preferred
customers and alleged agreements among the underwriter defendants and preferred customers tying the allocation of IPO shares to agreements to make additional aftermarket purchases at pre-determined prices. Plaintiffs claim that the failure to
disclose these alleged arrangements made our registration statement on Form S-1 filed with the SEC in May 2000 and the prospectus, a part of the registration statement, materially false and misleading. On or about July 15, 2002, we filed a
motion to dismiss all of the claims against us and our former officers. On October 9, 2002, the Court dismissed without prejudice only our former officers, Dale R. Pfost and Donald R. Marvin, from the litigation in exchange for our entering
into a tolling agreement with plaintiffs executive committee. On February 19, 2003, we received notice of the Courts decision to dismiss the Section 10(b) claims against us. Plaintiffs and the defendant issuers involved in
related IPO securities litigation, including us, have agreed in principal on a settlement that, upon a one-time surety payment by the defendant issuers insurers, would release the defendant issuers and the individual officers and directors
from claims and any future payments or out-of-pocket costs. On March 10, 2005, the Court issued a memorandum and order (i) preliminarily approving the settlement, contingent on the parties agreement on modifications of the proposed
bar order in the settlement documents, (ii) certifying the parties proposed settlement classes, (iii) certifying the proposed class representatives for the purposes of the settlement only and (iv) setting a further hearing for
the purposes of (a) making a final determination as to the form, substance and program of notice of proposed settlement and (b) scheduling a public fairness hearing in order to determine whether the settlement can be finally approved by
the Court. On April 24, 2006, the Court held a fairness hearing and took the motion for final approval under advisement. On October 5, 2009, the Court granted the plaintiffs motion for an order of final approval of the settlement,
plan of allocation and certification of the class. Such settlement does not require any payment by us to the plaintiffs. The defendant issuers share of the settlement amount is funded by the insurers. Notices of appeal have been filed by six
groups of appellants. None of the notices state the basis for appeal.

In related proceedings against the underwriters, the
United States Court of Appeals for the Second Circuit ruled on December 5, 2006 that the certification by the District Court for the Southern District of New York of class actions against the underwriters in six focus cases was
vacated and remanded for further proceedings. In so doing, the Second Circuit ruled that the cases pending on this appeal may not be certified as class actions. On April 6, 2007, the Second Circuit denied the plaintiffs
petition for rehearing, and no further appeals have been taken.

As a result of the Second Circuits ruling, the
plaintiffs and the issuers stipulated on June 22, 2007 that the Stipulation and Agreement of Settlement with Defendant Issuers and Individuals, which was originally submitted to the Court on June 10, 2004, was terminated, which resolved
the motion for final approval of the class action settlement with the issuers and individual defendants. The Court entered the parties stipulation as an Order on June 25, 2007. As a result of these developments, the plaintiffs have filed
amended complaints against the underwriters and focus case issuers and individuals and are attempting to certify a class action.

In response to the amended complaints, the underwriters and focus case issuers moved to dismiss the amended complaints. On March 26, 2008, the motion to dismiss was granted in part and
denied in part. As a result, the Court will proceed with the plaintiffs amended complaints against the underwriters and focus case issuers to determine whether class actions can be certified.

We are a defendant in litigation pending in the United States District Court for the Southern District of New York entitled Enzo Biochem,
Inc. et al. (Enzo) v. Amersham PLC, et al. (Amersham), filed in October 2002. By their complaint, plaintiffs allege that certain defendants (i) breached their distributorship agreements by selling certain products for commercial development
(which they allege was not authorized), (ii) infringed plaintiffs patents through the sale and use of certain products, and (iii) are liable for unfair competition and tortious interference with contractual relations. We did not have
a contractual relationship with plaintiffs, but we are alleged to have purchased the product at

issue from one of the other defendants. We sold the business unit that was allegedly engaged in the unlawful conduct. As a result, there is no relevant injunctive relief to be sought from us. The
complaint seeks damages in an undisclosed amount. Most of the fact discovery in the case has been taken, and a Markman hearing to construe the patent claims was conducted in early July 2005. On July 17, 2006, the Court ruled in our favor on its
construction of the patents asserted against us, and the co-defendants, including us, moved for summary judgment on all claims against us in January 2007. A hearing on the defendants motions for summary judgment occurred on July 17-18,
2007, and the Court reserved ruling on the motions, taking them under advisement. Such matter has been delayed due to the death of the judge and the assignment of a new judge.

In other litigation brought by Enzo against another defendant under the same patents asserted against us, a Connecticut Federal Court has invalidated the patents asserted there and asserted against
us in the New York case. That decision was reversed in part by the Court of Appeals on March 26, 2010. As a result of these developments, the Enzo v. Amersham case has been stayed pending the outcome of the Connecticut Federal Court
case.

On February 12, 2010, a complaint was filed in the United States District Court for the Western District of
Wisconsin by Genetic Technologies Limited naming us as a defendant, along with eight other companies. The complaint, entitled Genetic Technologies Limited v. Beckman Coulter, Inc., et al., alleges that the defendants infringed U.S. Patent
No. 5,612,179 through the sale and use of certain products and services. On March 31, 2011, we and Genetic Technologies Limited executed a Settlement Agreement pursuant to which: (i) we paid Genetic Technologies Limited $750,000 in
settlement of all claims without either of the parties admitting or denying the allegations raised in the suit; and (ii) Genetic Technologies Limited granted us a nonexclusive, worldwide, perpetual, irrevocable, royalty-free license under the
patents which were the subject of the litigation.

On April 11, 2011, a putative class action lawsuit was filed by a
single plaintiff in the Superior Court of New Jersey Chancery Division, Mercer County (Docket No. C 000032 11) against us, LabCorp, Purchaser and individual members of our Board of Directors. This action, captioned Bruce Ballard v. Orchid Cellmark,
et al., alleges that (i) individual members of our Board of Directors violated their fiduciary duties to our stockholders, including the duties of loyalty, care, candor, and good faith, and failed to maximize value for our stockholders by
agreeing to the Merger Agreement, and (ii) the Company, LabCorp, and Purchaser aided and abetted the individual defendants in the breach of their fiduciary duties. The plaintiff seeks (i) to enjoin the acquisition of us by Purchaser and
LabCorp or, in the alternative, to rescind the Merger Agreement to the extent already implemented, (ii) an order requiring our Board of Directors and LabCorp to disclose all material information related to the Merger Agreement, and
(iii) monetary damages in an unspecified amount. We believe the allegations described in the complaint are entirely without merit, and the defendants intend to vigorously defend such action.

On April 13, 2011, a putative class action lawsuit was filed by a single plaintiff in the Court of Chancery for the State of
Delaware (Case No. 6373-VCN) against us, LabCorp, Purchaser, and individual members of our Board of Directors. The action, styled Herbert Silverberg v. Thomas Bologna, et al., alleges that (i) individual members of our Board of Directors
violated their fiduciary duties of care and loyalty owed to our stockholders by (a) failing to properly value us, (b) failing to maximize our value, (c) agreeing to terms in the Merger Agreement and other terms that favor LabCorp, and
(d) putting LabCorps interests above those of our stockholders; and (ii) LabCorp and Purchaser aided and abetted the individual defendants in the breach of their fiduciary duties. The plaintiff seeks (i) to enjoin the
acquisition of us by Purchaser and LabCorp and the implementation of deal protection devices in the Merger Agreement and deployment of our poison pill, and (ii) monetary damages in an unspecified amount. We believe the allegations described in
the complaint are entirely without merit, and the defendants intend to vigorously defend such action.

On April 18, 2011,
a putative class action lawsuit was filed by a single plaintiff in the Court of Chancery for the State of Delaware (Case No. 6389-VCN) against us, LabCorp, Purchaser, and individual members of our Board of Directors. The action, styled Gene
Nannetti v. Thomas Balogna [sic], et al., alleges that (i) individual members of our Board of Directors violated their fiduciary duties of good faith, independence, and loyalty owed to our stockholders by (a) failing to maximize our value,
(b) failing to properly value us, and (c) ignoring or not protecting against conflicts of interest resulting from their interrelationships or connections with the proposed sale of us, and (ii) we, LabCorp, and Purchaser aided and
abetted the individual defendants in the breach of their fiduciary duties. The plaintiff seeks (i) to enjoin the acquisition of us by Purchaser and LabCorp or, in the alternative, to rescind the sale of us and award plaintiff rescissory
damages, and (ii) an accounting of all profits and any special benefits allegedly improperly received by the defendants in an unspecified amount. We believe the allegations described in the complaint are entirely without merit, and the
defendants intend to vigorously defend such action.

single plaintiff in the Superior Court of New Jersey, Chancery Division in Mercer County (Docket No. L-1083-11) against us, LabCorp, Purchaser, and individual members of our board of directors. The action, captioned Harrison Kletzel v. Orchid
Cellmark Inc., et al., alleges that (i) individual members of our board of directors violated their fiduciary duties of good faith, loyalty, and due care owed to our stockholders by (a) failing to undertake an appropriate evaluation of
our worth as a merger candidate or in liquidation, (b) failing to engage in a meaningful auction process and (c) failing to act independently, and, (ii) we, LabCorp and Purchaser aided and abetted the individual defendants in the

On
April 29, 2011, a putative class action lawsuit was filed by a single plaintiff in the Court of Chancery for the State of Delaware (Case No. 6433-VCN) against us, LabCorp, Purchaser, and individual members of our Board of Directors. The
action, styled Bruce Locke vs. Orchid Cellmark Inc., et al., alleges that (i) certain individual members of our Board of Directors violated their fiduciary duties of good faith, loyalty, fair dealing, due care and candor owed to our
stockholders by (a) failing to secure the best transaction available for our stockholders and (b) agreeing to unreasonable and preclusive deal protection measures that will deter superior offers for us, and (ii) LabCorp aided and
abetted the individual defendants in the breach of their fiduciary duties by, among other things, (a) entering into the Merger Agreement and (b) otherwise rendering substantial assistance to our Board of Directors in connection with the
breaches. The plaintiff seeks (i) to enjoin the acquisition of us by Purchaser and LabCorp, (ii) rescission, to the extent already implemented, of the acquisition of us by Purchaser and LabCorp, or alternatively, the awarding of rescissory

shareholder value; (ii) individual defendants breached their fiduciary duty through materially inadequate disclosures and material disclosure omissions; (iii) we and LabCorp aided and abetted the individual directors breaches of
fiduciary duty because LabCorp obtained sensitive non-public information concerning our operations and thus had the advantage to acquire us at an unfair price; and (iv) defendants violated section 14(e) of the Exchange Act by failing to provide

adequate disclosures in the Solicitation/Recommendation Statement dated April 19, 2011, rendering it materially false and misleading. Plaintiff seeks: (i) to have the Merger Agreement
declared unlawful and unenforceable; (ii) to enjoin the defendants from proceeding with the Merger Agreement or consummating the transaction unless and until we adopt and implement a procedure or process, such as an auction, to obtain the
highest possible price for us; (iii) to rescind, to the extent already implemented, the Merger Agreement or any of the terms thereof; and (iv) monetary damages in an unspecified amount as well as costs, fees, and disbursements, among other
relief. We believe the allegations described in the complaint are entirely without merit, and the defendants intend to vigorously defend such action.

On May 11, 2011, the Superior Court of New Jersey Chancery Division stayed the actions filed by the three shareholders in that court: Bruce Ballard v. Orchid Cellmark, et al. ((Docket No. C 000032
11), Harrison Kletzel v. Orchid Cellmark Inc., et al., (Docket No. L-1083-11), and Betty Greenberg v. Orchid Cellmark, Inc., et al. (Docket No. L-1099-11), finding that the allegations were substantially similar to those made by the
plaintiffs in the three actions filed in the Delaware Court of Chancery where the motion for preliminary injunction was scheduled for argument on May 12, 2011. Under principles of comity and fairness and in order to avoid duplicative litigation, the
Superior Court of New Jersey Chancery Division ordered the three actions pending in that court be stayed until further order of the Court.

On May 12, 2011, the Delaware Court of Chancery denied the motion for a preliminary injunction filed in the consolidated Silverberg, Nannetti, and Locke actions finding there was no
reasonable likelihood of success on the plaintiffs claims for breach of fiduciary duty by the individual directors of our Board of Directors and thus no attendant likelihood of success on the plaintiffs claims for aiding and abetting a
breach of fiduciary duty by us, LabCorp, and the Purchaser. On May 13, 2011, the plaintiffs in these actions filed a motion to appeal, on an expedited basis, the denial of their motion for a preliminary injunction.

On May 12, 2011, a motion for preliminary injunction was filed in the United States District Court of New Jersey in Tsatsis v. Orchid
Cellmark, Inc., (Docket No. 3:11-cv-02508-AET-LHG), seeking to enjoin the defendants from proceeding with the Merger Agreement or consummating the transaction contemplated thereby.

Additionally, we may have certain other claims against us arising from the normal course of our business. The ultimate resolution of such
matters, including those cases disclosed above, in the opinion of management, will not have a material effect on our financial position and liquidity, but could have a material impact on our results of operations for any reporting period.

Item 1A. RISK FACTORS

Except as set forth below, there have not been any material changes to the risk factors disclosed under the heading Risk Factors appearing in Item 1A of the Annual Report.

Our proposed acquisition by LabCorp may cause disruption to our business and, if the proposed transactions do not occur, we will have incurred
significant expenses, may need to pay a termination fee under the Merger Agreement, and our stock price may decline.

On April 5, 2011, we entered into the Merger Agreement with LabCorp and Purchaser, pursuant to which LabCorp will acquire us in a
two-step transaction. Pursuant to the Merger Agreement, and subject to its terms and conditions, on April 19, 2011, Purchaser commenced a cash tender offer to purchase all outstanding shares of our Common Stock, including, to the extent
outstanding, the Rights issued under the Rights Agreement, dated July 27, 2001, as amended, between us and American Stock Transfer & Trust Company, as rights agent, at a purchase price of $2.80 per share, net to the seller in cash,
without interest thereon and subject to any required tax withholding.

Unless extended, the tender offer is currently
scheduled to expire at 5:00 p.m., New York City time, on Tuesday, May 17, 2011, after which time, if all conditions to the tender offer have been satisfied or waived, Purchaser will accept for payment all shares of our Common Stock validly
tendered pursuant to the offer and not validly withdrawn. If successful, the tender offer will be followed by the merger of Purchaser into us, with our company being the surviving corporation and becoming a wholly owned subsidiary of LabCorp. In the
merger, shares of our Common Stock not purchased in the tender offer (other than shares of our Common Stock held by stockholders who properly demand and perfect their appraisal rights under Delaware law) will be converted into the right to receive
the same $2.80 per share cash payment, without interest, paid in the tender offer.

The announcement of the Merger Agreement
may result in a loss of personnel and may disrupt our sales and marketing, research and development and other business activities, which may negatively impact our financial performance. The Merger Agreement generally requires us to operate our
business in the ordinary course pending consummation of the proposed transactions, but it also includes certain contractual restrictions on the conduct of our business that may negatively affect our ability to execute our business strategies and
attain our financial goals. Additionally, the announcement of the proposed transactions may negatively impact our relationships with third parties, including our private and government customers.

The consummation of the tender offer and the merger are subject to conditions, including the Purchasers acquisition of a majority
of the outstanding shares of our Common Stock on a fully diluted basis. We can provide no assurance that these transactions will be completed.

We cannot predict whether the closing conditions for the proposed transactions will be satisfied. As a result, we cannot assure you that the proposed transactions will be completed. If the transactions
are not completed because these conditions are not satisfied or for other reasons, the market price of our Common Stock may decline. In addition, if the proposed transactions do not occur, we will remain liable for considerable related expenses that
we have incurred. In addition, the Merger Agreement contemplates circumstances in which we would be obligated to pay LabCorp a termination fee of $2.5 million and reimburse LabCorp for certain out-of-pocket expenses up to $0.5 million.

For additional details regarding the Merger Agreement and the tender offer, please see our
Current Report on Form 8-K, filed with the SEC on April 6, 2011, and our Solicitation/Recommendation Statement on Schedule 14D-9 relating to the tender offer, including amendments on Schedule 14D-9/A, filed with the SEC.

We may incur substantial costs as a result of litigation and other proceedings resulting from our proposed acquisition by LabCorp.

Since the announcement of our proposed acquisition by LabCorp on April 6, 2011, seven putative class action
lawsuits have been filed against us, the individual members of our Board of Directors, LabCorp and the Purchaser seeking, among other things, monetary damages and to enjoin the proposed transactions. We may be subject to additional actions in the
future. We have only limited amounts of insurance, which may not provide coverage to offset a negative judgment or a settlement payment. We may be unable to obtain additional insurance in the future, or we may be unable to do so on favorable terms.
Our insurers may dispute our claims for coverage. Regardless of merit or eventual outcome of these litigations, such actions can result in:



| |  |  | the diversion of managements time and attention;
| | - |  | -------------------------------------------------



| |  |  | the expenditure of large amounts of cash on legal fees, expenses, and payment of damages or settlement costs;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | injury to our reputation; and
| | - |  | -----------------------------



| |  |  | significant delay in consummation of the tender offer or the inability of us, LabCorp and the Purchaser to complete the transactions contemplated by
the Merger Agreement, the ultimate termination of the Merger Agreement and potential payment by us to LabCorp of a termination fee of $2.5 million and expense reimbursement of up to $0.5 million.
