ARTICLE 4 COVENANTS 4.1 Registration of Warrant Shares. 4.1.1 Demand Registration. At any time following the second anniversary of the Closing Date, if Quest Diagnostics shall notify TriPath in writing that it intends to offer or cause to be offered any Warrant Shares for public sales in accordance with Section 4.2 hereof, TriPath shall, promptly following such notice, use its commercially reasonable efforts to effect the registration of such Warrant Shares on a Registration Statement (as defined in Section 4.1.10 below) on Form S-1 or, if TriPath then meets the eligibility requirements for the use of Form S-3 for the registration of securities in a transaction involving secondary offerings, Form S-3 (or any successor form of Registration Statement promulgated by the SEC that would cover the resale of the Warrant Shares), covering the resale of the Warrant Shares proposed to be offered by Quest Diagnostics; provided, however, that, the reasonably anticipated aggregate price to the public for all Warrant Shares proposed to be sold in such public offering would exceed $1,000,000; and provided further, however, that TriPath shall not be required to effect more than one registration pursuant to this Section 4.1.1 in any twelve (12) month period. If at the time of any request to register Warrant Shares pursuant to this Section 4.1.1, TriPath is engaged or has fixed plans to engage within thirty (30) days of the time of the request in a registered public offering as to which Quest Diagnostics may include Warrant Shares pursuant to Section 4.1.2 or is engaged in any other activity which, in the good faith determination of TriPath's Board of Directors, would be adversely affected by the requested registration to the material detriment of TriPath, then TriPath may at its option direct that such request be delayed for a period not in excess of six (6) months from the effective date of such offering or the date of commencement of such other material activity, as the case may be, such right to delay a request to be exercised by TriPath not more than once in any one (1) year period. Any notification by Quest Diagnostics under this Section 4.1.1 is hereinafter referred to as a "Demand Request." -6- 4.1.2 Incidental Registration. (i) At any time following the second anniversary of the Closing Date, if TriPath proposes to file a Registration Statement with the SEC for a public offering and sale of the securities of TriPath either for its own account or the account of a security holder or holders pursuant to demand registration rights (a "Requesting Security Holder"), it will, prior to such filing, give written notice to Quest Diagnostics of its intention to do so and, upon the written request of Quest Diagnostics given within ten (10) trading days after TriPath provides such notice (which request shall state the intended method of disposition of the Warrant Shares and include only such number of Warrant Shares that TriPath may then sell in accordance with Section 4.2 hereof), TriPath shall use its commercially reasonable efforts to cause all Warrant Shares that TriPath has been requested by Quest Diagnostics to register to be registered under the Securities Act to the extent necessary to permit their sale or other disposition in accordance with the intended methods of distribution specified in the request of Quest Diagnostics; provided, however, that notwithstanding the specified method of distribution, in no circumstance will TriPath be required to effect or participate in any distribution by means of an underwriting and shall do so only in its sole discretion; and provided further, however, that TriPath shall have the right to postpone or withdraw any registration effected pursuant to this Section 4.1.2 at any time before it becomes effective or withdraw, postpone or terminate the offering after it becomes effective without regard to whether Quest Diagnostics has requested TriPath to include Warrant Shares in such registration and without any further obligation to Quest Diagnostics. (ii) In connection with any offering under this Section 4.1.2 involving an underwriting, TriPath shall not be required to include any Warrant Shares in such underwriting unless Quest Diagnostics accepts the terms of the underwriting as agreed upon between TriPath and the underwriters selected by it. If in the opinion of the managing underwriter of an underwritten offering the inclusion in such underwritten distribution of all, or part of, the Warrant Shares would materially and adversely affect such public offering, then TriPath will include in such registration, to the extent of the number that TriPath is so advised can be sold in such offering, (A) first, securities TriPath proposes to sell for its own account, (B) second, securities a Requesting Security Holder proposes to sell (whether through the exercise of demand or incidental registration rights), (C) third, up to the full number of Warrant Shares that TriPath has been requested to register, and (D) fourth, any other securities of TriPath included in such registration by the holders thereof. 4.1.3 Registration Procedures. If and whenever TriPath is required by the provisions of this Section 4.1 to use its commercially reasonable efforts to effect the registration of any of the Warrant Shares under the Securities Act, TriPath shall: (i) prepare and file with the SEC a Registration Statement with respect to such Warrant Shares and use its commercially reasonable efforts to cause that Registration Statement to become and remain effective; (ii) prepare and file with the SEC any amendments and supplements to the Registration Statement and the Prospectus (as defined in Section 4.1.10 below) as may be necessary to keep the Registration Statement effective for a period of not less -7- than ninety (90) days from the effective date (excluding for purposes of calculating the ninety (90) day period any period during which Quest Diagnostics is required to discontinue disposition of the Warrant Shares under Section 4.1.4); cause the Prospectus used in connection therewith to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during the period referred to above in accordance with the intended method or methods of distribution by Quest Diagnostics set forth in such Registration Statement as amended or supplement to the Prospectus used in connection therewith;

and furnish such number of copies of the Prospectus (including each preliminary Prospectus) and any amendments or supplements thereto as Quest Diagnostics may reasonably request in order to facilitate the public sale or other disposition of the Warrant Shares being sold by Quest Diagnostics; (iv) register or qualify the Warrant Shares covered by the Registration Statement under such securities or "blue sky" laws, if any, as may be applicable of such states of the United States in which TriPath proposes to sell the securities of TriPath; provided, however, that TriPath shall not be required in connection with this paragraph (iv) to qualify as a foreign corporation in any jurisdiction; (v) give notice to Quest Diagnostics (i) when the Prospectus or any Prospectus supplement or post-effective amendment has been filed and, with respect to the Registration Statement or any post-effective amendment, when the same has become effective, (ii) of any request by the Commission or any state securities authority with jurisdiction for amendments and supplements to the Registration Statement and Prospectus or for additional information after the Registration Statement has become effective, (iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, (iv) of the issuance by any state securities commission or other regulatory authority with jurisdiction of any order suspending the qualification or exemption from qualification of any of the Warrant Shares under any applicable state securities or "blue sky" laws and (v) of the happening of any event that makes any statement made in the Registration Statement or related Prospectus untrue or that requires the making of any changes in the Registration Statement or Prospectus so that they will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; (vi) upon the occurrence of any event contemplated by Section 4.1.3(v), prepare a supplement or post-effective amendment to the Registration Statement or the related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of the Warrant Shares, the Prospectus will not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading; -8- (vii) use its best efforts to obtain the withdrawal at the earliest possible time of any order suspending or preventing the use of any Prospectus or suspending the effectiveness of the Registration Statement or any amendment or supplement thereto or suspending the qualification of any Shares included in such Registration Statement for sale in any jurisdiction; (viii) cooperate with Quest Diagnostics and the managing underwriters, if any, to facilitate the timely preparation and delivery of certificates representing Warrant Shares to be sold and not bearing any restrictive legends; enable such Warrant Shares to be in such denominations and registered in such names as Quest Diagnostics or the managing underwriters may request at least two (2) trading days prior to any sale of Warrant Shares to the underwriters; and (ix) in connection with any offering under this Section 4.1 involving an underwriting, enter into an underwriting agreement in customary form. 4.1.4 Suspension Period. Upon receipt of a notice under clauses (ii) through (v) of Section 4.1.3(v), Quest Diagnostics will forthwith discontinue disposition of the Warrant Shares pursuant to the Registration Statement until Quest Diagnostics' receipt of copies of the supplemented or amended Prospectus, if any, or until Quest Diagnostics is advised in writing by TriPath that the use of the Prospectus may be resumed and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus, and, if so directed by TriPath, Quest Diagnostics will deliver to TriPath all copies, other than permanent file copies then in Quest Diagnostics' possession, of the Prospectus covering the Warrant Shares current at the time of receipt of such notice. 4.1.5 Registration Expenses. TriPath will bear all expenses incurred in connection with the registration of the Warrant Shares pursuant to this Section 4.1, including without limitation all printing, legal and accounting expenses incurred by TriPath and all registration and filing fees imposed by the SEC, any state securities commission or the Nasdaq Stock Market or, if the common stock of TriPath is not then listed on such market, the principal national securities exchange or national market system on which TriPath Stock is then traded or quoted. Quest Diagnostics will be responsible for any brokerage commissions, underwriter's discounts or commissions and taxes of any kind (including, without limitation, transfer taxes) with respect to any disposition, sale or transfer of the Warrant Shares and for any legal, accounting and other expenses incurred by Quest Diagnostics. 4.1.6 Indemnification. (i) Indemnification by TriPath. TriPath agrees to indemnify and hold harmless, to the full extent permitted by law, Quest Diagnostics and each person who controls Quest Diagnostics within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act (collectively, the "Controlling Persons"), from and against all losses, claims, damages, liabilities and expenses (collectively, the "Damages"), incurred by Quest Diagnostics and any such Controlling Person arising out of or based upon any untrue or alleged untrue statement of material fact contained in a Registration Statement (or any amendment thereto), or any omission or alleged omission to state therein a material fact -9- necessary to make the statements therein in light of the circumstances under which they were made not misleading, or any untrue statement or alleged untrue statement of a material fact contained in any Prospectus (as amended or supplemented if TriPath shall have furnished any amendments or supplements thereto), or any omission or alleged omission to state therein a material fact necessary to make the statements therein in light of the circumstances under which they were made not misleading, except insofar as such Damages arise out of or are based upon any such untrue statement or omission based upon information relating to Quest Diagnostics furnished in writing to TriPath by Quest Diagnostics for use therein; provided, however, that TriPath shall not be liable to Quest Diagnostics under this Section 4.1.6(i) to the extent that any such Damages were caused by the fact that Quest Diagnostics sold the Warrant Shares to a person as to whom it shall be established that there was not sent or given, at or prior to the written confirmation of such sale, a copy of the Prospectus as then amended or supplemented if, and only if (A) TriPath has previously furnished copies of such amended or supplemented Prospectus to Quest Diagnostics and (B) such Damages were caused by any untrue statement or omission or alleged untrue statement or omission contained in the Prospectus so delivered that was corrected in such amended or supplemented Prospectus. (ii) Indemnification by Quest Diagnostics. Quest Diagnostics agrees to indemnify and hold harmless, to the full extent permitted by law, TriPath, its directors and officers and each person, if any, who controls TriPath within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from TriPath to Quest Diagnostics, but only with reference to information relating to Quest Diagnostics furnished in writing to TriPath by Quest Diagnostics for use in the Registration Statement (or any amendment thereto) or any Prospectus (or any amendment or supplement thereto); and Quest Diagnostics shall reimburse TriPath for reasonable legal or other expenses incurred by TriPath in connection with investigating or defending any loss, claim, damage, liability or action giving rise to the Damages incurred by TriPath.

Each party entitled to indemnification under this Section 4.1 (the "Indemnified Party") shall give prompt notice of any claim as to which indemnification may be sought to the party required to provide indemnification (the "Indemnifying Party"), provided that failure to give such notice shall not relieve the Indemnifying Party of its obligations hereunder except to the extent of actual prejudice. The Indemnifying Party shall be entitled to assume the defense of any such claim with counsel reasonably satisfactory to the Indemnified Party. The Indemnified Party may participate in such defense at its own expense, provided that the Indemnifying Party will pay such expense if representation of the Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential differing interests between the Indemnified Party and any other party represented by such counsel in such proceeding. No Indemnifying Party shall, except with the consent of the Indemnified Party, agree to any settlement that does not include a release of the Indemnified Party from all liability in respect of such claim, and the Indemnified Party shall not settle such claim without the prior written consent of the Indemnifying Party. 4.1.7 "Stand-Off" Agreement.

Such agreement shall be in writing in a form containing reasonable and customary provisions satisfactory to TriPath and such underwriter and reasonably satisfactory to Quest Diagnostics. TriPath may impose stop transfer instructions with respect to the Warrant Shares or other securities subject to the foregoing restriction until the end of the stand-off period. Quest Diagnostics' obligations under this Section 4.1.7 shall terminate at such time as all Warrant Shares (a) have been disposed of or sold either in accordance with a Registration Statement covering Warrant Shares, pursuant to Rule 144 under the Securities Act, and/or in any manner to a person or entity that is not entitled to the rights under this Section 4.1 and/or (b) all Warrant Shares not disposed of or sold in accordance with the preceding clause (a) may be sold (1) in any three (3) month period pursuant to Rule 144 under the Securities Act or (2) pursuant to Rule 144(k) under the Securities Act and, in either case under this clause (b) Quest Diagnostics shall have acknowledged in writing that TriPath's obligations under this Section 4.1 shall have terminated. 4.1.8 Information by Quest Diagnostics.

-ii- EXHIBIT A-1 THE SECURITIES REPRESENTED BY THIS CERTIFICATE OR ISSUABLE UPON EXERCISE OR CONVERSION HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR ANY STATE SECURITIES LAW AND MAY NOT BE TRANSFERRED EXCEPT (i) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR (ii) UPON FIRST FURNISHING TO THE COMPANY AN OPINION OF COUNSEL SATISFACTORY TO IT AND ITS COUNSEL THAT SUCH TRANSFER IS NOT IN VIOLATION OF THE REGISTRATION REQUIREMENTS OF THE ACT OR ANY STATE SECURITIES LAW. THE TRANSFER OR EXCHANGE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE OR ISSUABLE UPON EXERCISE OR CONVERSION HEREOF ARE FURTHER RESTRICTED AS DESCRIBED HEREIN AND IN A CERTAIN WARRANT PURCHASE AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED OWNER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE OR ISSUABLE UPON EXERCISE OR CONVERSION HEREOF (OR SUCH OWNER'S PREDECESSOR IN INTEREST). TRIPATH IMAGING, INC. WARRANT TO PURCHASE COMMON STOCK This certifies that, for value received, TriPath Imaging, Inc., a Delaware corporation (the "Holder"), is entitled to subscribe for and purchase 800,000 shares (subject to adjustment from time to time pursuant to the provisions of Section 3 hereof) of Common Stock of Quest Diagnostics Incorporated, Inc., a Delaware corporation (the "Company"), at the initial exercise price of $9.25 per share, subject to adjustment from time to time pursuant to the provisions of Section 3 hereof (the "Warrant Price"), subject to the provisions and upon the terms and conditions hereinafter set forth. As used herein, the term "Common Stock" shall mean the Company's Common Stock, par value $0.01 per share, and any stock or other security into or for which such Common Stock may hereafter be converted or exchanged. This Warrant to purchase Common Stock (this "Warrant") is issued pursuant to that certain Warrant Purchase Agreement dated as of May 1, 2004 (the "Warrant Purchase Agreement"), between the Holder and the Company, reference to which is hereby made for a statement of certain of the terms and conditions relating to this Warrant. The shares of Common Stock issuable upon exercise or conversion of this Warrant are referred to herein as "Warrant Shares." 1. Term of Warrant. The purchase or conversion right represented by this Warrant is exercisable, in whole or in part, at any time during the period beginning on the date hereof and ending at 5:00 p.m. Burlington, North Carolina time on the third anniversary of the date hereof. A-1-1 2. Exercise or Conversion of Warrant. 2.1. Procedure for Exercise. Subject to Section 1 hereof, this Warrant may be exercised by the Holder hereof as to the whole or any lesser number of the Warrant Shares covered hereby, by the surrender of this Warrant (with the election at the end hereof duly executed) to the Company at its main office at 780 Plantation Drive, Burlington, North Carolina (the "Main Office"), or at such other place as may be designated in writing by the Company, together with a certified or bank check payable to the order of the Company (or contemporaneous wire transfer to an account in a bank located in the United States designated for such purpose by the Company) in an amount equal to the Warrant Price multiplied by the number of Warrant Shares for which such Warrants are being exercised or converted. 2.2. Procedure for Conversion. Subject to Section 1 hereof, this Warrant may, in lieu of paying the Warrant Price in cash, be converted by the Holder hereof as to the whole or any lesser number of the Warrant Shares covered hereby, into the number of Warrant Shares calculated pursuant to the following formula by the surrender of this Warrant (with the election at the end hereof duly executed) to the Company at the Main Office: X = Y (A - B) -------- A where X = the number of shares of Common Stock to be issued to the holder; Y = the number of shares of Common Stock subject to this Warrant being surrendered for conversion; A = the fair market value of one share of Common Stock; and B = the Warrant Price As used herein, the "fair market value" of a share of Common Stock shall mean the closing price per share of the Company's Common Stock on the principal national securities exchange on which the Common Stock is then listed or admitted to trading or, if not then listed or admitted to trading on any such exchange, on the Nasdaq National Market, or if not then listed or traded on any such exchange or market, the bid price per share on the Nasdaq Small Cap Market or, in the sole discretion of the Board of Directors of the Company, any other over-the-counter market, including the OTC Bulletin Board, which reports bid and asked or last sale prices and volume of sales, in each case volume-weighted averaged over the last ten (10) consecutive trading days before the day on which notice of exercise duly executed and this Warrant are duly delivered to the Company. If at any time such quotations are not available, the current fair market value of a share of Common Stock shall be the highest price per share that the Company could obtain from a willing buyer (not a then current employee or director) for shares of Common Stock sold by the Company, as determined in good faith by the Board of Directors of the Company, unless the Company shall become subject to a merger acquisition or other consolidation pursuant to which the Company will not be the surviving party, in which case the current fair market value of a share of Common Stock shall be deemed to be the value received by the holders of the Company's Common Stock for each share of Common Stock pursuant to such transaction. 2.3. Certificate for Warrant Shares. As soon as practicable (but in any event within ten (10) days) after each such exercise or conversion of this Warrant, the Company shall issue A-1-2 and deliver to the Holder a certificate or certificates for the Warrant Shares issuable upon such exercise or conversion, registered in the name of the Holder or its designee. The Holder will be deemed for all purposes to be the Holder of the shares of Warrant Shares so purchased as of the first trading day following the date of such exercise. If this Warrant should be exercised or converted in part only, the Company shall, upon surrender of the certificate evidencing this Warrant for cancellation, execute and deliver a new Warrant certificate evidencing the right of the Holder to purchase the balance of the Warrant Shares (or portions thereof) subject to purchase hereunder. 2.4. Taxes. The Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the issue and delivery of any certificate in a name other than that of the Holder, and the Company shall not be required to issue or deliver any such certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 2.5. Fractional Shares. The Company shall not be required to issue fractions of shares of Common Stock or other capital stock of the Company upon the exercise or conversion of this Warrant. If any fraction of a share would be issuable on the exercise or conversion of this Warrant, the Company shall purchase such fraction for an amount in cash equal to the same fraction of the fair market value of such share of Common Stock on the date of exercise or conversion of this Warrant, determined in accordance with Section 2.2 hereof. 3. Adjustments. Subject to the provisions of this Section 3, the Warrant Price in effect and the number of Warrant Shares issuable upon exercise or conversion hereof from time to time shall be subject to adjustment as follows: 3.1. Stock Dividend, Split, Combination and Certain Reclassifications. If the Company shall at any time after the date hereof (i) declare a dividend on the outstanding Common Stock payable in shares of its Common Stock, (ii) subdivide the outstanding Common Stock, (iii) combine the outstanding Common Stock into a smaller number of shares, or (iv) issue any shares of its Common Stock by reclassification in connection with a consolidation or merger in which the Company is the continuing corporation, then, in each such case, the Warrant Price in effect and the number of Warrant Shares issuable upon exercise or conversion hereof at the time of the record date for such dividend or of the effective date of such subdivision, combination or reclassification, shall be proportionately adjusted so that the Holder hereof after such time shall be entitled to receive upon exercise or conversion hereof the aggregate number and kind of shares that such Holder would have owned upon exercise or conversion of this Warrant immediately before such time and been entitled to receive by virtue of such dividend, subdivision, combination or reclassification. 3.2. Readjustment. If an adjustment is made under Section 3.1 and the event to which the adjustment relates does not occur or is rescinded, then any adjustments in the Exercise Price or the number of Warrant Shares that were made in accordance with such section shall be adjusted back to the Exercise Price and the number of Warrant Shares that were in effect immediately before the date of or record date for such event. A-1-3 3.3. Certificate of Adjustment. Whenever there shall be an adjustment as provided in this Section 3, the Company shall within thirty (30) days after such adjustment cause written notice thereof to be sent by registered or certified mail, postage prepaid, to the Holder, at its address set forth in Section 5.3 of the Warrant Purchase Agreement, which notice shall be accompanied by an officer's certificate setting forth the number of Warrant Shares issuable hereunder and the Exercise Price thereof after such adjustment and setting forth a brief statement of the facts requiring such adjustment and the computation thereof. The Company may, but is not obligated to, retain a firm of independent public accountants of recognized national standing (who may be any such firm regularly employed by the Company) to make any computation required under this Section 3, and a certificate signed by such firm shall be conclusive evidence of the correctness of the computation made under this Section 3 absent manifest error. 3.4. Limitations. All calculations under this Section 3 shall be made to the nearest cent or to the nearest one-thousandth of a share, as the case may be. No adjustment in the Exercise Price shall be required if such adjustment is less than $0.05; provided, however, that any adjustments that by reason of this Section 3.4 are not required to be made shall be carried forward and taken into account in any subsequent adjustment. 4. Reorganizations; Reclassifications. 4.1. Reorganizations. In each case of a consolidation with or merger of the Company with or into another corporation (other than a merger or consolidation in which the Company is the surviving or continuing corporation and that does not result in any reclassification of the outstanding shares of Common Stock or the conversion of such outstanding shares of Common Stock into shares of other stock or other securities or property), or in case of any sale, lease or conveyance to another corporation of the property and assets of any nature of the Company as an entirety or substantially as an entirety or in the case of a distribution by the Company of its assets with respect to the Common Stock as a liquidating or partial liquidating dividend (such actions being hereinafter collectively referred to as "Reorganizations"), there shall thereafter be deliverable upon exercise or conversion of this Warrant (in lieu of the number of Warrant Shares theretofore deliverable) the kind and amount of shares of stock or other securities or property to which a holder of the number of Warrant Shares that would otherwise have been deliverable upon the exercise or conversion hereof would have been entitled upon such Reorganization if this Warrant had been exercised or converted in full immediately before such Reorganization. In case of any Reorganization, appropriate adjustment, as determined in good faith by the Board of Directors of the Company, shall be made in the application of the provisions herein set forth with respect to the rights and interests of the Holder so that the provisions set forth herein shall thereafter be applicable, as nearly as possible, in relation to any shares or other property thereafter deliverable upon exercise or conversion of this Warrant. Any such adjustment shall be made by and set forth in a supplemental agreement between the Company, or any successor thereto, and the Holder and shall for all purposes hereof conclusively be deemed to be an appropriate adjustment. The Company will not effect any Reorganization involving another person unless, upon or prior to the consummation thereof, the successor person or the other person involved in the Reorganization will assume by written instrument the obligation to deliver to the Holder such shares of stock, securities, cash or property as in accordance with the foregoing provisions the Holder will be entitled to receive. A-1-4 4.2. Reclassifications. In each case of a reclassification or change of the shares of Common Stock issuable upon exercise or conversion of this Warrant (other than a change in par value or from a specified par value to no par value, or as a result of a subdivision or combination, but including any change in the shares into two or more classes or series of shares), and in each case of any consolidation or merger of another corporation into the Company in which the Company is the continuing corporation and in which there is a reclassification or change (including a change to the right to receive cash or other property) of the shares of Common Stock (other than a change in par value, or from a specified par value to no par value, or as a result of a subdivision or combination, but including any change in the shares into two or more classes or series of shares), the Holder shall have the right thereafter to receive upon exercise or conversion of this Warrant solely the kind and amount of shares of stock and other securities, property, cash, or any combination thereof receivable upon such reclassification, change, consolidation, or merger by a holder of the number of shares of Common Stock for which this Warrant might have been exercised or converted immediately before such reclassification, change, consolidation, or merger. Thereafter, appropriate provision shall be made for adjustments that shall be as nearly equivalent as practicable to the adjustments required by Section 3. 5. Restriction on Transfer of Warrant; Warrant Agent; Legends. 5.1. Restrictions. The Holder may neither sell, transfer, assign (except by operation of law) or otherwise dispose of this Warrant to any other person without the prior, express written consent of the Company or in connection with an assignment of the Warrant Agreement permitted by Section 5.1 thereof. In no event shall this Warrant be transferred other than in its entirety (portions of the Warrant may not be transferred). 5.2. Warrant Agent. The Company may, by written notice to the Holder of this Warrant, appoint an agent for the purpose of issuing securities upon exercise of this Warrant, exchanging or replacing this Warrant, or any of the foregoing, and thereafter any such issuance, exchange, or replacement as the case may be, will be made by and at the office of such agent. 5.3. Legends. The certificate or certificates evidencing the Warrant Shares shall bear the following legend: "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR ANY STATE SECURITIES LAW AND MAY NOT BE TRANSFERRED EXCEPT (i) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR (ii) UPON FIRST FURNISHING TO THE COMPANY AN OPINION OF COUNSEL SATISFACTORY TO IT AND ITS COUNSEL THAT SUCH TRANSFER IS NOT IN VIOLATION OF THE REGISTRATION REQUIREMENTS OF THE ACT OR ANY STATE SECURITIES LAW. THE TRANSFER OR EXCHANGE OF THE SHARES REPRESENTED BY THIS CERTIFICATE ARE FURTHER RESTRICTED AS DESCRIBED IN A CERTAIN WARRANT PURCHASE AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED OWNER OF THE SHARES REPRESENTED BY THIS CERTIFICATE (OR SUCH OWNER'S PREDECESSOR IN INTEREST)" A-1-5 6. Authorized Shares. The Company will not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of the Holder hereof against impairment. Without limiting the generality of the foregoing, the Company will (a) not increase the par value of any shares of Common Stock above the amount payable therefor upon the exercise of this Warrant and the issuance of the Common Stock immediately prior to such increase in par value and (b) take all such action as may be reasonably necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable shares of Common Stock, free and clear of preemptive rights and any liens, claims, encumbrances and restrictions (other than as provided herein) upon the exercise of this Warrant. The Company covenants that all shares of Common Stock issuable upon exercise or conversion of this Warrant shall, upon receipt by the Company of the full payment therefor, be validly issued, fully paid, nonassessable, and free of preemptive rights. 7. Miscellaneous. 7.1. Replacement. Upon receipt of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant (and upon surrender of this Warrant if mutilated), upon issuance of an indemnity bond if required by the Company, and upon reimbursement of the Company's incidental expenses, the Company shall execute and deliver to the Holder hereof a new Warrant of like date, tenor and denomination. 7.2. No Rights as Stockholder. The Holder hereof shall not have, solely on account of such status, any rights of a stockholder of the Company, either at law or in equity, or to any notice of meetings of stockholders or of any other proceedings of the Company, except as provided herein. 7.3. Notice. Any notice given to either party under this Warrant shall be given in accordance with Section 5.3 of the Warrant Purchase Agreement. 7.4. Governing Law. This Warrant shall be construed in accordance with the laws of the State of Delaware applicable to contracts made and performed within such state, without regard to principles of conflicts of law. 7.5. Prior Notice of Certain Events. The Company will deliver (by first class mail postage prepaid) to the Holder of this Warrant written notice at least ten (10) days prior to the occurrence of the following events: (a) the date on which a record is to be taken for the purpose of any dividend, distribution or grant of rights, or, if a record is not to be taken, the date as of which the shareholders of Common Stock of record to be entitled to such dividend, distribution or grant of rights are to be determined; A-1-6 (b) the date on which a record is to be taken for the purpose of determining shareholders of Common Stock entitled to vote on any reclassification, reorganization, consolidation, merger, sale, transfer, dissolution, liquidation, winding up or purchase, retirement or redemption; and (c) the date, if any, as of which holders of record of the Common Stock will be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, reorganization, consolidation, merger, sale, transfer, dissolution, liquidation, winding up, purchase, retirement or redemption.

Subject to Section 1 hereof, this Warrant may be exercised by the Holder hereof as to the whole or any lesser number of the Warrant Shares covered hereby, by the surrender of this Warrant (with the election at the end hereof duly executed) to the Company at its main office at 780 Plantation Drive, Burlington, North Carolina (the "Main Office"), or at such other place as may be designated in writing by the Company, together with a certified or bank check payable to the order of the Company (or contemporaneous wire transfer to an account in a bank located in the United States designated for such purpose by the Company) in an amount equal to the Warrant Price multiplied by the number of Warrant Shares for which such Warrants are being exercised or converted. 9.2. Procedure for Conversion. Subject to Section 1 hereof, this Warrant may, in lieu of paying the Warrant Price in cash, be converted by the Holder hereof as to the whole or any lesser number of the Warrant Shares covered hereby, into the number of Warrant Shares calculated pursuant to the following formula by the surrender of this Warrant (with the election at the end hereof duly executed) to the Company at the Main Office: X = Y (A - B) ----- A where X = the number of shares of Common Stock to be issued to the holder; Y = the number of shares of Common Stock subject to this Warrant being surrendered for conversion; A = the fair market value of one share of Common Stock; and B = the Warrant Price As used herein, the "fair market value" of a share of Common Stock shall mean the closing price per share of the Company's Common Stock on the principal national securities exchange on which the Common Stock is then listed or admitted to trading or, if not then listed or admitted to trading on any such exchange, on the Nasdaq National Market, or if not then listed or traded on any such exchange or market, the bid price per share on the Nasdaq Small Cap Market or, in the sole discretion of the Board of Directors of the Company, any other over-the-counter market, including the OTC Bulletin Board, which reports bid and asked or last sale prices and volume of sales, in each case volume-weighted averaged over the last ten (10) consecutive trading days before the day on which notice of exercise duly executed and this Warrant are duly delivered to the Company. If at any time such quotations are not available, the current fair market value of a share of Common Stock shall be the highest price per share that the Company could obtain from a willing buyer (not a then current employee or director) for shares A-2-2 of Common Stock sold by the Company, as determined in good faith by the Board of Directors of the Company, unless the Company shall become subject to a merger acquisition or other consolidation pursuant to which the Company will not be the surviving party, in which case the current fair market value of a share of Common Stock shall be deemed to be the value received by the holders of the Company's Common Stock for each share of Common Stock pursuant to such transaction. 9.3. Certificate for Warrant Shares. As soon as practicable (but in any event within ten (10) days) after each such exercise or conversion of this Warrant, the Company shall issue and deliver to the Holder a certificate or certificates for the Warrant Shares issuable upon such exercise or conversion, registered in the name of the Holder or its designee. The Holder will be deemed for all purposes to be the Holder of the shares of Warrant Shares so purchased as of the first trading day following the date of such exercise. If this Warrant should be exercised or converted in part only, the Company shall, upon surrender of the certificate evidencing this Warrant for cancellation, execute and deliver a new Warrant certificate evidencing the right of the Holder to purchase the balance of the Warrant Shares (or portions thereof) subject to purchase hereunder. 9.4. Taxes. The Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the issue and delivery of any certificate in a name other than that of the Holder, and the Company shall not be required to issue or deliver any such certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 9.5. Fractional Shares. The Company shall not be required to issue fractions of shares of Common Stock or other capital stock of the Company upon the exercise or conversion of this Warrant. If any fraction of a share would be issuable on the exercise or conversion of this Warrant, the Company shall purchase such fraction for an amount in cash equal to the same fraction of the fair market value of such share of Common Stock on the date of exercise or conversion of this Warrant, determined in accordance with Section 2.2 hereof. 10. Adjustments. Subject to the provisions of this Section 3, the Warrant Price in effect and the number of Warrant Shares issuable upon exercise or conversion hereof from time to time shall be subject to adjustment as follows: 10.1. Stock Dividend, Split, Combination and Certain Reclassifications. If the Company shall at any time after the date hereof (i) declare a dividend on the outstanding Common Stock payable in shares of its Common Stock, (ii) subdivide the outstanding Common Stock, (iii) combine the outstanding Common Stock into a smaller number of shares, or (iv) issue any shares of its Common Stock by reclassification in connection with a consolidation or merger in which the Company is the continuing corporation, then, in each such case, the Warrant Price in effect and the number of Warrant Shares issuable upon exercise or conversion hereof at the time of the record date for such dividend or of the effective date of such subdivision, combination or reclassification, shall be proportionately adjusted so that the Holder hereof after such time shall be entitled to receive upon exercise or conversion hereof the aggregate number and kind of shares that such Holder would have owned upon exercise or conversion of this A-2-3 Warrant immediately before such time and been entitled to receive by virtue of such dividend, subdivision, combination or reclassification. 10.2. Readjustment. If an adjustment is made under Section 3.1 and the event to which the adjustment relates does not occur or is rescinded, then any adjustments in the Exercise Price or the number of Warrant Shares that were made in accordance with such section shall be adjusted back to the Exercise Price and the number of Warrant Shares that were in effect immediately before the date of or record date for such event. 10.3. Certificate of Adjustment. Whenever there shall be an adjustment as provided in this Section 3, the Company shall within thirty (30) days after such adjustment cause written notice thereof to be sent by registered or certified mail, postage prepaid, to the Holder, at its address set forth in Section 5.3 of the Warrant Purchase Agreement, which notice shall be accompanied by an officer's certificate setting forth the number of Warrant Shares issuable hereunder and the Exercise Price thereof after such adjustment and setting forth a brief statement of the facts requiring such adjustment and the computation thereof. The Company may, but is not obligated to, retain a firm of independent public accountants of recognized national standing (who may be any such firm regularly employed by the Company) to make any computation required under this Section 3, and a certificate signed by such firm shall be conclusive evidence of the correctness of the computation made under this Section 3 absent manifest error. 10.4. Limitations. All calculations under this Section 3 shall be made to the nearest cent or to the nearest one-thousandth of a share, as the case may be. No adjustment in the Exercise Price shall be required if such adjustment is less than $0.05; provided, however, that any adjustments that by reason of this Section 3.4 are not required to be made shall be carried forward and taken into account in any subsequent adjustment. 11. Reorganizations; Reclassifications. 11.1. Reorganizations. In each case of a consolidation with or merger of the Company with or into another corporation (other than a merger or consolidation in which the Company is the surviving or continuing corporation and that does not result in any reclassification of the outstanding shares of Common Stock or the conversion of such outstanding shares of Common Stock into shares of other stock or other securities or property), or in case of any sale, lease or conveyance to another corporation of the property and assets of any nature of the Company as an entirety or substantially as an entirety or in the case of a distribution by the Company of its assets with respect to the Common Stock as a liquidating or partial liquidating dividend (such actions being hereinafter collectively referred to as "Reorganizations"), there shall thereafter be deliverable upon exercise or conversion of this Warrant (in lieu of the number of Warrant Shares theretofore deliverable) the kind and amount of shares of stock or other securities or property to which a holder of the number of Warrant Shares that would otherwise have been deliverable upon the exercise or conversion hereof would have been entitled upon such Reorganization if this Warrant had been exercised or converted in full immediately before such Reorganization. In case of any Reorganization, appropriate adjustment, as determined in good faith by the Board of Directors of the Company, shall be made in the application of the provisions herein set forth with respect to the rights and interests of the Holder so that the provisions set forth herein shall thereafter be applicable, as nearly as possible, in relation to any shares or other property A-2-4 thereafter deliverable upon exercise or conversion of this Warrant. Any such adjustment shall be made by and set forth in a supplemental agreement between the Company, or any successor thereto, and the Holder and shall for all purposes hereof conclusively be deemed to be an appropriate adjustment. The Company will not effect any Reorganization involving another person unless, upon or prior to the consummation thereof, the successor person or the other person involved in the Reorganization will assume by written instrument the obligation to deliver to the Holder such shares of stock, securities, cash or property as in accordance with the foregoing provisions the Holder will be entitled to receive. 11.2. Reclassifications. In each case of a reclassification or change of the shares of Common Stock issuable upon exercise or conversion of this Warrant (other than a change in par value or from a specified par value to no par value, or as a result of a subdivision or combination, but including any change in the shares into two or more classes or series of shares), and in each case of any consolidation or merger of another corporation into the Company in which the Company is the continuing corporation and in which there is a reclassification or change (including a change to the right to receive cash or other property) of the shares of Common Stock (other than a change in par value, or from a specified par value to no par value, or as a result of a subdivision or combination, but including any change in the shares into two or more classes or series of shares), the Holder shall have the right thereafter to receive upon exercise or conversion of this Warrant solely the kind and amount of shares of stock and other securities, property, cash, or any combination thereof receivable upon such reclassification, change, consolidation, or merger by a holder of the number of shares of Common Stock for which this Warrant might have been exercised or converted immediately before such reclassification, change, consolidation, or merger. Thereafter, appropriate provision shall be made for adjustments that shall be as nearly equivalent as practicable to the adjustments required by Section 3. 12. Restriction on Transfer of Warrant; Warrant Agent; Legends. 12.1. Restrictions. The Holder may neither sell, transfer, assign (except by operation of law) or otherwise dispose of this Warrant to any other person without the prior, express written consent of the Company or in connection with an assignment of the Warrant Agreement permitted by Section 5.1 thereof. In no event shall this Warrant be transferred other than in its entirety (portions of the Warrant may not be transferred). 12.2. Warrant Agent. The Company may, by written notice to the Holder of this Warrant, appoint an agent for the purpose of issuing securities upon exercise of this Warrant, exchanging or replacing this Warrant, or any of the foregoing, and thereafter any such issuance, exchange, or replacement as the case may be, will be made by and at the office of such agent. 12.3. Legends. The certificate or certificates evidencing the Warrant Shares shall bear the following legend: "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR ANY STATE SECURITIES LAW AND MAY NOT BE TRANSFERRED EXCEPT (i) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR (ii) UPON FIRST A-2-5 FURNISHING TO THE COMPANY AN OPINION OF COUNSEL SATISFACTORY TO IT AND ITS COUNSEL THAT SUCH TRANSFER IS NOT IN VIOLATION OF THE REGISTRATION REQUIREMENTS OF THE ACT OR ANY STATE SECURITIES LAW.

The Company will not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of the Holder hereof against impairment. Without limiting the generality of the foregoing, the Company will (a) not increase the par value of any shares of Common Stock above the amount payable therefor upon the exercise of this Warrant and the issuance of the Common Stock immediately prior to such increase in par value and (b) take all such action as may be reasonably necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable shares of Common Stock, free and clear of preemptive rights and any liens, claims, encumbrances and restrictions (other than as provided herein) upon the exercise of this Warrant. The Company covenants that all shares of Common Stock issuable upon exercise or conversion of this Warrant shall, upon receipt by the Company of the full payment therefor, be validly issued, fully paid, nonassessable, and free of preemptive rights. 14.

No Rights as Stockholder. The Holder hereof shall not have, solely on account of such status, any rights of a stockholder of the Company, either at law or in equity, or to any notice of meetings of stockholders or of any other proceedings of the Company, except as provided herein. 14.3.

Certificate of Adjustment. Whenever there shall be an adjustment as provided in this Section 3, the Company shall within thirty (30) days after such adjustment cause written notice thereof to be sent by registered or certified mail, postage prepaid, to the Holder, at its address set forth in Section 5.3 of the Warrant Purchase Agreement, which notice shall be accompanied by an officer's certificate setting forth the number of Warrant Shares issuable hereunder and the Exercise Price thereof after such adjustment and setting forth a brief statement of the facts requiring such adjustment and the computation thereof.

In case of any Reorganization, appropriate adjustment, as determined in good faith by the Board of Directors of the Company, shall be made in the application of the provisions herein set forth with respect to the rights and interests of the Holder so that the provisions set forth herein shall thereafter be applicable, as nearly as possible, in relation to any shares or other property A-3 - 4 thereafter deliverable upon exercise or conversion of this Warrant. Any such adjustment shall be made by and set forth in a supplemental agreement between the Company, or any successor thereto, and the Holder and shall for all purposes hereof conclusively be deemed to be an appropriate adjustment. The Company will not effect any Reorganization involving another person unless, upon or prior to the consummation thereof, the successor person or the other person involved in the Reorganization will assume by written instrument the obligation to deliver to the Holder such shares of stock, securities, cash or property as in accordance with the foregoing provisions the Holder will be entitled to receive. 18.2.

Thereafter, appropriate provision shall be made for adjustments that shall be as nearly equivalent as practicable to the adjustments required by Section 3. 19. Restriction on Transfer of Warrant; Warrant Agent; Legends. 19.1. Restrictions. The Holder may neither sell, transfer, assign (except by operation of law) or otherwise dispose of this Warrant to any other person without the prior, express written consent of the Company or in connection with an assignment of the Warrant Agreement permitted by Section 5.1 thereof.

The Company will not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of the Holder hereof against impairment. Without limiting the generality of the foregoing, the Company will (a) not increase the par value of any shares of Common Stock above the amount payable therefor upon the exercise of this Warrant and the issuance of the Common Stock immediately prior to such increase in par value and (b) take all such action as may be reasonably necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable shares of Common Stock, free and clear of preemptive rights and any liens, claims, encumbrances and restrictions (other than as provided herein) upon the exercise of this Warrant.

As used herein, the term "Common Stock" shall mean the Company's Common Stock, par value $0.01 per share, and any stock or other security into or for which such Common Stock may hereafter be converted or exchanged.

The shares of Common Stock issuable upon exercise or conversion of this Warrant are referred to herein as "Warrant Shares." 22. Term of Warrant. The purchase or conversion right represented by this Warrant is exercisable, in whole or in part, at any time during the period beginning on the delivery of the calculation of the Third Milestone Date (as defined in the Warrant Purchase Agreement) and ending at 5:00 p.m. Burlington, North Carolina time on the fourth anniversary of the date hereof; provided, however, if the calculation as to the Third Milestone Date shall be delivered on or after such fourth anniversary, then the purchase or conversion right represented by this Warrant shall A-4 - 1 remain exercisable until 5:00 p.m. Burlington, North Carolina time on the tenth day after delivery of such calculation as to the Third Milestone Date; and provided further, however, that, in the event the Holder contests such calculation within five (5) business days after receipt of such calculation by notice accompanied by reasonable detail concerning such contest, the Holder shall retain the right, exercisable until such tenth day, to deliver this Warrant (with the election at the end hereof duly executed) for exercise, which exercise would be considered effective for all purposes of this Warrant only upon the resolution of the dispute as to such calculation confirming that the applicable milestone has been met. 23. Exercise or Conversion of Warrant. 23.1. Procedure for Exercise. Subject to Section 1 hereof, this Warrant may be exercised by the Holder hereof as to the whole or any lesser number of the Warrant Shares covered hereby, by the surrender of this Warrant (with the election at the end hereof duly executed) to the Company at its main office at 780 Plantation Drive, Burlington, North Carolina (the "Main Office"), or at such other place as may be designated in writing by the Company, together with a certified or bank check payable to the order of the Company (or contemporaneous wire transfer to an account in a bank located in the United States designated for such purpose by the Company) in an amount equal to the Warrant Price multiplied by the number of Warrant Shares for which such Warrants are being exercised or converted. 23.2. Procedure for Conversion. Subject to Section 1 hereof, this Warrant may, in lieu of paying the Warrant Price in cash, be converted by the Holder hereof as to the whole or any lesser number of the Warrant Shares covered hereby, into the number of Warrant Shares calculated pursuant to the following formula by the surrender of this Warrant (with the election at the end hereof duly executed) to the Company at the Main Office: X = Y (A - B) -------- A where X = the number of shares of Common Stock to be issued to the holder; Y = the number of shares of Common Stock subject to this Warrant being surrendered for conversion; A = the fair market value of one share of Common Stock; and B = the Warrant Price As used herein, the "fair market value" of a share of Common Stock shall mean the closing price per share of the Company's Common Stock on the principal national securities exchange on which the Common Stock is then listed or admitted to trading or, if not then listed or admitted to trading on any such exchange, on the Nasdaq National Market, or if not then listed or traded on any such exchange or market, the bid price per share on the Nasdaq Small Cap Market or, in the sole discretion of the Board of Directors of the Company, any other over-the-counter market, including the OTC Bulletin Board, which reports bid and asked or last sale prices and volume of sales, in each case volume-weighted averaged over the last ten (10) consecutive trading days before the day on which notice of exercise duly executed and this Warrant are duly delivered to the Company. If at any time such quotations are not available, the current fair market value of a share of Common Stock shall be the highest price per share that the Company could obtain from a willing buyer (not a then current employee or director) for shares A-4 - 2 of Common Stock sold by the Company, as determined in good faith by the Board of Directors of the Company, unless the Company shall become subject to a merger acquisition or other consolidation pursuant to which the Company will not be the surviving party, in which case the current fair market value of a share of Common Stock shall be deemed to be the value received by the holders of the Company's Common Stock for each share of Common Stock pursuant to such transaction. 23.3. Certificate for Warrant Shares. As soon as practicable (but in any event within ten (10) days) after each such exercise or conversion of this Warrant, the Company shall issue and deliver to the Holder a certificate or certificates for the Warrant Shares issuable upon such exercise or conversion, registered in the name of the Holder or its designee. The Holder will be deemed for all purposes to be the Holder of the shares of Warrant Shares so purchased as of the first trading day following the date of such exercise. If this Warrant should be exercised or converted in part only, the Company shall, upon surrender of the certificate evidencing this Warrant for cancellation, execute and deliver a new Warrant certificate evidencing the right of the Holder to purchase the balance of the Warrant Shares (or portions thereof) subject to purchase hereunder. 23.4. Taxes. The Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the issue and delivery of any certificate in a name other than that of the Holder, and the Company shall not be required to issue or deliver any such certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 23.5. Fractional Shares. The Company shall not be required to issue fractions of shares of Common Stock or other capital stock of the Company upon the exercise or conversion of this Warrant. If any fraction of a share would be issuable on the exercise or conversion of this Warrant, the Company shall purchase such fraction for an amount in cash equal to the same fraction of the fair market value of such share of Common Stock on the date of exercise or conversion of this Warrant, determined in accordance with Section 2.2 hereof. 24. Adjustments. Subject to the provisions of this Section 3, the Warrant Price in effect and the number of Warrant Shares issuable upon exercise or conversion hereof from time to time shall be subject to adjustment as follows: 24.1. Stock Dividend, Split, Combination and Certain Reclassifications. If the Company shall at any time after the date hereof (i) declare a dividend on the outstanding Common Stock payable in shares of its Common Stock, (ii) subdivide the outstanding Common Stock, (iii) combine the outstanding Common Stock into a smaller number of shares, or (iv) issue any shares of its Common Stock by reclassification in connection with a consolidation or merger in which the Company is the continuing corporation, then, in each such case, the Warrant Price in effect and the number of Warrant Shares issuable upon exercise or conversion hereof at the time of the record date for such dividend or of the effective date of such subdivision, combination or reclassification, shall be proportionately adjusted so that the Holder hereof after such time shall be entitled to receive upon exercise or conversion hereof the aggregate number and kind of shares that such Holder would have owned upon exercise or conversion of this A-4 - 3 Warrant immediately before such time and been entitled to receive by virtue of such dividend, subdivision, combination or reclassification. 24.2. Readjustment. If an adjustment is made under Section 3.1 and the event to which the adjustment relates does not occur or is rescinded, then any adjustments in the Exercise Price or the number of Warrant Shares that were made in accordance with such section shall be adjusted back to the Exercise Price and the number of Warrant Shares that were in effect immediately before the date of or record date for such event. 24.3. Certificate of Adjustment. Whenever there shall be an adjustment as provided in this Section 3, the Company shall within thirty (30) days after such adjustment cause written notice thereof to be sent by registered or certified mail, postage prepaid, to the Holder, at its address set forth in Section 5.3 of the Warrant Purchase Agreement, which notice shall be accompanied by an officer's certificate setting forth the number of Warrant Shares issuable hereunder and the Exercise Price thereof after such adjustment and setting forth a brief statement of the facts requiring such adjustment and the computation thereof. The Company may, but is not obligated to, retain a firm of independent public accountants of recognized national standing (who may be any such firm regularly employed by the Company) to make any computation required under this Section 3, and a certificate signed by such firm shall be conclusive evidence of the correctness of the computation made under this Section 3 absent manifest error. 24.4. Limitations. All calculations under this Section 3 shall be made to the nearest cent or to the nearest one-thousandth of a share, as the case may be. No adjustment in the Exercise Price shall be required if such adjustment is less than $0.05; provided, however, that any adjustments that by reason of this Section 3.4 are not required to be made shall be carried forward and taken into account in any subsequent adjustment. 25. Reorganizations; Reclassifications. 25.1. Reorganizations. In each case of a consolidation with or merger of the Company with or into another corporation (other than a merger or consolidation in which the Company is the surviving or continuing corporation and that does not result in any reclassification of the outstanding shares of Common Stock or the conversion of such outstanding shares of Common Stock into shares of other stock or other securities or property), or in case of any sale, lease or conveyance to another corporation of the property and assets of any nature of the Company as an entirety or substantially as an entirety or in the case of a distribution by the Company of its assets with respect to the Common Stock as a liquidating or partial liquidating dividend (such actions being hereinafter collectively referred to as "Reorganizations"), there shall thereafter be deliverable upon exercise or conversion of this Warrant (in lieu of the number of Warrant Shares theretofore deliverable) the kind and amount of shares of stock or other securities or property to which a holder of the number of Warrant Shares that would otherwise have been deliverable upon the exercise or conversion hereof would have been entitled upon such Reorganization if this Warrant had been exercised or converted in full immediately before such Reorganization. In case of any Reorganization, appropriate adjustment, as determined in good faith by the Board of Directors of the Company, shall be made in the application of the provisions herein set forth with respect to the rights and interests of the Holder so that the provisions set forth herein shall thereafter be applicable, as nearly as possible, in relation to any shares or other property A-4 - 4 thereafter deliverable upon exercise or conversion of this Warrant. Any such adjustment shall be made by and set forth in a supplemental agreement between the Company, or any successor thereto, and the Holder and shall for all purposes hereof conclusively be deemed to be an appropriate adjustment. The Company will not effect any Reorganization involving another person unless, upon or prior to the consummation thereof, the successor person or the other person involved in the Reorganization will assume by written instrument the obligation to deliver to the Holder such shares of stock, securities, cash or property as in accordance with the foregoing provisions the Holder will be entitled to receive. 25.2. Reclassifications. In each case of a reclassification or change of the shares of Common Stock issuable upon exercise or conversion of this Warrant (other than a change in par value or from a specified par value to no par value, or as a result of a subdivision or combination, but including any change in the shares into two or more classes or series of shares), and in each case of any consolidation or merger of another corporation into the Company in which the Company is the continuing corporation and in which there is a reclassification or change (including a change to the right to receive cash or other property) of the shares of Common Stock (other than a change in par value, or from a specified par value to no par value, or as a result of a subdivision or combination, but including any change in the shares into two or more classes or series of shares), the Holder shall have the right thereafter to receive upon exercise or conversion of this Warrant solely the kind and amount of shares of stock and other securities, property, cash, or any combination thereof receivable upon such reclassification, change, consolidation, or merger by a holder of the number of shares of Common Stock for which this Warrant might have been exercised or converted immediately before such reclassification, change, consolidation, or merger. Thereafter, appropriate provision shall be made for adjustments that shall be as nearly equivalent as practicable to the adjustments required by Section 3. 26. Restriction on Transfer of Warrant; Warrant Agent; Legends. 26.1. Restrictions. The Holder may neither sell, transfer, assign (except by operation of law) or otherwise dispose of this Warrant to any other person without the prior, express written consent of the Company or in connection with an assignment of the Warrant Agreement permitted by Section 5.1 thereof. In no event shall this Warrant be transferred other than in its entirety (portions of the Warrant may not be transferred). 26.2. Warrant Agent. The Company may, by written notice to the Holder of this Warrant, appoint an agent for the purpose of issuing securities upon exercise of this Warrant, exchanging or replacing this Warrant, or any of the foregoing, and thereafter any such issuance, exchange, or replacement as the case may be, will be made by and at the office of such agent. 26.3. Legends.

Authorized Shares. The Company will not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of the Holder hereof against impairment. Without limiting the generality of the foregoing, the Company will (a) not increase the par value of any shares of Common Stock above the amount payable therefor upon the exercise of this Warrant and the issuance of the Common Stock immediately prior to such increase in par value and (b) take all such action as may be reasonably necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable shares of Common Stock, free and clear of preemptive rights and any liens, claims, encumbrances and restrictions (other than as provided herein) upon the exercise of this Warrant. The Company covenants that all shares of Common Stock issuable upon exercise or conversion of this Warrant shall, upon receipt by the Company of the full payment therefor, be validly issued, fully paid, nonassessable, and free of preemptive rights. 28.

Exercise or Conversion of Warrant. 30.1. Procedure for Exercise. Subject to Section 1 hereof, this Warrant may be exercised by the Holder hereof as to the whole or any lesser number of the Warrant Shares covered hereby, by the surrender of this Warrant (with the election at the end hereof duly executed) to the Company at its main office at 780 Plantation Drive, Burlington, North Carolina (the "Main Office"), or at such other place as may be designated in writing by the Company, together with a certified or bank check payable to the order of the Company (or contemporaneous wire transfer to an account in a bank located in the United States designated for such purpose by the Company) in an amount equal to the Warrant Price multiplied by the number of Warrant Shares for which such Warrants are being exercised or converted. 30.2. Procedure for Conversion. Subject to Section 1 hereof, this Warrant may, in lieu of paying the Warrant Price in cash, be converted by the Holder hereof as to the whole or any lesser number of the Warrant Shares covered hereby, into the number of Warrant Shares calculated pursuant to the following formula by the surrender of this Warrant (with the election at the end hereof duly executed) to the Company at the Main Office: X = Y (A - B) -------- A where X = the number of shares of Common Stock to be issued to the holder; Y = the number of shares of Common Stock subject to this Warrant being surrendered for conversion; A = the fair market value of one share of Common Stock; and B = the Warrant Price As used herein, the "fair market value" of a share of Common Stock shall mean the closing price per share of the Company's Common Stock on the principal national securities exchange on which the Common Stock is then listed or admitted to trading or, if not then listed or admitted to trading on any such exchange, on the Nasdaq National Market, or if not then listed or traded on any such exchange or market, the bid price per share on the Nasdaq Small Cap Market or, in the sole discretion of the Board of Directors of the Company, any other over-the-counter market, including the OTC Bulletin Board, which reports bid and asked or last sale prices and volume of sales, in each case volume-weighted averaged over the last ten (10) consecutive trading days before the day on which notice of exercise duly executed and this Warrant are duly delivered to the Company.

If the Company shall at any time after the date hereof (i) declare a dividend on the outstanding Common Stock payable in shares of its Common Stock, (ii) subdivide the outstanding Common Stock, (iii) combine the outstanding Common Stock into a smaller number of shares, or (iv) issue any shares of its Common Stock by reclassification in connection with a consolidation or merger in which the Company is the continuing corporation, then, in each such case, the Warrant Price in effect and the number of Warrant Shares issuable upon exercise or conversion hereof at the time of the record date for such dividend or of the effective date of such subdivision, combination or reclassification, shall be proportionately adjusted so that the Holder hereof after such time shall be entitled to receive upon exercise or conversion hereof the aggregate number and kind of shares that such Holder would have owned upon exercise or conversion of this A-5 - 3 Warrant immediately before such time and been entitled to receive by virtue of such dividend, subdivision, combination or reclassification. 31.2. Readjustment. If an adjustment is made under Section 3.1 and the event to which the adjustment relates does not occur or is rescinded, then any adjustments in the Exercise Price or the number of Warrant Shares that were made in accordance with such section shall be adjusted back to the Exercise Price and the number of Warrant Shares that were in effect immediately before the date of or record date for such event. 31.3. Certificate of Adjustment. Whenever there shall be an adjustment as provided in this Section 3, the Company shall within thirty (30) days after such adjustment cause written notice thereof to be sent by registered or certified mail, postage prepaid, to the Holder, at its address set forth in Section 5.3 of the Warrant Purchase Agreement, which notice shall be accompanied by an officer's certificate setting forth the number of Warrant Shares issuable hereunder and the Exercise Price thereof after such adjustment and setting forth a brief statement of the facts requiring such adjustment and the computation thereof. The Company may, but is not obligated to, retain a firm of independent public accountants of recognized national standing (who may be any such firm regularly employed by the Company) to make any computation required under this Section 3, and a certificate signed by such firm shall be conclusive evidence of the correctness of the computation made under this Section 3 absent manifest error. 31.4. Limitations. All calculations under this Section 3 shall be made to the nearest cent or to the nearest one-thousandth of a share, as the case may be. No adjustment in the Exercise Price shall be required if such adjustment is less than $0.05; provided, however, that any adjustments that by reason of this Section 3.4 are not required to be made shall be carried forward and taken into account in any subsequent adjustment. 32. Reorganizations; Reclassifications. 32.1. Reorganizations. In each case of a consolidation with or merger of the Company with or into another corporation (other than a merger or consolidation in which the Company is the surviving or continuing corporation and that does not result in any reclassification of the outstanding shares of Common Stock or the conversion of such outstanding shares of Common Stock into shares of other stock or other securities or property), or in case of any sale, lease or conveyance to another corporation of the property and assets of any nature of the Company as an entirety or substantially as an entirety or in the case of a distribution by the Company of its assets with respect to the Common Stock as a liquidating or partial liquidating dividend (such actions being hereinafter collectively referred to as "Reorganizations"), there shall thereafter be deliverable upon exercise or conversion of this Warrant (in lieu of the number of Warrant Shares theretofore deliverable) the kind and amount of shares of stock or other securities or property to which a holder of the number of Warrant Shares that would otherwise have been deliverable upon the exercise or conversion hereof would have been entitled upon such Reorganization if this Warrant had been exercised or converted in full immediately before such Reorganization. In case of any Reorganization, appropriate adjustment, as determined in good faith by the Board of Directors of the Company, shall be made in the application of the provisions herein set forth with respect to the rights and interests of the Holder so that the provisions set forth herein shall thereafter be applicable, as nearly as possible, in relation to any shares or other property A-5 - 4 thereafter deliverable upon exercise or conversion of this Warrant. Any such adjustment shall be made by and set forth in a supplemental agreement between the Company, or any successor thereto, and the Holder and shall for all purposes hereof conclusively be deemed to be an appropriate adjustment.
