HOLOGIC, INC. 2008 EQUITY INCENTIVE PLAN

Exhibit 10.1

HOLOGIC, INC.

2008 EQUITY INCENTIVE PLAN

1. PURPOSE AND ELIGIBILITY.

The purpose of this 2008 Equity Incentive Plan (the “Plan”) of HOLOGIC, INC., a Delaware corporation (the “Company”), is to provide stock options, stock issuances and other equity interests in the Company (each, an “Award”) to (a) employees, officers, directors, consultants and advisors of the Company and its Parents and Subsidiaries, and (b) any other person who is determined by the Board to have made (or is expected to make) contributions to the Company. Any person to whom an Award has been granted under the Plan is called a “Participant.” Additional definitions are contained in Section 11.

2. ADMINISTRATION.

a. Administration by Board of Directors. The Plan will be administered by the Board of Directors of the Company (the “Board”). The Board, in its sole discretion, shall have the authority to grant and amend Awards, to adopt, amend and repeal rules relating to the Plan and to interpret and correct the provisions of the Plan and any Award. The Board shall have authority, subject to the express limitations of the Plan, (i) to construe and determine the respective Stock Option Agreement (as defined below), Awards and the Plan, (ii) to prescribe, amend and rescind rules and regulations relating to the Plan and any Awards, (iii) to determine the terms and provisions of the respective Stock Option Agreements and Awards, which need not be identical, (iv) to create sub-plans hereunder necessary to comply with laws and regulations of any foreign country in which the Company may seek to grant an Award to a person eligible under Section 1, and (v) to make all other determinations in the judgment of the Board of Directors necessary or desirable for the administration and interpretation of the Plan. The Board may correct any defect or supply any omission or reconcile any inconsistency in the Plan or in any Stock Option Agreement or Award in the manner and to the extent it shall deem expedient to carry the Plan, any Stock Option Agreement or Award into effect and it shall be the sole and final judge of such expediency. All decisions by the Board shall be final and binding on all interested persons. Neither the Company nor any member of the Board shall be liable for any action or determination relating to the Plan.

b. Appointment of Committee. To the extent permitted by applicable law, the Board may delegate any or all of its powers under the Plan to one or more committees or subcommittees of the Board (a “Committee”). If so delegated, all references in the Plan to the “Board” shall mean such Committee or the Board. The Compensation Committee of the Board of Directors is initially delegated all of the powers of the Board of Directors under the Plan, and shall continue to have such powers unless and until otherwise determined by the Board of Directors.

c. Delegation to Executive Officers. To the extent permitted by applicable law, the Board may delegate to one or more executive officers of the Company the power to grant Awards and exercise such other powers under the Plan as the Board may determine, provided that the Board shall fix the maximum number of Awards to be granted and the maximum number of shares issuable to any one Participant pursuant to Awards granted by such executive officers.

d. Applicability of Section Rule 16b-3. Notwithstanding anything to the contrary in the foregoing if, or at such time as, the Common Stock is or becomes registered under Section 12 of the Exchange Act of 1934, as amended (the “Exchange Act”), or any successor statute, the Plan shall be administered in a manner consistent with Rule 16b-3 promulgated thereunder, as it may be amended from time to time, or any successor rules (“Rule 16b-3”), such that all subsequent grants of Awards hereunder to Reporting Persons, as hereinafter defined, shall be exempt under such rule. Those provisions of the Plan which make express reference to Rule 16b-3 or which are required in order for certain option transactions to qualify for exemption under Rule 16b-3 shall apply only to such persons as are required to file reports under Section 16 (a) of the Exchange Act (a “Reporting Person”).

3. STOCK AVAILABLE FOR AWARDS.

a. Number of Shares. Subject to adjustment under Section 3(c), the (i) aggregate number of shares of Common Stock of the Company (the “Common Stock”) that may be issued pursuant to the Plan is 10,000,000 (the “Available Shares”). If an Award granted under the Plan is (i) canceled, expires, forfeited, is settled in cash, settled by delivery of fewer shares of Common Stock than the number of shares of Common Stock underlying the award or option or otherwise is terminated without delivery of the shares of Common Stock to the holder of such award or option or (ii) or shares that were withheld from such an Award or separately surrendered by the Participant in payment of an exercise price or taxes relating to such an Award shall be deemed to constitute shares not delivered and will be available under the Plan for subsequent awards.

b. Per-Participant Limit. Subject to adjustment under Section 3(c), no Participant may be granted Awards during any one fiscal year to receive, acquire or purchase more than 1,500,000 shares of Common Stock. No Participant may be granted an Annual Incentive Award (as defined below) in any fiscal year that exceeds four (4) times his or her base salary for that fiscal year.

c. Adjustment to Common Stock. Subject to Section 8, in the event of any stock split, reverse stock split, stock dividend, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, combination, exchange of shares, liquidation, spin-off, split-up, or other similar change in capitalization or similar event, (i) the number and class of Available Shares and the per-Participant share limit, (ii) the number and class of securities, vesting schedule and exercise price per share subject to each outstanding Option, (iii) the repurchase price per security subject to repurchase, and (iv) the terms of each other outstanding Award shall be adjusted by the Company (or substituted Awards may be made if applicable) to the extent the Board shall determine, in good faith, that such an adjustment (or substitution) is appropriate. Any such adjustment to outstanding Awards will be effected in a manner that precludes the enlargement of rights and benefits under such Awards.

4. STOCK OPTIONS.

a. General. The Board may grant options to purchase Common Stock (each, an “Option”) and determine the number of shares of Common Stock to be covered by each Option, the exercise price of each Option and the conditions and limitations applicable to the exercise of each Option and the shares of Common Stock issued upon the exercise of each Option, including, but not limited to, vesting provisions, repurchase provisions and restrictions relating to applicable federal or state securities laws. Each Option will be evidenced by a Stock Option Agreement, consisting of a Notice of Stock Option Award and a Stock Option Award Agreement or such other form of documentation as may be approved by the Board (collectively, a “Stock Option Agreement”).

b. Incentive Stock Options. An Option that the Board intends to be an incentive stock option (an “Incentive Stock Option”) as defined in Section 422 of the Code, as amended, or any successor statute (“Section 422”), shall be granted only to an employee of the Company and shall be subject to and shall be construed consistently with the requirements of Section 422 and regulations thereunder. The Board and the Company shall have no liability if an Option or any part thereof that is intended to be an Incentive Stock Option does not qualify as such. An Option or any part thereof that does not qualify as an Incentive Stock Option is referred to herein as a “Nonstatutory Stock Option” or “Nonqualified Stock Option.”

c. Dollar Limitation. For so long as the Code shall so provide, Options granted to any employee under the Plan (and any other incentive stock option plans of the Company) which are intended to qualify as Incentive Stock Options shall not qualify as Incentive Stock Options to the extent that such Options, in the aggregate, become exercisable for the first time in any one calendar year for shares of Common Stock with an aggregate Fair Market Value (as defined below) (determined as of the respective date or dates of grant) of more than $100,000. The amount of Incentive Stock Options which exceed such $100,000 limitation shall be deemed to be Nonqualified Stock Options. For the purpose of this limitation, unless otherwise required by the Code or regulations of the Internal Revenue Service or determined by the Board, Options shall be taken into account in

the order granted, and the Board may designate that portion of any Incentive Stock Option that shall be treated as Nonqualified Option in the event that the provisions of this paragraph apply to a portion of any Option. The designation described in the preceding sentence may be made at such time as the Committee considers appropriate, including after the issuance of the Option or at the time of its exercise.

d. Exercise Price. The Board shall establish the exercise price (or determine the method by which the exercise price shall be determined) at the time each Option is granted and specify the exercise price in the applicable Stock Option Agreement, provided, however, in no event may the per share exercise price of an Option be less than 100% of the Fair Market Value of the Common Stock on the date such Option is granted. In the case of an Incentive Stock Option granted to a Participant who, at the time of grant of such Option, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, then the exercise price shall be no less than 110% of the Fair Market Value of the Common Stock on the date of grant. Notwithstanding anything herein to the contrary, except as provided in Section 2(c), without the prior approval of the Company’s stockholders, neither the Company nor the Board will take any action to amend or modify any Award to lower the Award, exercise or conversion price applicable to such Award or otherwise cancel an outstanding Award for the purpose of repricing, replacing or regranting such Award previously granted for cash or other consideration.

e. Duration of Options. Each Option shall be exercisable at such times and subject to such terms and conditions as the Board may specify in the applicable Stock Option Agreement; provided, that the term of any Incentive Stock Option may not be more than ten (10) years from the date of grant. In the case of an Incentive Stock Option granted to a Participant who, at the time of grant of such Option, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Option shall be no longer than five (5) years from the date of grant.

f. Payment Upon Exercise. Common Stock purchased upon the exercise of an Option shall be paid for by one or any combination of the following forms of payment as permitted by the Board in its sole and absolute discretion:

i. by check payable to the order of the Company;

ii. only if the Common Stock is then publicly traded, by delivery of an irrevocable and unconditional undertaking by a creditworthy broker to deliver promptly to the Company sufficient funds to pay the exercise price, or delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a creditworthy broker to deliver promptly to the Company cash or a check sufficient to pay the exercise price;

iii. to the extent permitted in the applicable Stock Option Agreement, by delivery of shares of Common Stock owned by the Participant; or

iv. payment of such other lawful consideration as the Board may determine.

Except as otherwise expressly set forth in a Stock Option Agreement, the Board shall have no obligation to accept consideration other than cash. The fair market value of any shares of the Company’s Common Stock or other non-cash consideration which may be delivered upon exercise of an Option shall be determined in such manner as may be prescribed by the Board.

g. Determination of Fair Market Value. If, at the time an Option is granted under the Plan, the Company’s Common Stock is publicly traded under the Exchange Act, “Fair Market Value” shall mean (i) if the Common Stock is listed on any established stock exchange, its fair market value shall be the closing price for such stock on that date or the closing price as reported on NASDAQ; or (ii) if the Common Stock is traded in the over-the-counter securities market, then the average of the high bid and low bid quotations for the Common Stock as published in The Wall Street Journal. In the absence of an established market for the Common Stock,

the fair market value thereof shall be determined in good faith by the Board after taking into consideration all factors which it deems appropriate.

5. RESTRICTED STOCK.

a. Grants. The Board may (i) grant Awards to a Participant of restricted shares of Common Stock and shall determine the price, if any, to be paid by the Participant for each restricted share of Common Stock and (ii) shall provide the right of the Company to repurchase all or part of such shares at the issue price or other stated or formula price from the Participant in the event that the conditions specified by the Board in the applicable Award are not satisfied prior to the end of the applicable restriction period or periods established by the Board for such Award (each, a “Restricted Stock Award”).

b. Terms and Conditions. The Board shall determine the terms and conditions of any such Restricted Stock Award. Any stock certificates issued in respect of a Restricted Stock Award shall be registered in the name of the Participant and, unless otherwise determined by the Board, deposited by the Participant, together with a stock power endorsed in blank, with the Company (or its designee). After the expiration of the applicable restriction periods, the Company (or such designee) shall deliver the certificates no longer subject to such restrictions to the Participant or, if the Participant has died, to the beneficiary designated by a Participant, in a manner determined by the Board, to receive amounts due or exercise rights of the Participant in the event of the Participant’s death (the “Designated Beneficiary”). In the absence of an effective designation by a Participant, Designated Beneficiary shall mean the Participant’s estate.

6. OTHER STOCK-BASED AWARDS.

The Board shall have the right to grant other Awards based upon the Common Stock having such terms and conditions as the Board may determine, including, without limitation, the grant of shares based upon certain conditions, the grant of securities convertible into Common Stock and the grant of stock appreciation rights, phantom stock awards, performance stock, deferred stock, restricted stock units, shares of Common Stock not subject to any restrictions or stock units.

7. PERFORMANCE AND ANNUAL INCENTIVE AWARDS.

a. Performance Conditions. The right of a Participant to exercise or receive a grant or settlement of any Award, and the timing thereof, may be subject to such performance conditions as may be specified by the Board. The Board may use such business criteria and other measures of performance as it may deem appropriate in establishing any performance conditions, and may exercise its discretion to reduce the amounts payable under any Performance and Annual Incentive Award subject to performance conditions. If and to the extent required under Section 162(m) of the Code, any power or authority relating to a Performance Award intended to qualify under Section 162(m) of the Code, shall be exercised by the Committee and not the Board. “Annual Incentive Awards” shall mean a cash Award subject to the attainment of performance goals over a performance period. “Performance Award” means a stock-based Award subject to the attainment of performance goals over a performance period.

b. Performance Awards Granted to Designated Covered Employees. If and to the extent that the Committee determines that a Performance Award or Annual Incentive Award to be granted to a Participant who is designated by the Committee as likely to be a Covered Employee should qualify as “performance-based compensation” for purposes of Section 162(m) of the Code, the grant, exercise and/or settlement of such Performance Award or Annual Incentive Award shall be contingent upon achievement of pre-established performance goals and other terms set forth in Section 7. Nothing in this Section 7 shall preclude the Board from granting an Award or Annual Incentive Award under this Plan to a person, who is likely to be a Covered Employee or otherwise, that is not intended to qualify as “performance-based compensation” for purposes of

Section 162(m) of the Code upon such terms and conditions as may be determined by the Board, without regard to the limitations set forth in this Section 7.

c. Performance Goals Generally. The performance goals for such Performance Awards or Annual Incentive Award shall consist of one or more business criteria and a targeted level or levels of performance with respect to each of such criteria, as specified by the Committee consistent with this Section 7. Performance goals shall be objective and shall otherwise meet the requirements of Section 162(m) of the Code and regulations thereunder including the requirement that the level or levels of performance targeted by the Committee result in the achievement of performance goals being “substantially uncertain.” The Committee may determine that such Performance Awards or Annual Incentive Award shall be granted, exercised and/or settled upon achievement of any one performance goal or that two or more of the performance goals must be achieved as a condition to grant, exercise and/or settlement of such Performance Awards. Performance goals may differ for Performance Awards or Annual Incentive Award granted to any one Participant or to different Participants.

d. Business Criteria. The Committee may establish Performance Goals that are measured either individually, alternatively or in any combination, applied to either the Company as a whole or to a specified subsidiary or business unit, and measured over a performance period, on an absolute basis or relative to a pre-established target to a previous year’s result or to a designated comparison group, in each case as specified by the Committee in the Award. The business criteria that may be used exclusively by the Committee in establishing Performance Goals for such an Award shall be the following: economic value added; earnings before interest, taxes, depreciation and amortization; earnings before interest and taxes; cash flow; earnings per share; operating income; operating income before income taxes; net income; net income before income taxes; operating margin; ratio of debt to stockholder’s equity; reduction of debt, return on equity; return on assets; revenue; and total shareholder return; or any other individual Company business-related objective that is objectively determinable within the meaning of Section 162(m) and Treasury Regulations promulgated thereunder including, but, not limited to, market penetration, total market capitalization and enterprise value, business retention, new product generation, cost controls and targets (including costs of capital), customer satisfaction, employee satisfaction, agency ratings, management of employment practices and employee benefits, supervision of litigation and information technology, implementation of business process controls and recruiting and retaining personnel. In addition, geographical expansion and clinical and product developments or regulatory milestones may be utilized as Performance Targets. The business criteria relating to financial performance may be subject to adjustment, as determined by the Committee, including, without limitation, to remove the effect of (i) charges for restructurings, asset impairments or discontinued operations, (ii) the payment of bonuses; (iii) non-cash charges such as the amortization of intangible assets or equity compensation, (iv) items of gain, loss or expense, determined to be extraordinary or unusual in nature or infrequent in occurrence, (v) items of gain, loss or expense related to the disposal or acquisition of a product-line, segment or business, or (vi) items of gain, loss or expense related to any change in accounting principles during the applicable performance period since September 27, 2008. A “performance period” shall be a calendar year, fiscal year of the Company or other longer or shorter period designated by the Compensation Committee.

e. Timing For Establishing Performance Goals. Performance goals shall be established no later after 25% of a performance period has elapsed after the beginning of any performance period applicable to such Performance Awards or Annual Incentive Awards, or at such other date as may be required or permitted for “performance-based compensation” under Section 162(m) of the Code.

f. Settlement of Performance Awards; Other Terms. Settlement of such Performance Awards or Annual Incentive Awards shall be in cash, Stock, other Awards or other property, in the discretion of the Committee. The Committee may, in its discretion, reduce the amount of a settlement otherwise to be made in connection with such Performance Awards or Annual Incentive Awards. The Committee shall specify the circumstances in which such Performance Awards or Annual Incentive Awards shall be paid or forfeited in the event of termination of Service by the Participant prior to the end of a performance period or settlement of Performance Awards or Annual Incentive Awards.

g. Written Determinations. All determinations by the Committee as to the establishment of performance goals and the achievement of performance goals relating to Performance Awards or Annual Incentive Awards, shall be made in writing in the case of any Award intended to qualify under Section 162(m) of the Code. To the extent required to comply with Section 162(m) of the Code, the Committee may delegate any responsibility relating to such Performance Awards or Annual Incentive Awards.

h. Status of Performance Awards Under Code Section 162(m). It is the intent of the Company that Performance Awards or Annual Incentive Awards under this Section 7 hereof granted to persons who are designated by the Committee as likely to be Covered Employees within the meaning of Section 162(m) of the Code and regulations thereunder shall, if so designated by the Committee, constitute “qualified performance-based compensation” within the meaning of Section 162(m) of the Code and regulations thereunder. Accordingly, the terms of this Section 7, including the definitions of Covered Employee and other terms used therein, shall be interpreted in a manner consistent with Section 162(m) of the Code and regulations thereunder. The foregoing notwithstanding, because the Committee cannot determine with certainty whether a given Participant will be a Covered Employee with respect to a fiscal year that has not yet been completed, the term Covered Employee as used herein shall mean only a person designated by the Committee, at the time of grant of Performance Awards or Annual Incentive Awards, as likely to be a Covered Employee with respect to that fiscal year. If any provision of the Plan or any agreement relating to such Performance Awards or Annual Incentive Awards does not comply or is inconsistent with the requirements of Section 162(m) of the Code or regulations thereunder, such provision shall be construed or deemed amended to the extent necessary to conform to such requirements.

8. GENERAL PROVISIONS APPLICABLE TO AWARDS.

a. Transferability of Awards. Except as the Board may otherwise determine or provide in an Award, Awards shall not be sold, assigned, transferred, pledged or otherwise encumbered by the person to whom they are granted, either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, during the life of the Participant, shall be exercisable only by the Participant; provided, however, except as the Board may otherwise determine or provide in an Award, other than an Incentive Stock Option, may be transferred pursuant to a qualified domestic relations order (as defined in Employee Retirement Income Security Act of 1974, as amended) or to a grantor-retained annuity trust or a similar estate-planning vehicle in which the trust is bound by all provisions of the Stock Option Agreement and Restricted Stock Award, which are applicable to the Participant. References to a Participant, to the extent relevant in the context, shall include references to authorized transferees.

b. Documentation. Each Award under the Plan shall be evidenced by a written instrument in such form as the Board shall determine or as executed by an officer of the Company pursuant to authority delegated by the Board. Each Award may contain terms and conditions in addition to those set forth in the Plan, provided that such terms and conditions do not contravene the provisions of the Plan or applicable law. Notice of a grant shall be given to each Participant to whom an Award is so granted within a reasonable time after the determination has been made.

c. Board Discretion. The terms of each type of Award need not be identical, and the Board need not treat Participants uniformly.

d. Additional Award Provisions. The Board may, in its sole discretion, include additional provisions in any Stock Option Agreement, Restricted Stock Award or other Award granted under the Plan, including without limitation restrictions on transfer, repurchase rights, commitments to pay cash bonuses, to make, arrange for or guaranty loans or to transfer other property to Participants upon exercise of Awards, or transfer other property to Participants upon exercise of Awards, or such other provisions as shall be determined by the Board; provided that such additional provisions shall not be inconsistent with any other term or condition of the Plan or applicable law.

e. Termination of Status. The Board shall determine the effect on an Award of the disability (as defined in Code Section 22(e)(3)), death, retirement, authorized leave of absence or other change in the employment or other status of a Participant and the extent to which, and the period during which, the Participant, or the Participant’s legal representative, conservator, guardian or Designated Beneficiary, may exercise rights under the Award, subject to applicable law and the provisions of the Code related to Incentive Stock Options.

f. Change of Control of the Company.

i. Unless otherwise expressly provided in the applicable Stock Option Agreement or Restricted Stock Award or other Award, in connection with the occurrence of a Change in Control (as defined below), the Board shall, in its sole discretion as to any outstanding Award (including any portion thereof; on the same basis or on different bases, as the Board shall specify), take one or any combination of the following actions:

A. make appropriate provision for the continuation of such Award by the Company or the assumption of such Award by the surviving or acquiring entity and by substituting on an equitable basis for the shares then subject to such Award either (x) the consideration payable with respect to the outstanding shares of Common Stock in connection with the Change of Control, (y) shares of stock of the surviving or acquiring corporation, or (z) such other securities as the Board deems appropriate, the Fair Market Value of which shall not materially differ from the Fair Market Value of the shares of Common Stock subject to such Award immediately preceding the Change of Control (as determined by the Board in its sole discretion;

B. accelerate the date of exercise or vesting of such Award;

C. permit the exchange of such Award for the right to participate in any stock option or other employee benefit plan of any successor corporation;

D. provide for the repurchase of the Award for an amount equal to the difference of (i) the consideration received per share for the securities underlying the Award in the Change of Control minus (ii) the per share exercise price of such securities. Such amount shall be payable in cash or the property payable in respect of such securities in connection with the Change of Control. The value of any such property shall be determined by the Board in its discretion; or

E. Solely with respect to transactions described in Section 8(f)(i)(F)(c) below, provide for the termination of such Award immediately prior to the consummation of the Change of Control; provided that no such termination will be effective if the Change of Control is not consummated.

F. For the purpose of this Agreement, a “Change of Control” shall mean:

(a) The acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or more of the then outstanding shares of voting stock of the Company (the “Voting Stock”); provided, however, that any acquisition by the Company or its subsidiaries, or any employee benefit plan (or related trust) of the Company or its subsidiaries of 20% or more of Voting Stock shall not constitute a Change in Control; and provided, further, that any acquisition by a corporation with respect to which, following such acquisition, more than 50% of the then outstanding shares of common stock of such corporation, is then beneficially owned, directly or indirectly, by all or substantially all of the individuals and entities who were the beneficial owners of the Voting Stock immediately prior to such acquisition in substantially the same proportion as their ownership, immediately prior to such acquisition, of the Voting Stock, shall not constitute a Change in Control; or

(b) Any transaction which results in the Continuing Directors (as defined in the Certificate of Incorporation of the Company) constituting less than a majority of the Board of Directors of the Company; or

(c) The consummation of (i) a reorganization, merger or consolidation (any of the foregoing, a “Merger”), in each case, with respect to which the individuals and entities who were the beneficial owners of the Voting Stock immediately prior to such Merger do not, following such Merger, beneficially own, directly or indirectly, more than 50% of the then outstanding shares of common stock of the corporation resulting from the Merger (the Resulting Corporation”) as a result of the individuals’ and entities’ shareholdings in the Company immediately prior to the consummation of the Merger and without regard to any of the individual’s and entities’ shareholdings in the Resulting Corporation immediately prior to the consummation of the Merger, (ii) a complete liquidation or dissolution of the Company, or (iii) the sale or other disposition of all or substantially all of the assets of the Company, excluding a sale or other disposition of assets to a subsidiary of the Company.

g. Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company or termination of an Award under Section 8(f)(i)(E), the Board shall notify each Participant as soon as practicable prior to the effective date of such proposed transaction. The Board in its sole discretion may provide for a Participant to have the right to exercise his or her Award until fifteen (15) days prior to such transaction as to all of the shares of Common Stock covered by the Option or Award, including shares as to which the Option or Award would not otherwise be exercisable, which exercise may in the sole discretion of the Board, be made subject to and conditioned upon the consummation of such proposed transaction. In addition, the Board may provide that any Company repurchase option applicable to any shares of Common Stock purchased upon exercise of an Option or Award shall lapse as to all such shares of Common Stock, provided the proposed dissolution and liquidation takes place at the time and in the manner contemplated. To the extent it has not been previously exercised, an Award will terminate upon the consummation of such proposed action.

h. Assumption of Options Upon Certain Events. In connection with a merger or consolidation of an entity with the Company or the acquisition by the Company of property or stock of an entity, the Board may grant Awards under the Plan in substitution for stock and stock-based awards issued by such entity or an affiliate thereof. The substitute Awards shall be granted on such terms and conditions as the Board considers appropriate in the circumstances.

i. Parachute Payments and Parachute Awards. Notwithstanding the provisions of Section 8(f), if, in connection with a Change of Control described therein, a tax under Section 4999 of the Code would be imposed on the Participant (after taking into account the exceptions set forth in Sections 280G(b)(4) and 280G(b)(5) of the Code) and not otherwise paid for by the Company, then the number of Awards which shall become exercisable, realizable or vested as provided in such Section shall be reduced (or delayed), to the minimum extent necessary, so that no such tax would be imposed on the Participant (the Awards not becoming so accelerated, realizable or vested, the “Parachute Awards”); provided, however, that if the “aggregate present value” of the Parachute Awards would exceed the tax that, but for this sentence, would be imposed on the Participant under Section 4999 of the Code in connection with the Change of Control, then the Awards shall become immediately exercisable, realizable and vested without regard to the provisions of this sentence. For purposes of the preceding sentence, the “aggregate present value” of an Award shall be calculated on an after-tax basis (other than taxes imposed by Section 4999 of the Code) and shall be based on economic principles rather than the principles set forth under Section 280G of the Code and the regulations promulgated thereunder. All determinations required to be made under this Section 7(i) shall be made by the Company.

j. Amendment of Awards. The Board may amend, modify or terminate any outstanding Award including, but not limited to, substituting therefor another Award of the same or a different type, changing the date of exercise or realization, and converting an Incentive Stock Option to a Nonstatutory Stock Option, provided that the Participant's consent to such action shall be required unless the Board determines that the action, taking into account any related action, would not materially and adversely affect the Participant.

k. Conditions on Delivery of Stock. The Company will not be obligated to deliver any shares of Common Stock pursuant to the Plan or to remove restrictions from shares previously delivered under the Plan until (i) all conditions of the Award have been met or removed to the satisfaction of the Company, (ii) in the opinion of the Company’s counsel, all other legal matters in connection with the issuance and delivery of such shares have been satisfied, including any applicable securities laws and any applicable stock exchange or stock market rules and regulations, and (iii) the Participant has executed and delivered to the Company such representations or agreements as the Company may consider appropriate to satisfy the requirements of any applicable laws, rules, or regulations.

l. Acceleration. The Board may at any time provide that any Award shall become immediately exercisable in full or in part, or that any other stock-based Awards may become exercisable in full or in part or free of some or all restrictions or conditions, or otherwise realizable in full or in part, as the case may be, despite the fact that the foregoing actions may (i) cause the application of Sections 280G and 4999 of the Code if a Change In Control of the Company occurs, or (ii) disqualify all or part of the Option as an Incentive Stock Option. In addition, the Board may, in its sole discretion, and in all instances subject to any relevant tax and accounting considerations which may adversely impact or impair the Company, extend the dates during which all or any particular Options or Awards granted under the Plan may be exercised.

m. Participation in Foreign Countries. The Board shall have the authority to adopt such modifications, procedures, and subplans as may be necessary or desirable to comply with provisions of the laws of foreign countries in which the Company or its Subsidiaries may operate to assure the viability of the benefits from Awards granted to Participants performing services in such countries and to meet the objectives of the Plan.

9. WITHHOLDING.

The Company shall have the right to deduct from payments of any kind otherwise due to the optionee or recipient of an Award any federal, state, or local taxes of any kind required by law to be withheld with respect to any shares issued upon exercise of Options under the Plan or the purchase of shares subject to the Award. Subject to the prior approval of the Company, which may be withheld by the Company in its sole discretion, the optionee or recipient of an Award may elect to satisfy such obligation, in whole or in part, (a) by causing the Company to withhold shares of Common Stock otherwise issuable pursuant to the exercise of an Option or the purchase of shares subject to an Award or (b) by delivering to the Company shares of Common Stock already owned by the optionee or Award recipient of an Award. The shares so delivered or withheld shall have a fair market value of the shares used to satisfy such withholding obligation as shall be determined by the Company as of the date that the amount of tax to be withheld is to be determined. An optionee or recipient of an Award who has made an election pursuant to this Section may only satisfy his or her withholding obligation with shares of Common Stock which are not subject to any repurchase, forfeiture, unfulfilled vesting, or other similar requirements.

10. NO EXERCISE OF OPTION IF ENGAGEMENT OR EMPLOYMENT TERMINATED FOR CAUSE.

If the employment or engagement of any Participant is terminated “for Cause”, the Award may terminate, upon a determination of the Board, on the date of such termination and the Option shall thereupon not be exercisable to any extent whatsoever and the Company shall have the right to repurchase any shares of Common Stock subject to a Restricted Stock Award whether or not such shares have vested. For purposes of this Section 10, “for Cause” shall be defined as follows: (i) if the Participant has executed an employment agreement, the definition of “cause” contained therein, if any, shall govern, or (ii) if the Participant has not executed an employment agreement in which the definition of “cause” is provided, conduct, as determined by the Board of Directors, involving one or more of the following: (a) gross misconduct or inadequate performance by the Participant which is injurious to the Company; or (b) the commission of an act of embezzlement, fraud or theft, which results in economic loss, damage or injury to the Company; or (c) the unauthorized disclosure of any trade secret or confidential information of the Company (or any client, customer, supplier, or other third party who has a business relationship with the Company) or the violation of any noncompetition or nonsolicitation

covenant or assignment of inventions obligation with the Company; or (d) the commission of an act which constitutes unfair competition with the Company or which induces any customer or prospective customer of the Company to breach a contract with the Company or to decline to do business with the Company (to the extent such restriction is enforceable under applicable state law; or (e) the indictment or conviction of the Participant for a felony or serious misdemeanor offense, either in connection with the performance of his or her obligations to the Company or which shall adversely affect the Participant’s ability to perform such obligations; or (f) the commission of an act of fraud or breach of fiduciary duty which results in loss, damage or injury to the Company; or (g) the failure of the Participant to perform in a material respect his or her employment, consulting or advisory obligations without proper cause. The Board may in its discretion waive or modify the provisions of this Section at a meeting of the Board with respect to any individual Participant with regard to the facts and circumstances of any particular situation involving a determination under this Section.

11. MISCELLANEOUS.

a. Definitions.

i. “Company”, for purposes of eligibility under the Plan, shall include any present or future subsidiary corporations of Hologic, Inc., as defined in Section 424(f) of the Code (a “Subsidiary”), and any present or future parent corporation of Hologic, Inc., as defined in Section 424(e) of the Code. For purposes of Awards other than Incentive Stock Options, the term “Company” shall include any other business venture in which the Company has a direct or indirect significant interest, as determined by the Board in its sole discretion.

ii. “Code” means the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder.

iii. “Effective Date” means the date the Plan is approved by the Company’s stockholders.

iv. “Employee” for purposes of eligibility under the Plan shall include a person to whom an offer of employment has been extended by the Company.

b. No Right To Employment or Other Status. No person shall have any claim or right to be granted an Award, and the grant of an Award shall not be construed as giving a Participant the right to continued employment or any other relationship with the Company. The Company expressly reserves the right at any time to dismiss or otherwise terminate its relationship with a Participant free from any liability or claim under the Plan. Except as specifically provided by the Board in any particular case, the loss of existing or potential profit and Awards granted under this Plan will not constitute an element of damages in the event of termination of an employment relationship even if the termination is in violation of an obligation of the Company to the Participant.

c. Compliance with Law. The Company shall not be required to sell or issue any shares of Common Stock under any Award if the sale or issuance of such shares would constitute a violation by the Participant, any other individual exercising an Option, or the Company of any provision of any law or regulation of any governmental authority, including without limitation any federal or state securities laws or regulation. If at any time the Company shall determine, in its discretion, that the listing, registration or qualification of any share subject to an Award up on any security exchange or under any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the issuance or purchase of shares hereunder, no shares of Common Stock may be issued or sold to the Participant or any other individual exercising an Option pursuant to such Award unless such listing, registration, qualification, consent, or approval shall have been effected or obtained free of any conditions not acceptable to the Company, and any delay caused thereby shall in no way effect the date of termination of the Award. Any determination in this connection by the Board shall be final, binding and conclusive. The Company may, but shall in no event be obligated to, register any securities covered hereby pursuant to the Securities Act. The Company shall not be obligated to take any affirmative action in order to cause the exercise of an Option or the issuance of shares of Common Stock pursuant to the Plan to comply with any law or regulation of any governmental authority. As to any jurisdiction that expressly imposes that a Option

shall not be exercised until the shares of Common Stock covered by such Option are registered or exempt from registration, the exercise of such Option (under circumstances in which the laws of such jurisdiction apply) shall be deemed conditioned up on the effectiveness of such registration or availability of such an exemption.

d. No Rights As Stockholder. Subject to the provisions of the applicable Award, no Participant or Designated Beneficiary shall have any rights as a stockholder with respect to any shares of Common Stock to be distributed with respect to an Award until becoming the record holder thereof.

e. Effective Date and Term of Plan. The Plan shall become effective on the date on which it is approved by the stockholders. No Awards shall be granted under the Plan after the completion of ten years from the date on which the Plan was approved by the stockholders, but Awards previously granted may extend beyond that date.

f. Amendment of Plan. The Board of Directors may, at any time, suspend or terminate the Plan or revise or amend it in any respect whatsoever. An Amendment shall be contingent on approval of the Company’s stockholders to the extent stated by the Board, required by applicable law or required by applicable stock exchange listing requirements.

g. Governing Law. The provisions of the Plan and all Awards made hereunder shall be governed by and interpreted in accordance with the laws of the State of Delaware, without regard to any applicable conflicts of law principles.
