SERIES D PREFERRED STOCK AND WARRANT PURCHASE AGREEMENT

This SERIES D PREFERRED STOCK AND WARRANT PURCHASE AGREEMENT (this “Agreement”) is made and entered into this 12th day of April, 2006 by and among Nanosphere, Inc., a Delaware corporation (the “Company”), Xxxx Capital Venture Fund 2005, L.P., a Delaware limited partnership and Brookside Capital Partners Fund, L.P., a Delaware limited partnership (collectively, “Xxxx Capital”), certain entities related to Xxxx Capital as listed on Schedule I and the other entities and individuals as listed on Schedule I attached hereto (each such purchaser is referred to herein as a “Purchaser,” and such purchasers collectively are referred to herein as the “Purchasers”). Certain terms used and not otherwise defined in the text of this Agreement are defined in Section 9 hereof.

WITNESSETH

WHEREAS, the Company desires to issue and to sell to the Purchasers, and the Purchasers desire to purchase from the Company, the shares of Series D Preferred Stock (as hereinafter defined), all in accordance with the terms and provisions of this Agreement;

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants herein contained, the parties hereto hereby agree as follows:

1. Authorization of Securities.

1.1 The Company has authorized the issuance and sale of up to 162,857,142 shares of its Series D Preferred Stock, par value $0.01 per share (“Series D Preferred Stock”), which will be convertible into shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), and which will have the rights, preferences and privileges set forth in the form of Amended and Restated Certificate of Incorporation attached hereto as Exhibit A (the “Amended and Restated Certificate of Incorporation”). The shares of Common Stock into which the Series D Preferred Stock is convertible are sometimes referred to herein as the “Conversion Shares” and the shares of Series D Preferred Stock, the Conversion Shares and the Warrants and the Warrant Shares (each as defined below) are sometimes referred to herein collectively as the “Securities”.

1.2 The Company has authorized the issuance to each Purchaser of a Warrant dated as of the date hereof substantially in the form attached hereto as Exhibit C to purchase the number of shares of the Company’s Series D Preferred Stock set forth opposite such Purchaser’s name on Schedule I hereto. The Warrants issued pursuant to this Agreement are collectively referred to herein as the “Warrants”. The shares of Series D Preferred Stock for which the Warrants are exercisable are referred to herein collectively as the “Warrant Shares”.

2. Sale and Purchase of the Securities. Subject to the terms and conditions contained in this Agreement, each Purchaser agrees to purchase, severally and not jointly with respect to the other Purchasers, and the Company agrees to sell and issue to each Purchaser, at the Closing (as defined below), that number of shares of Series D Preferred Stock set forth opposite such Purchaser’s name on Schedule I attached hereto at a purchase price of $0.35 per share of Series D Preferred Stock (the “Purchase Price”) and the Warrants to purchase the Warrant Shares set forth opposite such Purchaser’s name on Schedule I attached hereto.

3. Closing; Payment of Purchase Price; Use of Proceeds.

3.1 Closing. The closing (the “Closing”) with respect to the transaction contemplated in Section 2 hereof shall take place remotely via the exchange of documents and signatures at 10:00 a.m. on April 12, 2006, or at such other time and place as the Company and Purchasers mutually agree upon, orally or in writing (the “Closing Date”). At the Closing, the Company shall deliver to each Purchaser (i) a certificate representing the shares of Series D Preferred Stock being purchased by such Purchaser (registered in the name of such Purchaser) and (ii) a Warrant to purchase the initial number of Warrant Shares set forth opposite such Purchaser’s name on Schedule I (registered in the name of such Purchaser), against payment of the purchase price therefor by (A) wire transfer (of immediately available funds) to a bank account designated by the Company; (B) by cancellation of indebtedness of the Company to the Purchaser, including interest; (C) cancellation of outstanding warrants and rights associated therewith; or (D) by any combination of such methods, in each case as set forth on Schedule I hereto.

3.2 Use of Proceeds. The Company shall use the proceeds from the sale of Series D Preferred Stock hereunder for general corporate purposes.

4. Representations and Warranties of the Purchasers; Restrictions on Transfer. Each Purchaser, severally as to itself and not jointly, represents and warrants to the Company as follows:

4.1 Organization. Any Purchaser which is a corporation, limited liability company, partnership, trust or other entity represents that such Purchaser is validly existing or formed and in good standing under the laws of its jurisdiction of organization or formation, and has all corporate, limited liability company, partnership, trust or other entity power (as the case may be) and authority to enter into this Agreement and the other Transaction Documents and instruments referred to herein to which it is a party and to consummate the transactions contemplated hereby and thereby.

4.2 Validity. The execution, delivery and performance of this Agreement, and the other Transaction Documents and instruments referred to herein, in each case to which such Purchaser is a party, and the consummation by such Purchaser of the transactions contemplated hereby and thereby, have been duly authorized by all necessary action on the part of such Purchaser. This Agreement has been duly executed and delivered by such Purchaser, and the other Transaction Documents and instruments referred to herein to which it is a party will be duly executed and delivered by such Purchaser, and each such agreement constitutes or will constitute a valid and binding obligation of such Purchaser enforceable against it in accordance with its terms.

4.3 Brokers. There is no broker, investment banker, financial advisor, finder or other person which has been retained by or is authorized to act on behalf of such Purchaser who might be entitled to any fee or commission for which the Company will be liable in connection with the execution of the Transaction Documents and the consummation of the transactions contemplated thereby.

4.4 Investment Representations and Warranties. Such Purchaser understands that the issuance of the Securities to the Purchasers has not been, and will not be, registered under the Securities Act.

4.5 Acquisition for Own Account. This Agreement is made with the Purchaser in reliance upon the Purchaser’s representations to the Company contained in this Agreement, including, without limitation, that the Securities to be acquired by the Purchaser will be acquired for investment for the Purchaser’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Purchaser has no present intention of selling, granting any participation in, or otherwise distributing the same; it being understood, the foregoing notwithstanding, that certain of the Securities being purchased by Xxxxx & Company LLC are being purchased as nominee for up to eleven (11) total employees or Affiliates of Xxxxx & Company LLC, each of whom is an “accredited investor” as such terms is defined in Rule 501(a) of Regulation D promulgated under the Securities Act. The Purchaser further represents that the Purchaser does not presently have any contract, undertaking, agreement or arrangement with any Person to sell, transfer or grant participations to such Person or to any third Person, with respect to any of the Securities. Any Purchaser which is a corporation, limited liability company, partnership, trust or other entity has not been formed for the specific purpose of acquiring the Securities.

4.6 Disclosure of Information. The Purchaser has had an opportunity to discuss the Company’s business, management, financial affairs and the terms and conditions of the offering of the Securities with the Company’s management. The foregoing, however, does not limit or modify the representations and warranties of the Company in Section 5 of this Agreement or the right of the Purchasers to rely thereon.

4.7 Ability to Protect Its Own Interests and Bear Economic Risks. By reason of the business and financial experience of Purchaser (or, if the Purchaser is an entity, of its managers), the Purchaser has the capacity to protect his, her or its own interests in connection with the transactions contemplated by this Agreement and the other Transaction Documents. Such Purchaser is able to bear the economic risk of an investment in the Securities and is able to sustain a loss of all of its investment in the Securities without economic hardship if such a loss should occur.

4.8 Accredited Investor. The Purchaser is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D promulgated under the Securities Act.

4.9 Restricted Securities.

(a) The Purchaser understands that the Securities have not been registered under the Securities Act, by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of the Purchaser’s representations as expressed in this Agreement. The Purchaser understands that the

Securities are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, the Purchaser must hold the Securities indefinitely unless they are registered with the Securities and Exchange Commission and qualified by state authorities, or an exemption from such registration and qualification requirements is available. The Purchaser acknowledges that the Company has no obligation to register or qualify the Securities, or the shares of Common Stock into which they may be converted or exchanged for resale, except as expressly set forth in the Transaction Documents. The Purchaser further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Securities, and on requirements relating to the Company which are outside of the Purchaser’s control, and which the Company is under no obligation and may not be able to satisfy.

(b) Such Purchaser is aware of the provisions of Rule 144 under the Securities Act which permit limited resale of securities purchased in a private placement.

4.10 No Public Market. Such Purchaser understands that no public market now exists for any of the Securities issued by the Company, and that the Company has made no assurances that a public market will ever exist for the Securities.

4.11 Residence. If the Purchaser is an individual, then the Purchaser resides in the state or province identified as the address of the Purchaser set forth on Schedule I hereto; if the Purchaser is a corporation, limited liability company, partnership, trust or other entity, then the principal office of the Purchaser is identified as the address of the Purchaser set forth on Schedule I hereto.

5. Representations and Warranties by the Company. The Company represents and warrants to each Purchaser that, except as set forth on the Disclosure Schedule attached to this Agreement (the “Disclosure Schedule”), which exceptions shall be deemed to be part of the representations and warranties made hereunder, the following representations are true and complete as of the Closing, except as otherwise indicated in this Section 5:

Additionally, assuming the accuracy of the representations of the Purchasers in Section 4 of this Agreement, and subject to the filings described in Section 5.5(iii) of this Agreement, the Securities will be issued in compliance with all applicable federal and state securities laws.

5.8 No Conflicts. The execution, delivery and performance of each of the Transaction Documents by the Company, the execution and filing of the Amended and Restated Certificate of Incorporation by the Company, and the consummation of the transactions contemplated hereby and thereby (including, without limitation, the issuance and reservation for issuance, as applicable, of the Series D Preferred Stock and the Conversion Shares) will not (i) result in a violation of the Charter Documents, (ii) conflict with or result in the breach of the terms, conditions or provisions of or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give rise to any right of termination,

acceleration or cancellation under, any agreement, lease, mortgage, license, indenture, instrument or other contract to which the Company is a party, (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including, without limitation, U.S. federal and state securities laws and regulations) applicable to the Company or by which any property or asset of the Company is bound or affected, or (iv) result in the creation of any Encumbrance upon any of their assets. The Company is not in violation of its Charter Documents, and the Company is not in default (and no event has occurred which, with notice or lapse of time or both, would cause the Company to be in default) under, nor has there occurred any event giving others (with notice or lapse of time or both) any rights of termination, amendment, acceleration or cancellation of, any material agreement, indenture or instrument to which the Company is a party. The business of the Company is not being conducted in violation in any material respect of any law, ordinance or regulation of any Governmental Entity.

5.9 Material Contracts. Each Material Contract of the Company is listed on Schedule 5.9 hereof. Each such contract is the legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except to the extent that enforceability may be limited by bankruptcy, insolvency, fraudulent conveyance or other similar laws affecting creditors’ rights generally and by general equitable principles. Except as set forth on Schedule 5.9 hereof, there has not occurred any material breach, violation or default or any event that, with the lapse of time, the giving of notice or the election of any Person, or any combination thereof, would constitute a material breach, violation or default by the Company under any such contract or, to the knowledge of the Company, by any other Person to any such contract. The Company has not been notified that any party to any Material Contract intends to cancel, terminate, not renew or exercise an option under any Material Contract, whether in connection with the transactions contemplated hereby or otherwise.

5.10 Right of First Refusal; Stockholders Agreement. Except as set forth on Schedule 5.10, and except with respect to any rights granted to the Purchasers pursuant to the terms of the Amended and Restated Certificate of Incorporation, this Agreement or the other Transaction Documents or the transactions contemplated hereby or thereby, no party has any right of first refusal, right of first offer, right of co-sale, preemptive right or other similar right regarding the Company’s securities. There are no provisions of the Charter Documents, no agreements to which the Company is a party and no agreements by which the Company is bound other than the Amended and Restated Certificate of Incorporation, this Agreement or the other Transaction Documents, which (i) may affect or restrict the voting rights of the Purchasers with respect to the Securities in their capacity as stockholders of the Company, (ii) restrict the ability of the Purchasers, or any successor thereto or assignee or transferee thereof, to transfer the Securities, (iii) would adversely affect the Company’s or any Purchaser’s right or ability to consummate the transactions contemplated by this Agreement or comply with the terms of the other Transaction Documents or the Amended and Restated Certificate of Incorporation and the transactions contemplated hereby or thereby, (iv) require the vote of more than a majority of the Company’s issued and outstanding capital stock, voting together as a single class, to take or prevent any corporate action, other than those matters requiring a class vote under Delaware law, or (v) entitle any party to nominate or elect any director of the Company or require any of the Company’s stockholders to vote for any such nominee or other person as a director of the Company in each case.

5.11 Previous Issuances Exempt. All shares of capital stock and other securities issued by the Company prior to the Closing Date have been issued in transactions exempt from the registration requirements under the Securities Act and all applicable state securities or “blue sky” laws, and in compliance with all applicable corporate laws. The Company has not violated the Securities Act or any applicable state securities or “blue sky” laws in connection with the issuance of any shares of capital stock or other securities prior to the Closing Date. The Company has not offered any of its capital stock, or any other securities, for sale to, or solicited any offers to buy any of the foregoing from the Company, or otherwise approached or negotiated with any other Person in respect thereof, in such a manner as to require registration under the Securities Act.

5.12 No Integrated Offering. Neither the Company, nor any of its Affiliates or any other Person acting on the Company’s behalf, has directly or indirectly engaged in any form of general solicitation or general advertising with respect to the Securities nor have any of such Persons made any offers or sales of any security of the Company or its Affiliates or solicited any offers to buy any security of the Company or its Affiliates under circumstances that would require registration of the Securities under the Securities Act or cause this offering of Securities to be integrated with any prior offering of securities of the Company for purposes of the Securities Act.

(a) The Company has provided to the Purchasers true and correct copies of its unaudited consolidated balance sheet dated as of December 31, 2005 (the “Balance Sheet Date”), the audited balance sheets as of 2004 (in draft form) and 2003, and the related statements of operation, changes in stockholder’s equity and cash flows for the twelve months ended December 31, 2005, December 31, 2004 and December 31, 2003 (the “Financial Statements”). The Financial Statements present fairly, in all material respects, the financial position and operating results of the Company as of the respective dates therein, subject to normal year end audit adjustments and the absence of footnotes. The Financial Statements are in accordance with the books and records of the Company.

(b) Except as set forth on Schedule 5.13 or as contemplated by this Agreement, or in connection with the Amended and Restated Certificate of Incorporation, this Agreement or the other Transaction Documents, since the Balance Sheet Date, there has not been:

(1) any declaration, setting aside or payment of any dividend or other distribution with respect to any shares of capital stock of the Company or any repurchase, redemption or other acquisition by the Company of any outstanding shares of its capital stock of the Company;

(2) any amendment of any term of any outstanding security of the Company;

(3) any transaction or commitment made, or any contract, agreement or settlement entered into, by (or judgment, order or decree affecting) the Company relating to its assets or business (including the acquisition or disposition of any material amount of assets) or any relinquishment by the Company of any contract or other right, other than transactions, commitments, contracts, agreements or settlements (excluding settlements of litigation and tax proceedings) in the ordinary course of business or those contemplated by this Agreement;

(4) any (A) grant of any severance or termination pay to (or amendment to any such existing arrangement with) any director, officer or employee of the Company, (B) entering into of any employment, deferred compensation, supplemental retirement or other similar agreement (or any amendment to any such existing agreement) with any director, officer or employee of the Company, (C) increase in, or accelerated vesting and/or payment of, benefits under any existing severance or termination pay policies or employment agreements or (D) increase in or enhancement of any rights or features related to compensation, bonus or other benefits payable to directors, officers or senior employees of the Company, in each case, other than in the ordinary course of business consistent with past practice; or

(5) any material tax election made or changed, any audit settled or any amended tax returns filed.

5.14 No Undisclosed Material Liabilities. As of the date of this Agreement, there are no liabilities of the Company of any kind whatsoever, whether interest-bearing indebtedness, or liabilities accrued, contingent, absolute, determined, determinable or otherwise, other than liabilities:

(a) reflected in the Financial Statements;

(b) disclosed on Schedule 5.14 hereto;

(d) under this Agreement, or connected herewith, in the other Transaction Documents or the Amended and Restated Certificate of Incorporation.

5.15 Litigation. There is no action, suit, investigation or other proceeding pending against, or to the knowledge of the Company, threatened against or affecting, the Company or any of its properties or to the knowledge of the Company any of its officers or directors before any court or arbitrator or any Governmental Entity. To the knowledge of the Company, there are no facts that would cause a reasonable person to believe that such a proceeding would likely result.

5.16 Taxes. The Company has properly filed all federal, foreign, state, local, and other tax returns and reports which are required to be filed, which returns and reports were properly completed and are true and correct in all material respects, and all taxes, interest, and penalties due and owing have been timely paid. There are no outstanding waivers or extensions

of time with respect to the assessment or audit of any tax or tax return of the Company, or claims now pending or matters under discussion with any taxing authority in respect of any tax of the Company.

5.17 Employee Matters.

(e) comply with all applicable laws, rules and regulations of all Governmental Entities; and

(f) maintain proper books of record and account which present fairly in all material respects its financial condition and results of operations and make provision on its financial statements for all such proper reserves as in each case are required in accordance with GAAP.

10.5 Authorized and Reserved Common Stock and Series D Preferred Stock. The Company agrees to take and to cause to be taken all action necessary to assure that a sufficient quantity of Series D Preferred Stock is timely authorized and reserved for issuance as dividends on the Series D Preferred Stock and upon exercise of the Warrants by the holders thereof in accordance with the terms thereof, and to assure that a sufficient quantity of Common Stock is timely authorized and reserved for issuance to accommodate conversion of Series D Preferred Stock (including Series D Preferred Stock issued in the future and issued as dividends on Series D Preferred Stock and upon exercise of the Warrants by the holders thereof in accordance with the terms thereof). All such shares of Common Stock and Series D Preferred Stock so issuable, and the Warrant Shares, when paid for in accordance with the Warrants, shall, after being issued, be duly and validly issued, fully paid and nonassessable and free of all Taxes and Encumbrances. The Company shall take all action as may be necessary to assure that all such shares of Series D Preferred Stock and Common Stock may be so issued without violation of any laws or governmental regulations.

10.6 Designation of Directors. The Company shall use its best efforts to cause any directors designated by the Purchasers as provided in the Stockholders’ Agreement to be elected to the board of directors of the Company, in accordance with the terms of the Stockholders’ Agreement.

10.9 Qualification to Conduct Business. The Company shall be duly qualified at all times to do business as a foreign corporation and is and will continue to be in good standing in each jurisdiction where the nature of the property owned or leased by it or the nature of the business conducted by it makes such qualification necessary, except where the failure to be so qualified would not have a Material Adverse Effect.

10.10 Future Option Plans. The Company shall cause any equity incentive plan adopted after the Closing Date to provide, in form reasonably satisfactory to the Qualified Purchasers, that any increase, at any time, in the aggregate ownership of securities of the Company by any Person who is a stockholder of the Company on the Closing Date (and immediately after giving effect to the Closing) and any such Person’s Affiliates, in each case, other than active operating companies, shall be exempted from the definition therein of a “Change in Control” (or any like term).

10.11 Purchaser Obligation to Maintain Confidentiality. Except as otherwise required by law, each Qualified Purchaser and its Permitted Transferees to whom disclosures are made by the Company pursuant to Section 10.1 (the “Recipient”) shall not, and shall cause each of its directors, officers, employees, agents, and representatives (collectively, the “Recipient Representatives”) not to disclose the Confidential Information (as defined in this Section 10.11) to any Person or entity other than the Recipient Representatives.

10.13 Termination of Covenants. Except for the provisions of Section 10.11, all the provisions set forth in this Section 10 shall automatically terminate, and be of no further force or effect, immediately upon the consummation of a Qualified Public Offering (as defined in the Amended and Restated Certificate of Incorporation as in effect on the date hereof).
