THE STOCK PURCHASE

SECTION 2.01 The Transaction.

(a) Subject to the terms and conditions of this Agreement, Stockholders will sell to Natus, and Natus will purchase from Stockholders, 25,000 shares of Common Stock of the Company, par value $1 per share (the “Shares”), which Shares represent all of the issued and outstanding shares of capital stock of the Company.

(b) The purchase price for the Shares shall consist of (i) a cash payment at Closing of $16,556,378.12 (less the Escrow Cash), and (ii) additional cash payments, if any, payable to Stockholders as further provided in subsection (c) below.

(c) Natus shall pay to the Stockholders, collectively and in the aggregate, the amounts set forth below as determined by future Cool Cap Revenue in the respective calendar years listed below:

(i) 2007. For each full dollar of Cool Cap Revenue in 2007 in excess of $500,000, Natus shall pay Stockholders $0.63456, provided that the maximum amount that Natus shall pay Stockholders for Cool Cap Revenue in 2007 shall be $507,648, regardless of the Cool Cap Revenue for such year.

(ii) 2008. For each full dollar of Cool Cap Revenue in 2008 in excess of $1,000,000, Natus shall pay Stockholders $0.52881, provided that the maximum amount that Natus shall pay Stockholders for Cool Cap Revenue in 2008 shall be $846,080, regardless of the Cool Cap Revenue for such year.

(iii) 2009. For each full dollar of Cool Cap Revenue in 2009 in excess of $2,000,000, Natus shall pay Stockholders $0.39661, provided that the maximum amount that Natus shall pay Stockholders for Cool Cap Revenue in 2008 shall be $1,269,120, regardless of the Cool Cap Revenue for such year.

Any payment due pursuant to subsection (i) above shall be made on, or at the discretion of Natus before, March 21, 2008, pursuant to subsection (ii) above shall be made on, or at the discretion of Natus before, March 23, 2009, and pursuant to subsection (iii) above shall be made on, or at the discretion of Natus before, March 22, 2010. Such payment(s), if any, shall be made by wire transfer to an account designated in advance by Stockholders, and shall be accompanied by a certificate of the chief financial officer or controller of Natus certifying on behalf of Natus as to the amount of Cool Cap Revenue for the respective year. On at least thirty (30) days’ prior written notice from Stockholders to Natus given within ninety (90) days after Stockholders’ receipt of any such payments, Stockholders shall have a right to audit the books and records of Natus to verify Cool Cap Revenue for the latest calendar year end. The parties intend the

payments (set forth in subsections (i) through (iii) above) to qualify for installment sale reporting under § 453 of the Code. Such payments shall be treated as imputed interest to the extent required by the Code.

If the maximum payment in respect of Cool Cap Revenue is not earned in either of 2007 or 2008, such unearned amount shall not in any way increase the amount of payment in respect of Cool Cap Revenue in any subsequent year. By way of example, if Cool Cap Revenue is $1,000,000 in 2007 and $3,000,000 in 2008, then Natus shall pay Stockholders $317,280 in respect of Cool Cap Revenue in 2007 and $846,080 in respect of Cool Cap Revenue in 2008.

Natus shall use reasonable and good faith business efforts to obtain all governmental approvals for the sale of the Cool Cap Product and thereafter to promote, manufacture, market and sell the Cool Cap Product. In the event that Natus sells to a third party the Cool Cap Product, whether directly or by way of sale of a subsidiary that owns the right to produce and sell the Cool Cap Product, then within thirty days following such sale, Natus shall pay to Stockholders the full amount of any additional cash payments that Stockholders may be eligible to receive under this subsection (c) in respect of sales occurring in years that have not yet been completed as of the date of such sale.

For purposes of this Agreement, “Cool Cap Revenue” for any year shall be the amount of revenue recognized by Natus in its audited annual financial statements for the respective fiscal year from the sales of the Cool Cap Product in such year by Natus or any subsidiary of Natus. For purposes of this Agreement, “Cool Cap Product” shall mean a device developed by the Company for treating hypoxic ischemic encephalopathy in term newborns, FDA reference number P040025, including any design changes, or new models and improvements effecting either hardware or software, or derivative products that may be developed based solely on the Cool-Cap® or any other intended uses of the Cool-Cap® and its derivative products that may be approved by the FDA in the future. Natus hereby covenants to Stockholders that the revenue set forth in Natus’ audited annual financial statements for 2007, 2008 and 2009 shall be reported in accordance with GAAP consistently applied over the periods presented. Cool Cap revenue for any fiscal year shall also include the amount of revenue from the sale of the Cool Cap Product recognized in such year by any person who has licensed from Natus or one of its subsidiaries the right to sell the Cool Cap Product, and for this purpose the amount of such revenue reported by such licensee to Natus, or one of its subsidiaries, shall be deemed to be the amount of such revenue recognized by such licensee; provided that if the amount of such revenue is subsequently adjusted pursuant to any audit right, correction-of-mistake or other provision of any agreement between Natus, or one of its subsidiaries, and any such licensee, then the amount of revenue as so adjusted shall be deemed to be the amount of revenue recognized by such licensee, and Natus shall pay to Stockholders any additional amount due if such adjustment increases the amount of such revenue and Stockholders shall repay to Natus any amount of overpayment that was made if such adjustment decreases the amount of such revenue.

SECTION 2.02 Closing.

The closing (“Closing”) of the Transaction shall take place simultaneously with the execution of this Agreement on October 16, 2006 at the offices of Fenwick & West LLP, 801 California Street, Mountain View, California, or at such other time and place as the parties shall

SECTION 8.03 Limitations.

(a) Recovery from the Escrow Cash shall be the sole and exclusive remedy under this Agreement for the matters listed in the foregoing clauses (a) – (d) of Section 8.02, except in the case of (i) fraud, willful breach or intentional misrepresentation by the Company or any subsidiary, (ii) any failure of any of the representations and warranties contained in Sections 3.03, 3.10(j), 3.14 (with respect to representations and warranties in Section 3.14 pertaining to matters of Federal and Washington State income taxes) and 3.15 to be true and correct as aforesaid, or (iii) the matters set forth in clause (d) of Section 8.02. In the case of (i) fraud,

willful breach or intentional misrepresentation by Stockholders, (ii) any failure of any of the representations and warranties contained in Sections 3.03, 3.10(j), 3.14 (with respect to representations and warranties in Section 3.14 pertaining to matters of Federal and Washington State income taxes) and Section 3.15 to be true and correct as aforesaid, or (iii) the matters set forth in clause (d) of Section 8.02, after Natus has exhausted or made claims upon all amounts of Escrow Cash (after taking into account all other claims for indemnification from the Escrow Cash made by Natus), Stockholders shall be liable for the amount of any Damages resulting therefrom; provided, however, that (A) with respect to (i) fraud, willful breach or intentional misrepresentation by Stockholders and (ii) any failure of any of the representations and warranties contained in Sections 3.03, 3.10(j), 3.14 (with respect to representations and warranties in Section 3.14 pertaining to matters of Federal and Washington State income taxes) to be true and correct, such liability shall be limited to the aggregate amount paid or payable to Stockholders pursuant to Section 2.01 and (B) with respect to (i) any failure of any of the representations and warranties contained in Section 3.15 to be true and correct or (ii) the matters set forth in clause (d) of Section 8.02, such liability shall be limited to $5,000,000. In the event that the Stockholders are able to obtain insurance on behalf of the Company and Natus after the Closing which Natus reasonably determines fully protects Natus and the Company to the same extent as the indemnification provided hereunder by Stockholders against (i) any Damages relating to any failure of any of the representations and warranties contained in Section 3.15 to be true and correct and (ii) the matters set forth in clause (d) of Section 8.02, Natus will then agree that recovery from the Escrow Cash shall be its sole and effective claim under this Agreement (other than access to the insurance so provided by Stockholders) for the matters described in (i) and (ii) of this sentence.

(b) The Natus Indemnified Persons may not receive any Escrow Cash in respect of any claim for indemnification under this Article VIII unless and until Damages in an aggregate amount greater than $100,000 have been incurred, paid or properly accrued by Natus Indemnified Persons, and if Damages greater than $100,000 have been so incurred, paid or properly accrued, the Natus Indemnified Persons shall be entitled to receive Escrow Cash in indemnification therefore without regard to such $100,000 threshold; provided, however, that this sentence shall not limit a Natus Indemnified Person’s right to recover for any failure of any of the representations and warranties contained in Sections 3.03, 3.10(j) and 3.14 (with respect to representations and warranties in Section 3.14 pertaining to matters of Federal and Washington State income taxes).

SECTION 8.04 Notice of Claim.

As used herein, the term “Claim” means a claim for indemnification of Natus or any other Natus Indemnified Person for Damages under this Article VIII. Natus may give notice of a Claim under this Agreement, whether for its own Damages or for Damages incurred by any other Natus Indemnified Person, and Natus shall give written notice of a Claim executed by an officer of Natus (a “Notice of Claim”) to the Stockholders (with a copy to the Escrow Agent if the Claim involves recovery against the Escrow Cash) promptly after Natus becomes aware of the existence of any potential claim by an Natus Indemnified Person for indemnification from Stockholders under this Article VIII, arising from or relating to:

(a) any matter specified in Section 8.02; or

(b) the assertion, whether orally or in writing, against Natus or any other Natus Indemnified Person of a claim, demand, suit, action, arbitration, investigation, inquiry or proceeding brought by a third party against Natus or such other Natus Indemnified Person (in each such case, a “Third-Party Claim”) that is based on, arises out of or relates to any matter specified in Section 8.02.

The period during which claims may be initiated (the “Claims Period”) for indemnification from the Escrow Cash shall commence at the Closing Date and terminate at the one-year anniversary of the Closing Date. The Claims Period for indemnification from and against Damages arising out of, resulting from or in connection with (i) fraud, willful breach or intentional misrepresentation by the Company or any Company subsidiary, (ii) any failure of any of the representations and warranties contained in Sections 3.03, 3.14 (with respect to representations and warranties in Section 3.14 pertaining to matters and Federal and Washington State income taxes) and Section 3.15 to be true and correct as aforesaid, or (iii) the matters set forth in clause (d) of Section 8.02, shall commence at the Closing Date and terminate upon the expiration of the applicable statute of limitations. Notwithstanding anything contained herein to the contrary, any Claims for Damages specified in any Notice of Claim delivered to Stockholders prior to expiration of the applicable Claims Period with respect to facts and circumstances existing prior to expiration of the applicable Claims Period shall remain outstanding until such Claims for Damages have been resolved or satisfied, notwithstanding the expiration of such Claims Period. Until the expiration of the applicable Claims Period, no delay on the part of Natus in giving Stockholders a Notice of Claim shall relieve Stockholders from any of its obligations under this Article VIII unless (and then only to the extent that) Stockholders are materially prejudiced thereby.

SECTION 8.05 Defense of Third-Party Claims.

(a) Natus shall determine and conduct the defense or settlement of any Third-Party Claim , and the costs and expenses incurred by Natus in connection with such defense or settlement (including reasonable attorneys’ fees, other professionals’ and experts’ fees and court or arbitration costs) shall be included in the Damages for which Natus may seek indemnification pursuant to a Claim made by any Natus Indemnified Person hereunder.

(b) Stockholders shall have the right to receive copies of all pleadings, notices and communications with respect to the Third-Party Claim to the extent that receipt of such documents by Stockholders does not affect any privilege relating to the Natus Indemnified Person and may participate in, but not to determine or conduct, any defense of the Third-Party Claim or settlement negotiations with respect to the Third-Party Claim.

(c) No settlement of any such Third-Party Claim with any third party claimant shall be determinative of the existence of or amount of Damages relating to such matter, except with the consent of Stockholders, which consent shall not be unreasonably withheld, conditioned or delayed and which shall be deemed to have been given unless Stockholders shall have objected within 15 days after a written request for such consent by Natus. In the event that Stockholders has consented to any such settlement, Stockholders shall not have any power or authority to object under any provision of this Article VIII to the amount of any claim by or on behalf of any Natus Indemnified Person against the Escrow Cash or Stockholders for indemnity with respect to such settlement.

SECTION 8.06 Contents of Notice of Claim.

Each Notice of Claim by Natus given pursuant to Section 8.04 shall contain the following information:

(a) that Natus or another Natus Indemnified Person has directly or indirectly incurred, paid or properly accrued (in accordance with GAAP) or, in good faith, believes it shall have to directly or indirectly incur, pay or accrue (in accordance with GAAP), Damages in an aggregate stated amount arising from such Claim (which amount may be the amount of damages claimed by a third party in an action brought against any Natus Indemnified Person based on alleged facts, which if true, would give rise to liability for Damages to such Natus Indemnified Person under this Article VIII); and

(b) a brief description, in reasonable detail (to the extent reasonably available to Natus), of the facts, circumstances or events giving rise to the alleged Damages based on Natus’s good faith belief thereof, including the identity and address of any third-party claimant (to the extent reasonably available to Natus) and copies of any formal demand or complaint, the amount of Damages, the date each such item was incurred, paid or properly accrued, or the basis for such anticipated liability, and the specific nature of the breach to which such item is related.

SECTION 8.07 Resolution of Notice of Claim.

Each Notice of Claim given by Natus shall be resolved as follows:

(a) Uncontested Claims. If, within 15 business days after a Notice of Claim is received by Stockholders, Stockholders does not contest such Notice of Claim in writing to Natus as provided in Section 8.07(b), Stockholders shall be conclusively deemed to have consented, to the recovery by the Natus Indemnified Person of the full amount of Damages specified in the Notice of Claim in accordance with this Article VIII, including the forfeiture of Escrow Cash to the extent of such Damages, and, without further notice, to have stipulated to the entry of a final judgment for damages against Stockholders for such amount in any court having jurisdiction over the matter where venue is proper.

(b) Contested Claims. If Stockholders gives Natus written notice contesting all or any portion of a Notice of Claim (a “Contested Claim”) (with a copy to the Escrow Agent) within the 15 business day period specified in Section 8.07(a), then such Contested Claim shall be resolved by either (i) a written settlement agreement executed by Natus and Stockholders (a copy of which shall be furnished to the Escrow Agent) or (ii) in the absence of such a written settlement agreement within 30 business days following receipt by Natus of the written notice from Stockholders, by binding litigation between Natus and Stockholders in accordance with the terms and provisions of Section 8.07(c).

(c) Litigation of Contested Claims. Either Natus or Stockholders may bring suit in the courts of the State of Washington and the Federal courts of the United States of America located within the State of Washington to resolve the Contested Claim. Regardless of which

party brings suit to resolve a matter, Natus shall bear the burden of proof by a preponderance of the evidence that Natus or other Natus Indemnified Persons are entitled to indemnification pursuant to this Article VIII. The decision of the trial court as to the validity and amount of any claim in such Notice of Claim shall be nonappealable, binding and conclusive upon the parties to this Agreement and the Escrow Agent shall be entitled to act in accordance with such decision and make or withhold payments out of the Escrow Cash in accordance therewith. Judgment upon any award rendered by the trial court may be entered in any court having jurisdiction. For purposes of this Section 8.07(c), in any suit hereunder in which any claim or the amount thereof stated in the Notice of Claim is at issue, the Court shall determine which party is the non-prevailing party. The non-prevailing party to a suit shall pay its own expenses and the expenses, including attorneys’ fees and costs, reasonably incurred by the other party to the suit.

SECTION 8.08 Release of Remaining Escrow Cash.

Within five business days following the expiration of the Claims Period, Natus shall instruct the Escrow Agent to deliver all of the remaining Escrow Cash (if any) in excess of any amount of Escrow Cash that is necessary to satisfy all unresolved, unsatisfied or disputed claims for Damages specified in any Notice of Claim delivered to Stockholders before the expiration of the Claims Period as follows: there shall be delivered to the Stockholders an amount equal to 0.846080 times the amount of such remaining Escrow Cash and there shall be delivered to the Company (or to such other party as Escrow Holder shall be directed in writing by Natus and the Company), the balance of such remaining Escrow Cash. If any Claims are unresolved, unsatisfied or disputed as of the expiration of the Claims Period, then the Escrow Agent shall retain possession and custody of that amount of Escrow Cash that equals the total maximum amount of Damages then being claimed by Natus Indemnified Persons in all such unresolved, unsatisfied or disputed Claims, and as soon as all such Claims have been resolved, the Escrow Agent shall deliver to the Stockholders 84.6080% of the remaining Escrow Cash (if any) not required to satisfy such Claims and shall deliver the balance of any remaining Escrow Cash to the Company (or to such other party as Escrow Holder shall be directed in writing by Natus and the Company). The parties intend the Escrow Cash to qualify for installment sale reporting under § 453 of the Code. Distributions from Escrow Cash shall be treated as imputed interest to the extent required by the Code.

SECTION 8.09 Tax Consequences of Indemnification Payments.

All payments (if any) made to any Natus Indemnified Person pursuant to any indemnification obligations under this Article VIII will be treated as adjustments to the purchase price for tax purposes and such agreed treatment will govern for purposes of this Agreement, unless otherwise required by law.
