NOW, THEREFORE, THE PARTIES HERETO AGREE AS FOLLOWS:

SECTION 1

SALE AND PURCHASE OF STOCKS; TRANSFER OF STOCKS;

1.1	Stocks owned by Sellers

Each of the Sellers hereby sells its Stocks in the Company to the accepting Purchaser as outlined in EXHIBIT 1.1.a (including the number of the stocks certificates to be transferred and endorsed to the Purchaser at the Closing as defined in Section 9.1) (the Sold Stocks) with all dividend and dividend drawing rights (Gewinn- und Gewinnbezugsrechte) relating to the period as from 1 January 2010 (the Effective Date) and all subscription and other rights pertaining to each sold Stock (the Sale and Purchase). EXHIBIT 1.1.b lists all owners of Stocks after completion (dingliche Erfüllung) of the Sale and Purchase (the Completion).

1.2	Stocks owned by Minorities

As from Completion, the Purchaser will own 100% of the Stocks. If this was not the case, the following subsections 1.2 b to g would apply:

Therefore, as soon as possible, at the latest however within a period of 4 months as from Completion the Sellers shall approach such shareholders who own the remaining outstanding Stocks which have not already been sold and transferred to the Purchaser with effect as at Completion (the Minorities) in order to achieve the acquisition by the Purchaser of 100% of the Stocks.

The Parties agree that they shall cooperate in good faith to achieve the Purchaser to acquire 100% of the Stocks. The Sellers Representative shall negotiate the amounts of purchase prices to be paid to the Minorities for their Stocks. The Parties further agree that purchases prices to be agreed with the Minorities in the 4 months period according to Section 1.2 b) shall mirror the purchase price terms and conditions of this Agreement but that the Minorities shall have no information right against either the Purchaser or AdnaGen. The Sellers Representative shall not negotiate purchase prices (pro rated) in excess of the stocks price to be paid to the Sellers under this Agreement unless approved by the Purchaser. The same shall apply mutatis mutandis to any purchase price structure or payment term that differs from the purchase price structure or payment terms agreed in this Agreement: the Sellers Representative shall in particular not negotiate one time payments for the Stocks of the Minorities that are in excess of the (pro rated) First Purchase Price unless approved by the Purchaser.

If it turns out that the acquisition of 100% of the Stocks by the Purchaser cannot be accomplished within the time period according to Section 1.2.b), the Parties agree – at the option of the Purchaser, and such option to be exercised within 4 months as from the end of the time period referred to in Section 1.2.b) - to initiate a squeeze out procedure so that the Purchaser can acquire the outstanding Stocks as a result of the squeeze out. To the extent legally permissible the Sellers Representative shall control and all Parties shall actively support the squeeze out, if such procedure is required. The Purchaser shall have the right to object to the advisors and the actions being suggested by the Sellers Representative.

All costs and expenses of the Purchaser and/or AdnaGen caused by a squeeze out procedure shall be borne equally by the Sellers (50%) and the Purchaser (50%) up to the Capped Cost Amount, including but not limited to (i) costs caused by or related to corporate law measures (including notary fees and expenses), (ii) costs and expenses of accountants, and (iii) costs and expenses caused by courts fees, accountant and legal fees, in particular all costs and expenses caused in case of a procedure under the Corporate Proceedings Act (Spruchverfahrengesetz) or in case of contest action (Anfechtungs- oder Nichtigkeitsklage).The amount of the Capped Cost Amount shall be EUR 200,000. Any amounts in excess of the Capped Cost Amount shall be borne in total by the Sellers but not by the Purchaser nor by MBG, understood in this context that MBG is not a party to this Agreement and that the before reference to MBG is based on a request of MBG and for clarification purposes only.

The Sellers shall bear the purchase price agreed between the Sellers and the Minorities or cash compensation resulting from the squeeze-out or any other compensation to be paid to the Minorities and agreed between the Parties as consideration for the Purchaser acquiring all Stocks from the Minorities. For the avoidance of doubt, Section 1.2 c) shall equally apply to any purchase price or voluntary compensation referred to in the preceding clause of this Section 1.2.f).

For the avoidance of doubt, the following would only apply if the Purchaser did not acquire 100% of the Stocks: for the purpose of securing the payment of the purchase prices and compensations owing to the Minorities, the Agent shall keep and allocate 2.5% of the First Purchase Price (as defined in Section 2.1) to the acquisition by the Purchaser of the Stocks from the Minorities (the Reserve Amount). The Agent shall pay from the Reserve Amount to the Minorities on behalf of the Purchaser the relevant amounts (as the case may be, either the purchase prices agreed or the cash compensation determined). If and to the extent that the Reserve Amount should not be sufficient to settle all purchase prices or cash compensations payable to Minorities, the Sellers shall be liable for the difference (the Payment Difference), however understood that the Purchaser shall be obliged to pay the Payment Difference to the Minorities to achieve the timely transfer of the Stocks upon complete payment of the purchase price or compensation. The Payment Difference being financed respectively by the Purchaser shall be set off against (or deducted from) any claims of the Sellers for a Second or Third Purchase Price or Milestone Payments.

1.3	Transfer of Stocks owned by Sellers

The Sellers and the Purchaser are hereby in agreement, that the title to the Sold Stocks shall, subject to the receipt of the First Purchase Price and the approval of the Supervisory Board, pass to the Purchaser (dingliche Übertragung) at the Closing Date, and that the actual transfers shall be effected by endorsement and handing over of the relevant stock certificates. Only for reasons of utmost precaution, each of the Sellers hereby assigns and transfers to the Purchaser, who hereby accepts such assignments and transfers, the Sold Stocks and all its membership rights and other rights pertaining to the Sold Stocks for the period as from the Effective Date whilst such assignment and transfer is conditional upon the receipt of the First Purchase Price and the approval of the Supervisory Board.

1.4	Steering Committee; Cash injections

A steering committee (Steering Committee) shall be formed immediately after Closing to function as an advisory / oversight committee on all Budget, Milestone and Target related topics. The Steering Committee will be comprised of no less than 4 members and will be equally split between the Purchaser’s and Seller’s representatives. Each of Purchaser and Sellers will appoint its respective two representatives at the Closing Date.

The Parties agree that the role of the Steering Committee is advisory only unless explicitly otherwise agreed in this Agreement.

A business plan of the Company being set up by the Sellers is attached as Exhibit 1.4.c (the Budget). The Budget sets out the expected revenues and costs of the Company for the period ending 31 August 2011.

The Purchaser shall be obliged to provide the Company immediately following Completion with a cash injection in an amount of EUR 500,000 (Cash Injection 1).

The Cash Injection 1 shall fund the business operations (based on the costs as per Budget) for a period of 6 months as from Completion to the extent that the Company’s actual cash-in revenues are less than budgeted cash-out costs.

For the period starting with the seventh month as from Completion and up to and including 31 August 2011, the Purchaser shall provide the Company with a further cash injection in the amount of up to EUR 500,000 (Cash Injection 2) if the Steering Committee determines that the total cash “net income / loss” of the Company as per Budget for the relevant months minus the amount of available cash (or cash equivalents) at the Company is not sufficient to enable the Company to achieve the Budget.

For the period as from 1 September 2011 and ending 36 months as from Completion, the Steering Committee shall mutually agree on 6 months budgets (each a New Budget), and the last New Budget covering the remaining term. The Steering Committee shall agree on New Budgets at least six months in advance to the relevant term of a New Budget, i.e. the Steering Committee shall agree on the New Budget for the period starting 1 September 2011 and ending 29 February 2012 on 28 February 2011 at the latest. The Steering Committee shall further determine the amount of the relevant Additional Cash Injection, which will not be higher than EUR 500.000 per any 6 months period. If it turns out during the time period between agreeing on a New Budget and its coming into effect that the projections forming the basis of the New Budget cannot be fulfilled, the management of the Company shall have the right, until 4 weeks before the New Budget enters into effect, to contact the Steering Committee and ask for a revision of the New Budget. If the Steering Committee agrees with the request of the Company’s management the New Budget will enter into effect as amended by the Steering Committee.

The Purchaser shall provide the Company for the term of a New Budget with the funding agreed for that term by the Steering Committee (Additional Cash Injections). It is understood that Cash Injections shall not be provided just for the purpose of being in the Company’s bank account but that Cash Injections shall be provided timely in reasonable tranches when required in line with the Budget (or New Budget(s)).

The following applies with respect to the determination of amounts of cash injections and payments:

(1)

The general principle and underlying rational shall be the following: the Company shall have such funds available that are required to cover “Total Costs” (as relevant cash-outs in the period rather than as accounted costs or accruals) as per New Budget, and such funds shall comprise of all actual revenues achieved by the Company, its available cash (or cash equivalents) and, if required, Additional Cash Injections. All Additional Cash Injections (and Conflict Cash Injections) are in any case subject to the Limitations. Ideally, the Company will achieve break even (on a cash basis) as forecasted in the Budget, and in such case there will be no further Additional Cash Injections (or Conflict Cash Injection) as the Company can finance then its operations by using own cash.

(2)

The use of the Additional Cash Injections (or Conflict Cash Injection) and the relevant amount of such injection shall be in any case subject to the following regulations and limitations (the Limitations): in no event an installment of a cash injection shall exceed EUR 500,000, the maximum amount of a cash injection within each 6 months interval shall be an amount of EUR 500,000, and all Additional Cash Injections shall be spent only in line with and on the basis of the New Budget. The Steering Committee shall not be entitled to amend or waive the Limitations. For the avoidance of doubt, the management of the Company shall be free to operate the Company’s business within the framework of the New Budget. If necessary, the management of the Company may decide that budgeted amounts shall be allocated to other projects than as anticipated in the New Budget, it being understood if such is the case there is no entitlement for requesting financing for cancelled projects. The management of the Company must however inform the Steering Committee of any such changes.

(3)

The Purchaser may elect the form of the Cash Injection 1, Cash Injection 2 or Additional Cash Injection or Conflict Cash Injection, i.e. either in the form of an equity contribution, subordinated loan or a combination thereof.

(4)

The Cash Injection 1, the Cash Injection 2 and the Additional Cash Injections (and Conflict Cash Injections) shall enable the Sellers to achieve the Second and Third Purchase Price and Milestone Payments by the Company being able to utilize funds as per the Budget (or New Budgets) with the consequence that cash injections made in form of loans shall be disregarded for purposes of determining the “No Debt” criteria according to Section A.2 of EXHIBIT 2.2 and as further specified in that Exhibit. The Sellers confirm that the maximum amounts of the cash injections are calculated realistically with view to that objective.

Purchaser and Sellers agree that the Budget does not provide for the performance of AdnaGen of the following activities:

- [**Redacted**]

(the Additional Activities).

The Purchaser shall use commercially reasonable efforts to pursue the Additional Activities. The following process shall apply, either formally or informally: The Company, the Purchaser (or its representative) shall update the Steering Committee either on a regular basis or following a request of the status of the achievements of the Additional Activities and/or allocated efforts/resources therefore.

The Purchaser and Sellers Representative shall jointly prepare a detailed plan on activities to be pursued and resources (through funding, allocation of personnel or otherwise) to be used in order to achieve the target of [**Redacted**] (the Plan). Such Plan shall be discussed with the Steering Committee and the Sellers Representative and the Purchaser (or its representative(s) and, if acceptable to the members of the Steering Committee, agreed upon, and, if required, amended from time to time following discussion with the Steering Committee. The Sellers acknowledges that external resources to Alere shall be used carefully and in line with industry practices- it is understood that, in any event, not more than € [**Redacted**] would be allocated to external service fees to pursue the target.

The Purchaser acknowledges that reaching the target of [**Redacted**] may involve the employment of external resources to Alere-group, although it is also acknowledged that the Alere-group has a good regulatory group to follow up on these items and provide the necessary input. The implementation of the activities of such Plan may be led by Alere, its representatives or the AdnaGen management as deemed appropriate. For the assessment of the Purchaser's commercially reasonable efforts (as per the above second para. of this section 1.4.j), the implementation of the activities plan is relevant, not the result of each activity, it being understood that, if based on recomme ndations received either from the Alere-group regulatory department and/or external consultants, a certain activity is advised not to be taken then Purchaser or its representative shall be allowed, in its own discretion, after discussion with the Steering Committee, to reject to implement such activity or not to proceed with the execution of certain actions (without any sanction becoming applicable).

All injections shall be paid to a bank account of the Company as notified by its management board to the Purchaser.

If the Steering Committee cannot mutually agree on a New Budget or thereby on the amount of Additional Cash Injections, the following shall apply:

(1)

Either the Purchaser or the Sellers Representative or both shall declare by written notice (no email but by registered letter with a fax in advance) to the respective other Party a status of conflict that starts as from the beginning of the term of a New Budget (or Budget) that cannot be agreed to (the Conflict). If no Conflict is declared, the obligations of the Purchaser to provide Additional Cash Injections cease as from the end of the term of the then prevailing budget.

(2)

If no agreement is reached on a New Budget prior to expiration of the term of the then prevailing budget, for the term of a Conflict the last prevailing New Budget (or Budget for the period March to August 2011 in case no New Budget can be agreed for the period starting 1 September 2011) shall continue, i.e. the amount of Additional Cash Injections shall be the amount of the Additional Cash Injection as per the last budgeted period, and shall be due and payable in the same manner as the prevailing Additional Cash Injection (the Conflict Cash Injection). The Conflict Cash Injection shall be subject to the Limitations and the following reductions and adjustments (the Adjustments):

If the actual cash-in revenues achieved by the Company in the relevant 6 months period (Actual Revenues) are higher than or equal to its actual cash-out costs of the relevant 6 months period (Actual Costs), no Conflict Cash Injection shall fall due. The underlying rational is that, unless budgeted or mutually agreed by the Steering Committee, the Purchaser shall not finance the Company if the Company can cover its cash-out costs by cash-in revenues.

ii.

On the costs side the underlying rational is that the Purchaser shall not be obliged to finance the Company’s development based on a cost increase unless budgeted or mutually agreed by the Steering Committee.

iii.

The Adjustments shall be calculated for each relevant 6 months period by taking into account cash-in revenues to be achieved and cash-out costs to be caused in the relevant period.

iv.

The Adjustment shall be calculated by the Sellers with the support of the Company’s management and notified to the Purchaser 30 Business Days prior to a relevant payment date (Payment Notice) by providing all supporting information and calculation materials and the relevant amount of the requested Conflict Cash Injection. If the Sellers miss that deadline for providing the Payment Notice, the obligation of the Purchaser to provide a Conflict Cash Injection for the relevant 6 months period ceases.

The obligations of the Purchaser to provide cash injections shall only create a right of the Sellers under this Agreement but no right or entitlement of the Company nor shall the Company be provided with any protection: the principles of a contract that protects third parties (Vertrag mit Schutzwirkung zugunsten Dritter) or that is for the benefit of a third party (Vertrag zu Gunsten Dritter) shall not apply to this Agreement including the relevant cash injection obligations.

1.5	Consequence of violation of the cash injection obligations

If the Cash Injection 1 or 2 or any of the Additional Cash Injections or Conflict Cash Injections is not provided timely (and timely by calculating a grace period for payment delays of 5 Business Days as from the due date) and despite a reminder of the Sellers Representative following the payment default not paid within 5 business days as from receipt of the reminder to the Company (Delay 1) in the period between Completion and expiration of the Milestone Period (as defined for the Second Purchase Price), the claim for the Second Purchase Price in an amount of USD 10 (ten) million and in addition the claim for the Third Purchase Price in an amount of USD 5 (five) million shall become existent (entstehen), and relevant payments shall become due (fällig) at the time of the Delay 1 and shall be then subject to the payment terms and conditions agreed to in this Agreement regarding the Second and Third Purchase Price.

If any of the Additional Cash Injections or Conflict Cash Injections is not provided timely (and timely by calculating a grace period for payment delays of 5 Business Days as from the due date) and despite a reminder of the Sellers Representative following the payment default not paid within 5 business days as from receipt of the reminder to the Company (Delay 2) in the period (x) as from the expiration of the Milestone Period as defined for the Second Purchase Price and (y) the expiration of the Milestone Period (as defined for the Third Purchase Price), the claim for the Third Purchase Price in an amount of USD 5 (five) million (unless already paid due to a failure pursuant to Section 1.5.a) shall become existent (entstehen), and the relevant payment shall become due (fällig) at the time of the Delay 2 and shall then be subject to the payment terms and conditions agreed to in this Agreement regarding the Third Purchase Price.

If the Sellers can prove that the failure of the Purchaser to comply with its obligations for providing a relevant Additional Cash Injection or Conflict Cash Contribution materially affected the Company and jeopardized therefore materially the possibility of the Sellers to achieve individual Targets agreed in relation to an individual Milestone Payment, the relevant Milestone Payment shall fall due and the relevant payment shall be subject to the payment terms and conditions agreed to in this Agreement regarding a Milestone Payment unless the Purchaser can prove that the achievement of a relevant Target and therefore the achievement of a relevant Milestone Payment was at the time of the payment default improbable assuming the Company acting in the course of normal business and in line with Budget or New Budgets (or based on the amounts of Conflict Cash Contributions in case of a Conflict).

If the Purchaser instructs a bank to transfer the Cash Injection or any Additional Cash Injection to a Company account and the Company receives timely the instructed amount less banking fees or costs being charged by banks involved in the money transfer or less exchange differences, the relevant payment shall be deemed complete and timely and the Purchaser shall make up the difference in due course by transferring the difference to the Company.

During a Conflict, the Purchaser shall provide Conflict Cash Injections as notified to him in the Payment Notice by the Sellers’ Representative, however in no event amounts that do not comply with the Limitations or Adjustments. The Purchaser shall be entitled to review the Payment Notice and the relevant calculation and, if an amount notified to the Purchaser in a Payment Notice is according to its calculation in excess of the Conflict Cash Injection that became due in accordance with his Agreement, the Purchaser shall be entitled to deduct the excess amount from the amount notified to it without triggering a penalty or other consequences, and the Parties shall thereafter in good faith discuss and solve that topic.

4.2	Administration of Breaches

(A) In case of a breach of any Representations, the Sellers Guarantor or, if the Sellers are concerned in relation to a Representation they assume, the Sellers may attempt to remedy the breach (Naturalrestitution). If the Sellers Guarantor, or, as the case may be, the Sellers fail to remedy the breach within a reasonable period of time, such period not to exceed one month after the Sellers Guarantor has received a written and sufficiently detailed notification as to the breach from the Purchaser (the Claim Notification), the Purchaser shall be entitled to claim from the Sellers Guarantor or, as the case may be, the Sellers compensation in cash (Schadensersatz in Geld) pro rata to the Purchaser’s actual shareholding in the Company at the time of the compensation for any actual losses within the meaning of Sec. 249 et seq.

Any liability of the Sellers in connection with Representations shall be excluded or decreased if and to the extent that claims of the Purchaser or the underlying circumstances, respectively, are (i) covered by insurance policies or claims against third parties to the extent such claims against third parties have been collected (at the expense of the Sellers) within 4 months as from the Warranty Notification or (ii) specifically reserved for in the Financial Statements; (iii) have been specifically disclosed to the Purchaser in this Agreement (including its Exhibits); (iv) has been done or omitted to be done with respect to the subject matter of the claim at the request, or with the approval, of the Purchaser; (v) the result of or are increased by the failure of the Purchaser to mitigate damages; (vi) the result of an Act of God or (vii) the result of or is increased by the passing of, or any change in any law, statute, ordinance, rule, regulation or administrative practice of any competent authority after the Signing Date.

4.5	Cooperation

In case of a breach of any Representations (including Tax Representations) and indemnities, which relates to court judgments, public orders or third party claims raised against the Company, the Party or Parties receiving such information shall procure that (i) the Sellers and the Purchaser shall be properly informed, without undue delay, about any claim or proceedings which may give rise to a claim of the Purchaser in relation to the Representations, (ii) no binding declarations shall be made vis-à-vis any court, public authority or third party without the prior written instruction of the Sellers Representative and the Purchaser, (iii) such measures or actions shall be taken or omitted as the Sellers Representative may instruct, at the expense of the Sellers, to avoid, defend, dispute or settle such claim and (iv) for such defense, dispute or settlement action such advisors shall be retained as selected by the Sellers Representative.

4.7	De-minimis / Basket

Claims of the Purchaser under, or in connection with, Representations can only be raised if and to the extent that (i) each individual claim, or a series of similar claims, exceeds EUR [**Redacted**] and (ii) the aggregate amount of claims which can be raised pursuant to lit. (i), exceeds EUR [**Redacted**], in which case the Purchaser shall be entitled to claim the full amount (Freigrenze). The before limitations shall not apply in respect of Representations and related claims relating to (i) the title to Stocks, and (ii), for the avoidance of doubt, Indemnifications.

4.8	Maximum Liability in Case of a Breach of Representations

The maximum liability of the Sellers for all claims of the Purchaser under, or in connection with, the Representations shall be limited to an amount equal to the following percentages of the purchase price/s paid or fallen due under this Agreement: 20% of the First Purchase Price plus 15% of any further purchase prices (i.e. Second, Third and any and all Milestone Payments). The amount of the maximum liability increases therefore from USD 2 million (maximum liability upon First Purchase Price becoming due) if and to the extent that the Second or Third Purchase Price or Milestone Payments are paid or become due, and such increase(s) however, shall have – for the avoidance of doubt –retroactive effect as from Completion onwards and shall therefore increase any claims of the Purchaser in relation to Representations, not depending when such claim has fallen or becomes due or if such claim has already been paid based on or dismissed due to a originally lower maximum amount of liability. For the avoidance of doubt, the Sellers shall in no event be liable to pay more than they have received as purchase prices. The before limitations shall not apply in respect of claims (i) relating to the title to Stocks, (ii) Tax Representations (for the avoidance of doubt as represented by Sellers Guarantor) and (iii), for the avoidance of doubt, Indemnifications (for the avoidance of doubt as given by Sellers Guarantor); for the avoidance of doubt, Section 4.10 (h) shall remain unaffected. Among the Sellers the following shall apply: Sellers Guarantor has confirmed in a separate agreement between the Sellers, the Silent Partnership Seller and the Agent that Sellers Guarantor has no claims for recourse against Seller 2 and Seller 5 unless Seller 2 and Seller 5 are liable under Section 3 of this Agreement.

4.9	Period of Limitation

The period of limitation for all Representations and related claims of the Purchaser relating to the title to shares in the Company shall run until the fifteenth (15) anniversary of the Completion; the period of limitation for all other Representations under this Agreement shall run until 30 June 2013, except for the Tax Representations which shall run until the period indicated in Exhibit 5.8. For the avoidance of doubt, the before limitations shall not apply to Indemnifications.

4.10	Deductions; set-off; bank guarantee

The Purchaser may set-off any claims it has under or in relation to or caused by Representations (including Tax Representations) or Indemnifications or the Payment Difference against the Second and/or Third Purchase Price and/or Milestone Payments, and, for the avoidance of doubt, the payment of any so reduced amount shall constitute the payment of the relevant purchase price.

The before paragraph (a) in relation to a set-off shall not apply to the Representations contained in the Sections 3.2, Sections 3.3 b, e, 3.4, 3.6 excluding lit. e and f, 3.9, and 3.11, . In these cases, a set-off is only permissible if claims of the Purchaser are established by a court or an arbitral court of competent jurisdiction in accordance with Sections 10.11 of this agreement, certified as being final or provisionally enforceable (vorläufig vollstreckbar), ordering the Sellers or the Sellers Guarantor to make payments to the Purchaser. In case of a judgment provisionally enforceable only on security (gegen Sicherheitsleistung), the set-off will only be permissible, if the security has been lodged by the Purchaser.

If the Purchaser declares a set-off in line with the provisions contained in paragraph (a), it may withhold any amounts being subject to the declared set-off, and such shall not constitute a payment default or create any rights of the Sellers, in particular not in relation to the Call Option. The validity of the set-off (including, for the avoidance of doubt, the respective lawful set-off amount, if any) shall then be determined in line with the provisions of this Agreement, and the following shall in particular apply: any amount/s not being validly subject of the set-off shall become due and payable within 10 (ten) Business Days as from the date the subject matter has been established by a court or an arbitral court of competent jurisdiction in accordance with Sections 10.12 of this agreement, certified as being final or provisionally enforceable (vorläufig vollstreckbar), ordering the Purchaser or the Purchaser’s Guarantor to make payments to the Sellers. In case of a judgment provisionally enforceable only on security (gegen Sicherheitsleistung), a payment may only be requested by the Sellers if they have lodged security.

On the Second and the Third Payment Date, the Sellers Guarantor shall deliver to the Purchaser an irrevocable, unconditional bank guarantee on first demand of a first class German or European bank of international standing in the amount of EUR 200,000 substantially in the format attached as Exhibit 4.10.d (Sellers Bank Guarantee) securing any of the Sellers and the Sellers Guarantor’s obligations arising under this Agreement in relation to Sellers’ Tax Representations pursuant to EXHIBIT 3.8 and/or the related Indemnifications. The delivery of Sellers’ Bank Guarantee shall be effected step by step (Zug um Zug) against payment of the relevant purchase price.

If at the time a Milestone Payment falls due the Purchaser has not already been provided by the Sellers with two Sellers’ Bank Guarantees, the Sellers shall provide the Purchaser with the missing Seller’s Bank Guarantee/s prior to the Purchaser effecting a Milestone Payment.

Each Sellers Bank Guarantee shall remain in place up to and including 31 December 2014. The banking fees caused by a Sellers’ Bank Guarantee shall be shared equally between Sellers (50%) and Purchaser (50%).

The Parties agree that at the request of the Sellers the Purchaser shall procure that the Company shall try to trigger a tax audit. The Purchaser shall also be entitled to request the Company to trigger a tax audit.

The Sellers explicitly agree that all Purchaser’s claims for Representations and Indemnifications in general (and therefore also a set-off) shall reduce (or shall have consequences to) claims for the payment of purchase prices though the Sellers (except for the Sellers Guarantor) are under this Agreement only liable for a limited number of Representations. The Sellers (except for the Sellers Guarantor) insofar bear consequences caused by a breach of Representations or of Indemnifications for which they are not liable and all Sellers acknowledge and agree to such concept.

To the extent permitted by law, the Parties agree that all payments made in context with Representations and Indemnifications shall be adjustments to the purchase prices for all Tax purposes.

SECTION 5

INDEMNIFICATIONS

From and after the Completion, the Sellers Guarantor agrees to indemnify (freistellen) (the Indemnification/s) the Company and/or the Purchaser, as the case may be, from any damages referred to and subject to the regulations set forth in EXHIBIT 5. For the avoidance of doubt, the actual amount of compensation owed by the Sellers Guarantor under this Agreement for any claim will not be increased by the fact that Indemnifications and Representations may relate to the same matter or breach (i.e. no double counting of damages).

The Sellers Guarantor shall – as further outlined in Exhibit 5 – in particular indemnify the Company from any and all claims, costs and damages in relation to or caused by claims of [**Redacted**] that were not [**Redacted**], and such indemnification to include in particular to obligate the Sellers Guarantor to pay all costs spent by the Company due to litigation, including fees charged by legal advisors that are in excess of the statutory fee schedule. The Purchaser and the Sellers Guarantor shall negotiate in good faith if and to which extent the indemnification can be limited, considering however that neither the Purchaser nor the Company shall have cash requirements or liabilities with view to [**Redacted**] acting as [**Redacted**] and in context with [**Redacted**] (as outlined in this Agreement), the [**Redacted**] (in particular in context with the [**Redacted**] and all consequences under or caused by that [**Redacted**]) and [**Redacted**] matters.

EXHIBIT 2.2

Second Purchase Price

A.Second Purchase Price

An additional purchase price for the Sold Stocks shall amount up to USD 10 (ten) million (the Target Amount) to be paid at the Second Payment Date (and being subject to the deductions and set-offs and payment mechanisms exclusively set out in this Stock Purchase Agreement including this Exhibit 2.2 and the Transaction Fee Schedule (the Second Purchase Price).]

The Target Amount shall fall due if and when (the Target Date) at any time during the 24 months following Completion (the Milestone Period) AdnaGen achieves the following target figures (together the Milestones) being understood that the Milestones must be fulfilled collectively at the same Target Date for the last 12 trailing months:

Gross Revenues in a total amount of at least EUR [**Redacted**] plus USD [**Redacted**] (the Revenue Milestone) Gross Revenues in either currency exceeding the above minimum face value for a respective currency can be added to the other currency. The split into USD and EURO as above has the sole purpose to assure minimum overall sales in case of material exchange rate fluctuations between the USD and the EURO.

and

Positive Net Income (the Income Milestone)

and

No Debt within the Company at the Target Date and for the last 12 trailing months (the No Debt Milestone).

Gross Revenues shall have the following meaning: total net sales (Umsatzerlöse) calculated according to Sec 275 para. 3 number 1 HGB, proceeds from public grants up to a maximum grant amount of 10% of the Revenue Milestone, license income (royalties or up-front payments) – excluding Category 3 Payments, subject however to the Allocation Option - within the Milestone Period up to and including the Target Date. The Sellers shall have the following option (the Allocation Option): if the Company receives within the Milestone Period payments under Category 3 of Exhibit 2.4 (royalties and up-front payments from a pharmaceutical alliance) (Category 3 Payments), the Sellers Representative can opt within the Milestone Period in writing to attribute all Category 3 Payments received from a pharmaceutical alliance to the Gross Revenues: if the Sellers Representative opts accordingly, the relevant Category 3 Payments will not be considered under Category 3 of Exhibit 2.4. In other words: the Sellers Representative can decide to consider all Category 3 Payments received from a pharmaceutical alliance either in Schedule 2.4 as royalties/up-front payments or – if opted - in Schedule 2.2 as Gross Revenues.

Positive Net Income shall have the following meaning: the total of the net income of the Company achieved within the Milestone Period up to and including the Target Date (Net Income) must amount to at least EUR 1 (in words: One Euro) whilst the Net Income shall be calculated as if the annual net income (Jahresüberschuß in the sense of Sec. 275 para. 3 number 19 HGB would be calculated for the relevant period up to the Target Date excluding, for the avoidance of doubt, (i) any compensation of losses (Verlustausgleiche) under enterprise agreements (Unternehmensverträge) or (ii) loss reducing contributions or (iii) dissolutions of reserves that reduces losses. In addition, the following extraordinary positions (revenues and costs) shall not be considered in the calculation of the Net Income:

cost of changing the legal form of AdnaGen;

additional taxes to be paid by AdnaGen (as costs) or tax savings achieved at the level of AdnaGen (i.e. also in the form of earnings or profits) due to AdnaGen being a member of a corporate income or trade tax unity;

consolidation effects in AdnaGen, if any; and

any change in Net Income arising from a change of the currently applied accounting principles unless required under mandatory law.

No Debt shall have the following meaning: within a period of 12 months prior to the Target Date and at the Target Date, the Company shall not have established (begründet) liabilities in the sense of Sec. 266 para. 3 C. numbers 2, 5, 6, 7 HGB.

As from the transfer of the silent partnerships of Seller 2 and the Partnership Seller to the Purchaser, the relevant silent partnership amounts shall not constitute debt for the purposes of the No Debt definition. The same shall apply to debts that (i) the Purchaser forces the Company to take outside the commercial needs of the Company, or (ii) that are caused by the corporate structuring of the Cash Injection 1, the Cash Injection 2 or an Additional Cash Injection or a Conflict Cash Injection (as defined in the SPA) provided to the Company.

3.	Up to the Second Payment Date plus a grace period of 5 Business Days, the Second Purchase Price shall bear no interest.

The months periods stated above shall cover full calendar months. The Milestone Period shall start on the first day of the month following Completion (Start Date), and the 12 months period shall mean any consecutive 12 months period as from the Start Date up to the expiration of the Milestone Period.

5.	The amount of the Second Purchase Price shall decrease if any of the Milestones is not achieved within the stated periods as follows:

If either the Income or the No Debt Milestone is not achieved (or, for the avoidance of doubt, if both are not achieved), no Second Purchase Price will fall due.

Category 3: Validation of IP; Pharmaceutical Alliances; [**Redacted**] and [**Redacted**].

Category 3 Requirements are:

Creation of a pharmaceutical alliance (i.e. collaboration with enterprises active in the pharmaceutical industry that are not being part of the Alere-group) under which the Company’s IP in the field of [**Redacted**] and [**Redacted**] is validated; and

receipt by the Company from the pharmaceutical alliance until the earlier of expiry of the Target Period or the last expiry date of the patents of royalties exceeding [**Redacted**] of Net Sales or a transfer price with a Gross Margin exceeding [**Redacted**] whilst

Net Sales shall mean Gross Revenues as defined in Exhibit 2.2, and

Gross Margin shall mean Net Sales less all costs of sales (including material, labour and overhead costs); and

the pharmaceutical alliance making an up-front payment to the Company that (net of costs for all activities related to or caused by the pharmaceutical alliance to the Alere-group including the Company) amounts to at least USD 1 million net (and as further set out in Target Table 3), and

the up-front payment is received within the Target Period.

The relevant amount of a Target Payment depends on the amount of the received up-front payment. The relevant figures are set out in the following Target Table 3. For each received upfront amount, just one “Cash Payment” (as referred to in the table) falls due being determined on the basis of the received upfront amounts from a pharmaceutical alliance, i.e. the “Cash Payment” amounts in the table are not to be summed up in case a received upfront amount equals or exceeds USD 2 million. The Parties explicitly acknowledge that a difference of USD 1 in relation to received upfront-payments can therefore cause a “Cash Payment” difference of up to USD 2.5 million, i.e. in case of an upfront payment received in the amount of USD 10 million the “Cash Payment” will be in total USD 5 million (rather than in total USD 2.5 million in case of an upfront payment received in an amount of USD 10 million less USD 1). If more than one upfront amount is received from the same pharmaceutical alliance within the relevant “Timeline”, such amounts are to be summed up and the respective total amount shall form the basis for determining the “Cash Payment”.

Target	Cash Payment	Timeline (as from Completion)
Validation of IP – Pharmaceutical alliances – [Redacted] and [Redacted]	Unlimited

Category 3 Payments (as defined in Exhibit 2.2) that are attributed to Gross Revenues due to the Sellers Representative exercising the Allocation Option (as defined in Exhibit 2.2) shall be disregarded in respect to Category 3 Targets, i.e. such Category 3 Payments will not be considered as royalties or up-front-payments in this Exhibit 2.4 but only as Gross Revenues in Exhibit 2.2. The amount of a Target Payment shall be calculated and agreed by the Parties immediately following expiration of the Target Period; the above Clause 3 shall apply to the payment terms.

Category 4: Validation of IP; Pharmaceutical Alliances; [**Redacted**] and [**Redacted**]

Category 4 Requirements are:

Creation of a pharmaceutical alliance (i.e. collaboration with other enterprises active in the pharmaceutical industry that are not being part of the Alere-group) under which the Company’s IP in the field of [**Redacted**] is validated, and

receipt by the Company from the pharmaceutical alliance as from Completion until the last expiry date of the patents of royalties exceeding [**Redacted**] of Net Sales or a transfer price with a Gross Margin exceeding [**Redacted**], and
