Upon the terms and subject to the conditions of this Agreement, at the Closing, the Sellers shall sell and transfer to Purchaser, and Purchaser shall purchase, the Sellers’ Shares and the Sellers’ Warrants, free and clear of all Encumbrances and with all rights attached and accruing to such Sellers’ Shares and Sellers’ Warrants at the Closing.

The Sellers, collectively represented by Nordic Capital, shall use best efforts to invoke their respective contractual right to acquire such Shares and Warrants, to procure that the Purchaser at the Closing Date may purchase the Shares and Warrants currently held by the Minority Holders from the relevant Sellers. For the avoidance of doubt, the Purchaser will be obligated to purchase the number of Shares and Warrants offered by the Sellers at the Closing Date on and subject to the terms of this Agreement.

The Sellers, collectively represented by Nordic Capital, undertake to keep the Purchaser informed on the number of Shares and Warrants that the Sellers have secured to be sold to the Purchaser at the Closing as well as of the response from the Minority Holders on a regular basis.

Subject to Purchaser having performed all obligations to be performed by it pursuant to Sections 4.2.2 and 7.3 (including but not limited to payment of the Purchase Price),

title of ownership to the Sellers’ Shares and Sellers’ Warrants shall transfer to the Purchaser at the Closing.

The purchase price for the Shares and Warrants shall be the Preliminary Purchase Price adjusted in accordance with Section 3.4.1 (the “Purchase Price”). The Purchase Price is calculated on a Fully Diluted Basis. For the avoidance of doubt, the Purchase Price assumes that 100 percent of the Shares and 100 percent of the Warrants are purchased and sold at the Closing. To the extent that less than 100 percent of the Shares and 100 percent of the Warrants are purchased and sold at the Closing, the Purchase Price shall be reduced proportionally as reflected in Exhibit B (as set forth in Section 3.1.2 below). The Purchase Price is also subject to further adjustment as contemplated by Section 3.4.

Following each relevant Seller’s acquisition of Shares and Warrants from the Minority Holders commencing before or after the date hereof, the Sellers shall procure that Nordic Capital, on behalf of the Sellers, prepares Exhibit B, so that it reflects the allocation of the Purchase Price at least two (2) but no more than five (5) Business Days prior to the Closing Date setting forth the number of Shares and Warrants to be sold by the Sellers to the Purchaser on the Closing Date. Such Exhibit B shall allocate the Purchase Price among the Sellers in proportion to their respective holdings of Shares or Warrants (as the case may be), whereby the purchase price for each Warrant shall be equal to the purchase price per Share, minus the relevant exercise price for such Warrant.

At the Closing, the Purchaser shall pay the Preliminary Purchase Price in NOK, less the Escrow Amount, and less any Warranty Escrow Amount (if applicable), by electronic transfer in immediately available funds to the Sellers, in the proportions set out in Exhibit B, to the accounts designated by the Sellers no later than five (5) Business Days prior to the Closing Date.

Further, Purchaser shall pay the Escrow Amount, at the Closing in NOK, by electronic transfer in immediately available funds to the Escrow Account.

Finally, if applicable pursuant to Section 9.4 hereof, Purchaser shall pay the Warranty Escrow Amount, at the Closing in NOK, by electronic transfer in immediately available funds to the Warranty Escrow Account.

As soon as reasonably practicable, but in no event later than sixty (60) days, after the Closing, the Parties shall jointly procure that the Company prepares, and delivers to Purchaser, in accordance with the Accounting Principles, a statement, in the form of the Benchmark Net Debt Statement and Benchmark Working Capital Statement, containing a calculation of the Net Debt and Working Capital as of the Closing Date (the “Closing Statement”). Purchaser shall, and shall cause its Affiliates to provide reasonable access on reasonable notice during normal business hours to Sellers to the books, accounting records and other documents (including supporting contractual documentation) and personnel of the Business reasonably required by Sellers for the purpose of agreeing or settling any dispute in relation to the Reviewed Closing Statement and allow Sellers to take copies of such documents at Sellers’ cost.

The Closing Statement shall be reviewed by the Business Auditors. Upon completion of the review, the Business Auditors shall render a report as set forth in Exhibit 9, which report shall be accompanied by a copy of the Closing Statement (the “Reviewed Closing Statement”). For the avoidance of doubt, amounts entered in the calculation of Net Debt shall not be entered in the calculation of the Working Capital. The Purchaser and the Sellers shall jointly procure that the Business Auditors deliver the Reviewed Closing Statement to Sellers and Purchaser no later than sixty (60) days after receipt of the Closing Statement. The fees and expenses of the Business Auditors in connection with the Reviewed Closing Statement shall be paid by the Sellers.

The Reviewed Closing Statement shall be delivered to the Purchaser and the Sellers, collectively represented by Nordic Capital, whom shall have the right to review the Reviewed Closing Statement.

The Purchaser and the Sellers, respectively, may dispute items under the Reviewed Closing Statement. The Purchaser and the Sellers, as the case may be, undertakes to notify the other Party of any such disputed items in writing within thirty (30) days from the receipt of the Reviewed Closing Statement. A notice under this Section 3.3.4 (an “Objection Notice”) shall be given in accordance with Section 11.7 and shall specify in reasonable detail the items in the Reviewed Closing Statement which are being disputed and a description in reasonable detail of the reasons for such dispute. If Sellers and Purchaser cannot agree on such items within fifteen (15) days after the notification, the disputed items shall be settled by the Disputes Auditors.

At the request of either Party, any dispute between the Parties relating to objections made to the Reviewed Closing Statement which cannot be resolved by them within fifteen (15) days after Sellers’ or the Purchaser’s, as the case may be, receipt of an Objection Notice shall be referred to the Disputes Auditor for decision in accordance with this Section 3.3.5 and Section 3.3.6.

The Disputes Auditors shall act as experts and not as arbitrators, shall review only the specific objections to the Reviewed Closing Statement as to which the Parties are in dispute as set out in the Objection Notice and shall make their determination based upon the terms, conditions and principles set forth in this Agreement and within the range of outcomes proposed by the Parties. The Parties agree that they will require the Disputes Auditors to render their decision within thirty (30) days after referral of the dispute to the Disputes Auditors for decision pursuant hereto. The decision of the Disputes Auditors shall be final and binding on the Sellers and the Purchaser.

All fees and expenses of the Disputes Auditors shall be borne by the Sellers and Purchaser equally.

The Reviewed Closing Statement shall become final and binding on Sellers and Purchaser upon the earliest to occur of: (i) if no Objection Notice has been given, the expiration of the period within which Purchaser or Sellers, as the case may be, may notify Sellers or Purchaser, as applicable, of any objections thereto pursuant to Section 3.3.4; (ii) the written agreement by Sellers and Purchaser that such Reviewed Closing Statement, together with any modifications thereto agreed by them, shall be final and binding; and; (iii) if a matter has been submitted to the Disputes Auditors in accordance with Section 3.3.6, three (3) days after the date on which the Disputes Auditors have issued their decision with respect thereto. The Reviewed Closing Statement, as adjusted, where applicable, pursuant to any agreement between the Parties or pursuant to the decision of the Disputes Auditors, when final and binding on both Parties in accordance with the immediately preceding sentence, is herein referred to as the “Final Closing Statement”.

Within five (5) Business Days after the Reviewed Closing Statement has become the Final Closing Statement pursuant to Section 3.3.8, the following adjustments shall be made:

(a) If the Benchmark Net Debt is greater than the Closing Net Debt, Purchaser shall pay to Sellers, in NOK and subject to Sections 3.4.1.2 and 3.4.2 hereof, by electronic transfer in immediately available funds, and to the account designated by Sellers in writing no later than three (3) Business Days prior to the date such payment is due, an amount equal to the difference between the Benchmark Net Debt and the Closing Net Debt.

(b) If the Benchmark Net Debt is lower than the Closing Net Debt, Sellers shall pay to Purchaser, in NOK and subject to Sections 3.4.1.2 and 3.4.2 hereof, by electronic transfer in immediately available funds, and to the account designated by the Purchaser in writing no later than three (3) Business Days prior to the date such payment is due, an amount equal to the difference between the Closing Net Debt and the Benchmark Net Debt.

The calculation of the Closing Net Debt shall be made according to the following principle:

In the event that the Purchaser so requests, the Company shall repay its debt to DnB NOR at the Closing Date. At the option and election of the Purchaser, such debt (including breakage-fees and interest) will either (a) be paid to DnB NOR by the Sellers, on behalf of the Company, out of the Preliminary Purchase Price received at the Closing Date, and such amount (including, for the avoidance of doubt, breakage costs, interest adjustments and accrued interest) paid by the Sellers to DnB NOR to fully satisfy any and all of the obligations of the Company to DnB NOR shall, for the purposes of reducing the Closing Net Debt, be excluded as a long-term liability in the calculation of the Closing Net Debt, or (b) be paid by the Purchaser on behalf of the Company, in which case all such amounts paid by the Purchaser to repay the debt, breakage costs, interest adjustments and accrued interest to DnB NOR (for the avoidance of doubt, excluding costs in relation to any new financing) shall be deemed to be outstanding Net Debt as of the Closing Date for determining the Closing Net Debt (and will not reduce the Closing Net Debt by virtue of the Purchaser’s payment of such amounts at the Closing Date).

(a) If the Closing Working Capital is less than the Benchmark Working Capital, Sellers shall pay to Purchaser, in NOK and subject to Section 3.4.2 hereof, by electronic transfer in immediately available funds, and to the account designated by the Purchaser in writing no later than three (3) Business Days prior to the date such payment is due, an amount equal to the difference between the Benchmark Working Capital and the Closing Working Capital.

(b) If the Closing Working Capital is greater than the Benchmark Working Capital, Purchaser shall pay to Sellers, in NOK and subject to Section 3.4.2 hereof, by electronic transfer in immediately available funds, and to the account designated by the Sellers in writing no later than three (3) Business Days prior to the date such payment is due, an amount equal to the difference between the Closing Working Capital and the Benchmark Working Capital.

Any proportionate reduction of the Purchase Price due to that less than 100 percent of the Shares and Warrants are sold and delivered at Closing pursuant to Section 3.1.1 shall be finally adjusted based on the final Purchase Price as adjusted in this Section 3.4.

(a) Any payments and/or repayments pursuant to Sections 3.4.1.1, 3.4.1.2 and 3.4.1.3 above shall be calculated so that only one (1) net payment shall be made between the Parties.

(b) Any repayments due to the Purchaser from the Sellers under this Section 3.4 shall primarily be made out of the Escrow Account. In case the Escrow Amount is less than the amount payable by the Sellers pursuant to this Section 3.4, an amount equal to the difference between the amount payable by the Sellers pursuant to this Section 3.4 and the Escrow Amount shall be paid by the Sellers in cash to a bank account designated by the Purchaser. In case a payment shall be made out of the Escrow Account, the Escrow Agent shall, in accordance with the Escrow Agreement, be instructed to immediately make such payment to an account designated by the Purchaser.

(c) Any payments due to the Sellers from the Purchaser under this Section 3.4 plus the amounts held in the Escrow Account, shall be paid in cash to one bank account as designated by the Sellers, collectively represented by Nordic Capital.

Any amount payable by either Party pursuant to this Section 3.4 shall be paid with interest thereon at a rate equal to the interest rate earned by the Escrow Account, calculated on the basis equal to the basis for calculation applicable to the Escrow Account, less any and all fees to the Escrow Agent, or if the Escrow Amount shall be partly paid to the Sellers and partly to the Purchaser, then such fees to the Escrow Agent shall be covered by the Parties in the same proportion as the Escrow Amount becomes payable to them.

That the Parties’ respective representations, warranties, covenants and other obligations as set forth in this Agreement in all material aspects remain true, accurate, validly performed and complied with, as though such representations and warranties were made again by the Parties at the Closing, and that this has been confirmed by the respective Parties pursuant to Section 4.2 hereof, provided, however, that in the event of any circumstance or circumstances occurring prior to the Closing involving a claim or claims, as the case may be, by the Purchaser of breaches of the Sellers’ Warranties or Title or Capacity Warranties contained herein, the following shall apply:

(i) In the event the claims by the Purchaser involve breach of Warranties that may reasonably be expected to result, when aggregated, in claims for breach of Warranties having an aggregate value less than the Substantiated Claims Amount (taking into account possible limitations on the value of claims set forth in Sections 9.4 and 9.5 hereof), the Parties shall nonetheless be required to proceed with the Closing and the procedure set forth in Section 9.4 hereof shall apply to address such claims.

(ii) In the event the claims by the Purchaser involve breach of Title or Capacity Warranties, or involve breach of Warranties that may reasonably be expected to result, when aggregated, in a claim or claims, as the case may be, for breach of Warranties having an

aggregate value in excess of the Substantiated Claims Amount (taking into account possible limitations on the value of claims set forth in Sections 9.4 and 9.5 hereof), the Purchaser shall not be required to proceed with the Closing unless it otherwise agrees to proceed with the Closing. For the avoidance of any doubt, should the Purchaser decide to proceed with the Closing, irrespective of the fact that the Purchaser is not obligated to do so pursuant to this Section 8.1(c)(ii), the Purchaser shall not be entitled to, prior to or after the Closing Date, bring a claim against the Sellers for such asserted breach of the Warranties or Title and Capacity Warranties and, unless otherwise specifically agreed to in writing by the Parties prior to the Closing, shall further not be entitled to any remedy of any kind with respect to such asserted breach of the Warranties or Title and Capacity Warranties.

Receipt of all necessary third party consent to the Material Contracts listed in paragraphs 11, 17, 18, 23 and 25 of Exhibit 10.

PURCHASER’S REMEDIES AND SELLERS’ LIMITATIONS ON LIABILITY AND NO-RECOURSE

Each of the warranties set out in Sections 5.1 and 5.2 (the “Title and Capacity Warranties”) shall survive Closing and the Purchaser shall be entitled to, at any time after the Closing Date, bring a claim against the Sellers for breach of the Title and Capacity Warranties. The maximum respective liability of each Seller for any breach of the Title and Capacity Warranties shall be limited to the total amount of consideration received by the respective Seller pursuant to this Agreement.

For the avoidance of doubt, in the absence of fraud, deliberate non-disclosure or wilful concealment, all liability of the Sellers under this Agreement (other than in respect of the Title and Capacity Warranties) will lapse, except for the post-closing adjustment set forth in Section 3.4 and subject to Section 9.4.3 hereof, on and after the Closing Date. In case of breach of Warranties involving fraud, deliberate non-disclosure or wilful concealment by Sellers, the Purchaser has a right to seek monetary relief in the form of adjustment of the Purchase Price provided, however, that the Purchaser shall not be able to claim that any fact, circumstances or matter gives rise to a claim if such fact, circumstances or matter and the consequence that such fact, circumstances or matter constitutes a breach of Warranties constitutes Purchaser’s Knowledge as per the Closing Date. For the avoidance of doubt, if the Sellers allege that any fact, circumstance or matter, and the consequence that such fact, circumstance or matter constitutes a breach of Warranties, was within the scope of the Purchaser’s Knowledge as of the Closing Date, the Sellers shall bear the burden of proof with respect thereto.

The obligations of the Sellers’ under this Agreement shall be several and not joint obligations.

In the event of any circumstances occurring prior to Closing which may reasonably be expected, by the Purchaser, to result in a claim or claims for breaches of Warranties that do not, in aggregate, result in a claim or claims equal to or in excess of the Substantiated Claims Amount as set forth in Section 8.1(c) of the Agreement, provided, however, that each such claim is individually in excess of NOK 250,000, the following shall apply:

9.4.1 If prior to the Closing Date the Purchaser becomes aware of relevant facts or circumstances giving rise to a claim for breach of Warranties, the Purchaser shall give notice in writing to the Sellers (collectively represented by Nordic Capital) within five (5) days from the date when the Purchaser became aware of the relevant facts or circumstances giving rise to the claim for breach of Warranties and the consequence that such facts constituted a breach of Warranties. Such notice shall be accompanied with reasonable particulars of the potential claim.

9.4.2 If prior to the Closing, the Purchaser has provided notice to the Sellers, pursuant to Section 9.4.1 above, regarding claims that are not reasonably likely to meet or exceed the Substantiated Claims Amount (taking into account possible limitations on the value of claims set forth in Section 9.5 hereof and subject to the limitation set forth in the first paragraph of this Section 9.4), then the Parties shall be obligated to proceed with the Closing despite such potential claims and the Purchaser shall be entitled to a reduction in the Purchase Price for the value of such claims as, subject to Section 9.4.3 below, mutually agreed to by the Purchaser and the Sellers (collectively represented by Nordic Capital).

9.4.3 In the event the Parties are unable to agree on the amount of the reduction in the Purchase Price to address such claims, the Parties nonetheless shall be obligated to proceed with the Closing, reducing the Purchase Price by any mutually agreed amount for the noticed claims, and an amount equal to the disputed value of the noticed claims made by the Purchaser (the “Warranty Escrow Amount”) shall be placed on an escrow account (the “Warranty Escrow Account”) with the Warranty Escrow Agent until the dispute between the parties has been finally settled pursuant to Section 11.9 hereof. Further, the Purchaser and the Sellers, collectively represented by Nordic Capital, shall, on the Closing Date, execute and deliver, and shall cause the Warranty Escrow Agent to execute and deliver, an escrow agreement (the “Warranty Escrow Agreement”) substantially in the form set out in Exhibit 14. For the avoidance of doubt, any monetary relief to the Purchaser following final settlement of such disputed claims shall be limited to the Warranty Escrow Amount and be paid out of the Warranty Escrow Account.

9.4.4 For the avoidance of doubt, if prior to the Closing, the Purchaser has provided notice to the Sellers regarding claims that are reasonably likely to meet or exceed the Substantiated Claims Amount (taking into account possible limitations on the value of claims set forth in Section 9.5 hereof), then the Purchaser shall not be obligated to proceed with the Closing unless the Purchaser otherwise agrees to proceed with the Closing, in which case the provisions in Section 8.1(c)(ii) hereof shall apply.

Notwithstanding anything in this Agreement to the contrary, the provisions of this Section 9.5 shall operate to limit the ability of the Purchaser to assert what could otherwise be a claim that might qualify toward the Substantiated Claims Amount in respect of any breach of or any inaccuracy in the Warranties.

9.5.1 Allowance, provision or reserve in the Accounts or the Management Accounts

No matter shall be the subject of a claim for breach of a Warranty counting towards the Substantiated Claim Amount to the extent that a specific allowance, provision or reserve in respect of such matter, and in an amount sufficient to cover such potential claim, shall have been made in the Financial Statements. Should a specific allowance, provision or reserve in respect of such matter made in the Financial Statements only cover part of such potential claim, the part of such potential claim so covered in the Financial Statements shall be disregarded when counting towards the Substantiated Claim Amount.

9.5.2 Limitations on amount of claim to qualify towards the Substantiated Claims Amount

The value of any claim for breach of Warranties asserted by the Purchaser for purposes of qualifying toward the Substantiated Claims Amount shall be reduced by any amounts actually received by the Purchaser (or actually received by the Acquired Companies which will become the property of the Purchaser following the Closing), regardless of whether such amounts are received prior to or following Closing, under any policy of insurance or from any third party in respect of such claim or otherwise made good for without cost to the Purchaser or the Acquired Companies, provided, however, that any amounts received by any of the Acquired Companies that are used pursuant to this Section 9.5.2 to reduce the value of a potential claim for breach of Warranties shall be excluded from the calculation of the (i) Net Debt as of the Closing Date, and not counted as cash held by the Acquired Companies for purposes of calculating the Closing Net Debt or (ii) Working Capital as of the Closing Date, and not counted as another asset held by the Acquired Companies for purposes of calculating the Closing Working Capital.

No claim for breach of Warranties can be asserted toward the Substantiated Claims Amount by the Purchaser where such claim is wholly attributable to any voluntary act, omission, transaction or arrangement specifically requested by the Purchaser or otherwise

specifically consented to in writing by the Purchaser prior to the occurrence of such voluntary act, omission, transaction or arrangement.

No claim for breach of Warranties can be asserted toward the Substantiated Claim Amount by the Purchaser if the facts specifically giving rise to the relevant claim and the consequence that such facts constituted a breach of Warranty was within the scope of Purchaser’s Knowledge as of the date of this Agreement. For the avoidance of doubt, if any claim by the Purchaser for breach of Warranties is alleged by the Sellers to have been within the scope of Purchaser’s Knowledge as of the date of this Agreement, the Sellers shall have the burden of proof to show that the facts specifically giving rise to the relevant claim and the consequence that such facts constituted a breach of Warranty was within the scope of Purchaser’s Knowledge as of the date of this Agreement.

Other than in respect of breach of the Title and Capacity Warranties and breach of Warranties based on fraud, deliberate non-disclosure or wilful concealment by Sellers, Purchaser has no other recourse for a breach of Warranties other than to make a claim or claims towards the Substantiated Claim Amount as set forth in Section 8.1(c)(i) of the Agreement.

Each Party hereto acknowledges and agrees that its sole and exclusive remedy with respect to any and all claims relating to the subject matter of this Agreement shall be pursuant to the provisions set forth in this Agreement and hereby waives, to the fullest extent permitted under applicable law, any and all other remedies (including but not limited to any right to terminate this Agreement) it would otherwise have against the other Party in connection with the transactions contemplated hereby.

For the avoidance of doubt, the limitations in this Article 9 shall apply instead of any provisions limiting a purchaser’s right to make a claim for breach of representation or warranty according to the Swedish Sale of Goods Act of 1990 or other applicable non-mandatory legislation.

Either of the Purchaser and the Sellers has the right to terminate the Agreement if any of the Conditions to Closing in Section 8.1 are not fulfilled within 180 days from the date hereof.

If this Agreement is terminated and the transactions contemplated hereby are abandoned as described herein, this Agreement shall become null and void and of no further force and effect, except for the provisions of this Agreement relating to expenses (including but not limited to Section 11.10), this Section 10.1, and Articles 9 and 11. Nothing in this Section 10.1 shall be deemed to release either of the Parties from any liability for any breach by such Party of the terms and provisions of this Agreement prior to termination.

If this Agreement is terminated and the transactions contemplated hereby are abandoned as described in this Section 10.1, the Parties shall promptly return to the other Party or certify the destruction of (i) all documents and other material received from the other Party and/or its Affiliates relating to such transactions, whether so obtained before or after the execution hereof; and (ii) all written information received from the other Party with respect to the Business and/or the other operations of either Party and/or its Affiliates (in each case together with all copies thereof).

This Agreement may not be amended except by an instrument in writing signed on behalf of each of the Parties hereto by their duly authorized representatives.

No delay or failure on the part of any Party to exercise any right, power or remedy in respect of this Agreement shall constitute a waiver thereof (other than a failure to provide a notice or take any action which is subject to a time limit as specified in this Agreement).

Except as may be required by law or by obligations pursuant to any listing agreement with Nasdaq, the Stockholm Stock Exchange or any other applicable national securities or recognized investment exchange, Purchaser and Sellers (from and after the Closing Date) shall consult with each other before issuing any press release, announcement, communications, circular with respect to this Agreement and shall not issue any such press release, announcement, communication, circular or make any such public statement without the prior consent of the other party, which shall not be unreasonably withheld, delayed or conditioned.

(a) Neither Party hereto shall, and each Party hereto shall ensure that none of its Affiliates will, disclose any information of a confidential nature relating to the Business or Purchaser (in the case of Sellers) or to Sellers (in the case of Purchaser) to any third Person. The obligation of either Party under this Section 11.1.2 shall not apply to any of the following: (i) disclosure of such confidential information required by applicable law or applicable stock exchange rules; (ii) disclosure of such confidential information to such Party’s professional advisors who have been made aware of the confidential nature of such information; (iii) disclosure of such confidential information for the purpose of defending any claim against the other Party under this Agreement or enforcing its rights hereunder; or (iv) disclosure of such confidential information which is or comes into the public domain other than as a result of the breach by such Party of this Section 11.1.2.

(b) Sellers shall have the right to retain copies of all documents delivered or made available to Purchaser in connection with the transactions contemplated hereby to be used solely for the purpose of defending any claim against Sellers under this Agreement. Such copies of documents shall be retained in escrow by White & Case Advokat AB, subject to escrow instructions reasonably acceptable to the Parties.

Unless otherwise expressly provided in this Agreement, whenever the Parties are required to cooperate for any particular purpose hereunder, neither Party, nor their respective Affiliates, shall be required to make any material monetary expenditure, commence or be a plaintiff in any litigation or offer or grant any material accommodation or concession (financial or otherwise) to any Person.

This Agreement supersedes any and all other agreements, oral or written, between the Parties hereto with respect to the subject matter hereof, and contains the entire agreement between such Parties with respect to the transactions contemplated hereby.

Should any of the provisions of this Agreement be or become invalid or unenforceable, in whole or in part, the other provisions of this Agreement shall remain in force. The Parties shall replace the invalid or unenforceable provisions, according to the intent and purpose of this Agreement, with such valid provisions which in their economic effect come as close as legally possible to that of the invalid or unenforceable provisions.

This Agreement shall be directed and interpreted to the advantage of the Parties only and their permitted assignees, and no third Person shall obtain any rights by virtue hereof.

Neither Party may assign its rights or obligations under this Agreement to any third Person without the prior written consent of the other Parties, except that Purchaser may, at its election, assign any and all of its rights, interests or obligations under this Agreement to a direct or indirect wholly owned subsidiary of Purchaser, provided that the Purchaser will remain fully liable under this Agreement for the assignee as for its own debt and the Purchaser shall not be relieved of any of its obligations hereunder in case of such assignment.

All notices and other communications that are required or permitted to be given under this Agreement shall be in writing, in the English language and hand delivered or sent by registered mail (return receipt requested) or confirmed facsimile to the following addresses (which may be changed in writing by notice to the appropriate address):

This Agreement shall be governed by, and construed in accordance with, the substantive laws of Sweden (without regard to its principles of conflict of laws).

The Parties will use their best efforts to resolve amicably any dispute, controversy or claim arising out of or in connection with this Agreement, or the breach, termination or invalidity thereof.

Any dispute, controversy or claim arising out of or in connection with this Agreement, or the breach, termination or invalidity thereof, which cannot be settled amicably within thirty (30) days of written notice by either Party describing in reasonable detail the dispute, controversy or claim, shall be finally settled by arbitration in accordance with the Rules of the Arbitration Institute of the Stockholm Chamber of Commerce.

The arbitral tribunal shall be composed of three (3) arbitrators. Where there are multiple parties on either side, the Arbitration Institute shall appoint all three (3) arbitrators.

The place of arbitration shall be Stockholm, Sweden. The language to be used in the arbitration proceedings, whether written or oral, shall be English.

The Parties undertake and agree that all arbitral proceedings conducted with reference to this arbitration clause will be kept strictly confidential and that this confidentiality undertaking shall cover all information disclosed in the course of such arbitral proceedings, as well as any decision or award that is made or declared during the proceedings. Information covered by this confidentiality undertaking may not, in any form, be disclosed by either Party to a third party without the prior written consent of the other Party. Notwithstanding what is now stated, a party shall not be prevented from disclosing such information as required in connection

with an appeal of the arbitral decision or award or if such disclosure is required by statute, regulation or a decision by a governmental authority in which case the disclosing Party shall give as much advance notice as is practicable to the other Party in order to allow the other Party the opportunity of seeking to limit such disclosure through appropriate means.

Unless otherwise expressly provided in this Agreement, all costs and expenses incurred in connection with the preparation, negotiation and implementation of this Agreement and the transactions contemplated hereby shall be borne by the Party incurring such costs and expenses. Any and all costs to White & Case, Thommessen Krefting Greve Lund AS Advokatfirma and PricewaterhouseCoopers AS (and Advokatfirmaet PricewaterhouseCoopers DA) for services rendered in connection with this Agreement and the transactions contemplated hereby shall be borne by the Sellers.

After the Closing Date, the Parties shall execute such other documents or take, or cause to be taken, such other actions to the extent they have not been accomplished on the Closing Date, as may be required to transfer the Shares and Warrants to the Purchaser in accordance with this Agreement.

Each of the Parties hereto has caused this Agreement to be executed by its duly authorized representatives on the date first set forth above. This Agreement has been executed in four (4) original copies of which each Party has taken one.

This agreement is made as of [date] 2005 (the “Escrow Agreement”), by and among [DnB NOR] (“Escrow Agent”), Invitrogen Corporation (the “Purchaser”), and the selling shareholders (the “Sellers”) of Dynal Biotech Holding AS (the “Company”) as represented by Nordic Capital IV Limited (the “Seller Representative”). Terms not otherwise defined herein shall have the same meaning as set forth in the SPA (as defined below).

WHEREAS, the Purchaser and the Sellers have entered into a Share Sale and Purchase Agreement dated as of February 7, 2005 (the “SPA”), providing for the purchase of all the shares and warrants of the Company by the Purchaser;

WHEREAS, pursuant to Section 1.1 of the SPA, a copy of which is attached hereto as Annex A, the Escrow Amount shall be deposited on the Escrow Account, which Escrow Account will be established to compensate the Purchaser, if applicable and in accordance with the terms and conditions of the SPA, for any payment obligation of the Sellers pursuant to Section 3.4 of the SPA with respect to adjustments stipulated in the Final Closing Statement;

WHEREAS, the Seller Representative has been constituted as agent for and on behalf of the Sellers to undertake certain obligations;

WHEREAS, Section 1.1 of the SPA provides for an Escrow Account to be held by the Escrow Agent; and

WHEREAS, the parties hereto desire to set forth further terms and conditions in addition to those set forth in the SPA relating to the operation of the Escrow Account.

NOW, THEREFORE, in consideration of the mutual covenants contained herein and subject to the terms and conditions set forth herein, the parties hereby agree as follows:

Pursuant to the SPA, the Purchaser shall deposit in escrow with the Escrow Agent, as escrow agent, the Escrow Amount, which deposit will constitute the Escrow Account. The Escrow Amount standing on the Escrow Account shall be held and distributed by the Escrow Agent in accordance with this Escrow Agreement. The Escrow Agent has opened the Escrow Account (account # [account number]) in the joint names of the Purchaser and the Seller Representative.

The Escrow Agent shall be entitled to such rights and shall perform such duties of the Escrow Agent as set forth herein (collectively, the “Duties”), in accordance with the terms and conditions of this Escrow Agreement. As among themselves, the Purchaser and the Seller Representative shall be entitled to their respective rights and shall perform their respective duties and obligations as set forth herein. In the event that the terms of this Escrow Agreement conflict in any way with the provisions of Section 1.1 or Section 3.4.2 of the SPA, respectively, Section 1.1 and Section 3.4.2 of the SPA shall prevail.

The period of time during which the Escrow Account shall be in existence (the “Escrow Period”) shall commence immediately following the Closing Date, and shall terminate on the date when either (i) payments pursuant to Section 3.4.2 of the SPA have been made by the Sellers satisfying in full the Sellers’ payment obligation pursuant to Section 3.4.2 of the SPA, (ii) it has been finally established, pursuant to the Final Closing Statement, that the Sellers have no further payment obligation whatsoever to the Purchaser pursuant to Section 3.4 of the SPA, (iii) the Escrow Agent receives a joint written instruction signed by each of the Purchaser and the Seller Representative with specific instructions to the Escrow Agent with respect to the distribution of all or part of the Escrow Amount, or (iv) an award from an arbitration tribunal pursuant to the SPA entitling the Sellers, as specified in such award, to obtain the release from the Escrow Account of all or part of the Escrow Amount.

a. The Escrow Agent shall be obligated only for the performance of the Duties as are specifically set forth herein. The Escrow Agent shall neither be responsible for, nor chargeable with knowledge of, the terms and conditions of any other agreement, instrument or document executed between/among the parties hereto, except as may be specifically provided in Annex A hereto. This Escrow Agreement sets forth all of the obligations of the Escrow Agent, and no additional obligations shall be implied from the terms of this Escrow Agreement or any other agreement, instrument or document. The Escrow Agent may conclusively rely and shall be protected in relying or refraining from acting on any instrument reasonably believed to be genuine and to have been signed or presented by the proper party or parties. The Escrow Agent shall not be liable for any act done or omitted hereunder as Escrow Agent while acting in good faith and in the absence of gross negligence or willful misconduct.

b. The Escrow Agent is hereby expressly authorized to comply with and obey final orders, judgments or decrees of any court of law or binding resolution of arbitration, notwithstanding any notices, warnings or other communications from any party or any other person to the contrary. In case the Escrow Agent obeys or complies with any such order, judgment or decree of any court or binding resolution of arbitration, the Escrow Agent shall not be liable to any of the parties hereto or to any other person by reason of such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction.

c. The Escrow Agent shall not be liable in any respect on account of the identity, authority or rights of the parties executing or delivering or purporting to execute or deliver this Escrow Agreement or any documents or papers deposited or called for hereunder. The Escrow Agent shall not be responsible for the genuineness, validity, enforceability or sufficiency of title to any cash or other property delivered to it hereunder.

d. In performing its Duties under or in connection with this Escrow Agreement, the Escrow Agent shall not be liable to any party for damages, losses, or expenses, except as a result of gross negligence or willful misconduct on the part of the Escrow Agent. In no event shall the Escrow Agent be liable for special, consequential or indirect damages.

e. If any controversy arises between the parties to this Escrow Agreement, or with any other party, concerning the subject matter of this Escrow Agreement, its terms and conditions, the Escrow Agent will not be required to determine the controversy or to take any action regarding it. The Escrow Agent may wait for settlement of any such controversy by final appropriate legal proceedings or other means as, in the Escrow Agent’s discretion, the Escrow Agent may require, despite what may be set forth elsewhere in this Escrow Agreement. In such event, the Escrow

Agent will not be liable for damage, except if resulting from the gross negligence or willful misconduct on the part of the Escrow Agent.

f. The Purchaser and the Sellers and their respective successors and assigns agree jointly and severally to indemnify and hold Escrow Agent harmless against any and all losses, claims, damages, liabilities, and expenses, including reasonable costs of investigation, counsel fees, and disbursements (Losses) that may be imposed on Escrow Agent or incurred by Escrow Agent in connection with the performance of the Duties, except for Losses that result from gross negligence or willful misconduct on the part of the Escrow Agent. The provisions of this section 5(f) shall survive the termination of this Escrow Agreement or the resignation or removal of the Escrow Agent.

g. The Purchaser and the Sellers and their respective successors and assigns agree jointly and severally to indemnify and hold the Escrow Agent harmless from and against any taxes, additions for late payment, interest, penalties and other expenses, that may be assessed against the Escrow Agent on any such payment or other activities under this Escrow Agreement.

The Seller Representative undertakes to assume responsibility for governmental reporting associated with the withholding, other taxes, assessments, other governmental charges or certifications under this Escrow Agreement. The Purchaser and the Sellers and their respective successors and assigns agree jointly and severally to indemnify and hold the Escrow Agent harmless from any liability on account of taxes, assessments or other governmental charges, including without limitation the withholding or deduction or the failure to withhold or deduct the same, and any liability for failure to obtain proper certifications or to properly report to governmental authorities, to which the Escrow Agent may be or become subject in connection with or which arises out of this Escrow Agreement, including costs and expenses (including reasonable legal fees), interest and penalties.

h. Any actions or direction of the Sellers delivered to the Escrow Agent pursuant to any provision of this Escrow Agreement shall be executed by the Seller Representative.

i. The Escrow Agent shall be under no duty to give the property held in escrow by it hereunder any greater degree of care than it gives its own similar property.

The Escrow Agent’s Duties may be altered, amended, modified or revoked only by a written instrument signed by all the parties hereto.

The Escrow Agent may resign at any time upon giving at least thirty (30) days’ written notice to the other parties; provided, however, that no such resignation shall become effective until the appointment of a successor escrow agent which shall be accomplished as follows: the parties shall use their best efforts to mutually agree on a successor escrow agent within thirty (30) days after receiving such notice. If the parties fail to agree upon a successor escrow agent within such time, the Escrow Agent shall have the right to appoint a reputable successor escrow agent authorized to do business in Norway that is engaged in the business of providing escrow

services. The successor escrow agent shall execute and deliver an instrument accepting such appointment and it shall, without further acts, be vested with all the estates, properties, rights, powers, and duties of the predecessor escrow agent as if originally named as escrow agent. The Escrow Agent shall upon appointment of such successor escrow agent be discharged from any further duties and liability under this Escrow Agreement.

If the Escrow Agent reasonably requires other or further instruments in connection with performance of its Duties, the necessary parties hereto shall join in furnishing such instruments.

An upfront fee of NOK [ ] and reasonable out-of-pocket costs of the Escrow Agent for performance of its Duties shall primarily be paid out of interest earned on the Escrow Account or, if and to the extent insufficient, by the [Purchaser/Purchaser and Sellers jointly].

a. Any notice permitted or required hereunder shall be in writing and shall be deemed to have been given if delivered personally or if by mail certified or registered mail, postage prepaid, or sent via facsimile (with acknowledgement of complete transmission) to the parties at their address set forth below or to such other address as they may hereafter designate:

or to such other address as any party may have furnished in writing to the other parties in the manner provided above.

b. Neither the Purchaser nor the Seller Representative nor the Escrow Agent shall be responsible for delays or failures in performance resulting from acts beyond its control. Such acts shall include but not be limited to acts of God, strikes, lockouts, riots, acts of war, epidemics, governmental regulations superimposed after the fact, fire, communication line failures, computer viruses, power failures, earthquakes or other disasters.

c. The captions in this Escrow Agreement are for convenience only and shall not be considered a part of or affect the construction or interpretation of any provisions of this Escrow Agreement.

d. This Escrow Agreement may be executed in any number of counterparts, each of which when so executed shall constitute an original copy hereof, but all of which together shall constitute one agreement.

e. No party may, without the prior express written consent of each other party, assign this Escrow Agreement in whole or in part to any third party. This Escrow Agreement shall be binding upon the respective parties hereto and their heirs, executors, successors and assigns.

f. This Escrow Agreement may not be altered or modified except in writing, nor shall the conduct of the parties constitute a waiver of any of the terms and conditions of this Escrow Agreement, unless such waiver is specified in writing, and then only to the extent so specified. A waiver of any of the terms and conditions of this Escrow Agreement on one occasion shall not constitute a waiver of the other terms of this Escrow Agreement, or of such terms and conditions on any other occasion.

h. This Escrow Agreement shall be governed by and construed in accordance with [the laws of the Kingdom of Sweden].

IN WITNESS WHEREOF, each of the parties has executed this Escrow Agreement as of the date first above written.
