The exercise price per share of such Converted Stock Option shall be adjusted so that it is equal to (x) the exercise price per share of such Janus Option immediately prior to the Effective Time divided by (y) the Exchange Ratio, rounded up to the nearest cent; provided , however that the exercise price and the number of Henderson Ordinary Shares purchasable pursuant to a Converted Stock Option shall be subject to such adjustments as may be necessary for the foregoing conversion to satisfy the requirements of Sections 409A, 422 and 424 of the US Internal Revenue Code of 1986, as amended (the Code ) and Treasury Regulations Section 1.424-1.

8

Award immediately prior to the Effective Time by the (B) Exchange Ratio.

(b)                                  Exchange Procedures.

shares in accordance with Section 3.2(e)  and any dividends or other distributions on Henderson Ordinary Shares in accordance with Section 3.2(c) .  Upon surrender of a Certificate (or affidavit of loss in lieu thereof) or Book-Entry Share, as applicable, for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Henderson, together with such letter of transmittal, duly executed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate or Book-Entry Share shall be entitled to receive in exchange therefor the Merger Consideration (which shall include cash in lieu of fractional shares as provided in Section 3.2(e) ) that such holder has the right to receive pursuant to the provisions of this ARTICLE III and any amounts that such holder has the right to receive in respect of dividends or other distributions on Henderson Ordinary Shares in accordance with Section 3.2(c) .  Henderson shall instruct the Exchange Agent to mail such amounts to such holders within three (3) Business Days following the Exchange Agent’s receipt of such Certificate (or affidavit of loss in lieu thereof) or Book-Entry Share, and the Certificate or Book-Entry Share so surrendered shall forthwith be cancelled.  If any portion of the Merger Consideration is to be registered in the name of or, if applicable, paid to a person other than the person in whose name the applicable surrendered Certificate or Book-Entry Share is registered, it shall be a condition to the registration and, if applicable, payment of such Merger Consideration that the surrendered Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such delivery of the Merger Consideration shall pay to the Exchange Agent any transfer or other Taxes required by reason of such registration in the name of a person other than the registered holder of such Certificate or Book-Entry Share or establish to the reasonable satisfaction of the Exchange Agent that such Tax has been paid or is not applicable.

(ii)                                   Until surrendered as contemplated by this Section 3.2 , each Certificate or Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration and any amounts that such holder has the right to receive in respect of dividends or other distributions on Henderson Ordinary Shares in accordance with Section 3.2(c) .  No interest shall be paid or shall accrue for the benefit of holders of Certificates or Book-Entry Shares on the Merger Consideration payable upon the surrender of Certificates or Book-Entry Shares.

(d)                                  No Further Ownership Rights in Janus Common Stock.   All Henderson Ordinary Shares issued upon the surrender for exchange of Certificates or Book-Entry Shares in accordance with the terms of this ARTICLE III shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the shares of Janus Common Stock, theretofore represented by such Certificates or Book-Entry Shares, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Janus Common Stock that were outstanding immediately prior to the Effective Time.  If, after the Effective Time, Certificates or Book-Entry Shares are presented to Henderson or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this ARTICLE III , except as otherwise provided by Applicable Law.

(e)                                   Fractional Shares.

(i)                    No certificates or scrip representing fractional Henderson Ordinary Shares shall be issued upon the surrender for exchange of Certificates or Book-Entry Shares, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a holder of Henderson Ordinary Shares.

(ii)            Notwithstanding any other provision of this Agreement, each holder of shares of Janus Common Stock converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of Henderson Ordinary Shares (after aggregating all Certificates and Book-Entry Shares delivered by such holder) shall receive, in lieu thereof, cash (in a US dollar amount), without interest, in an amount equal to such fraction as determined below.  As promptly as practicable following the Effective Time, the Exchange Agent shall determine the excess of (i) the number of full Henderson Ordinary Shares delivered to the Exchange Agent by Henderson for issuance to holders of Certificates or Book-Entry Shares over (ii) the aggregate number of full Henderson Ordinary Shares to be distributed to holders of Certificates or Book-Entry Shares (such excess being herein referred to as the Excess Shares ).  As soon as practicable

after the Effective Time, the Exchange Agent, as agent for such holders of Certificates or Book-Entry Shares, shall sell the Excess Shares at then prevailing prices on the Exchange, all in the manner provided herein.

(iii)           The sale of the Excess Shares by the Exchange Agent shall be executed on the Exchange and shall be executed in round lots to the extent practicable.  Until the net proceeds of any such sale or sales have been distributed to the holders of Certificates or Book-Entry Shares, the Exchange Agent shall hold such proceeds in trust for such holders.  The net proceeds of any such sale or sales of Excess Shares to be distributed to the holders of Certificates or Book-Entry Shares shall be reduced by any and all brokerage commissions, transfer Taxes and other out-of-pocket transaction costs of the Exchange Agent incurred in connection with such sale or sales.  The Exchange Agent shall determine the portion of such net proceeds to which each holder of Certificates or Book-Entry Shares shall be entitled, if any, by multiplying (A) the amount of the aggregate net proceeds by (B) a fraction (1) the numerator of which is the amount of the fractional share interest to which such holder of Certificates or Book-Entry Shares is entitled (after taking into account all Certificates and Book-Entry Shares then held by such holder) and (2) the denominator of which is the aggregate amount of fractional share interests to which all holders of Certificates or Book-Entry Shares are entitled.  As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of Certificates or Book-Entry Shares with respect to any fractional share interests, the Exchange Agent shall promptly pay such amounts to such holders subject to and in accordance with this Section 3.2(e) .

(iv)           Notwithstanding the provisions of this Section 3.2(e) , Henderson may elect, at its option exercised prior to the Effective Time, to pay to the Exchange Agent an amount in cash in US dollars, to be deposited on the first Business Day following the Effective Time, sufficient for the Exchange Agent to pay each holder of Certificates or Book-Entry Shares an amount in cash equal to the product obtained by multiplying (A) the fraction of a Henderson Ordinary Share to which such holder would otherwise have been entitled by (B) the closing price for a Henderson Ordinary Share on the Exchange on the first Business Day immediately following the Effective Time. In such event, all references in this Agreement to the net proceeds from the sale of the Excess Shares and similar references shall be deemed to refer to the payments calculated in the manner set forth in this Section 3.2(e)(iv) .

(f)                                    Return of Merger Consideration.   Any portion of the Merger Consideration made available to the Exchange Agent pursuant to Section 3.2(a)  or any dividends or other distributions on Henderson Ordinary Shares in accordance with Section 3.2(c)  that remains undistributed to the holders of the Certificates or Book-Entry Shares for one year after the Effective Time shall be delivered to Henderson, upon demand, and any holders of the Certificates or Book-Entry Shares who have not

14

theretofore complied with this ARTICLE III shall thereafter be entitled to look only to Henderson for payment of their claim for any Henderson Ordinary Shares, any cash in lieu of fractional Henderson Ordinary Shares and any dividends or distributions with respect to Henderson Ordinary Shares.

(g)                                   No Liability.   None of Janus, Henderson, Merger Sub, the Surviving Corporation or the Exchange Agent shall be liable to any person in respect of any portion of the Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.  If any Certificate (or affidavit of loss in lieu thereof) or Book-Entry Share has not been surrendered prior to seven years after the Effective Time, or immediately prior to such earlier date on which any Henderson Ordinary Shares, any cash in lieu of fractional Henderson Ordinary Shares or any dividends or distributions with respect to Henderson Ordinary Shares in respect of such Certificate or Book-Entry Share would otherwise escheat to or become the property of any Governmental Entity (as defined herein), any such shares, cash, dividends or distributions in respect of such Certificate or Book-Entry Share shall, to the extent permitted by Applicable Law, become the property of Henderson, free and clear of all claims or interests of any person previously entitled thereto.

(h)                                  Withholding Rights.   Each of Henderson, the Surviving Corporation and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign Tax law.  To the extent that amounts are so withheld or paid over to or deposited with the relevant Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the person in respect of which such deduction and withholding was made.

(i)                                      Lost Certificates.   If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed, the Exchange Agent shall deliver in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration with respect to the shares of Janus Common Stock formerly represented thereby, any cash in lieu of fractional Henderson Ordinary Shares, and unpaid dividends and distributions on Henderson Ordinary Shares deliverable in respect thereof, pursuant to this Agreement.

15(f) of the Investment Company Act not to be met in respect of the Transactions, and shall not fail to take, and, after the Closing, shall cause its Affiliates not to fail to take, any action if the failure to take such action would have the effect, directly or indirectly, of causing the requirements of any of the provisions of Section 15(f) of the Investment Company Act not to be met in respect of the Transactions.  In that regard, Henderson shall conduct its business and shall cause each of its affiliates to conduct its business so as to assure that:

(A)                                for a period of not less than three years after the Closing, at least 75% of the members of the boards of trustees of each Janus Public Fund are not (I) “interested persons” (within the meaning of Section 2(a)(19) of the Investment Company Act) of the investment adviser of such Janus Public Fund after the Closing or (II) “interested persons” (within the meaning of Section 2(a)(19) of the Investment Company Act) of the investment adviser of such Janus Public Fund immediately prior to the Closing; and

(B)                                for a period of not less than two years after the Closing, there shall not be imposed on any Janus Public Fund an “unfair burden” (as set forth and described in Section 15(f) of the Investment Company Act) as a result of the Transactions, or any express or implied terms, conditions or understandings applicable thereto.

(f)                                    U.S. Public Fund Reorganizations.

(i)                                      Each party shall, and shall cause its subsidiaries to, use reasonable best efforts to, cooperate with each other to consummate the reorganization (each, a Fund Reorganization ) of the U.S. mutual funds sponsored by Henderson or its subsidiaries with the Janus Public Funds (each, a Reorganized Fund ), as agreed between Janus and Henderson, as of the Effective Time (including the preparation and filing of the necessary registration statement and/or prospectus or proxy statement (each, a Prospectus/Proxy Statement )).  In furtherance thereof, each party shall, and shall cause its subsidiaries to, use reasonable best efforts to: (A) as promptly as practicable after the date of this Agreement, (1) seek the approval of the board of trustees of each Reorganized Fund ( Fund Board Reorganization Approval ) of the applicable Fund Reorganization and (2) to the extent that approval by shareholders of such Reorganized Fund is required, request the Reorganized Fund’s board of trustees to recommend approval of the applicable Fund Reorganization  to the shareholders of the applicable Reorganized Fund and (B) to the extent that approval by shareholders of such Reorganized Fund is required, request the board of trustees of each Reorganized Fund to call a meeting of the shareholders of applicable Reorganized Fund for the purpose of voting on the approval of the Fund Reorganization for such Reorganized Fund (such shareholder meeting, a Fund Reorganization Shareholder Meeting ), such meeting to

63

occur as soon as practicable, subject to the requirements of Applicable Law, following the date of this Agreement.

(ii)                                   As promptly as reasonably practicable following the receipt of each Fund Board Reorganization Approval in Section 5.1(f)(i), each party shall, and shall cause its subsidiaries to, use reasonable best efforts to, request the board of trustees of each Reorganized Fund to: (A) with respect to each Reorganized Fund that is an acquiring fund, prepare and file the Prospectus/Proxy Statement for such Fund Reorganization; (B) to the extent that approval by shareholders of such Reorganized Fund is required, in accordance with Applicable Law cause a Prospectus/Proxy Statement to be mailed to the shareholders of the applicable Reorganized Fund as of the record date established by the Reorganized Fund’s board of trustees for such Fund Reorganization Shareholder Meeting; and (C) to the extent that approval by shareholders of such Reorganized Fund is required, duly call, convene and hold such Reorganized Fund’s Fund Reorganization Shareholder Meeting as promptly as reasonably practicable following the mailing of the Prospectus/Proxy Statement. With respect to each Reorganized Fund for which approval by shareholders is required to implement a Fund Reorganization, each party shall use its reasonable best efforts to request the board of trustees of such Reorganized Fund to solicit from the shareholders of proxies in favor of the approval of its Fund Reorganization.  Each of Janus and Henderson shall have the right to review in advance and to approve (such approval not to be unreasonably withheld) all the information relating to it or its affiliates proposed to appear in (A) any Prospectus/Proxy Statement or  any other proxy statements or materials or any amendment or supplement thereto submitted to the SEC or such other applicable Governmental Entity in connection with the approvals contemplated by this Section 5.1(f) or (B) any other materials sent or made available to shareholders of any Reorganized Fund in connection with such approvals.

(iii)                                Each party shall cooperate with the other party and its subsidiaries in taking the actions and obtaining the approvals described in Section 5.1(f) and shall furnish to each other, its subsidiaries and respective Representatives (as defined herein) such information and assistance as the other party, its subsidiaries and their respective Representatives may reasonably request in connection with seeking the approval described in this Section 5.1(f), including making directors, officers and employees of such party and its subsidiaries reasonably available for presentations to the Reorganized Fund’s board of trustees and for assisting, at the other party’s, its subsidiaries’ or their respective Representatives’ request, in the preparation of Prospectus/Proxy Statements or any other proxy statements or materials, any presentations or other materials, or any communications to be made to a Reorganized Fund’s board of trustees or shareholders or otherwise in furtherance of taking the actions and obtaining the approvals described in Section 5.1(f).  Each party agrees that none of the information

64

Section 5.2                                    No Solicitation by Janus

(a)                                  Subject to the other provisions of this Agreement (including this Section 5.2 ), Janus shall not, shall not authorize or permit any of its controlled Affiliates or any of its or their officers, directors or employees to, and shall use its reasonable best efforts to cause any investment banker, financial advisor, attorney, accountant or other representative (a Representative ) retained by it or any of its controlled Affiliates not to, directly or indirectly through another person, (i) solicit, initiate or knowingly encourage (including by furnishing information in connection with any inquiry or proposal with respect to a Janus Alternative Transaction (as defined herein)), or knowingly take any other action designed to facilitate, any inquiries regarding, or the making of, any proposal the consummation of which would constitute a Janus Alternative Transaction, (ii) engage or participate in any discussions or negotiations regarding any proposal the consummation of which would constitute a Janus Alternative Transaction, except to notify such person (or group of persons) as to the existence of the provisions of this Section 5.2 , or (iii) resolve, propose or agree to do any of the foregoing. Notwithstanding the immediately preceding sentence, if, at any time prior to obtaining the Janus Stockholder Approval, the Board of Directors of Janus determines in good faith (after consultation with outside counsel and a financial advisor of US or UK nationally recognized reputation) that any such proposal that did not result from a material breach of this Section 5.2(a)  constitutes or could reasonably be expected to result in a Janus Superior Proposal (as defined herein), subject to compliance with Section 5.2(c) , Janus and its Representatives may (A) furnish information with respect to Janus and its subsidiaries to the person (or group of persons) making such proposal (and its Representatives and financing sources) ( provided that all such information has previously been provided to Henderson or is promptly provided to Henderson prior to or substantially concurrent with the time

65

it is provided to such person) pursuant to a customary confidentiality agreement containing terms as to confidentiality (it being understood that such confidentiality agreement need not include any “standstill” or other similar terms that prohibit the counterparty thereto or any of its Affiliates or Representatives from making any proposal for a Janus Alternative Transaction, acquiring Janus or taking any other similar action, but shall not prohibit Janus from providing information to Henderson prior to or substantially concurrent with the time it is provided to such person, as provided above) that are generally no less restrictive to such person (or group of persons) than the terms of the confidentiality agreement, dated June 24, 2016, as amended, entered into between Janus and Henderson (the Confidentiality Agreement ), and (B) participate in discussions or negotiations regarding such proposal with the person (or group of persons) making such proposal (and its Representatives and financing sources).

For purposes of this Agreement, Janus Alternative Transaction means any of (i) a transaction or series of transactions pursuant to which any person (or group of persons) other than Henderson or its subsidiaries (including Merger Sub) (such person (or group of persons), a Janus Third Party ), acquires or would acquire, directly or indirectly, beneficial ownership (as defined in Rule 13d-3 under the Exchange Act) of more than 20% of the issued and outstanding shares of Janus Common Stock or securities (or options, rights or warrants to purchase, or securities convertible into or exchangeable for, such securities) representing 20% or more of the voting power of Janus, whether from Janus or pursuant to a tender offer or exchange offer or otherwise, (ii) a merger, consolidation, share exchange or other transaction pursuant to which any Janus Third Party acquires or would acquire, directly or indirectly, assets or businesses of Janus or any of its subsidiaries representing 20% or more of the revenues, net income or assets (in each case on a consolidated basis) of Janus and its subsidiaries taken as a whole or (iii) any disposition of assets to a Janus Third Party representing 20% or more of the revenues, net income or assets (in each case on a consolidated basis) of Janus and its subsidiaries, taken as a whole.

(b)                                  Except as permitted by this Section 5.2(b) , neither the Board of Directors of Janus nor any committee thereof shall (i) withdraw, qualify or modify, or propose publicly to withdraw, qualify or modify, or fail to make, in each case in a manner adverse to Henderson, the approval or recommendation by such Board of Directors or such committee of the Merger or this Agreement, (ii) approve or recommend, or propose publicly to approve or recommend, any Janus Alternative Transaction (any action in clause (i)  or this clause (ii)  being referred to as a Janus Recommendation Change ) ( provided , that nothing herein shall restrict or otherwise limit Janus from making accurate disclosure to its stockholders of factual information regarding the business, financial condition or results of operations of Janus or, so long as Janus provides Henderson with reasonable advance notice and a copy of the proposed disclosure, the fact that a proposal the consummation of which would constitute a Janus Alternative Transaction has been made, the identity of the party making such proposal or the material terms of such proposal (and such disclosure shall not be deemed to be a Janus

66

Recommendation Change), so long as none of the disclosure through which such factual information is conveyed, individually or in the aggregate, is contrary to or materially inconsistent with, in any respects, the recommendation made by the Janus Board of Directors), or (iii) cause Janus or any of its controlled Affiliates to enter into any letter of intent, agreement in principle, acquisition agreement or other agreement related to any Janus Alternative Transaction (other than a confidentiality agreement referred to in Section 5.2(a) ).  Notwithstanding the immediately preceding sentence, in the event that, prior to obtaining the Janus Stockholder Approval, the Board of Directors of Janus determines in good faith, after it has received a proposal that if consummated would be a Janus Superior Proposal (and after consultation with outside counsel and a financial advisor of US or UK nationally recognized reputation) that the failure to do so would be reasonably likely to be inconsistent with its fiduciary duties under Applicable Law, the Board of Directors of Janus may (subject to compliance with this and the following sentences in this Section 5.2(b) ) effect a Janus Recommendation Change from and after the day that is after the fourth Business Day following Henderson’s receipt of written notice from Janus advising Henderson that the Board of Directors of Janus has received a Janus Superior Proposal specifying the material terms and conditions of such Janus Superior Proposal, identifying the person making such Janus Superior Proposal and stating that it intends to make a Janus Recommendation Change; provided that in the event of a subsequent modification to the material terms and conditions of such Janus Superior Proposal, the Board of Directors of Janus may only effect a Janus Recommendation Change after the later of (x) the fourth Business Day following Henderson’s receipt of the initial written notice advising Henderson of the Janus Superior Proposal and (y) the second Business Day following Henderson’s receipt of written notice from Janus advising Henderson of the modification to such terms and conditions; and provided further that during such four or two Business Day notice period, as applicable, Janus engages (to the extent requested by Henderson) in good faith negotiations with Henderson to amend this Agreement in such a manner that the proposal to enter into a Janus Alternative Transaction no longer constitutes a Janus Superior Proposal.  For purposes of this Agreement, a Janus Superior Proposal means any bona fide written proposal (on its most recently amended or modified terms, if amended or modified) made by a Janus Third Party to enter into a Janus Alternative Transaction (with all references to 20% in the definition of Janus Alternative Transaction being treated as references to 50% for these purposes) that (A) did not result from a material breach of Section 5.2(a) , (B) is on terms that the Board of Directors of Janus determines in good faith (after consultation with outside counsel and a financial advisor of US or UK nationally recognized reputation) to be superior, from a financial point of view, to Janus’s stockholders than the Transactions, taking into account all terms and conditions of such proposal (including any changes to this Agreement that may be proposed by Henderson in response to such proposal to enter into a Janus Alternative Transaction), and (C) the conditions to the consummation of which are reasonably capable of being satisfied and is otherwise reasonably likely to be consummated, taking into account all financial, regulatory, legal and other aspects of such

67

proposal.  In addition, notwithstanding anything in this Agreement to the contrary, at any time prior to the receipt of the Janus Stockholder Approval, if the Board of Directors of Janus determines in good faith (after consultation with outside counsel and a financial advisor of US or UK nationally recognized reputation) that it is required to do so pursuant to its fiduciary duties under Applicable Law, the Board of Directors of Janus may effect a Janus Recommendation Change, but only at a time that is after the fourth Business Day following Henderson’s receipt of written notice from Janus advising Henderson of all material information with respect to the basis for any such Janus Recommendation Change and stating that it intends to make a Janus Recommendation Change and providing its rationale therefor.

(c)                                   In addition to the obligations of Janus set forth in Section 5.2(a)  and Section 5.2(b) , Janus shall promptly, and in any event within 24 hours of receipt thereof, advise Henderson orally and in writing of any request for substantive information or of any proposal relating to a Janus Alternative Transaction, the material terms and conditions of such request or proposal (including any changes thereto) and the identity of the person making such request or proposal.  Janus shall (i) keep Henderson reasonably informed of the status and details (including amendments or proposed amendments) of any such request or proposal on a current basis and (ii) provide to Henderson as soon as reasonably practicable after receipt or delivery thereof copies of all material substantive correspondence and other material written materials exchanged between Janus or its subsidiaries or any of their Representatives, on the one hand, and any person making such request or proposal, on the other hand, in each case that describes in any material respect any of the material terms or conditions of any such request or proposal.

(d)                                  Nothing contained in this Section 5.2 shall prohibit Janus or the Janus Board of Directors from (i) taking and disclosing to its stockholders a position contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act, or from issuing a “stop, look and listen” statement or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act pending disclosure of its position thereunder or (ii) otherwise complying with Applicable Law; provided , however, that any disclosure or statement that constitutes or contains a Janus Recommendation Change shall be subject to the provisions of Section 5.2(b) .

Section 5.3                                    No Solicitation by Henderson

(a)                                  Subject to the other provisions of this Agreement (including this Section 5.3 ), Henderson shall not, shall not authorize or permit any of its controlled Affiliates or any of its or their officers, directors or employees to, and shall use its reasonable best efforts to cause any Representatives retained by it or any of its controlled Affiliates not to, directly or indirectly through another person, (i) solicit, initiate or knowingly encourage (including by furnishing information in connection with any inquiry or proposal with respect to a Henderson Alternative Transaction (as defined herein)), or knowingly take any other action designed to

68

facilitate, any inquiries regarding, or the making of, any proposal the consummation of which would constitute a Henderson Alternative Transaction, (ii) engage or participate in any discussions or negotiations regarding any proposal the consummation of which would constitute a Henderson Alternative Transaction, except to notify such person (or group of persons) as to the existence of the provisions of this Section 5.3 , or (iii) resolve, propose or agree to do any of the foregoing.  Notwithstanding the immediately preceding sentence, if, at any time prior to obtaining the Henderson Shareholder Approvals, the Board of Directors of Henderson determines in good faith (after consultation with outside counsel and a financial advisor of US or UK nationally recognized reputation) that any such proposal that did not result from a material breach of this Section 5.3(a)  constitutes or could reasonably be expected to result in a Henderson Superior Proposal (as defined herein), subject to compliance with Section 5.3(c) , Henderson and its Representatives may (A) furnish information with respect to Henderson and its subsidiaries to the person (or group of persons) making such proposal (and its Representatives and financing sources) ( provided that all such information has previously been provided to Janus or is promptly provided to Janus prior to or substantially concurrent with the time it is provided to such person) pursuant to a customary confidentiality agreement containing terms as to confidentiality (it being understood that such confidentiality agreement need not include any “standstill” or other similar terms that prohibit the counterparty thereto or any of its Affiliates or Representatives from making any proposal for a Janus Alternative Transaction, acquiring Janus or taking any other similar action, but shall not prohibit Henderson from providing information to Janus prior to or substantially concurrent with the time it is provided to such person, as provided above) that are generally no less restrictive to such person (or group of persons) than the terms of the Confidentiality Agreement and (B) participate in discussions or negotiations regarding such proposal with the person (or group of persons) making such proposal (and its Representatives and financing sources).

For purposes of this Agreement, Henderson Alternative Transaction means any of (i) a transaction or series of transactions pursuant to which any person (or group of persons) other than Janus or its subsidiaries (such person (or group of persons), a Henderson Third Party ), acquires or would acquire, directly or indirectly, beneficial ownership (as defined in Rule 13d-3 under the Exchange Act) of more than 20% of the issued and outstanding Henderson Ordinary Shares or securities (or options, rights or warrants to purchase, or securities convertible into or exchangeable for, such securities) representing 20% or more of the voting power of Henderson, whether from Henderson or pursuant to a tender offer or exchange offer or otherwise, (ii) a merger, consolidation, share exchange or other transaction pursuant to which any Henderson Third Party acquires or would acquire, directly or indirectly, assets or businesses of Henderson or any of its subsidiaries representing 20% or more of the revenues, net income or assets (in each case on a consolidated basis) of Henderson and its subsidiaries taken as a whole or (iii) any disposition of assets to a Henderson Third Party representing 20% or more of the revenues, net income or assets (in each case on a consolidated basis) of Henderson and its subsidiaries, taken as a whole.

69

(b)                                  Except as permitted by this Section 5.3(b) , neither the Board of Directors of Henderson nor any committee thereof shall (i) withdraw, qualify or modify, or propose publicly to withdraw, qualify or modify, or fail to make, in each case in a manner adverse to Janus, the approval or recommendation by such Board of Directors or such committee of the Henderson Share Issuance, the Henderson Name Change, the Henderson Amended Articles, the Henderson Shareholder De-listing Approval, the Henderson Shareholder Permitted Henderson Dividend Approval or this Agreement, (ii) approve or recommend, or propose publicly to approve or recommend, any Henderson Alternative Transaction (any action in clause (i)  or this clause (ii)  being referred to as a Henderson Recommendation Change ) ( provided , that nothing herein shall restrict or otherwise limit Henderson from making accurate disclosure to its stockholders of factual information regarding the business, financial condition or results of operations of Henderson or, so long as Henderson provides Janus with reasonable advance notice and a copy of the proposed disclosure, the fact that a proposal the consummation of which would constitute a Henderson Alternative Transaction has been made, the identity of the party making such proposal or the material terms of such proposal (and such disclosure shall not be deemed to be a Henderson Recommendation Change), so long as none of the disclosure through which such factual information is conveyed, individually or in the aggregate, is contrary to or materially inconsistent with, in any respects, the recommendation made by the Henderson Board of Directors), or (iii) cause Henderson or any of its controlled Affiliates to enter into any letter of intent, agreement in principle, acquisition agreement or other agreement related to any Henderson Alternative Transaction (other than a confidentiality agreement referred to in Section 5.3(a) ).  Notwithstanding the immediately preceding sentence, in the event that, prior to obtaining the Henderson Shareholder Approvals, the Board of Directors of Henderson determines in good faith, after it has received a proposal that if consummated would be a Henderson Superior Proposal (and after consultation with outside counsel and a financial advisor of US or UK nationally recognized reputation) that the failure to do so would be reasonably likely to be inconsistent with its fiduciary duties under Applicable Law, the Board of Directors of Henderson may (subject to compliance with this and the following sentences in this Section 5.3(b) ) effect a Henderson Recommendation Change from and after the day that is after the fourth Business Day following Janus’s receipt of written notice from Henderson advising Janus that the Board of Directors of Henderson has received a Henderson Superior Proposal specifying the material terms and conditions of such Henderson Superior Proposal, identifying the person making such Henderson Superior Proposal and stating that it intends to make a Henderson Recommendation Change; provided that in the event of a subsequent modification to the material terms and conditions of such Henderson Superior Proposal, the Board of Directors of Henderson may only effect a Henderson Recommendation Change after the later of (x) the fourth Business Day following Janus’s receipt of the initial written notice advising Janus of the Henderson Superior Proposal and (y) the second Business Day following Janus’s receipt of written notice from Henderson advising Janus of the modification to such terms

70

and conditions; and provided further that during such four or two Business Day notice period, as applicable, Henderson engages (to the extent requested by Janus) in good faith negotiations with Janus to amend this Agreement in such a manner that the proposal to enter into a Henderson Alternative Transaction no longer constitutes a Henderson Superior Proposal.  For purposes of this Agreement, a Henderson Superior Proposal means any bona fide written proposal (on its most recently amended or modified terms, if amended or modified) made by a Henderson Third Party to enter into a Henderson Alternative Transaction (with all references to 20% in the definition of Henderson Alternative Transaction being treated as references to 50% for these purposes) that (A) did not result from a material breach of Section 5.3(a) , (B) is on terms that the Board of Directors of Henderson determines in good faith (after consultation with outside counsel and a financial advisor of US or UK nationally recognized reputation) to be superior, from a financial point of view, to Henderson’s shareholders than the Transactions, taking into account all terms and conditions of such proposal (including any changes to this Agreement that may be proposed by Janus in response to such proposal to enter into a Henderson Alternative Transaction), and (C) the conditions to the consummation of which are reasonably capable of being satisfied and is otherwise reasonably likely to be consummated, taking into account all financial, regulatory, legal and other aspects of such proposal.  In addition, notwithstanding anything in this Agreement to the contrary, at any time prior to the receipt of the Henderson Shareholder Approval, if the Board of Directors of Henderson determines in good faith (after consultation with outside counsel and a financial advisor of US or UK nationally recognized reputation) that it is required to do so pursuant to its fiduciary duties under Applicable Law, the Board of Directors of Henderson may effect a Henderson Recommendation Change, but only at a time that is after the fourth Business Day following Janus’s receipt of written notice from Henderson advising Janus of all material information with respect to the basis for any such Henderson Recommendation Change and stating that it intends to make a Henderson Recommendation Change and providing its rationale therefor.

(c)                                   In addition to the obligations of Henderson set forth in Section 5.3(a)  and Section 5.3(b) , Henderson shall promptly, and in any event within 24 hours of receipt thereof, advise Janus orally and in writing of any request for substantive information or of any proposal relating to a Henderson Alternative Transaction, the material terms and conditions of such request or proposal (including any changes thereto) and the identity of the person making such request or proposal.  Henderson shall (i) keep Janus reasonably informed of the status and details (including amendments or proposed amendments) of any such request or proposal on a current basis and (ii) provide to Janus as soon as reasonably practicable after receipt or delivery thereof copies of all material substantive correspondence and other material written materials exchanged between Henderson or its subsidiaries (including Merger Sub) or any of their Representatives, on the one hand, and any person making such request or proposal, on the other hand, in each case that describes in any material respect any of the material terms or conditions of any such request or proposal.

71

(d)                                  Nothing contained in this Section 5.3 shall prohibit Henderson or the Henderson Board of Directors from making any public announcement as referred to in Rule 2.3(d) of the City Code on Takeovers and Mergers; provided , however, that any disclosure or statement that constitutes or contains a Henderson Recommendation Change shall be subject to the provisions of Section 5.3(b) .

(e)                                   The parties agree that if the UK Panel on Takeovers and Mergers determines that Section 5.3(b)  requires Henderson to take or not to take action, whether as a direct obligation or as a condition to any other person’s obligation (however expressed), that is not permitted by Rule 21.2 of the City Code on Takeovers and Mergers, that provision shall have no effect and shall be disregarded (it being agreed and understood that Henderson shall consult with Janus, to the extent reasonable practicable, in connection with any discussion with the UK Panel on Takeovers and Mergers relating to the foregoing).  In the event that the UK Panel on Takeovers and Mergers makes a determination, the effect of which is that all or any portion of Section 5.3(b)  has no effect or is otherwise disregarded, the parties agree that Section 5.2(b)  shall be amended (without further action by the parties) to the same extent as Section 5.3(b) .

(g)                                   Each party agrees that notwithstanding anything in this Agreement to the contrary (other than with respect to claims for, or arising out of or in connection with, a Willful Breach hereof), (i) in the event that any Termination Fee is paid to a party in accordance with this Section 8.2 , the payment of such Termination Fee shall be the sole and exclusive remedy of such party, its subsidiaries, stockholders, Affiliates, officers, directors, employees and Representatives against the other party or any of its Representatives or Affiliates for, and (ii) in no event will the

94

party being paid any Termination Fee or any other such person seek to recover any other money damages or seek any other remedy based on a claim in law or equity with respect to, in each case of clauses (i)  and (ii) , (A) any loss suffered, directly or indirectly, as a result of the failure of the Merger to be consummated, (B) the termination of this Agreement, (C) any liabilities or obligations arising under this Agreement, or (D) any claims or actions arising out of or relating to any breach, termination or failure of or under this Agreement, and (iii) upon payment of any Termination Fee in accordance with this Section 8.2 , no party nor any Affiliates or Representatives of any party shall have any further liability or obligation to the other party relating to or arising out of this Agreement or the Transactions; provided that the Confidentiality Agreement shall survive any termination of this Agreement in accordance with its terms.

(h)                                  The parties acknowledge and agree that the amount of the overall loss that Janus or Henderson may incur in the circumstances in which any Termination Fee is payable under this Section 8.2 is not possible to ascertain as at the date of this Agreement and that, as such, the Termination Fee represents a genuine estimate by the parties of the amount of the overall loss that Janus or Henderson (as the case may be) would incur in the circumstances in which a Termination Fee is payable to Janus or the Henderson.  The parties shall use their reasonable best efforts to secure that any Expenses Reimbursement and any Termination Fee payable under this Section 8.2 (for the purposes of this Section 8.2(h)  a Relevant Sum ) will not be subject to any tax imposed in compliance with the Council Directive of 28 November 2006 on the common system of value added tax (EC Directive 2006/112) and any other tax of a similar nature whether imposed in a member state of the European Union in substitution for, or levied in addition to, such tax, or imposed elsewhere ( VAT ).  However, if it is finally determined by a Taxing Authority or tribunal or court of competent jurisdiction that a Relevant Sum constitutes all or part of the consideration for a supply made for VAT purposes then if that VAT is held to be chargeable by the payor of the Relevant Sum (or the representative member of the VAT group of which the payor is a party) under the reverse charge mechanism, to the extent that any VAT so chargeable is not recoverable by such payor (or the representative member of the VAT group of which the payor is a member) by repayment or credit, the Relevant Sum shall be reduced so that the aggregate of the Relevant Sum and such irrecoverable reverse charge VAT equals the Relevant Sum that would have been paid had no such irrecoverable reverse charge VAT arisen.  Such adjusting payment as may be required between the parties to give effect to this Section 8.2(h)  shall be made five Business Days after the date on which the final determination has been communicated to the party required to make the payment (together with such evidence of it as it is reasonable in the circumstances to provide) or, if later five Business Days before the VAT is required to be accounted for.  The party paying the Relevant Sum shall (or shall procure that the representative member of the VAT group of which such party is a member shall) use its reasonable endeavors to obtain any available repayment or credit in respect of VAT (as referred to in this Section 8.2(h) ) and for the purposes of this Section

95

8.2(h)  the extent of such repayment or credit shall be determined by such party, or the relevant representative member of the VAT group, acting reasonably.

Section 8.3                                    Amendment

Subject to compliance with Applicable Law, this Agreement may be amended by the parties hereto at any time before or after the Janus Stockholder Approval or the Henderson Shareholder Approvals; provided , however, that (a) after any such approval, there may not be, without further approval of the stockholders of Janus (in the case of the Janus Stockholder Approval) and the shareholders of Henderson (in the case of the Henderson Shareholder Approvals), any amendment of this Agreement that changes the amount or the form of the consideration to be delivered to the holders of Janus Common Stock hereunder or that by Applicable Law otherwise expressly requires the further approval of the stockholders of Janus or shareholders of Henderson, as the case may be, and (b) except as provided above, no amendment of this Agreement shall be submitted to be approved by the stockholders of Janus or the shareholders of Henderson.  This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto and duly approved by the parties’ respective Boards of Directors or a duly authorized committee thereof.

Section 8.4                                    Extension; Waiver

At any time prior to the Effective Time, a party hereto may, subject to the proviso of Section 8.3 (and for this purpose treating any waiver referred to below as an amendment), (a) extend the time for the performance of any of the obligations or other acts of the other parties, (b) waive any inaccuracies in the representations and warranties of the other parties contained in this Agreement or in any document delivered pursuant to this Agreement, (c) waive compliance by the other party with any of the agreements or conditions contained in this Agreement or (d) waive the satisfaction of any of the conditions contained in this Agreement.  No extension or waiver by Janus or Henderson shall require the approval of the stockholders of Janus or the shareholders of Henderson, respectively, unless such approval is required by Applicable Law.  Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party.  Any extension or waiver given in compliance with this Section 8.4 or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.
