Limited, Tristone Capital Inc., UBS Securities Canada Inc., Cormark Securities Inc. and Dundee Securities Corporation (collectively, the “Underwriters”) understand that Baytex Energy Trust (the “Trust”) proposes to issue and sell 6,900,000 trust units (the “Initial Trust Units”) pursuant to this Agreement.

Subject to the terms and conditions hereof, the Underwriters hereby severally, and not jointly, agree to purchase the Initial Trust Units from the Trust at the Closing Time (as hereinafter defined) in the respective percentages set forth in paragraph 16 hereof, and the Trust hereby agrees to issue and sell all but not less than all of the Initial Trust Units to the Underwriters at the Closing Time at the purchase price of $14.50 per Initial Trust Unit for gross proceeds of $100,050,000.00.  In addition, subject to the terms and conditions hereof, the Trust hereby grants to the Underwriters an option (the “Underwriters’ Option”), exercisable in full or in part for a period of thirty (30) days on or following the Closing Time, to purchase up to an additional 1,035,000 trust units of the Trust (the “Additional Trust Units”) at a price of $14.50 per Additional Trust Unit for additional aggregate gross proceeds of up to $15,007,500.00, if the Underwriters’ Option is exercised in full, and the Trust hereby agrees to issue and sell to the Underwriters and the Underwriters agree to purchase that number of Additional Trust Units set out in the notice of exercise on the basis provided herein and may arrange substitute purchasers for such Additional Trust Units as contemplated herein.  After reasonable efforts have been made to sell all of the Initial Trust Units at the purchase price of $14.50 per Initial Trust Unit, the Underwriters may subsequently reduce the purchase price to investors from time to time in order to sell any Initial Trust Units remaining unsold.  Any such reduction in the purchase price of the Initial Trust Units shall not affect the proceeds received by the Trust pursuant offering contemplated herein.

The Underwriters’ Option may be exercised by the Underwriters in full or in part by the Lead Underwriter delivering notice to the Trust (the “Underwriters’ Notice”) not later than thirty (30) days following the Closing Time, which notice shall specify the number of Additional Trust Units to be purchased by the Underwriters and the date and time at which such Additional Trust Units are to be purchased (the “Additional Closing Time”).  Such date may be the same as the Closing Date but not earlier than the later of: (i) the Closing Date; and (ii) two business days

after the date of such notice, nor later than five business days after the date of such notice.  Upon the Lead Underwriter furnishing the Underwriters’ Notice, the Trust will be committed to issue and sell, and the Underwriters will be obligated to purchase, in accordance with and subject to the provisions of this Agreement, the number of Additional Trust Units specified in the Underwriters’ Notice at the Additional Closing Time.

The Initial Trust Units, together with any Additional Trust Units that are issued upon exercise of the Underwriters’ Option, are referred to herein as the “Offered Units”.

The Underwriters understand that the net proceeds from the sale of the Offered Units will be used for the general purposes of the Trust.  In this regard, we understand that the Trust will prepare and file without delay, the Preliminary Prospectus (as hereinafter defined) relating to the sale of the Offered Units with the Securities Commissions and will obtain receipts therefor.  We understand that, in filing the Preliminary Prospectus, the Trust will select the Province of Alberta as the principal regulator under the Prospectus Review Procedures (as hereinafter defined).  We also understand that the Trust intends to take all steps and proceedings necessary, including the obtaining of any necessary rulings or orders, to complete and file, without delay, the Prospectus (as hereinafter defined) with such of the Securities Commissions, in accordance with their requirements in order to qualify the Offered Units for distribution (as hereinafter defined) in each of the Qualifying Provinces.

The Underwriters may, at their sole discretion, engage sub-agents (each, a “Selling Firm”) to act on their behalf and offer such Selling Firms any part of the Underwriting Fee (as hereinafter defined).  The Underwriters shall not be under any obligation to engage any Selling Firm.  To the extent that the Underwriters engage Selling Firms to act on their behalf, the Underwriters shall obtain undertakings from such Selling Firms to offer the Offered Units for sale to the public only as permitted by the Securities Laws, upon the terms and conditions set forth in the Prospectuses and as set forth herein.

the Trust by the Underwriters expressly for inclusion in the Preliminary Prospectus, the Prospectus or any Supplementary Material) which was or is alleged to be untrue or any omission or alleged omission to provide any information or state any fact (other than any information or fact relating solely to the Underwriters) the omission of which makes or is alleged to make any such information or statement untrue or misleading in light of the circumstances in which it was made;

(i) The Indemnified Party has been advised by counsel that there may be a reasonable legal defence available to the Indemnified Party which is different from or additional to a defence available to an Indemnifying Party and that representation of the Indemnified Party and any one or more of the Indemnifying Parties by the same counsel would be inappropriate due to the actual or potential differing interests between them (in which case the Indemnifying Parties shall not have the right to assume the defence of such proceedings on the Indemnified Party’s behalf);

(ii) the Indemnifying Parties shall not have taken the defence of such proceedings and employed counsel within ten (10) days after notice has been given to the Indemnifying Parties of commencement of such proceedings; or

(iii) the employment of such counsel has been authorized by the Indemnifying Parties in connection with the defence of such proceedings;

and, in any such event, the reasonable fees and expenses of such Indemnified Party’s counsel (on a solicitor and his client basis) shall be paid by the Indemnifying Parties, provided that the Indemnifying Parties shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate law firm (in addition to any local counsel) for all such Indemnified Parties.

(c) Each of the Indemnifying Parties hereby waives its rights to recover contribution from the Underwriters with respect to any liability of the Indemnifying Party by reason of or arising out of any misrepresentation in the Preliminary Prospectus, the Prospectus, any Supplementary Material or any other part of the Public

(d)

If any legal proceedings shall be instituted against an Indemnifying Party in respect of the Preliminary Prospectus, the Prospectus, any Supplementary Material or any other part of the Public Record, or if any regulatory authority or stock exchange shall carry out an investigation of an Indemnifying Party in respect of the Preliminary Prospectus, the Prospectus, any Supplementary Material or any other part of the Public Record, and, in either case, any Indemnified Party is required to testify, or respond to procedures designed to discover information, in connection with or by reason of the services performed by the Underwriters hereunder, the Indemnified Parties may employ their own legal counsel and the Indemnifying Parties shall pay and reimburse the Indemnified Parties for the reasonable fees, charges and disbursements (on a full indemnity basis) of such legal counsel, the other expenses reasonably incurred by the Indemnified Parties in connection with such proceedings or investigation and a fee at the normal per diem rate for any director, officer or employee of the Underwriters involved in the preparation for or attendance at such proceedings or investigation.

(e) The rights and remedies of the Indemnified Parties set forth in paragraphs 11 and 12 hereof are to the fullest extent possible in law cumulative and not alternative and the election by any Underwriter or other Indemnified Party to exercise any such right or remedy shall not be, and shall not be deemed to be, a waiver of any other rights and remedies.

(f) The Indemnifying Parties hereby acknowledge that the Underwriters are acting as agents for the Underwriters’ respective agents, directors, officers, shareholders and employees under this paragraph 11 and under paragraph 12 with respect to all such agents, directors, officers, shareholders and employees.

(g) The Indemnifying Parties waive any right they may have of first requiring an Indemnified Party to proceed against or enforce any other right, power, remedy or security or claim or to claim payment from any other person before claiming under this indemnity.  It is not necessary for an Indemnified Party to incur expense or make payment before enforcing such indemnity.

(h) The rights of indemnity contained in this paragraph 11 shall not apply if the Indemnifying Parties have complied with the provisions of paragraphs 3, 4 and 5 and the person asserting any claim contemplated by this paragraph 11 was not provided with a copy of the Prospectus or any amendment to the Prospectus or other document which corrects any misrepresentation or alleged misrepresentation which is the basis of such claim and which was required, under Canadian Securities Laws, to be delivered to such person by the Underwriters.

(i) If the Indemnifying Parties have assumed the defence of any suit brought to enforce a claim hereunder, the Indemnified Party shall provide the Indemnifying Parties copies of all documents and information in its possession pertaining to the claim, take all reasonable actions necessary to preserve its rights to object to or defend against the claim, consult and reasonably cooperate with the Indemnifying Parties in determining whether the claim and any legal proceeding resulting therefrom should be resisted, compromised or settled and reasonably cooperate and assist in any negotiations to compromise or settle, or in any defence of, a claim undertaken by the Indemnifying Parties.

12. Contribution

(a) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in this Agreement is due in accordance with its terms but is, for any reason, held by a court to be unavailable from one or more of the Indemnifying Parties on grounds of policy or otherwise, the Indemnifying Parties and the party or parties seeking indemnification shall contribute to the aggregate liabilities, claims, demands, losses (other than losses of profit), costs (including, without limitation, reasonable legal fees and disbursements on a full indemnity basis), damages and expenses to which they may be subject or which they may suffer or incur:

(i) in such proportion as is appropriate to reflect the relative benefit received by the Indemnifying Parties on the one hand, and by the Underwriters on the other hand, from the offering of the Offered Units; or

(ii) if the allocation provided by subparagraph 12(a) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in subparagraph 12(a) but also to reflect the relative fault of the Underwriters on the one hand, and the Indemnifying Parties, on the other hand, in connection with the statements, commissions or omissions or other matters which resulted in such liabilities, claims, demands, losses, costs, damages or expenses, as well as any other relevant equitable considerations.

(b) The relative benefits received by the Indemnifying Parties, on the one hand, and the Underwriters, on the other hand, shall be deemed to be in the same proportion that the total proceeds of the offering received by the Indemnifying Parties (net of fees but before deducting expenses) bear to the fees received by the Underwriters.  In the case of liability arising out of the Preliminary Prospectus, the Prospectus, any Supplementary Material or any other part of the Public Record, the relative fault of the Indemnifying Parties, on the one hand, and of the Underwriters, on the other hand, shall be determined by reference, among other things, to whether the misrepresentation or alleged misrepresentation, order, inquiry, investigation or other matter or thing referred to in paragraph 11 relates to information supplied or which ought to have been supplied by, or steps or actions taken or done on behalf of or which ought to have been taken or done on behalf of, one or more of the

- 29 -

Indemnifying Parties or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such misrepresentation or alleged misrepresentation, order, inquiry, investigation or other matter or thing referred to in paragraph 11.

(c)

The amount paid or payable by an Indemnified Party as a result of liabilities, claims, demands, losses (other than losses of profit), costs, damages and expenses (or claims, actions, suits or proceedings in respect thereof) referred to above shall, without limitation, include any legal or other expenses reasonably incurred by the Indemnified Party in connection with investigating or defending such liabilities, claims, demands, losses, costs, damages and expenses (or claims, actions, suits or proceedings in respect thereof) whether or not resulting in any action, suit, proceeding or claim.

(d) Each of the Indemnifying Parties and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Agreement were determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to in the immediately preceding paragraphs.  The rights to contribution provided in this paragraph 12 shall be in addition to, and without prejudice to, any other right to contribution which the Underwriters or other Indemnified Parties may have.

(e) Any liability of the Underwriters under this paragraph 12 shall be limited to the amount actually received by the Underwriters pursuant to paragraph 2 hereof.

13. Expenses

(a) Whether or not the offering of the Offered Units contemplated hereby is completed, the Trust will be responsible, subject to subparagraph 13(c), for all of the costs in connection with the offering, including without limitation the fees and expenses of counsel to the Trust Parties (including fees and expenses incurred by such counsel in connection with discussions with and opinions to the Underwriters and Underwriters’ counsel as part of the Underwriters’ due diligence investigations), auditors, transfer agents and outside consultants, filing fees, the costs and expenses of qualifying the Prospectuses in each of the Qualifying Provinces and the cost of preparing record books for all of the parties to this Agreement and their respective counsel.

(b) If the offering of the Offered Units contemplated hereby is not completed due to any reason whatsoever (unless such failure to complete is a result of a breach or default of the Underwriters), including, without limitation, the inability or unwillingness of the Trust or due to any of the Underwriters exercising the termination rights set forth herein, the Trust shall be responsible for the fees and expenses of Underwriters’ counsel and the expenses incurred by the Underwriters, including their expenses related to due diligence investigations (including the fees and expenses of any experts retained by the Underwriters in connection

- 30 -

	therewith), information meetings and travel (collectively, the “Underwriters’ Expenses”).
(c)	If the offering of the Offered Units contemplated hereby is completed, the Underwriters shall be responsible for the Underwriters’ Expenses.

(d) If the Underwriters are entitled to reimbursement for Underwriters’ Expenses hereunder, the Trust shall reimburse the Underwriters upon presentation of reasonable evidence of such expenses; the Underwriters shall present reasonable evidence of the Underwriters’ Expenses to the Trust as soon as is practicable following the termination of the offering and the Trust shall reimburse the Lead Underwriter, on behalf of the Underwriters, therefor, in accordance with subparagraph 13(b), within 30 days of receipt of reasonable evidence of the Underwriters’ Expenses.

14. Termination

(a) In addition to any other remedies which may be available to the Underwriters, the Underwriters (or any of them) shall be entitled, at their option, to terminate and cancel their obligations under this Agreement, without any liability on their part, by written notice to the Trust Parties, if prior to the Closing Time:

(i) any order to cease or suspend trading in any securities of the Trust or prohibiting or restricting the distribution of any of the Offered Units, is made, or any proceeding is announced, commenced or threatened for the making of any such order, by any securities regulatory authority, any stock exchange or by any other competent authority, and has not been rescinded, revoked or withdrawn;

(ii) any action, inquiry, suit, investigation or other proceeding (whether formal or informal) in relation to the Trust Parties, or any one of them, or any of their respective trustees, directors or senior officers is announced, commenced or threatened by any securities regulatory authority, any stock exchange or by any other competent authority, if, in the reasonable opinion of the Underwriters or any one of them, the announcement, commencement or threatening thereof adversely affects the trading or distribution of the Offered Units, the Trust Units or any other securities of the Trust;

(iii) there shall have occurred or have been discovered any adverse change or development, as determined by the Underwriters or any one of them in their sole discretion, acting reasonably, in the operations, capital or condition (financial or otherwise), business or business prospects of the Trust Parties (taken as a whole) or the respective properties, assets, prospects, liabilities or obligations (absolute, accrued, contingent or otherwise) of the Trust Parties (taken as a whole) that in the sole opinion of the Underwriters, or any of them, could reasonably be expected to have

- 31 -

a significant adverse effect on the market price or value of the Offered Units, the Trust Units or any other securities of the Trust;

(iv)

there should develop, occur or come into effect or existence or be announced any event, action, state, condition or occurrence of national or international consequence or any law, action or regulation or other occurrence of any nature whatsoever, which, in the sole opinion of the Underwriters or any one of them, acting reasonably, seriously adversely affects, or involves, or will seriously adversely affect, or involve, the financial markets generally or the business, operations or affairs of the Trust Parties (taken as a whole);

(v) the Underwriters shall become aware of any material information with respect to the Trust Parties which had not been publicly disclosed or disclosed in writing to the Underwriters at or prior to the date hereof which, in the sole opinion of the Underwriters or any one of them, acting reasonably, could be expected to have a material adverse effect on the market price or value of the Offered Units, the Trust Units or any other securities of the Trust;

(vi) any of the Trust Parties shall be in breach or default under or non-compliance with any representation, warranty, term or condition of this Agreement; or

(vii) there is announced any change or proposed change in applicable laws, regulations or policies or the interpretation or administration thereof and such change, in the sole opinion of the Underwriters, or any of them, could reasonably be expected to have a material adverse effect on the market price or value of the Offered Units, the Trust Units or any other securities of the Trust.

(b) The Underwriters, or any of them, may exercise any or all of the rights provided for in subparagraph 14(a) or paragraphs 9 or 19 notwithstanding any material change, change, event or state of facts and (except where the Underwriter purporting to exercise any of such rights is in breach of its obligations under this Agreement) notwithstanding any act or thing taken or done by the Underwriters or any inaction by the Underwriters, whether before or after the occurrence of any material change, change, event or state of facts including, without limitation, any act of the Underwriters related to the offering or continued offering of the Offered Units for sale and any act taken by the Underwriters in connection with any amendment to the Prospectus (including the execution of any amendment or any other Supplementary Material) and the Underwriters shall only be considered to have waived or be estopped from exercising or relying upon any of their rights under or pursuant to subparagraph 14(a) or paragraphs 9 or 19 if such waiver or estoppel is in writing and specifically waives or estops such exercise or reliance.

- 32 -

(c) Any termination pursuant to the terms of this Agreement shall be effected by notice in writing delivered to the Trust, provided that no termination shall discharge or otherwise affect any obligation of the Trust Parties under paragraphs 11, 12 or 13.

(d) If an Underwriter elects to terminate its obligations to purchase the Offered Units as aforesaid, whether the reason for such termination is within or beyond the control of the Trust Parties, the liability of the Trust Parties hereunder shall be limited to the indemnity referred to in paragraph 11, the contribution rights referred to in paragraph 12 and the payment of the expenses referred to in paragraph 13.

15. Authority to Lead Underwriter

The Trust Parties party hereto shall be entitled to and shall act on any notice, waiver, extension or communication given by or on behalf of the Underwriters by the Lead Underwriter, which shall represent the Underwriters and which shall have the authority to bind the Underwriters in respect of all matters hereunder, except in respect of any settlement under paragraphs 11 or 12, any matter referred to in paragraph 14, or any agreement under paragraph 16.  While not affecting the foregoing, the Lead Underwriter shall consult with the other Underwriters with respect to any such notice, waiver, extension or other communication.

16. Underwriters’ Obligations

(a) The Underwriters’ obligations to purchase the Offered Units at the Closing Time or the Additional Closing Time, if any, as the case may be, shall be several and not joint and several and the Underwriters’ respective obligations in this respect shall be in the following percentages of the aggregate principal amount of Trust Units to be purchased at that time:

TD Securities Inc.	27.54%
CIBC World Markets Inc.	12.25%
National Bank Financial Inc.	12.25%
RBC Dominion Securities Inc.	12.25%
Scotia Capital Inc.	12.25%
Canaccord Capital Corporation	6.12%
FirstEnergy Capital Corp.	6.12%
Raymond James Ltd.	3.06%
Peters & Co. Limited	2.04%
Tristone Capital Inc.	2.04%
UBS Securities Canada Inc.	2.04%
Cormark Securities Inc.	1.02%
Dundee Securities Corporation	1.02%

(b) If at the Closing Time or the Additional Closing Time, if any, as the case may be, any one or more of the Underwriters fail or refuse to purchase its respective percentage of the Offered Units, the remaining Underwriters shall be obligated

- 33 -

severally to purchase such Offered Units which the defaulting Underwriter or Underwriters have failed to purchase, in the proportion that the percentage set forth opposite the name of each of the remaining Underwriters bears to the aggregate of such percentages; provided, however, that in the event that the percentage of the total number of Offered Units which one or more of the Underwriters has failed to purchase exceeds 6.12% of the total number of Offered Units which the Underwriters have agreed to purchase, the other Underwriters shall have the right, but not the obligation, to purchase severally, on a pro rata basis as between themselves or in such other proportions as they may agree upon, all, but not less than all, of the Offered Units which would otherwise have been purchased by the Underwriters which fail to purchase.  In any such case either a non-defaulting Underwriter or the Trust shall have the right to postpone the Closing Time or the Additional Closing Time, if any, as the case may be, for such period, not exceeding five business days, in order that the required changes, if any, in the Prospectuses or in any other documents or arrangements may be effected.  If any non-defaulting Underwriter elects not to exercise such right and no other non-defaulting Underwriter elects to exercise such right so as to assume the entire obligations of the defaulting Underwriters and arrangements satisfactory to the Lead Underwriter (on behalf of the Underwriters) and the Trust for the purchase of such Offered Units are not made within 48 hours after such default, then (i) each non-defaulting Underwriter shall be entitled, by notice to the Trust, to terminate, without liability, its obligation to purchase its original percentage of the Offered Units and (ii) the Trust Parties shall have the right to terminate their obligations hereunder without liability on its part except under paragraphs 10, 11 and 12 hereof in respect of non-defaulting Underwriters.  Any action taken under this paragraph 16(b) shall not relieve any defaulting Underwriter from liability in respect of any default by such Underwriter under this Agreement.

(c)

Nothing in this paragraph 16 shall obligate the Trust to sell to one or any of the Underwriters less than all of the Offered Units or shall relieve any Underwriter in default from liability to the Trust Parties or to any non-defaulting Underwriters in respect of its default hereunder.  In the event of a termination by the Trust Parties of their obligations under this Agreement, there shall be no further liability on the part of the Trust Parties to the Underwriters except in respect of any liability which may have arisen or may thereafter arise under paragraphs 11, 12 and 13.

17. Use of Proceeds

Each of the Trust Parties hereby covenant and agree to use the net proceeds of the sale of the Offered Units hereunder in accordance with the disclosure in the Prospectus.

- 34 -

18. Underwriters’ Covenants

The Underwriters shall:

(a) use all reasonable efforts to complete the distribution of the Offered Units as soon as possible;

(b) not make use of any “green sheet” in respect of the Offered Units without approval of the Trust and shall comply with Canadian Securities Laws with respect to the use of “green sheets” and other marketing material during the waiting period;

(c) give prompt notice to the Trust, when, in the opinion of the Underwriters, distribution has ceased; and

(d) as soon as reasonably practicable and, in any event, within 30 days of the completion of the distribution, provide the Trust with a breakdown of the number of Offered Units sold in each jurisdiction where such information is required for the purpose of calculating filing fees payable.

19. Terms and Conditions

All representations, warranties, terms, covenants and conditions of this Agreement to be performed by the Trust shall be construed as conditions for the benefit of the Underwriters. Any breach of, default under, non-compliance with, or failure by any Trust Party to comply with, any such representation, warranty, covenant, term or condition shall entitle any Underwriter to terminate its obligations to purchase the Offered Units by giving written notice to that effect to the Trust at or prior to the Closing Time.  The Underwriters may waive in whole or in part, or extend the time for compliance with, any of such terms and conditions without prejudice to the Underwriters’ rights in respect of any other of such terms and conditions or any other or subsequent breach or non-compliance, provided that to be binding on the Underwriters any such waiver or extension must be in writing.  In the event of the termination of the Underwriters’ obligations pursuant to this paragraph 19, the Trust’s liability hereunder shall be limited to payment of such of the expenses referred to in paragraph 13 hereof payable by the Trust as shall previously have been incurred and to any liability which may have arisen or may thereafter arise under paragraphs 11 and 12.

20. U.S. Offers

In connection with offers and sales of the Offered Units in the United States, or to or for the account or benefit of U.S. Persons (as defined in Schedule “A” attached hereto):

(a) the Trust Parties make the representations, warranties and covenants applicable to them contained in Schedule “A” attached hereto, which representations, warranties and covenants shall be deemed to be incorporated by reference into this Agreement; and

- 35 -

(b) each of the Underwriters makes the representations, warranties and covenants applicable to it contained in Schedule “A” attached hereto, which representations, warranties and covenants shall be deemed to be incorporated by reference into this Agreement.

21. Future Offerings

The Trust shall not issue, agree to issue or announce an intention to issue any additional Trust Units or any securities convertible into or exchangeable for the Trust Units (except in connection with: (a) an acquisition made at “arms length”; (b) the exchange, transfer, conversion or exercise of rights of existing outstanding securities or existing commitments to issue securities; or (c) the issuance of Trust Units pursuant to the Trust’s distribution reinvestment plan or the issuance of rights or Trust Units upon the exercise of rights granted pursuant to the Trust’s unit rights incentive plan) for a period of 90 days from the Closing Date, without the prior consent of the Lead Underwriter, for and on behalf of the Underwriters, such consent not to be unreasonably withheld.

22. Stabilization

In connection with the distribution of the Offered Units, the Underwriters may over-allot or effect transactions which stabilize or maintain the market price of the Trust Units at levels other than those which might otherwise prevail in the open market, but in each case only as permitted by Canadian Securities Laws.  Such stabilizing transactions, if any, may be discontinued at any time.

23. Survival

The representations, warranties, covenants, indemnities and agreements of the Trust contained herein or delivered pursuant hereto shall survive the purchase by the Underwriters of the Offered Units and shall continue in full force and effect notwithstanding any subsequent disposition by the Underwriters of the Offered Units, and the Underwriters shall be entitled to rely on the representations and warranties of the Trust contained herein or delivered pursuant hereto notwithstanding any investigation which the Underwriters may undertake or which may be undertaken on the Underwriters’ behalf.

24. Further Assurances

Each party to this Agreement covenants agrees that, from time to time, it will, at the request of the requesting party, execute and deliver all such documents and do all such other acts and things as any party hereto, acting reasonably, may from time to time request be executed or done in order to better evidence or perfect or effectuate any provision of this Agreement or of any agreement or other document executed pursuant to this Agreement or any of the respective obligations intended to be created hereby or thereby.
