     The Company hereby confirms its agreement with the Placement Agent as follows:

          1. Agreement to Act as Placement Agent.

          (a) On the basis of the representations and warranties of the Company set forth in Section 4 hereof and subject to the terms and conditions set forth in this Agreement, the Company hereby engages the Placement Agent to act as the exclusive placement agent, on a reasonable efforts basis, in connection with the offer and sale by the Company of Shares to the Investors. As compensation for services rendered, at the time of purchase (as defined in Section 2 hereof) the Company shall pay to the Placement Agent, by Federal Funds wire transfer to an account or accounts designated by the Placement Agent, an amount equal to 4.5% of the gross proceeds received by the Company from the sale of the Shares at the time of purchase. The Shares are being sold at a price of $47.00 per share of Common Stock.

          (b) In soliciting purchases of Shares, the Placement Agent shall act solely, as the Company’s agent and not as principal, and this Agreement shall not give rise to any commitment by the Placement Agent or any of its affiliates to underwrite or purchase any of the Shares. Notwithstanding the foregoing, it is understood and agreed that the Placement Agent or its affiliates may, solely at their discretion and without any obligation to do so, purchase Shares as principals; provided, however, that any such purchases by the Placement Agent or its affiliates shall be fully disclosed to the Company, including the identity of such Investors, and accepted by the Company in accordance with Section 1(c).

          (c) Offers for the purchase of Shares may be solicited by the Placement Agent at such times and in such amounts as the Placement Agent deems advisable. The Placement Agent may also retain other brokers or dealers to act as sub-agents on its behalf in connection with the offering and sale of the Shares. Until the earlier of the time of purchase or the termination of this Agreement, the Company shall not, without the prior written consent of the Placement Agent, solicit or accept offers to purchase Shares

other than through the Placement Agent. The Placement Agent shall have no authority to bind the Company in respect of the sale of any Shares. The Placement Agent shall communicate, orally or in writing, to the Company each reasonable offer or indication of interest received by it to purchase Shares. The Company shall have the sole right to accept offers to purchase the Shares and may reject any such offer in whole or in part. The Placement Agent shall make commercially reasonable efforts to assist the Company in obtaining performance by each Investor whose offer to purchase Shares has been solicited by the Placement Agent and accepted by the Company, but the Placement Agent shall not be obligated to disclose the identity of any potential Investor or have any liability to the Company in the event any such purchase is not consummated for any reason. If the Company shall default in its obligation to deliver Shares to an Investor whose offer it has accepted, the Company shall indemnify and hold harmless the Placement Agent against any loss, claim, damage or expense arising from or as a result of such default by the Company.

          2. Payment and Delivery. Subject to the terms and conditions hereof, payment of the purchase price for the Shares shall be made at the office of Stephens Inc., 111 Center Street, Little Rock, Arkansas 72201 (or at such other place as shall be agreed upon by the Placement Agent and the Company), at 10:00 A.M., Central Daylight Time, on June 4, 2007, unless another time and date shall be agreed to by the Placement Agent and the Company. Subject to the terms and conditions hereof, payment of the purchase price for the Shares shall be made by the Investors against delivery of certificates for the Shares to the Investors. The Shares shall be registered in the names of the Investors and shall be in such denominations as are requested at least one business day prior to the date of closing by written notice from the Placement Agent to the Company. The time at which such payment and delivery are to be made is hereinafter sometimes called “the time of purchase.” Deliveries of the documents described in Section 6 hereof with respect to the purchase and delivery of the Shares shall be made at the office of Alston & Bird LLP at the time of purchase.

          (g) subsequent to the execution and delivery of this Agreement and prior to the time of purchase, there shall not have been (i) any event that has had, or that reasonably could be expected to have, a Material Adverse Effect, (ii) any transaction which is material to the Company or any Subsidiary and not disclosed in the Disclosure Package, except obligations and liabilities incurred in the ordinary course of business consistent with past practice, (iii) any obligation or liability, direct or contingent (including any off-balance sheet obligations), incurred by the Company or any Subsidiary, which is material to the Company and its Subsidiaries taken as a whole, except obligations and liabilities incurred in the ordinary course of business consistent with past practice, (iv) any change in the capital stock of the Company or any Subsidiary (except for the issuance of shares of Common Stock upon conversion of existing convertible securities and exercise by employees of existing stock options disclosed as outstanding in the Disclosure Package and the grant to employees, under the Company Stock Plans, of stock options and shares of restricted stock that are not exercisable or vested, as the case may be, during the Lock-up Period) or (v) any dividend or distribution of any kind declared, paid or made on the capital stock of the Company that, in each case, makes it, in the judgment of the Placement Agent, impracticable or inadvisable to market the Shares on the terms and in the manner contemplated in the Prospectus;

          8. Indemnification.

          (a) The Company agrees (i) to indemnify, defend and hold harmless the Placement Agent, its directors, officers, employees and representatives, and each person, if any, who controls the Placement Agent within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) (including the reasonable costs of investigation and defense) to which the Placement Agent or any such person may become subject, insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based (A) upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereto, including any information deemed to be a part thereof pursuant to Rule 430A, Rule 430B or Rule 430C under the Act, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, (B) upon any untrue statement or alleged untrue statement of a material fact contained in the Disclosure Package, any Issuer Free Writing

Prospectus, the Prospectus or any amendment or supplement thereto or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (C) in whole or in part upon any act or failure to act or alleged act or failure to act by the Placement Agent in reliance upon (A) or (B), and in connection with or relating in any manner to the Shares or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability, expense or action arising out of or based upon any matter covered by clause (A) or (B) above, and (ii) to reimburse the Placement Agent, its officers, directors, employees and representatives and each such controlling person for any and all expenses (including the fees and disbursements of counsel chosen by the Placement Agent) as such expenses are reasonably incurred by the Placement Agent or its officers, directors, employees and representatives or such controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability, expense or action to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by the Placement Agent expressly for use in the Registration Statement, the Disclosure Package, any Issuer Free Writing Prospectus, or the Prospectus (or any amendment or supplement thereto); and provided further, that such indemnity agreement shall not apply to any loss, claim, damage, liability, expense or action to the extent arising out of or based upon an untrue statement or omission of a material fact contained in the Disclosure Package or Prospectus which was corrected in a supplement to the Disclosure Package or Prospectus that was provided to the Placement Agent prior to the distribution by it of a term sheet that reflects the pricing and other final terms of the offering contemplated hereby. The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Company may otherwise have.

          (b) The Placement Agent agrees to indemnify and hold harmless the Company, each of its directors, officers, employees and representatives, and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) (including the reasonable cost of investigation and defense) to which the Company, or any such director, officer, employee, representative or controlling person may become subject, insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement, the Disclosure Package, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) or arises out of or is based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, and only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Disclosure Package, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written

information furnished to the Company by the Placement Agent expressly for use therein; and to reimburse the Company, or any such director, officer, employee, representative or controlling person for any and all expenses (including the fees and disbursements of counsel chosen by such indemnitee) reasonably incurred by the Company or any such director, officer, employee, representative, agent or controlling person in connection with investigating, defending, settling, compromising, appearing as a third party witness or paying any such loss, claim, damage, liability, expense or action. The Company hereby acknowledges that the only information that the Placement Agent has furnished to the Company expressly for use in the Registration Statement, the Disclosure Package, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) are the statements set forth in the second sentence of the third paragraph of the Prospectus Supplement under the caption “Plan of Distribution.” The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that the Placement Agent might otherwise have.

          (c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure to so notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any liability other than the indemnification obligation provided in paragraph (a) or (b) above. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded (based on the advice of counsel to the indemnified party) that a conflict exists between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for

the expenses of more than one separate counsel (other than local counsel), reasonably approved by the indemnifying party, representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

          (d) The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

          (e) To the extent the indemnification provided for in Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any loss, claim, damage, liability, expense or action referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage, liability, expense or action (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Placement Agent on the other hand from the offering of the Shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Placement Agent on the other hand in connection with the statements or omissions that resulted in such loss, claim, damage, liability, expense or action, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Placement Agent on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company and the total commissions received by the Placement Agent, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate net proceeds. The relative fault of the Company on the one hand and the Placement Agent on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Placement Agent and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

          (f) The Company and the Placement Agent agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in Section 8(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities, expenses and actions referred to in Section 8(e) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, the Placement Agent shall not be required to contribute any amount in excess of the amount by which the total price at which the Shares were sold and distributed to the public exceeds the amount of any damages that the Placement Agent has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

          (g) The indemnity and contribution provisions contained in this Section 8 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Placement Agent, any person controlling the Placement Agent or any affiliate of the Placement Agent or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) delivery of the Shares.

          9. Relationship of Parties.

The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Placement Agent with respect to any breach or alleged breach of fiduciary duty.

          (b) The Company will make available to the Placement Agent all information concerning the business, assets, operations and financial condition of the Company which the Placement Agent reasonably requests, and all such information shall be accurate and complete in all material respects.

Re: DXP Enterprises, Inc. (the “Company”)

Ladies and Gentlemen:

     The undersigned is an owner of record or beneficially of shares of Common Stock of the Company (“Common Stock”) or securities convertible into or exchangeable or exercisable for Common Stock. The Company proposes to issue and sell shares of its Common Stock (the “Offering”) for which you will act as the placement agent. The undersigned acknowledges that you are relying on the representations and agreements of the undersigned contained in this letter in carrying out the Offering and in entering into placement arrangements with the Company with respect to the Offering.

     In consideration of the foregoing, the undersigned hereby agrees that the undersigned will not (and will cause any spouse or immediate family member of the spouse or the undersigned living in the undersigned’s household not to), without the prior written consent of Stephens Inc. (“Stephens”) (which consent may be withheld in its sole discretion), directly or indirectly, sell, offer, contract or grant any option to sell (including without limitation any short sale), pledge, establish an open “put equivalent position” or liquidate or decrease a “call equivalent position” within the meaning of Rule 16a-1(h) under the Securities Exchange Act of 1934, as amended, or otherwise dispose of or transfer (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition or transfer of), including the filing (or participation in the filing) of a registration statement (except for a registration statement on Form S-8) with the Securities and Exchange Commission in respect of, any shares of Common Stock, options to acquire shares of Common Stock, or securities exchangeable or exercisable for or convertible into shares of Common Stock currently or hereafter owned either of record or beneficially (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended) by the undersigned (or such spouse or family member), or publicly announce an intention to do any of the foregoing, for a period commencing on the date hereof and continuing through the close of trading on the date 90 days after the date of the Prospectus Supplement relating to the Offering (the “Lock-Up Period”). The foregoing sentence shall not apply to (i) a sale of any or all of the shares of Common Stock owned by the undersigned pursuant to a “Rule 10b5-1 plan” of the undersigned, (ii) a bona fide gift or gifts or (iii) the transfer of any or all of the shares of Common Stock owned by the undersigned, either during his or her lifetime or on death, by gift,

will or intestate succession to the immediate family of the undersigned or to a trust the beneficiaries of which are exclusively the undersigned and/or a member or members of his or her immediate family; provided, however, that in each of (ii) and (iii) above, it shall be a condition to such transfer that the transferee executes and delivers to Stephens an agreement stating that the transferee is receiving and holding the Common Stock subject to the provisions of this letter agreement, and there shall be no further transfer of such Common Stock except in accordance with this letter. In addition, the undersigned agrees that, without the prior written consent of Stephens, it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock.

     If (i) the Company issues an earnings release or material news, or a material event relating to the Company occurs, during the last 17 days of the Lock-Up Period, or (ii) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, the restrictions imposed by this agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event, unless Stephens waives, in writing, such extension. The undersigned hereby acknowledges that the Company has agreed in the Placement Agency Agreement to provide notice of any event that would result in an extension of the Lock-Up Period pursuant to the previous paragraph to the undersigned (in accordance with Section 5(j) of the Placement Agency Agreement) and agrees that any such notice properly delivered will be deemed to have given to, and received by, the undersigned. The undersigned hereby further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this Lock-Up Agreement during the period from the date of this Lock-Up Agreement to and including the 34th day following the expiration of the initial Lock-Up Period, it will give notice thereof to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the Lock-Up Period (as such may have been extended pursuant to the previous paragraph) has expired.

     The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of shares of Common Stock or securities convertible into or exchangeable or exercisable for Common Stock held by the undersigned except in compliance with the foregoing restrictions.

     It is understood that if (a) the Company advises Stephens in writing that the parties do not intend to proceed with the Offering, (b) either the Company or Stephens shall advise the other party in writing that the Offering has been terminated, (c) the Placement Agency Agreement does not become effective, or (d) the Placement Agency Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock to be sold thereunder, then the undersigned will be released from all obligations under this letter.

     With respect to the Offering only, the undersigned waives any registration rights relating to registration under the Securities Act of 1933, as amended, of any Common Stock owned either

of record or beneficially by the undersigned, including any rights to receive notice of the Offering.

     This agreement is irrevocable and will be binding on the undersigned and the respective successors, heirs, personal representatives and assigns of the undersigned.
