(a)

HSE shall immediately cease and cause to be terminated all existing discussions and negotiations (including, without limitation, through any advisors or other parties on its behalf), with any parties (other than DXP and Acquiror) conducted before the date of this Agreement with respect to any proposal that constitutes, or may reasonably be expected to constitute or lead to, an Acquisition Proposal. HSE covenants, represents and warrants that it has not waived any confidentiality, non-solicitation or standstill provisions contained in any confidentiality, non-solicitation or standstill agreement with any Person. HSE shall immediately discontinue access to all of its confidential information and any data room, virtual and otherwise, and immediately request the return or destruction of all information provided to any third parties who have entered into a confidentiality agreement with HSE relating to an Acquisition Proposal and shall use all reasonable commercial efforts to ensure that such requests are honoured.

(b)	HSE shall not, directly or indirectly, do or authorize or permit any of its officers, directors, employees, advisors (financial and otherwise), experts or other representatives retained by it to do any of the following:

solicit, assist, initiate, encourage or in any way facilitate (including by way of furnishing information, or entering into any form of written or oral agreement, arrangement or understanding) any Acquisition Proposal or inquiries, discussions, negotiations, proposals or offers regarding an Acquisition Proposal;

(ii)

enter into or participate in any discussions or negotiations regarding an Acquisition Proposal, or furnish to any other Person any information with respect to its businesses, properties, operations, prospects or conditions (financial or otherwise) in connection with an Acquisition Proposal or otherwise cooperate in any way with, or assist or participate in, facilitate or encourage, any effort or attempt of any other Person to do or seek to do any of the foregoing;

(iii)

(vi)

enter into or participate in any discussions or negotiations with a third party who (without any solicitation, initiation or encouragement, directly or indirectly, after the date of this Agreement, by HSE or any of its officers, directors or employees or any financial advisor, expert or other representative retained by it) seeks to initiate such discussions or negotiations with HSE that do not result from a breach of this Section 7.1 and, subject to execution of a confidentiality and standstill agreement which in any event and taken as a whole is no less favourable to HSE than the HSE Confidentiality Agreement (provided that such confidentiality agreement shall provide for disclosure thereof (along with all information provided thereunder) to DXP and Acquiror as set out below), may furnish to such third party information concerning HSE and its business, properties and assets, in each case if, and only to the extent that:

(A)	the third party has first made an unsolicited written bona fide Acquisition Proposal which the HSE Board has determined is a Superior Proposal; and

(B)

prior to furnishing such information to or entering into or participating in any such discussions or negotiations with such third party, HSE provides prompt written notice to DXP and Acquiror to the effect that it is furnishing information to or entering into or participating in discussions or negotiations with such Person together with a copy of the confidentiality and standstill agreement referenced above and, if not previously provided to DXP and Acquiror (provided that if such information has been previously provided to DXP and Acquiror, such information will be identified in reasonable detail in such notice), copies of all information provided to such third party concurrently with the provision of such information to such third party, and provided further that HSE forthwith shall notify DXP and Acquiror, first orally and then promptly (and in any event within 24 hours) in writing, of any inquiries, offers or proposals with respect to a Superior Proposal (which written notice shall include, without limitation, a copy of any such proposal (and any amendments or supplements thereto), the identity of the Person making it, if not previously provided to DXP and Acquiror, copies of all information provided to such party and all other information reasonably requested by DXP and/or Acquiror), within 24 hours of the receipt thereof, shall keep DXP and Acquiror informed of the status and details of any such inquiry, offer or proposal and respond promptly to all of DXP’s and Acquiror’s questions with respect thereto; and

(vii)

accept, recommend, approve or enter into an agreement to implement a Superior Proposal from a third party, but only if prior to such acceptance, recommendation, approval or implementation:

(A)	HSE has complied with Section 7.1(c) and Section 7.1(d);

(B)

the HSE Board shall have concluded in good faith, after considering all proposals to adjust the terms and conditions of this Agreement as contemplated by Section 7.1(d) and after receiving the advice of outside counsel as reflected in minutes of the HSE Board, that the taking of such action is necessary for the HSE Board in discharge of its fiduciary duties under Applicable Laws; and

(C)	HSE terminates this Agreement in accordance with Section 8.2(a)(iv)(B), and concurrently therewith pays the HSE Termination Fee to Acquiror (or its designee).

(c)

HSE shall forthwith notify DXP and Acquiror (first orally and then promptly (and in any event within 24 hours) in writing) of any Acquisition Proposal (or any amendment thereto) or any proposal, inquiry or offer that could lead to an Acquisition Proposal, or any request for non-public information relating to HSE or its assets, or any amendments to the foregoing. Such notice shall include a copy of any written Acquisition Proposal (and any amendment thereto) which has been received or, if no written Acquisition Proposal has been received, a description of the material terms and conditions of, and the identity of the Person making any inquiry, proposal, offer or request. HSE shall also promptly and in any event within 24 hours provide such further and other details of the Acquisition Proposal or any amendment thereto as DXP and /or Acquiror may reasonably request. HSE shall keep DXP and Acquiror promptly and fully informed of the status, including any change to material terms, of any Acquisition Proposal or any amendment thereto, shall respond promptly to all inquiries by DXP and/or Acquiror with respect thereto, and shall provide DXP and Acquiror with copies of all material correspondence and other written material sent to or provided to HSE by any Person in connection with such inquiry, proposal, offer or request or sent or provided by HSE to any Person in connection with such inquiry, proposal, offer or request.

(d)

HSE shall give DXP and Acquiror, orally and in writing, at least five business days advance notice (a “Superior Proposal Notice”) of any decision by the HSE Board to accept, recommend, approve or enter into an agreement to implement a Superior Proposal, shall set out the reasonable determination of the HSE Board, in consultation with its financial advisors, of the financial value of the consideration offered by such third party to HSE Shareholders under such Superior Proposal, which notice shall confirm that the HSE Board has determined that such Acquisition Proposal constitutes a Superior Proposal, shall identify the third party making the Superior Proposal and provide a copy thereof and any amendments thereto. During the five business day period commencing on the day following delivery of such notice, HSE agrees not to accept, recommend, approve or enter into any agreement to implement such Superior Proposal and shall not withdraw, redefine, modify or change its recommendation in respect of the Arrangement. In addition, during such five business day period HSE shall, and shall cause its financial and legal advisors to, negotiate in good faith with DXP, Acquiror and their financial and legal advisors to make such adjustments in the terms and conditions of this Agreement and the Arrangement as would enable DXP and Acquiror to proceed with the Arrangement as amended rather than the Superior Proposal. In the event DXP and Acquiror propose to amend this Agreement and the Arrangement such that the Superior Proposal ceases to be a Superior Proposal and so advise the HSE Board prior to the expiry of such five business day period, the HSE Board shall not accept, recommend, approve or enter into any agreement to implement such Superior Proposal and shall not withdraw, redefine, modify or change its recommendation in respect of the Arrangement and DXP, Acquiror and HSE shall enter into an amended version of this Agreement reflecting such proposed amendments.

(e)

If required by DXP and Acquiror, HSE shall, subsequent to the five business day notice period contemplated by Section 7.1(d) (and in no case during such period) reaffirm its recommendation of the Arrangement by press release promptly in the event that (i) any Acquisition Proposal which is publicly announced is determined not to be a Superior Proposal; or (ii) the Parties have entered into an amended agreement pursuant to Section 7.1(d) which results in any Acquisition Proposal not being a Superior Proposal. HSE will afford DXP, Acquiror and their legal counsel a reasonable opportunity to review and comment on the form and content of any such press release, recognizing that whether or not such comments are appropriate will be determined by HSE, acting reasonably.

(f)

DXP and Acquiror agree that all information that may be provided to them by HSE with respect to any Acquisition Proposal pursuant to this Section 7.1 shall be treated as if it were "Confidential Information" as that term is defined in the HSE Confidentiality Agreement and shall not be disclosed or used except in accordance with the provisions of the HSE Confidentiality Agreement or in order to enforce their rights under this Agreement in legal proceedings.

(g)	HSE shall ensure that its officers, directors and employees and any investment bankers or other advisers or representatives retained by it are aware of the provisions of this Section 7.1 and shall be responsible for any breach of this Section 7.1 by any of them.

(h)	Nothing in this Agreement shall prevent the HSE Board from complying with section 2.17 of Multilateral Instrument 62-104 and similar provisions under applicable Canadian securities Laws relating to the provision of directors' circulars in respect of an Acquisition Proposal.

7.2	Access to Information; Confidentiality

From the date hereof until the earlier of the Effective Time and the termination of this Agreement pursuant to its terms, subject to compliance with applicable Law and the terms of any existing Contracts, HSE shall, and shall cause its Representatives to, afford to DXP, Acquiror and their Representatives such access as DXP and Acquiror may reasonably require at all reasonable times during normal office hours, including for the purpose of facilitating integration and business planning, to its officers, employees, agents, properties, books, records and contracts, and shall furnish DXP and Acquiror with all data and information as DXP and Acquiror may reasonably request. DXP and Acquiror acknowledge and agree that information furnished by HSE pursuant to this Section 7.2 shall be subject to the terms and conditions of the HSE Confidentiality Agreement.

(a)

Each Party will give prompt notice to the other of the occurrence, or failure to occur, at any time from the date hereof until the earlier to occur of the termination of this Agreement pursuant to its terms and the Effective Time of any event or state of facts which occurrence or failure would, or would be likely to:

(i)	cause any of the representations or warranties of such Party contained herein to be untrue or inaccurate in any material respect on the date hereof or at the Effective Time; or

(ii)	result in the failure to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by such Party hereunder prior to the Effective Time,

provided, however, that the delivery of any notice pursuant to this Section 7.3 shall not limit or otherwise affect the remedies available hereunder to the Party receiving that notice.

No Party may elect to not complete the transactions contemplated hereby pursuant to any termination right arising under Section 8.2(a)(iii)(B) or Section 8.2(a)(iv)(A) and no payments are payable as a result of such termination pursuant to Section 8.3 unless, prior to the Effective Date, the Party intending to rely thereon has delivered a written notice to the other Party specifying in reasonable detail all breaches of covenants, representations and warranties or other matters which the Party delivering such notice is asserting as the basis for the non-fulfilment or the applicable condition or termination right, as the case may be. If any such notice is delivered, provided that a Party is proceeding diligently to cure such matter and such matter is capable of being cured, no Party may terminate this Agreement until the earlier of : (i) the expiration of a period of five (5) business days from such notice; and (b) the Outside Date.

7.4	Insurance and Indemnification

(a)

Prior to the Effective Date, HSE shall purchase customary “tail” policies of directors’ and officers’ liability insurance providing protection no less favourable in the aggregate to the protection provided by the policies maintained by HSE and its Subsidiaries which are in effect immediately prior to the Effective Date and providing protection in respect of claims arising from facts or events which occurred on or prior to the Effective Date and DXP and Acquiror will, or will cause HSE and its Subsidiaries to, maintain such tail policies in effect without any reduction in scope or coverage for six (6) years from the Effective Date; provided, that neither DXP nor Acquiror shall be required to pay any amounts in respect of such coverage prior to the Effective Time and provided, further that the cost of such policy shall not exceed 200% of HSE’s current annual aggregate premium for policies currently maintained by HSE or its Subsidiaries.

(b)

DXP and Acquiror agree that they shall directly honour all rights to indemnification or exculpation now existing in favour of present and former officers and directors of HSE and its Subsidiaries to the extent that they are disclosed in Schedule 7.4(b) of the HSE Disclosure Letter, and acknowledge that such rights, to the extent that they are disclosed in Schedule 7.4(b) of the HSE Disclosure Letter, shall survive the completion of the Plan of Arrangement and shall continue in full force and effect for a period of not less than six (6) years from the Effective Date.

(c)

The provisions of this Section 7.4 are intended for the benefit of, and shall be enforceable by, each insured or indemnified Person, his or her heirs and his or her legal representatives and, for such purpose, HSE hereby confirms that it is acting as agent and trustee on their behalf. Furthermore, this Section 7.4 shall survive the termination of this Agreement as a result of the occurrence of the Effective Date for a period of six (6) years.

For greater certainty, each Party agrees that, upon any termination of this Agreement under circumstances where HSE or Acquiror is entitled to a Fee and such Fee is paid in full, HSE or Acquiror, as the case may be, shall be precluded from any other remedy against the other Party at Law or in equity or otherwise (including, without limitation, an order for specific performance), and shall not seek to obtain any recovery, judgment, or damages of any kind, including consequential, indirect, or punitive damages, against the other Party or any of its Subsidiaries or any of their respective directors, officers, employees, partners, managers, members, shareholders or affiliates or their respective representatives in connection with this Agreement or the transactions contemplated hereby, provided, however that payment by a Party of a Fee shall not be in lieu of any damages or any other payment or remedy available in the event of any wilful or intentional breach by such Party of any of its obligations under this Agreement.

9.3	Governing Law; Waiver of Jury Trial

This Agreement shall be governed, including as to validity, interpretation and effect, by the Laws of the Province of Alberta and the Laws of Canada applicable therein. Each of the Parties hereby irrevocably attorns to the exclusive jurisdiction of the courts of the Province of Alberta in respect of all matters arising under and in relation to this Agreement and the Arrangement and waives any defences to the maintenance of an action in the Courts of the Province of Alberta. EACH PARTY TO THIS AGREEMENT HEREBY WAIVES ANY RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF THE PARTIES IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT.

9.4	Injunctive Relief

Subject to Section 8.3, the Parties agree that irreparable harm would occur for which money damages would not be an adequate remedy at Law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Accordingly, the Parties agree that, in the event of any breach or threatened breach of this Agreement by a Party, the non-breaching Party will be entitled, without the requirement of posting a bond or other security, to equitable relief, including injunctive relief and specific performance, and the Parties shall not object to the granting of injunctive or other equitable relief on the basis that there exists an adequate remedy at Law. Subject to Section 8.3, such remedies will not be the exclusive remedies for any breach of this Agreement but will be in addition to all other remedies available at Law or equity to each of the Parties. Notwithstanding the foregoing or any other provision of this Agreement, the Parties acknowledge and agree that HSE shall not be entitled to enforce specifically the obligations of DXP and Acquiror to consummate the transactions contemplated by this Agreement unless all of the conditions set forth in Section 6.1 and Section 6.2 shall have been satisfied or waived.

9.5	Time of Essence

Time shall be of the essence in this Agreement.

9.6	Entire Agreement, Binding Effect and Assignment

This Agreement (including the exhibits and schedules hereto and the HSE Disclosure Letter) and the HSE Confidentiality Agreement constitute the entire agreement, and supersede all other prior agreements and understandings, both written and oral, between the Parties, or any of them, with respect to the subject matter hereof and thereof and, except as expressly provided herein, this Agreement is not intended to and shall not confer upon any Person other than the Parties any rights or remedies hereunder. Neither this Agreement nor any of the rights, interests or obligations hereunder may be assigned by either of the Parties without the prior written consent of the other Parties.

9.7	No Liability

Absent fraud, no director or officer of DXP or Acquiror shall have any personal liability whatsoever to HSE under this Agreement, or any other document delivered in connection with the transactions contemplated hereby on behalf of DXP or Acquiror. Absent fraud, no director or officer of HSE shall have any personal liability whatsoever to DXP or Acquiror under this Agreement, or any other document delivered in connection with the transactions contemplated hereby on behalf of HSE.

9.8	Severability

If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule or Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.

9.9	Counterparts, Execution

This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original but all of which together shall constitute one and the same instrument. The Parties shall be entitled to rely upon delivery of an executed facsimile or similar executed electronic copy of this Agreement, and such facsimile or similar executed electronic copy shall be legally effective to create a valid and binding agreement between the Parties.
