STOCK PURCHASE AGREEMENT

This Stock Purchase Agreement (“Agreement”) is entered into on this 27th day of April, 2010 by and among Mesa Laboratories, Inc., a Colorado corporation (“Buyer”), and each of Darlene Hartze and John R. Gillis (each a “Seller” and collectively, “Sellers”), the sole shareholders of SGM Biotech, Inc., a Montana corporation (“SGM”).  Buyer and Sellers are collectively referred to herein as the “Parties.”

BACKGROUND

A.  SGM is engaged in the business of (i) conducting research and development relating to bacterial spores and sterilization processes and (ii) developing, manufacturing and selling or distributing biological indicators (collectively, the “Business”).

B.  Sellers collectively own all of the issued and outstanding capital stock of SGM (“SGM Shares”).

C.  Sellers desire to sell to Buyer, and Buyer desires to purchase from Sellers, the SGM Shares, in each case in accordance with the terms and conditions of this Agreement.

NOW, THEREFORE, in consideration of the premises and the mutual promises, covenants and agreements herein made, and in consideration of the representations, warranties, and covenants herein contained, the Parties agree as follows:

Definitions.  Defined terms herein shall have the meanings ascribed to them in Exhibit A.

Purchase and Sale of SGM Shares; Purchase Price; Closing.

Basic Transaction.  On and subject to the terms and conditions of this Agreement, Buyer hereby purchases from Sellers, and Sellers hereby sell to Buyer, all right, title and interest of Sellers in and to the SGM Shares free and clear of all Liens.

Purchase Price.  The aggregate purchase price for the SGM Shares shall be an amount equal to Eleven Million Seven Hundred Twenty-Two Thousand Thirteen and 44/100 Dollars ($11,722,013.44), (“Closing Purchase Price”), as such amount shall be increased or decreased on a dollar for dollar basis by the Final Working Capital Adjustment Amount pursuant to Section 2(d) below.  All payments pursuant to this Section 2(b) shall be collectively referred to herein as the “Purchase Price.”

Payment of Closing Purchase Price.  The Closing Purchase Price shall be paid at the Closing as follows, in each case by wire transfer of immediately available funds to an account designated by the recipient prior to the Closing:

1

Six Hundred Thousand and No/100 Dollars ($600,000.00) (“Escrow Amount”) shall be deposited by Buyer into a joint escrow account pursuant to the terms of the Escrow Agreement and shall be disbursed by the Escrow Agent in accordance with the terms of the Escrow Agreement, which Escrow Agreement shall provide that all escrow fees shall be paid by Buyer;

Buyer shall deliver to Sellers an amount equal to Eleven Million One Hundred Twenty-Two Thousand Thirteen and 44/100 Dollars ($11,122,013.44).  The aggregate amount of payment contemplated by this Section 2(c)(ii) shall be paid to each Seller in proportion to their respective holdings of SGM Shares, one-half (1/2) each.

Working Capital Adjustments.  The Purchase Price shall be increased or decreased on a dollar for dollar basis, in accordance with this Section 2(d).  The Parties hereby jointly designate the “Target Working Capital Amount” as the Working Capital (defined in Exhibit A) of SGM as of December 31, 2009, as determined by an audit of the financials as of such date to be conducted by Buyer following the Closing Date.  For purposes of the Agreement, the “Working Capital Adjustment Amount” shall be equal to the audited Working Capital as of the Closing Date (the “Closing Date Working Capital”) minus the Target Working Capital Amount, each of which shall be calculated in the same manner.  For the purposes of calculating and determining the Working Capital, all calculations shall include any deposits, or accruals for the Sterifast bier vessel, but shall exclude (i) all cash, (ii) any accrued or paid buy/sell professional fees, and (iii) the SGM Related Party Debt, each of items (ii) and (iii) above to be paid in full by SGM and/or the Sellers at or prior to Closing.

Preliminary Working Capital Adjustment Amount.  Within seventy-five (75) days after the Closing Date, Buyer shall prepare and deliver, or cause to be prepared and delivered, to Sellers (a) the Target Working Capital Amount, (b) the Closing Date Working Capital, (c) a statement setting forth the Buyer’s preliminary Working Capital Adjustment Amount (the “Preliminary Closing Statement”) and (d) any and all supporting documentation relating to each of the above calculations, including, but not limited to, all work papers relating to such calculations.

Sellers’ Review.  Sellers will have thirty (30) days following receipt of the Target Working Capital Amount, the Closing Date Working Capital Amount and the Preliminary Closing Statement to determine, in good faith, if the Target Working Capital Amount, the Closing Date Working Capital Amount and/or the Preliminary Closing Statement have been calculated in accordance with the terms of this Section 2(d) and each is true, accurate and complete.  If Sellers determine that the Target Working Capital Amount, the Closing Date Working Capital Amount and/or the Preliminary Closing Statement have any discrepancies or are otherwise incorrect, inconsistent, inaccurate or not determined and/or calculated in accordance with the terms of this Section 2(d) or are not otherwise true, accurate and complete, Sellers shall notify Buyer in writing of Sellers’ proposed adjustments to any of the Target Working Capital Amount, the Closing Date Working Capital Amount and the Preliminary Closing Statement on or before the end of such thirty (30)day period, including reasonable detail of the nature and basis for the adjustments and all work papers related thereto (collectively, the “Working Capital Objection”).

2

Dispute.  If Sellers deliver a Working Capital Objection, then within fifteen (15) days following receipt by Buyer of such Working Capital Objection, the Parties shall confer and negotiate in good faith to resolve the matters in dispute as set forth in the Working Capital Objection.  If the Parties cannot mutually resolve any such disputes within such fifteen (15) day period, either Party shall have the right at any time thereafter to cause the Parties to jointly engage the independent accounting firm of PricewaterhouseCoopers, 1670 Broadway, Suite 1000, Denver, Colorado 80202, subject to such firm’s confirmation that it is independent of both Parties at the time of any such engagement.  In the event that the Independent Accountant is not independent at the time of such engagement, the Parties agree to select, within the fifteen (15) day period following Buyer’s receipt of the Working Capital Objection, one firm by lot from the “Big 4” accounting firms, excluding any other nationally recognized accounting firm that is not independent (such selected firm, the “Independent Accountant”).  The Parties jointly shall engage the Independent Accountant, acting as an expert and not an arbiter, to review only those items in dispute by the Parties.  The Independent Accountant shall be furnished with a copy of this Agreement, the Target Working Capital Amount, the Closing Date Working Capital Amount, the Preliminary Closing Statement and the Working Capital Objection, and any other documentation of either Party that the Independent Accountant determines to be necessary and relevant to resolving such disputes.  The Independent Accountant shall, within thirty (30) days following the commencement of its engagement by the Parties, complete its review and render a written report setting forth its conclusion as to calculation of the Target Working Capital Amount, the Closing Date Working Capital Amount and the Working Capital Adjustment Amount.  The decision by the Independent Accountant shall be in writing and delivered to the Parties.  The Parties agree that the Independent Accountant is the exclusive Person to make all interpretations necessary (including interpretations or constructions of this Agreement) to support its determinations.  The Independent Accountant’s decision shall be the final Working Capital Adjustment Amount (“Final Working Capital Adjustment Amount”) and shall be final, conclusive and binding upon the Parties and may be entered and enforced in any court of competent jurisdiction.  The Parties agree to submit to the jurisdiction of any such court for the enforcement of such award or decision.  The fees, costs and expenses of the Independent Accountant shall be apportioned between Buyer, on the one hand, and Sellers, on the other, each paying fifty percent (50%) of such fees, costs and expenses of the Independent Accountant.

Final Working Capital Adjustment Amount.  If Sellers do not submit a Working Capital Objection within the thirty (30) day period contemplated by Section 2(d)(ii) above, the Working Capital reflected in the Preliminary Closing Statement will be deemed the Final Working Capital Adjustment Amount.  If the Preliminary Closing Statement is modified by either: (A) mutual agreement by Sellers and Buyer or (B) the Independent Accountant, as the case may be and as provided for above in Section 2(d)(iii), then such modified Preliminary Closing Statement shall be the Final Working Capital Adjustment Amount.

Payment.  Within ten (10) days after the final determination of the Final Working Capital Adjustment Amount pursuant to this Section 2(d), either (A) Sellers shall pay to Buyer the amount, if any, by which the Final Working Capital Amount is less than the Target Working Capital Amount or (B) Buyer shall pay to Sellers the amount, if any, by which the Final Working Capital Adjustment Amount exceeds the Target Working Capital Amount.  Any payment due

3

under this Section 2(d)(v) shall be made by wire transfer of immediately available funds to an account(s) designated by the recipient(s) of such payment at least five (5) days prior to the date of such payment.  If all or any portion of a payment due from Sellers is not paid within such ten (10) day period, then Buyer shall, at its option, be entitled to require that the Escrow Agent pay any such unpaid amount to Buyer from the Escrow Funds and Sellers agree to instruct the Escrow Agent accordingly.  Any remaining unpaid amounts shall remain as the joint and several liability of both Sellers.

Excluded Assets.  Sellers shall cause SGM to distribute the following assets prior to Closing:

The specific assets identified on Schedule 2(e) of the Disclosure Schedule;

All claims and counterclaims against any third party which SGM may have and for which Buyer seeks indemnification from Sellers;

All rights of Sellers under this Agreement and the other documents executed in conjunction with the transactions contemplated by this Agreement to which Sellers are a party; and

All Tax refunds, and all of SGM’s right to receive any such refund, related to any tax period closed prior to the year of the Closing Date.

Closing.  The closing of the transactions contemplated by this Agreement (the “Closing”) shall take place via facsimile, electronic transmission, commencing at 9:00 a.m. Mountain Daylight Time on the date hereof or such other date as Buyer and Sellers may mutually determine, to be effective as of 12:01 a.m. on such date of Closing (the “Closing Date”).

Release of Escrow Amount.  The Parties shall provide to the Escrow Agent joint written instructions to release the Escrow Amount to the Sellers, one-half (1/2) to each Seller, on the dates and in the amounts as follows: (i) Two Hundred Thousand and no/100 Dollars ($200,000.00) at the end of the three (3) month period following the Closing Date, (ii) Two Hundred Thousand and no/100 Dollars ($200,000.00) at the end of the six (6) month period following the Closing Date, and (iii) the balance of the Escrow Funds (including all accrued interest) on the first (1st) anniversary date of the Closing Date.  Notwithstanding the foregoing, if at the date of any scheduled release of the Escrow Amount there is an outstanding unresolved claim for indemnification by Buyer against Sellers pursuant to the terms of this Agreement and if the amount of the pending claim would exceed the Escrow Amount remaining with the Escrow Agent following such release, the Escrow Amount to be released shall be reduced to maintain an Escrow Amount sufficient to satisfy the potential claim outstanding if such claim were resolved in favor of the Buyer and against Sellers.

Sellers each acknowledge and agree that the provisions of this Section 5(d) are a material inducement to Buyer to consummate the transactions contemplated by this Agreement and that the restrictions contained in this Section 5(d) are necessary for the protection of the Business and goodwill of SGM and are considered by Sellers to be reasonable for such purpose.  Sellers each agree that any breach of this Section 5(d) may cause SGM and Buyer substantial and irrevocable damage which may be difficult to measure.  Therefore, in the event of any such breach or threatened breach, Sellers each agree that Buyer and/or SGM, in addition to such other remedies which may be available, shall have the right to obtain an injunction from a court restraining such a breach or threatened breach, and the right to specific performance of the provisions of this Section 5(d).

the representations and warranties of Sellers contained in this Agreement and the Transaction Documents will survive the Closing Date and will continue in full force and effect for a period of one (1) year from the Closing Date (“Cut Off Date”), except for claims for which written notice has been provided in accordance with this Section 7 and that are pending as of the Cut Off Date; provided, however, that the representations and warranties contained in Section 3(a)(iv) (SGM Shares),  Section 4(j) (Tax Matters), Section 4(u) (Employee Benefits) and Section 4(w) (Environmental Matters) shall survive for a period of five (5) years from the Closing Date (the later representations and warranties are collectively referred to as the “Critical Representations”).

Indemnification by Sellers.  Subject to this Section 7, Sellers shall, each up to fifty percent (50%), indemnify and hold harmless Buyer, SGM, and their respective directors and officers (collectively the “Buyer Group”), from and against any Adverse Consequences incurred by the Buyer Group based upon, arising from or relating to (i) any breach of a representation or warranty of Sellers contained in this Agreement, and (ii) any breach of any covenant or obligation of Sellers contained in this Agreement.  For purposes of determining the amount of any Adverse Consequences incurred by any member of the Buyer Group, but not for purposes of determining a breach of any representation, warranty or covenant of Sellers contained in this Agreement or the Transaction Documents, “materiality,” “Material Adverse Effect” and other similar qualifications shall be disregarded.

Indemnification by Buyer.  Buyer shall indemnify and hold Sellers, and their respective estates, heirs and personal representatives, harmless from and against any Adverse Consequences incurred by them based upon, arising from or relating to any (i) breach of a representation or warranty of Buyer contained in this Agreement, and (ii) breach of any covenant or obligation of Buyer contained in this Agreement.

Procedures.

As soon as reasonably practicable after an indemnitee (a “Claimant”) has actual knowledge of any claim that it has under this Section 7 that could reasonably be expected to result in Adverse Consequences for which Claimant is entitled to indemnification under this Section 7 (“Indemnifiable Claim”), the Claimant shall promptly notify the Party responsible for indemnification (“Indemnifying Party”) in writing, pursuant to the Notice provision set forth in Section 9(g), of such Indemnifiable Claim (a “Claims Notice”).  No delay in or failure to give notice of an Indemnifiable Claim will adversely affect any of the other rights or remedies that the Claimant has under this Agreement or alter or relieve an Indemnifying Party of its obligation to indemnify the Claimant except to the extent that an Indemnifying Party is prejudiced thereby.

Subject to the provisions of this Section 7, generally, in the event of a non-third party claim against a Claimant for which indemnification is available hereunder, the Indemnifying Party shall respond to the Claimant (a “Claim Response”) within forty-five (45) days (the “Response Period”) after the date that the Claims Notice is given by the Claimant.  Any Claim Response must specify whether or not the Indemnifying Party disputes the claim described in the Claims Notice or if additional information is required.  If the Indemnifying Party fails to give a

25

Claim Response within the Response Period, the Indemnifying Party will be deemed not to dispute the claim described in the related Claims Notice.  If the Indemnifying Party elects not to dispute a claim described in a Claims Notice, whether by failing to give a timely Claim Response or otherwise, then the amount of Adverse Consequences alleged in such Claims Notice will be conclusively deemed to be an obligation of the Indemnifying Party, and the Indemnifying Party shall satisfy such obligation within fifteen (15) days after the last day of the applicable Response Period in the amount specified in the Claims Notice.  If the Indemnifying Party delivers a Claim Response within the Response Period indicating that it disputes one or more of the matters identified in the Claims Notice or requests additional information, a representative of Buyer and Sellers shall promptly meet and use their reasonable efforts to settle the dispute.  Buyer, SGM and Sellers shall cooperate with and make available to the other Party and their respective representatives all information, records and data, and shall permit reasonable access to its facilities and personnel, as may be reasonably required in connection with the resolution of such disputes.  If Buyer’s representative and Sellers are unable to reach agreement within thirty (30) days after the conclusion of the Response Period, then either Buyer or Sellers may resort to other legal remedies subject to the limitations set forth in this Section 7.  If Buyer and Sellers are able to reach an agreement during the term of the Escrow Account with respect to the Indemnifiable Claim at issue, resulting in Sellers owing money to Buyer, then Buyer and Sellers shall promptly execute and deliver joint written instructions instructing the Escrow Agent to release an amount from the Escrow Funds equal to (i) the agreed upon or finally determined amount of any claim in which any of the Buyer Group is the Claimant, which shall be released to Buyer and (ii) an amount equal to the excess (if any) of the remaining Escrow Funds over the aggregate amount of all claims identified in a Claims Notice (if any) that have not been agreed upon or finally determined on or prior to the Cut Off Date, which shall be released to Sellers, in each case accordance with the terms of such joint instruction and the terms of the Escrow Agreement.

Subject to the provisions of this Section 7 generally, in the event of a claim by a third party against a Claimant for which indemnification is available hereunder (a “Third Party Claim”), the Indemnifying Party shall have the right, exercisable by delivery of written notice to the Claimant, to assume and direct the defense against, negotiate, settle or otherwise deal with (including the employment of counsel) any such Third Party Claim, and all fees, costs and expenses incurred by the Indemnifying Party or at its request, in connection with defending or settling such Third Party Claim by the Indemnifying Party shall be borne solely by the Indemnifying Party (subject to the limitations set forth in this Section 7) and any costs or expenses incurred on by or on behalf of the Claimant or at its request shall be borne solely by the Claimant; provided, however, that the Indemnifying Party shall not settle or compromise any such Third Party Claim or permit a default or consent to entry of any judgment without the prior written consent of the Claimant, which consent shall not be unreasonably withheld or delayed, provided, however, such consent shall not be required, if such settlement, compromise or consent: (1) requires only the payment of money damages and contains an unconditional release of the Claimant and its officers, directors, employees and Affiliates from all Liability arising out of such Third Party Claim, (2) does not contain any admission or statement suggesting any wrongdoing or liability on behalf of the Claimant, and (3) the Indemnifying Party agrees in writing that the entire amount of such proposed settlement constitutes Adverse Consequences for which the Indemnifying Party is responsible and that the Indemnifying Party shall satisfy such

26

Adverse Consequences in full, subject to the limitations contained in this Section 7.  If the Indemnifying Party elects to defend against, negotiate, settle or otherwise deal with such Third Party Claim, it shall, within ten (10) business days, notify the Claimant of its intent to do so and the Claimant agrees to cooperate fully with the Indemnifying Party and its counsel in the settlement, compromise of, or defense against, any such asserted Liability; provided, however, so long as the Indemnifying Party is actively and diligently pursuing the defense, negotiation settlement or otherwise dealing with the Third Party Claim, the Indemnifying Party shall not be liable or responsible for the costs and expenses of the Claimant, including, but not limited to, the Claimant’s attorneys’ fees.

Notwithstanding an election by the Indemnifying Party to assume the defense of a Third Party Claim, the Claimant shall have the right, at its sole cost and expense, to employ separate counsel to monitor the defense of such claim; provided, however, neither the Claimant nor its counsel shall have any direct contact with such third party claimant or attempt to settle, compromise or otherwise attempt to resolve such Third Party Claim without the consent and participation of the Indemnifying Party.

The Claimant shall cooperate in all reasonable respects with the Indemnifying Party and such attorneys in the investigation, discovery, trial and defense of a Third Party Claim and any appeal arising therefrom.  All reasonable third party costs and expenses incurred in connection with a Claimant’s cooperation, as requested by the Indemnifying Party in writing, shall be borne by the Indemnifying Party, subject to the limitations set forth in this Section 7.

To the extent the Claimant is Buyer and Buyer seeks indemnification, pursuant to this Section 7, from either or both Sellers, the Parties hereby agree that all rights, claims and counterclaims against any third party (other than the Buyer) which SGM may have shall be available to Sellers as the Indemnifying Party in connection with such Claim.

Limitations.  An Indemnifying Party shall not have any liability under Section 7 unless the aggregate amount of Adverse Consequences incurred by the Claimant (with no minimum amount for each claim) thereunder exceeds One Hundred Fifty Thousand and No/100 Dollars ($150,000.00) (the “Basket”) and, in such event,  the Indemnifying Party shall be required to pay the amount of all such Adverse Consequences up to a maximum amount of the Purchase Price (“Cap”).  The Claimant’s right to indemnification pursuant to Section 7 on account of any Adverse Consequences will be reduced by all insurance proceeds actually received by the Claimant.

Exclusive Remedy.  Buyer and Sellers acknowledge and agree that the exclusive remedies of Sellers and Buyer for any Adverse Consequences based upon, arising out of or otherwise in respect of the matters set forth in this Agreement are the indemnification obligations of the parties set forth in this Section 7.  The provisions of this Section 7(f) shall not, however, prevent or limit a cause of action under Section 7(g) to obtain an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof.

27

Specific Performance.  Each Party’s obligation under this Agreement is unique.  If any Party should breach its covenants under this Agreement, the Parties each acknowledge that it would be extremely impracticable to measure the resulting damages; accordingly, the non breaching Party or Parties, in addition to any other available rights or remedies they may have under the terms of this Agreement, may sue in equity for specific performance, and each party expressly waives the defense that a remedy in damages will be adequate.

Tax Matters.  The following provisions shall govern the allocation of responsibility as between Buyer and Sellers for certain Tax matters following the Closing Date:

Tax Indemnification.

To the extent not otherwise accrued for in the Final Working Capital Amount, Sellers shall indemnify SGM and hold SGM harmless from and against any Adverse Consequences attributable to (i) all Taxes (or the non-payment thereof) of SGM for all taxable periods ending on or before the Closing Date and the portion through the end of the Closing Date for any taxable period that includes (but does not end on) the Closing Date (“Pre-Closing Tax Period”), (ii) all Taxes of any member of an affiliated, consolidated, combined or unitary group of which SGM (or any predecessor or current or former affiliate of any of the foregoing) is or was a member on or prior to the Closing Date, including pursuant to Treasury Regulation Section 1.1502-6 (or any analogous provision of state, local or foreign Tax Law), and (iii) any and all Straddle Period Taxes allocable to Sellers for the Pre-Closing Tax Period.  Sellers shall reimburse SGM for any Taxes that are the responsibility of Sellers pursuant to this Section 8 within fifteen (15) business days after payment of such Taxes by Buyer, an Affiliate of Buyer or SGM.

Buyer shall indemnify each Seller and hold them harmless from and against any Adverse Consequences attributable to (i) all Taxes (or the non-payment thereof) of SGM for all taxable periods ending after the Closing Date for any taxable period that is on or after the Closing Date (“Post-Closing Tax Period”), (ii) all Taxes of any member of an affiliated, consolidated, combined or unitary group of which SGM (or any current or former affiliate of any of the foregoing) is or becomes a member after the Closing Date, including pursuant to Treasury Regulation Section 1.1502-6 (or any analogous provision of state, local or foreign Tax Law), (iii) any and all Taxes of any Person (other than SGM) imposed on SGM as a transferee or successor, by contract or pursuant to any Law, which Taxes relate to an event or transaction occurring after the Closing, (iv) any Taxes related to or as a result of the transactions contemplated hereby, (v) any Taxes related to or as a result of any elections made by SGM, Buyer or an affiliate of Buyer after the Closing even if such Taxes are attributable to a Pre-Closing Tax Period, (vi) any and all Straddle Period Taxes allocable to Buyer for the Post-Closing Tax Period, and (vii) all Taxes for Pre-Closing Tax Period accrued for in the Final Working Capital Amount.  Buyer shall reimburse Sellers for any Taxes that are the responsibility of Buyer pursuant to this Section 8 within fifteen (15) business days after payment of such Taxes by Sellers.

Straddle Period.  In the case of any taxable period that includes (but does not end on) the Closing Date (a “Straddle Period”), the amount of any Taxes based on or measured by income or receipts of SGM for the Pre-Closing Tax Period or the Post-Closing Tax Period,

28

as the case may be, shall be determined based on an interim closing of the books as of the close of business on the Closing Date and the amount of other Taxes of SGM for a Straddle Period that relates to the Pre-Closing Tax Period or the Post-Closing Tax Period, as the case may be, shall be deemed to be the amount of such Tax for the entire taxable period multiplied by a fraction, the numerator of which is the number of days in the taxable period ending on or after the Closing Date, as the case may be, and the denominator of which is the number of days in such Straddle Period.

Responsibility for Filing Tax Returns.  Buyer shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for SGM that are to be filed as of and after the Closing Date in accordance with applicable Tax Law; provided, however, Buyer shall permit Sellers the right to review and comment on each such Tax Return relating to a Pre-Closing Tax Period or such other return which may result in an increase in Taxes for a Pre-Closing Tax Period and Buyer shall make such revisions to such Tax Returns as are reasonably requested by Sellers.

Refunds and Tax Benefits.  Any Tax refunds that are received by Buyer or SGM, and any amounts credited against any Tax to which Buyer or SGM become entitled, that relate to any Pre-Closing Tax Period shall be for the account and benefit of Sellers, and Buyer shall pay over to Sellers any such refund or the amount of any such credit within fifteen (15) days after receipt or final confirmation of entitlement thereto.

Cooperation on Tax Matters.

Buyer, SGM and Sellers shall cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the filing of Tax Returns pursuant to this Section 8 and any audit, litigation or other proceeding with respect to Taxes relating to a period of time prior to the Closing Date.  Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information that are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.  SGM agrees (A) to retain all books and records with respect to Tax matters pertinent to SGM relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by Buyer or Sellers, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (B) to give the other Party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other Party so requests, SGM or Sellers, as the case may be, shall allow the other Party to take possession of such books and records.

Buyer and Sellers further agree, upon request, to use their best efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby).

29

Certain Taxes and Fees.  All transfer, documentary, sales, use, stamp, registration and other such Taxes, and all conveyance fees, recording charges and other fees and charges (including any penalties and interest) incurred in connection with the consummation of the transactions contemplated by this Agreement shall be borne by Buyer.

Miscellaneous.

Press Releases and Public Announcements.  No Party shall issue any press release or make any public announcement relating to the subject matter of this Agreement prior to the Closing, without the prior written approval of Buyer and Sellers; provided, however, that any Party may make any public disclosure it believes in good faith is required by applicable Law or any listing or trading agreement concerning its publicly traded securities (in which case the disclosing Party will use commercially reasonable efforts to advise the other Parties prior to making the disclosure).

No Third Party Beneficiaries.  This Agreement shall not confer any rights or remedies upon any Person other than the Parties and their respective successors and permitted assigns.

Entire Agreement.  This Agreement and the Transaction Documents, including the Exhibits and Disclosure Schedule hereto, constitute the entire agreement among the Parties and supersede any prior understandings, agreements, or representations by or among the Parties, written or oral, to the extent they relate in any way to the subject matter hereof.

Succession and Assignment.  This Agreement shall be binding upon and inure to the benefit of the Parties named herein and their respective successors and permitted assigns.  No Party may assign either this Agreement or any of his, her, or its rights, interests, or obligations hereunder without the prior written approval of Buyer and Sellers; provided, however, that Buyer may (i) assign any or all of its rights and interests hereunder to one or more of its Affiliates and (ii) designate one or more of its Affiliates to perform its obligations hereunder (in any or all of which cases Buyer nonetheless shall remain responsible for the performance of all of its obligations hereunder).

Counterparts.  This Agreement may be executed in one or more counterparts, including by means of facsimile or electronic mail, each of which shall be deemed an original but all of which together will constitute one and the same instrument.

Headings.  The section headings contained in this Agreement are inserted for convenience only and shall not affect in any way the meaning or interpretation of this Agreement.

Notices.  All notices, requests, demands, claims, and other communications hereunder shall be in writing.  Any notice, request, demand, claim, or other communication hereunder shall be deemed duly given (i) when delivered personally to the recipient, (ii) one (1) business day after being sent to the recipient by reputable overnight courier service (charges prepaid), (iii) one (1) business day after being sent to the recipient by confirmed facsimile transmission or electronic mail, or (iv) four (4) business days after being mailed to the

Any Party may change the address to which notices, requests, demands, claims, and other communications hereunder are to be delivered by giving the other Parties notice in the manner herein set forth.

Governing Law.  This Agreement shall be governed by and construed in accordance with the domestic laws of the State of Colorado without giving effect to any choice or conflict of law provision or rule that would cause the application of the laws of any jurisdiction other than the State of Colorado.

Amendments and Waivers.  No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed by Buyer and Sellers.  No waiver by any Party of any provision of this Agreement, or any waiver of any default, misrepresentation or breach of warranty or covenant hereunder, whether intentional or not, shall be valid unless the same shall be in writing and signed by the Party making such waiver nor shall such waiver be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence.

Severability.  Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending

31

term or provision in any other situation or in any other jurisdiction.  If any provision of this Agreement is so broad as to be unenforceable, the provisions will be interpreted to be only so broad as is enforceable.

Construction.  The Parties have participated jointly in the negotiation and drafting of this Agreement.  In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement.  Any reference to any federal, state, local, or non U.S. statute or law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise.  The word “including” shall mean including without limitation.

Incorporation of Exhibits and Schedules.  The Exhibits and Schedules identified in this Agreement are incorporated herein by reference and made a part hereof.

Attorney-Client Privilege.  Buyer, for itself and on behalf of SGM following the Closing, acknowledges that Buyer and SGM have no rights as clients to assert any claim of access, confidentiality and/or privilege with respect to communications and work product generated by Minor & Brown, P.C., in connection with their representation of SGM and Sellers in connection with this Agreement, the Transaction Documents and the transactions contemplated hereby.  SGM and Buyer hereby waive any conflict of interest that may apply in the further representation of Sellers in connection with any disputes arising from this Agreement, Transaction Documents and the transactions contemplated hereby or in connection with any other matters.  Notwithstanding the foregoing, SGM and Buyer further acknowledge and agree that Sellers shall maintain all client rights (including confidentiality and privilege) with respect to the prior representation of SGM and Sellers by Minor & Brown, P.C.’s, in connection with the possible sale of SGM.

Tax Disclosure Authorization.  Notwithstanding anything herein to the contrary, the Parties (and each Affiliate and Person acting on behalf of any Party) agree that each Party (and each employee, representative, and other agent of such Party) may disclose to any and all Persons, without limitation of any kind, the transaction’s tax treatment and tax structure (as such terms are used in regulations promulgated under Code §6011) contemplated by this Agreement and all materials of any kind (including opinions or other tax analyses) provided to such Party or such Person relating to such tax treatment and tax structure, except to the extent the disclosure of such information is restricted to comply with any applicable federal or state securities laws; provided, however, that such disclosure may not be made until the earliest of the date of (A) public announcement of discussions relating to the transaction, (B) public announcement of the transaction, or (C) execution of an agreement (with or without conditions) to enter into the transaction. This authorization is not intended to permit disclosure of any other information, including (without limitation) (V) any portion of any materials to the extent not related to the transaction’s tax treatment or tax structure, (W) the identities of participants or potential participants, (X) the existence or status of any negotiations, (Y) any pricing or financial information (except to the extent such pricing or financial information is related to the transaction’s tax treatment

32

or tax structure), or (Z) any other term or detail not relevant to the transaction’s tax treatment or the tax structure.

(o) Investigation.  The representations, warranties, covenants and agreements set forth in this Agreement shall not be affected or diminished in any way by any investigation (or failure to investigate) at any time by or on behalf of the Party for whose benefit such representations, warranties, covenants and agreements were made.

(p)  Other Remedies; Injunctive Relief.  Except as otherwise provided herein, any and all remedies herein expressly conferred upon a Party will be deemed cumulative with and not exclusive of any other remedy conferred hereby upon such Party, and the exercise by a Party of any one remedy hereunder will not preclude the exercise of any other remedy hereby.  The Parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached.  It is accordingly agreed that the Parties shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any federal or state court sitting in the State of Colorado, this being in addition to any other remedy to which they are entitled at law or in equity.  In any action at law or suit in equity to enforce this Agreement or the rights of the Parties hereunder, the prevailing party in any such action or suit shall be entitled to receive a reasonable sum for its attorneys’ fees and all other reasonable costs and expenses incurred in such action or suit.

(q)  Remedies Exclusive.  Except (i) pursuant to the provisions of the Escrow Agreement and (ii) in the case of fraud or equitable remedies expressly provided for herein, the Parties acknowledge and agree that the indemnification provisions set forth in this Agreement constitute the Parties’ sole and exclusive remedy with respect to any and all claims relating to the transactions contemplated by this Agreement.

(r)  Jurisdiction and Venue.  This Agreement shall be subject to the exclusive jurisdiction of the courts of the State of Colorado.  The parties to this Agreement agree that any breach of any term or condition of this Agreement shall be deemed to be a breach occurring in the State of Colorado by virtue of a failure to perform an act required to be performed in the State of Colorado and irrevocably and expressly agree to submit to the exclusive jurisdiction of the courts of the State of Colorado for the purpose of resolving any disputes among the Parties relating to this Agreement or the transactions contemplated hereby.  The Parties irrevocably waive, to the fullest extent permitted by law, any objection which they may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement, or any judgment entered by any court in respect hereof brought in the State of Colorado, and further irrevocably waive any claim that any suit, action or proceeding brought in the State of Colorado has been brought in an inconvenient forum.
