The Lender agrees promptly to notify the Borrower after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Lender under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) that the Lender may have. ARTICLE 7 CONDITIONS OF LENDING The obligation of the Lender to make the Loan is subject to the conditions precedent stated in this Article 7 wherein each document to be delivered to the Lender shall be in form and substance satisfactory to it. Section 7.01 Closing.

In consideration of the Lender's willingness to close the Loan without such satisfaction, the Borrower covenants and agrees that the Borrower shall satisfy all of such conditions precedent required pursuant to Section 7.02 but not satisfied prior to or at the Closing as soon as possible following the Closing, but in any event no later than fifteen (15) Business Days thereafter, except that consummation of the Private Placement referenced in Section 7.02(e) must occur in any event no later than thirty (30) Business Days thereafter.

BORROWER: FLOTEK INDUSTRIES INC. By: /s/ WILLIAM G. JAYROE ------------------------------------ William G. Jayroe, President and Chief Executive Officer By: /s/ SCOTT COOK ------------------------------------ Name: Scott Cook ---------------------------------- Title: Vice President --------------------------------- LENDER: TOSI, L.P., a Texas limited partnership By: Pitman Property Corp., a Texas Corporation, General Partner By: /s/ J. W. BEAVERS, JR ------------------------------------ J. W. Beavers, Jr., President 23 24 Exhibit 1.01 Form of Promissory Note FORM OF PROMISSORY NOTE October ___, 1997 US$750,000.00 FOR VALUE RECEIVED, FLOTEK INDUSTRIES INC., an Alberta corporation ("Borrower"), promises to pay to the order of TOSI, L.P., a Texas limited partnership ("Lender"), on or before October ___, 1998, at its office at 3900 Thanksgiving Tower, 1601 Elm Street, Dallas, Texas 75201, or at such other location as Lender may designate, in immediately available funds, SEVEN HUNDRED FIFTY THOUSAND AND NO/100 UNITED STATES DOLLARS (US$750,000.00). Borrower will also pay interest on the unpaid principal balance outstanding from time to time at a fixed rate of ten percent (10%) per annum, payable quarterly in arrears. Interest will be computed on the basis of the actual number of days elapsed and a year comprising 360 days, unless such calculation would result in a usurious interest rate, in which case such interest will be calculated on the basis of a 365 or 366 day year, as the case may be. All past due principal and interest on this Note will, at Lender's option, bear interest at the maximum nonusurious rate of interest ("Highest Lawful Rate") or, if applicable law does not provide for a maximum nonusurious rate of interest, at a rate per annum equal to 18%. Borrower covenants to apply the total amount advanced by Lender hereunder only in the manner set forth in that certain Convertible Loan Agreement of even date herewith between Borrower and Lender (the "Loan Agreement"). Borrower understands and acknowledges that Lender would not be willing to make the loan evidenced hereby but for Borrower's covenant set forth in the immediately- preceding sentence. All undefined capitalized terms used in this Note shall have the meanings respectively ascribed to them in the Loan Agreement. In addition to all principal and accrued interest on this Note, Borrower agrees to pay: (a) all reasonable costs and expenses incurred by or on behalf of Lender and all owners and holders of this Note in attempting to collect this Note through probate, reorganization, bankruptcy or any other proceeding; and (b) reasonable attorneys fees if and when this Note is placed in the hands of an attorney for collection. The outstanding principal amount of the Loan evidenced by this Note shall be convertible into common shares of Borrower in the manner and to the extent set forth in the Loan Agreement. Exhibit 1.01-1 25 Borrower and Lender intend to conform strictly to applicable usury laws. Therefore, the total amount of interest (as defined under applicable law) contracted for, charged or collected under this Note will never exceed the Highest Lawful Rate. If Lender contracts for, charges or receives any excess interest, it will be deemed a mistake. Lender will automatically reform the contract or charge to conform to applicable law and, if excess interest has been received, Lender will either refund the excess to Borrower or credit the excess on the unpaid principal amount of this Note. All amounts constituting interest will be spread throughout the full term of this Note in determining whether interest exceeds lawful amounts. The unpaid principal balance of this Note at any time will be the total amount advanced by Lender, less the amount of all payments of principal. Borrower may at any time pay the full amount of this Note without the payment of any premium, penalty or fee. "Loan Document" means this Note and any document or instrument evidencing, securing, guaranteeing or given in connection with this Note including, without limitation, the Loan Agreement, the Warrant and the Registration Rights Agreement. "Obligations" means all principal, interest and other amounts which are or become owing under this Note or any other Loan Document. "Obligor" means Borrower and any guarantor, surety, co-signer, or other person who may now or hereafter be obligated to pay all or any part of the Obligations. Where appropriate, the masculine gender includes the feminine and the neuter and the singular number includes the plural number. Each Obligor severally waives notice, demand, presentment for payment, notice of nonpayment, notice of intent to accelerate, notice of acceleration, protest, notice of protest and the filing of suit and diligence in collecting this Note and all other demands and notices, and consents and agrees that its liabilities and obligations will not be released or discharged by any or all of the following, whether with or without notice to it or any other Obligor, and whether before or after the stated maturity hereof: (i) extensions of the time of payment; (ii) renewals; (iii) acceptances of partial payments; (iv) releases or substitutions of any collateral or any Obligor; and (v) failure, if any, to perfect or maintain perfection of any security interest in any collateral. Each Obligor agrees that acceptance of any partial payment will not constitute a waiver and that waiver of any default will not constitute waiver of any prior or subsequent default. This Note is governed by the laws of the Province of Alberta (exclusive of any such laws that pertain to conflicts of laws). If any provision of this Note is illegal or unenforceable, that illegality or unenforceability will not affect the remaining provisions of this Note. BORROWER(S) AND LENDER AGREE THAT THIS NOTE WILL BE PERFORMED IN DALLAS COUNTY, TEXAS, AND THAT SUCH COUNTY IS PROPER VENUE FOR ANY ACTION OR PROCEEDING BROUGHT BY BORROWER(S) OR LENDER, WHETHER IN CONTRACT, TORT, OR OTHERWISE. ANY ACTION OR PROCEEDING AGAINST BORROWER(S) MAY BE BROUGHT IN ANY STATE OR FEDERAL COURT IN SUCH COUNTY TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW. TO THE EXTENT PERMITTED BY APPLICABLE LAW, BORROWER(S) HEREBY IRREVOCABLY (A) SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF SUCH COURTS, AND (B) WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT OR THAT ANY SUCH COURT IS AN INCONVENIENT FORUM. Exhibit 1.01-2 26 BORROWER(S) AGREES THAT SERVICE OF PROCESS UPON IT MAY BE MADE BY CERTIFIED OR REGISTERED MAIL, RETURN RECEIPT REQUESTED, AT ITS ADDRESS SPECIFIED BELOW. LENDER MAY SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW AND MAY BRING ANY ACTION OR PROCEEDING AGAINST BORROWER(S) OR WITH RESPECT TO ANY OF ITS PROPERTY IN COURTS IN OTHER PROPER JURISDICTIONS OR VENUES. For purposes of this Note, any assignee or subsequent holder of this Note will be considered the "Lender," and any successor or successors to Borrower will be considered, jointly and severally, the "Borrower." Payment of this Note is secured pursuant to the Existing Security Agreement and other Security Instruments. Debtor's signature below may delivered to Lender by facsimile transmission, and any such facsimile signature shall be deemed for all purposes to constitute an original, manually-executed signature and shall be fully binding to the same extent as if it were in fact Debtor's original, manually- executed signature. NO COURSE OF DEALING BETWEEN BORROWER AND LENDER, NO COURSE OF PERFORMANCE, NO TRADE PRACTICES AND NO EXTRINSIC EVIDENCE OF ANY NATURE MAY BE USED TO CONTRADICT OR MODIFY ANY TERM OF THIS NOTE OR ANY OTHER LOAN DOCUMENT. THIS NOTE IS SUBJECT TO ALL OF THE TERMS AND CONDITIONS SET FORTH IN THE LOAN AGREEMENT. THIS NOTE AND THE OTHER LOAN DOCUMENTS COLLECTIVELY REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS BETWEEN THEM. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. Exhibit 1.01-3 27 IN WITNESS WHEREOF, Borrower has executed this Note effective as of October ___ 1997.

The Shares issuable upon conversion of part or all of the original principal amount of the Note is subject to the following adjustments: (a) Recapitalization, Reclassification and Succession. If any recapitalization of the Borrower or reclassification of its Shares or any merger or consolidation of the Borrower into or with a corporation or other business entity, or the sale or transfer of all or substantially all of the Borrower's assets or of any successor corporation's assets to any other corporation or business entity (any such corporation or other Schedule 2.04-1 29 business entity's being included within the meaning of the term "successor corporation") shall be effected at any time while any principal amount of the Note remains outstanding then, as a condition of such recapitalization, reclassification, merger, consolidation, sale or transfer, lawful and adequate provision shall be made whereby the Lender thereafter shall have the right to receive upon the conversion of the principal amount of the Note then outstanding (at a given time, the "Principal Balance") and in lieu of the Shares immediately theretofore issuable upon the conversion of the Principal Balance, such shares of capital stock, securities or other property as may be issued or payable with respect to or in exchange for a number of outstanding Shares equal to the number of Shares immediately theretofore issuable upon the conversion of the Principal Balance had such recapitalization, reclassification, merger, consolidation, sale or transfer not taken place and, in each such case, the terms of the Loan Agreement shall be applicable to the shares of capital stock or other securities or property receivable upon the conversion of the Principal Balance after such consummation. (b) Subdivision or Combination of Shares. If, at any time while any principal amount of the Note remains outstanding, the Borrower shall subdivide or combine its Shares, the number of Shares purchasable upon conversion of the Principal Balance shall be proportionately adjusted. (c) Certain Dividends and Distributions. If, at any time while any principal amount of the Note remains outstanding, the Borrower shall take a record of the holders of Shares for the purpose of entitling them to receive a dividend payable in, or other distribution of, Shares, then the number of Shares purchasable upon conversion of the Principal Balance shall be adjusted to that number determined by multiplying the number of Shares so purchasable immediately prior to such record date by a fraction (i) the numerator of which shall be the sum of (A) the total number of outstanding Shares immediately prior to such record date and (B) the total number of Shares issuable pursuant to such dividend or distribution, and (ii) the denominator of which shall be the total number of Shares outstanding immediately prior to such record date. (d) Corresponding Conversion Price Adjustment. Whenever the number of Shares purchasable upon the conversion of the Principal Balance is increased or decreased as provided in subsections (b) or (c) above, the Conversion Price shall be adjusted by multiplying the Conversion Price immediately prior to such adjustment by a fraction, the numerator of which shall be the number of Shares purchasable upon the conversion of the Principal Balance immediately prior to such adjustment, and the denominator of which shall be the number of Shares purchasable immediately thereafter. (e) Certain Shares Excluded. The number of Shares outstanding at any given time for purposes of the adjustments set forth in this Section shall exclude any shares then directly or indirectly held in the treasury of the Borrower. (f) Deferral and Cumulation of De Minimis Adjustments. The Borrower shall not be required to make any adjustment of the Conversion Price pursuant to this Section if the amount of such adjustment would be less than one percent (1%) of the Conversion Price in effect immediately before the event that would otherwise have given rise to such adjustment. In such case, however, any adjustment that otherwise would have been required to be made shall be made at the time of and together with the next subsequent adjustment which, Schedule 2.04-2 30 together with any adjustment or adjustments so carried forward, shall amount to not less than one percent (1%) of the Conversion Price in effect immediately before the event giving rise to such next subsequent adjustment. (g) Duration of Adjusted Conversion Price. Following each computation or readjustment of an adjusted Conversion Price as provided in this Section, the new adjusted Conversion Price shall remain in effect until a further computation or readjustment thereof is required. 4. Notices to Lender. (a) Notice of Record Date. In case: (i) the Borrower shall take a record of the holders of Shares (or other capital stock or securities at the time receivable upon the exercisable of the Principal Balance) for the purpose of entitling them to receive any dividend (other than a cash dividend payable out of earned surplus of the Borrower) or other distribution, or any right to subscribe for or purchase any shares of stock of any class or any other securities, or to receive any other right; or (ii) of any capital reorganization of the Borrower, any reclassification of the capital stock of the Borrower, any consolidation with or merger of the Borrower into another corporation, or any conveyance of all or substantially all of the assets of the Borrower to another corporation; or (iii) of any voluntary dissolution, liquidation or winding-up of the Borrower; then, and in each such case, the Borrower shall mail or cause to be mailed to the Lender a notice specifying, as the case may be, (1) the date on which a record is to be taken for the purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or right or (2) the date on which such reorganization, reclassification, consolidation, merger, conveyance, dissolution, liquidation or winding-up is to take place, and the time, if any, is to be fixed, as of which the record holders of Shares shall be entitled to exchange their Shares (or such other capital stock or securities) for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, conveyance, dissolution, liquidation or winding-up. Such notice shall be mailed at least 30 days prior to the record date therein specified or, if no record date shall have been specified, at least 30 days prior to such other specified date. (b) Notice of Adjustments. Whenever any Conversion Price shall be adjusted pursuant to Section 3 hereof, the Borrower shall promptly deliver to the Lender a certificate signed by its President or by any Vice President, and by its Treasurer or any Assistant Treasurer or its Secretary or any Assistant Secretary, setting forth in reasonable detail the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated and the Conversion Price after giving effect to such adjustment. Schedule 2.04-3 31 5. No Requirement to Issue Fractional Shares. The Borrower shall not be required to issue fractional Shares upon conversion of part or all of the Principal Balance pursuant to the Lender's exercise of the Conversion Right. In lieu thereof, the Borrower shall be entitled to pay to the Lender in cash an amount equal (to the nearest cent) to the appropriate fraction of the value (which shall be the last reported sale price if a sale took place within 60 days of the applicable Notice of Exercise or, if none, a deemed value of CDN$0.15 per Share) of a Share on the date that the Borrower receives the Notice of Exercise.

and (b) provide copies of the exercise notices (the "Other Exercise Notices") given to the Borrower by the Other Rightholders pursuant to the Other Agreements; and in the event that the Borrower does not receive an Exercise Notice or one or both of the Other Exercise Notices in respect of a Financing, the Borrower will give notice (in each case a "Second Notice") to such effect to the Lender and/or one or both of the Rightholders, as circumstances require. 1.06 If the Lender fails to give an Exercise Notice within thirty (30) days next following receipt of the applicable Notice or elect in an Exercise Notice to provide less than the Lender's Proportionate Shares of such Financing, the Borrower will then be free for a period of (3) months (subject to the rights of the Other Rightholders to provide the Other Rightholders' Proportionate Shares of such proposed Financing as a result of the timely giving of notice of their intention to do so and their rights under the Other Agreements) to make other arrangements to obtain the unfunded portion of the proposed Financing from Schedule 4.16-1 35 another source, including the Other Rightholders, on the same terms or on terms no less favorable to the Borrower than are set forth in the applicable Notice. 1.07 In the event that one or both of the Other Rightholders elects not to provide all such Other Rightholder's Proportionate Share of such Financing, the Lender may, by further notice to the Borrower given not later than ten (10) days after the Lender's receipt of the Other Exercise Notices or Second Notices, as the case may be, elect to provide some or all of that portion of the Financing (the "Remaining Financing") which one or both of the Other Rightholders (a "Non-participating Rightholder") has not elected to provide; provided, however, that if one of the Other Rightholders (the "Participating Rightholder") also elects to provide some or all of the Remaining Financing, and if the additional elections of the Lender and the Participating Rightholder are greater in the aggregate than the Remaining Financing, then the Lender and the Participating Rightholder shall share in the Remaining Financing pro rata according to their percentage interests set forth herein. 1.08 The failure by Lender in any one or more instances to provide all or any portion of the Lender's Proportionate Share of any Financing shall not deprive the Lender of its right of first refusal in any other instances. 1.09 The right of first refusal granted hereunder is conditional upon consummation of the Closing. 1.10 The right of first refusal granted hereunder will not affect the Borrower's right to obtain fiscal agency or investment banking services that it requires or proposes to obtain during the Term, whether or not in connection with any Financing or any proposed amalgamation, merger, acquisition, takeover, plan of arrangement or other restructuring, including, without limitation, the preparation of fairness opinions and the like. 1.11 The Borrower will not amend the terms of or grant extensions of time in respect of any rights of first refusal previously granted or which may hereafter be granted to either of the Other Rightholders pursuant to the Other Agreement without, at the option of the Lender, amending the terms of or granting extensions of time in respect of the right of first refusal granted to the Lender hereunder in the same manner and to the same extent as the Borrower has agreed to amend the terms of one or both of the Other Agreements or to grant any extension of time in respect of one or both of the Other Agreements. Schedule 4.16-2 36 PROMISSORY NOTE October 16, 1997 US$750,000.00 FOR VALUE RECEIVED, FLOTEK INDUSTRIES INC., an Alberta corporation ("Borrower"), promises to pay to the order of TOSI, L.P., a Texas limited partnership ("Lender"), on or before October 16, 1998, at its office at 3900 Thanksgiving Tower, 1601 Elm Street, Dallas, Texas 75201, or at such other location as Lender may designate, in immediately available funds, SEVEN HUNDRED FIFTY THOUSAND AND NO/100 UNITED STATES DOLLARS (US$750,000.00). Borrower will also pay interest on the unpaid principal balance outstanding from time to time at a fixed rate of ten percent (10%) per annum, payable quarterly in arrears. Interest will be computed on the basis of the actual number of days elapsed and a year comprising 360 days, unless such calculation would result in a usurious interest rate, in which case such interest will be calculated on the basis of a 365 or 366 day year, as the case may be. All past due principal and interest on this Note will, at Lender's option, bear interest at the maximum nonusurious rate of interest ("Highest Lawful Rate") or, if applicable law does not provide for a maximum nonusurious rate of interest, at a rate per annum equal to 18%. Borrower covenants to apply the total amount advanced by Lender hereunder only in the manner set forth in that certain Convertible Loan Agreement of even date herewith between Borrower and Lender (the "Loan Agreement"). Borrower understands and acknowledges that Lender would not be willing to make the loan evidenced hereby but for Borrower's covenant set forth in the immediately- preceding sentence. All undefined capitalized terms used in this Note shall have the meanings respectively ascribed to them in the Loan Agreement. In addition to all principal and accrued interest on this Note, Borrower agrees to pay: (a) all reasonable costs and expenses incurred by or on behalf of Lender and all owners and holders of this Note in attempting to collect this Note through probate, reorganization, bankruptcy or any other proceeding; and (b) reasonable attorneys fees if and when this Note is placed in the hands of an attorney for collection. The outstanding principal amount of the Loan evidenced by this Note shall be convertible into common shares of Borrower in the manner and to the extent set forth in the Loan Agreement. PROMISSORY NOTE MADE BY FLOTEK INDUSTRIES INC. IN FAVOR OF TOSI, L. P. OCTOBER 16, 1997 - PAGE 1 OF 4 37 Borrower and Lender intend to conform strictly to applicable usury laws. Therefore, the total amount of interest (as defined under applicable law) contracted for, charged or collected under this Note will never exceed the Highest Lawful Rate. If Lender contracts for, charges or receives any excess interest, it will be deemed a mistake. Lender will automatically reform the contract or charge to conform to applicable law and, if excess interest has been received, Lender will either refund the excess to Borrower or credit the excess on the unpaid principal amount of this Note. All amounts constituting interest will be spread throughout the full term of this Note in determining whether interest exceeds lawful amounts. The unpaid principal balance of this Note at any time will be the total amount advanced by Lender, less the amount of all payments of principal. Borrower may at any time pay the full amount of this Note without the payment of any premium, penalty or fee. "Loan Document" means this Note and any document or instrument evidencing, securing, guaranteeing or given in connection with this Note including, without limitation, the Loan Agreement, the Warrant and the Registration Rights Agreement. "Obligations" means all principal, interest and other amounts which are or become owing under this Note or any other Loan Document. "Obligor" means Borrower and any guarantor, surety, co-signer, or other person who may now or hereafter be obligated to pay all or any part of the Obligations. Where appropriate, the masculine gender includes the feminine and the neuter and the singular number includes the plural number. Each Obligor severally waives notice, demand, presentment for payment, notice of nonpayment, notice of intent to accelerate, notice of acceleration, protest, notice of protest and the filing of suit and diligence in collecting this Note and all other demands and notices, and consents and agrees that its liabilities and obligations will not be released or discharged by any or all of the following, whether with or without notice to it or any other Obligor, and whether before or after the stated maturity hereof: (i) extensions of the time of payment; (ii) renewals; (iii) acceptances of partial payments; (iv) releases or substitutions of any collateral or any Obligor; and (v) failure, if any, to perfect or maintain perfection of any security interest in any collateral. Each Obligor agrees that acceptance of any partial payment will not constitute a waiver and that waiver of any default will not constitute waiver of any prior or subsequent default. This Note is governed by the laws of the Province of Alberta (exclusive of any such laws that pertain to conflicts of laws). If any provision of this Note is illegal or unenforceable, that illegality or unenforceability will not affect the remaining provisions of this Note.
