Among

FLOTEK INDUSTRIES, INC. (“Lender”),

and

BEAR, STEARNS INTERNATIONAL LIMITED (“Borrower”), through BEAR,

STEARNS & CO. INC., as agent for Borrower (“Borrowing Agent”).

This Agreement sets forth the terms and conditions under which Borrower may borrow from Lender shares of its Common Stock.

The parties hereto agree as follows:

SECTION 1. Certain Definitions. The following capitalized terms shall have the following meanings:

“Business Day” means a day, other than a Saturday or Sunday, on which (i) regular trading occurs in the principal trading market for the Common Stock and (ii) the Clearing Organization is open.

“Cash” means any coin or currency of the United States as at the time shall be legal tender for payment of public and private debts.

“Clearing Organization” means The Depository Trust Company, or, if agreed to by Borrower and Lender, a Securities Intermediary at which Borrower (or Borrowing Agent) and Lender both maintain accounts.

“Closing Price” on any day means, with respect to the Common Stock (i) if the Common Stock is listed or admitted to trading on a U.S. securities exchange registered under the Exchange Act or is included in the OTC Bulletin Board Service (operated by the Financial Industry Regulatory Authority, Inc.), the last reported sale price, regular way, in the principal trading session on such day on such market on which the Common Stock is then listed, admitted to trading or included (or, if the day of determination is not a Business Day, the last preceding Business Day) and (ii) if the Common Stock is not so listed or admitted to trading or if the last reported sale price is not obtainable (even if the Common Stock is listed, admitted to trading or included on such market), the average of the bid prices for the Common Stock obtained from as many dealers in the Common Stock (which may include Borrower or its affiliates), but not exceeding three, as shall furnish bid prices to the Borrower.

“Common Stock” means shares of Common Stock, par value $0.0001 per share, of Lender, or any other security into which the Common Stock shall be exchanged or converted as the result of any merger, consolidation, other business combination, reorganization, reclassification, recapitalization or other corporate action (including, without limitation, a reorganization in bankruptcy).

“Convertible Notes” means the $100,000,000 aggregate principal amount of 5.25% Convertible Senior Notes due 2028 issued by Lender, or up to $115,000,000 aggregate principal amount to the extent the option to purchase additional Convertible Notes (the “Option”) is exercised in full as set forth in the underwriting agreement relating to the Convertible Notes.

“Convertible Notes Settlement Date” means February 14, 2008.

“Cutoff Time” shall mean 10:00 a.m. in the jurisdiction of the Clearing Organization, or such other time on a Business Day by which a transfer of Loaned Shares must be made by Borrower or Lender to the other, as shall be determined in accordance with market practice.

“Exchange Act” means the Securities Exchange Act of 1934, as amended.

“Guarantor” means Bear Stearns Companies Inc.

“Indenture” means the Indenture dated February 14, 2008, as supplemented by the First Supplemental Indenture dated February 14, 2008, each amongst Lender, the guarantors party thereto and American Stock Transfer & Trust Company, as trustee, pursuant to which the Convertible Notes are to be issued, as such Indenture is in effect as of the Convertible Notes Settlement Date.

“Lender’s Designated Account” means the securities account of Lender maintained on the books of Borrower, as Securities Intermediary, and designated “Flotek Industries, Inc.” (account number 353-09741-1-6), established simultaneously with the execution of this Agreement.

“Loaned Shares” means shares of Common Stock initially transferred to the Borrower in a Loan hereunder until such Loan or portion thereof is terminated and a corresponding number of Loaned Shares is transferred to Lender pursuant to this Agreement; provided that in respect of any such share of Common Stock initially transferred to the Borrower by Lender and subsequently transferred by the Borrower to another transferee, “Loaned Shares” means an equivalent number of shares of identical Common Stock. If, as the result of a stock dividend, stock split or reverse stock split, the number of outstanding shares of Common Stock is increased or decreased, then the number of Loaned Shares under outstanding Loans shall, effective as of the payment or delivery date of any such event, be proportionately increased or decreased, as the case may be. If any new or

2

different security (or two or more securities) shall be exchanged for the outstanding shares of Common Stock as the result of any reorganization, merger, consolidation, reclassification, recapitalization or other corporate action (including, without limitation, a reorganization in bankruptcy), such new or different security (or such two or more securities collectively) shall, effective upon such exchange, be deemed to become a Loaned Share in substitution for the former Loaned Share for which such exchange is made, and in the same proportion for which such exchange is made. For purposes of return of Loaned Shares by Borrower or purchase or sale of securities pursuant to Section 4 or Section 10, such term shall mean securities of the same issuer, class and quantity as the Loaned Shares as adjusted pursuant to the two preceding sentences.

“Maximum Number of Shares” means 3,800,000 shares of Common Stock, subject to the following adjustments:

(a) If, as the result of a stock dividend, stock split or reverse stock split, the number of outstanding shares of Common Stock is increased or decreased, the Maximum Number of Shares shall, effective as of the payment or delivery date of any such event, be proportionally increased or decreased, as the case may be.

(b) If, pursuant to a merger, consolidation, other business combination, reorganization, reclassification, recapitalization or other corporate action (including, without limitation, a reorganization in bankruptcy), the Common Stock is exchanged for, or converted into, cash, the Maximum Number of Shares shall be proportionately reduced (to the extent Common Stock is exchanged for, or converted into, cash) on the effective date of such event.

(c) If any Convertible Notes are tendered for conversion to Lender in accordance with the terms of such Convertible Notes, the Maximum Number of Shares shall, effective as of the date Lender delivers cash and/or shares of Common Stock in satisfaction of the related conversion obligation, be reduced by a number of shares of Common Stock (rounded down to the nearest whole share) equal to the product of the Maximum Number of Shares immediately prior to such conversion and a fraction, the numerator of which is the principal amount of Convertible Notes tendered for conversion and the denominator of which is the principal amount of Convertible Notes outstanding as of initial issuance (plus any amount of Convertible Notes issued pursuant to the Option).

(d) Upon the termination of any Loan pursuant to Section 4 the Maximum Number of Shares shall be reduced by the number of Loaned Shares surrendered by Borrower to Lender.

(e) Notwithstanding the foregoing, if, at any time after the Convertible Notes Settlement Date, the Maximum Number of Shares exceeds the product of (i) the aggregate principal amount of Convertible Notes issued on such date plus, as

3

of any time prior to the expiration of the Option, Convertible Notes issuable upon exercise of the Option, divided by $1,000, and (ii) the Conversion Rate (as such term is used in the Indenture), then, effective at such time, the Maximum Number of Shares shall be reduced by such excess.

“Securities Act” means the Securities Act of 1933, as amended.

“Securities Intermediary” means a “securities intermediary” as defined by Section 8-102(a)(14) of the UCC.

“UCC” means the Uniform Commercial Code, as in effect in the State of New York, as in effect from time to time. Any reference to particular sections of the UCC shall be deemed to embrace successor renumbered provisions thereof.

SECTION 2. Loans of Shares; Transfers of Loaned Shares.

(a) Subject to the terms and conditions of this Agreement, Lender hereby agrees to make available for borrowing on the Convertible Notes Settlement Date, a number of shares of Common Stock equal to the Maximum Number of Shares.

(b) Subject to the terms and conditions of this Agreement, Borrower may by written notice to Lender on or prior to the Convertible Notes Settlement Date (a “Borrowing Notice”), seek to initiate a transaction in which Lender will lend Loaned Shares to Borrower through the issuance by Lender of such Loaned Shares to Borrower upon the terms, and subject to the conditions, set forth in this Agreement (each such issuance and loan, a “Loan”). Such Loan shall be confirmed by a schedule and receipt listing the Loaned Shares provided by Lender to Borrower (the “Confirmation”). Such Confirmation shall constitute conclusive evidence with respect to the Loan, including the number of shares of Common Stock that are the subject of the Loan, to which the Confirmation relates, unless a written objection to the Confirmation specifying the reasons for the objection is received by Lender from Borrower within five Business Days after the delivery of the Confirmation to Borrower; provided that in no event shall the delivery of the Confirmation or any such objection thereto delay the transfer of Loaned Shares to which a Borrowing Notice relates pursuant to clause (d) below.

(c) Notwithstanding anything to the contrary in this Agreement, Borrower shall not be permitted to borrow or have any right to take delivery of, or otherwise receive or be deemed to have received, any shares of Common Stock hereunder to the extent (but only to the extent) that after such receipt of such Common Stock (i) the “beneficial ownership” (within the meaning of Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder) of Common Stock by Borrower or any affiliate of Borrower subject to aggregation with Borrower under such Section 11 and such rules would exceed

4

9.9%, as determined by the Borrower in its sole discretion, or (ii) Borrower would be subject to Section 16(b) of the Exchange Act, as determined by the Borrower in its sole discretion, and any Loan hereunder shall be void and have no effect to the extent (but only to the extent) that such “beneficial ownership” would be in excess of 9.9% or Borrower would become subject to Section 16(b) of the Exchange Act. If any delivery owed to Borrower hereunder is not made, in whole or in part, as a result of this provision, Lender’s obligation to make such delivery shall not be extinguished and Lender shall make such delivery as promptly as practicable after, but in no event later than one Business Day after, Borrower gives notice to Lender that such delivery would not result in such “beneficial ownership” being in excess of 9.9% or Borrower becoming subject to Section 16(b) of the Exchange Act. If, notwithstanding the foregoing, any delivery of Common Stock is erroneously made to Borrower or Borrower otherwise receives or is deemed to have received Common Stock in excess of the foregoing limitation contrary to the first sentence of this clause (c), such Common Stock shall remain the property of the Lender and the Borrower shall be deemed to hold the same as bailee of Lender and shall have no voting, dispositive control or pecuniary interest with respect thereto.

(d) Lender shall transfer Loaned Shares to Borrower on or before the Cutoff Time on the date specified in the Borrowing Notice for the commencement of a Loan, which date shall not be earlier than the third Business Day following receipt by Lender of the Borrowing Notice. Delivery of the Loaned Shares to Borrower shall be made in the manner set forth under Section 11 below.

SECTION 3. Loan Fee. Borrower agrees to pay Lender a single loan fee per Loan (a “Loan Fee”) equal to $0.0001 per Loaned Share. The Loan Fee shall be paid by Borrower on or before the time of transfer of the Loaned Shares pursuant to Section 2(d) on a delivery-versus-payment basis through the facilities of the Clearing Organization. Lender agrees that the Loan Fee will constitute consideration for the issuance of the Loaned Shares to be issued by Lender.

SECTION 4. Loan Terminations.

(a) Borrower may terminate all or any portion of a Loan on any Business Day by giving written notice thereof to Lender and transferring the corresponding number of Loaned Shares to Lender, without any consideration being payable in respect thereof by Lender to Borrower.

(b) All outstanding Loans, if any, shall terminate on the date this Agreement terminates pursuant to Section 13 (the “Facility Termination Date”) and all Loaned Shares under outstanding Loans shall be delivered by Borrower to Lender, without any consideration being payable in respect thereof by Lender to Borrower, no later than the fifth Business Day following the Facility Termination Date.

5

(c) If on any date, the aggregate number of Loaned Shares under outstanding Loans exceeds the Maximum Number of Shares, the number of Loaned Shares in excess of the Maximum Number of Shares shall be delivered by Borrower to Lender, without any consideration being payable in respect thereof by Lender to Borrower, no later than the third Business Day following such date. Upon receipt of a conversion notice from any holder of Convertible Notes, Lender shall notify Borrower within two Business Days of receipt of such conversion notice.

(d) If, as a result of complying with this Section 4 as promptly as reasonably practicable (but subject to applicable law, regulation or policy), (i) the “beneficial ownership” (within the meaning of Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder) of Common Stock by Borrower or any affiliate of Borrower subject to aggregation with Borrower under such Section 11 and such rules would exceed 9.9%, as determined by Borrower in its sole discretion, or (ii) Borrower would be subject to Section 16(b) of the Exchange Act, as determined by Borrower in its sole discretion, then Borrower shall be permitted to extend the date on which Loaned Shares are due under this Section 4 for all or a portion of the corresponding delivery obligation but in no event longer than such time to allow Borrower to return such Loaned Shares, through one transaction or a series of transactions, without causing such “beneficial ownership” to be in excess of 9.9% or Borrower to become subject to Section 16(b) of the Exchange Act, as determined by the Borrower in its sole discretion. In addition, if Borrower is unable to satisfy its obligations to deliver any Common Stock under this Section 4 due to illiquidity in the market for Common Stock, Borrower shall, upon prior written notice to Lender, deliver such Common Stock as promptly as reasonably practicable thereafter.

SECTION 5. Distributions.

(a) If Lender pays a cash dividend or makes a cash distribution in respect of all of its outstanding Common Stock, Borrower shall pay to Lender, within one Business Day after the payment of such dividend or distribution, an amount in cash equal to the product of (i) the amount per share of such dividend or distribution and (ii) the aggregate number of Loaned Shares under outstanding Loans as of the record date of such dividend or distribution.

(b) If Lender makes a distribution in respect of all of its outstanding Common Stock in property or securities, including any options, warrants, rights or privileges in respect of securities (other than a distribution of Common Stock as to which the number of Loaned Shares shall be adjusted pursuant to the definition of “Loaned Shares,” but including any options, warrants, rights or privileges exercisable for, convertible into or exchangeable for Common Stock) (a “Non-Cash Distribution”), then (i) Non-Cash Distributions shall be treated as additional Loans of such Non-Cash Distribution in an amount equal to the product

6

of (x) the amount per share of Common Stock of such Non-Cash Distribution and (y) the aggregate number of Loaned Shares under outstanding Loans as of the record date of such dividend or distribution, and (ii) the definition of “Loaned Share” shall be deemed to be modified to include the per share of Common Stock kind and amount of such Non-Cash Distribution.

SECTION 6. Rights in Respect of Loaned Shares.

Subject to the terms of this Agreement, and except as otherwise agreed by Borrower and Lender, Borrower, insofar as it is the record owner of Loaned Shares, shall have all of the incidents of ownership in respect of any such Loaned Shares until such Loaned Shares are required to be delivered to Lender in accordance with the terms of this Agreement, including the right to transfer the Loaned Shares to others. Borrower agrees that it or any of its affiliates that are the record owner of any Loaned Shares initially transferred to Borrower from Lender as a Loan hereunder will not vote or provide any consent or take any similar action with respect to such Loaned Shares on any matter submitted to a vote of Lender’s shareholders during the term of the Loan; provided, however that, for the avoidance of doubt, this sentence shall only apply to Loaned Shares transferred to Borrower that have not been offered and sold in a registered public offering in accordance with the terms of the Underwriting Agreement dated as of the date hereof among Borrower, Lender and Borrowing Agent or returned to Lender in accordance with the terms of this Agreement.

SECTION 7. Representations and Warranties.

(a) Each of Borrower and Lender represents and warrants to the other that:

(ii) it has taken all necessary action to authorize such execution, delivery and performance;

(iii) this Agreement constitutes its legal, valid and binding obligation enforceable against it in accordance with its terms;

except, in the case of each of clauses (C) and (D), for any such violation, contravention or default that would not reasonably be expected to have a material adverse effect on the financial condition, business, properties or results of operations of Lender and its subsidiaries, or Borrower and its affiliates, as applicable, taken as a whole; provided that any violation, contravention or default that would impact the performance of any party’s obligations under this Agreement shall be deemed to have a material adverse effect on the financial condition, business, properties or results of operations of such party and not qualify for the exception to clauses (C) and (D) described above; and

(v) this Agreement is not unsuitable for it in the light of such party’s financial situation, investment objectives and needs and it is entering into this Agreement in reliance upon such tax, accounting, regulatory, legal and financial advice as it deems necessary and not upon any view expressed by the other or the Borrowing Agent.

(c) Lender represents and warrants to Borrower, as of the date hereof, and as of the date any Loaned Shares are transferred to Borrower in respect of any Loan hereunder, that the outstanding shares of Common Stock are listed on The New York Stock Exchange (the “NYSE”) and the Loaned Shares have been approved for listing on the NYSE, subject to official notice of issuance.

(d) Lender represents and warrants to Borrower, as of the date hereof, and as of the date any Loaned Shares are transferred to Borrower in respect of any Loan hereunder, that Lender is not “insolvent” (as such term is defined under Section 101(32) of Title 11 of the United States Code (the “Bankruptcy Code”) and any applicable state law) and Lender would be able to purchase the Maximum Number of Shares in compliance with the laws of Lender’s jurisdiction of organization.

(e) The representations and warranties of Borrower and Lender under this Section 7 shall remain in full force and effect at all times during the term of this Agreement and shall survive the termination of this Agreement for any reason.

8

SECTION 8. Covenants.

(a) Borrower covenants and agrees with Lender that, in so far as it is the record owner of any Loaned Shares transferred to Borrower by Lender as a Loan hereunder and offered pursuant to a registered public offering on or about the date hereof, such Loaned Shares will be used for the purpose of directly or indirectly facilitating the sale of the Convertible Notes and the hedging of the Convertible Notes by the holders thereof.

(b) Borrower covenants and agrees with Lender that it will not transfer or dispose of any Loaned Shares transferred to Borrower by Lender as a Loan hereunder of which it is the record owner except pursuant to a registration statement that is effective under the Securities Act; provided that Borrower may transfer any such Loaned Shares to any of its affiliates without a registration statement so long as such affiliate transferee does not transfer or dispose of such Loaned Shares to any non-affiliated transferee except pursuant to a registration statement that is effective under the Securities Act.

(c) Lender agrees and acknowledges that Borrower has represented to Lender that Borrower is a “financial institution,” “swap participant” and “financial participant” within the meaning of Sections 101(22), 101(53C) and 101(22A) of Title 11 of the Bankruptcy Code. The parties hereto further agree and acknowledge (A) that this Agreement is intended to be a “securities contract,” as such term is defined in Section 741(7) of the Bankruptcy Code, with respect to which each payment and delivery hereunder is a “settlement payment,” or “margin payment,” as such terms are defined in Section 741(8) and Section 741(5) of the Bankruptcy Code, and a “swap agreement,” as such term is defined in Section 101(53B) of the Bankruptcy Code, with respect to which each payment and delivery hereunder is a “transfer,” as such term is defined in Section 101(54) of the Bankruptcy Code, and (B) that Borrower is intended to be entitled to the protections afforded by, among other sections, Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560 of the Bankruptcy Code.

(d) Lender covenants and agrees that, on any day on which Lender effects any repurchase of shares of Common Stock, Lender shall give Borrower a written notice of the number of its outstanding shares of Common Stock (a “Repurchase Notice”) if, following such repurchase, the number of outstanding shares of Common Stock shall have decreased by more than 1.0% since the immediately preceding Repurchase Notice (or, in the case of the first such Repurchase Notice, the number of outstanding shares of Common Stock as of the date hereof); provided that, as of any date, for purposes of calculating the number of outstanding shares of Common Stock as of the date of the immediately preceding Repurchase Notice, such number shall be adjusted as set forth in clauses (a) and (b) of the definition of “Maximum Number of Shares” above, to the same extent the number of shares of Common Stock are adjusted therein, and

9

only to the extent that any of the events listed in such clauses (a) and (b) have occurred between the date of the immediately preceding Repurchase Notice and such date.

(e) Lender covenants and agrees that, unless otherwise agreed to by Borrower in writing, Lender shall not, nor shall cause any other person to, directly or indirectly, purchase shares of Common Stock such that, after giving effect to such purchase, the aggregate number of Loaned Shares under outstanding Loans shall be in excess of 25% of the number of outstanding shares of Common Stock at such time.

SECTION 10. Lender’s Remedies.

(a) Notwithstanding anything to the contrary herein, if Borrower is required to return Loaned Shares pursuant to Section 4 and, on the date on which Borrower is required to return Loaned Shares pursuant to Section 4, the purchase of Common Stock by Borrower in an amount equal to all or any portion of the number of Loaned Shares to be delivered to Lender shall 1) be prohibited by any law, rules or regulation of any governmental authority to which it is or would be subject, 2) violate, or would upon such purchase likely violate, any order or prohibition of any court, tribunal or other governmental authority, 3) require the prior consent of any court, tribunal or governmental authority prior to any such repurchase or 4) subject Borrower, in the commercially reasonable judgment of Borrower, to any liability or potential liability under any applicable federal securities laws (other than Section 11 and Section 16(b) of the Exchange Act or illiquidity in the market for Common Stock, in which events Section 4(d) hereof shall govern) (each of (i), (ii), (iii) and (iv), a “Legal Obstacle”), then, in each case, Borrower shall immediately notify Lender of the Legal Obstacle and the basis therefor, whereupon Borrower’s obligation to deliver Loaned Shares to Lender shall be suspended until such time as no Legal Obstacle with respect to such obligations shall exist (a “Repayment Suspension”). Following the occurrence of and during the continuation of any Repayment Suspension, Borrower shall use its reasonable best efforts to remove or cure the Legal Obstacle as soon as practicable; provided that, to the extent such Legal Obstacle is caused, directly or indirectly by Lender (including a bankruptcy or insolvency of Lender), Lender shall promptly reimburse all reasonable costs and expenses (including legal counsel to Borrower) incurred or, at Borrower’s election, provide reasonably adequate surety or guarantee for any such costs and expenses that may be incurred by Borrower, in each case in removing or curing such Legal Obstacle.

12

If Borrower is unable to remove or cure the Legal Obstacle within a reasonable period of time under the circumstances, Borrower shall pay to Lender, in lieu of the delivery of Loaned Shares otherwise required to be delivered, an amount in immediately available funds (the “Replacement Cash”) equal to the product of the Closing Price as of the Business Day immediately preceding the date Borrower makes such payment and the number of Loaned Shares otherwise required to be delivered.

(b) If Borrower shall fail to deliver Loaned Shares to Lender on the due date when any Loan is terminated under Section 4 or Borrower shall fail to pay the Replacement Cash to Lender in accordance with Section 10(a) above (to the extent Borrower is permitted and elects to pay Replacement Cash), then, in either case, in addition to any other remedies available to Lender under this Agreement or under applicable law, Lender shall have the right (without further notice to Borrower) to purchase a like number of shares of Common Stock (and, Non-Cash Distributions, if applicable pursuant to Section 5(b)) (“Replacement Shares”) in the principal market for such securities in a commercially reasonable manner (and Lender shall promptly notify Borrower of the aggregate purchase price of the Replacement Shares upon the exercise of such right); provided that Lender shall not be permitted to exercise its right to purchase Replacement Shares if Borrower is delivering Loaned Shares to Lender in accordance with Section 4(d), and provided further that if any Repayment Suspension or failure to deliver shall exist and be continuing, Lender shall not be permitted to exercise its right to purchase Replacement Shares unless Borrower shall fail to deliver the Loaned Shares or pay the Replacement Cash to Lender in accordance with Section 10(a) above. To the extent Lender shall exercise such right, Borrower’s obligation to return a like amount of Loaned Shares or to pay the Replacement Cash, as applicable, shall terminate and Borrower shall be liable to Lender for the purchase price of such Replacement Shares (plus all other amounts, if any, due to Lender hereunder). The purchase price of Replacement Shares purchased under this Section 10 shall include broker’s fees and commissions and all other reasonable costs, fees and expenses related to such purchase and sale. In the event Lender exercises its rights under this Section 10, Lender may elect in its sole discretion, in lieu of purchasing all or a portion of the Replacement Shares, to be deemed to have made such purchase of Replacement Shares for an amount equal to the Closing Price of the Common Stock on the date Lender elects to exercise this remedy. The parties hereby agree that repurchase of the Replacement Shares in a manner intended to allow the Lender to avail itself of the safe harbor provided by Rule 10b-18 under the Exchange Act shall be considered commercially reasonable.

SECTION 11. Transfers.

(a) All transfers of Loaned Shares to Borrower hereunder shall be made by the crediting by a Clearing Organization of such financial assets to the Borrower’s “securities account” (within the meaning of Section 8-501 of the UCC)

13

maintained with such Clearing Organization. All transfers of Loaned Shares to Lender hereunder shall be made by the crediting of such Loaned Shares to Lender’s Designated Account (whereupon, for the avoidance of doubt, such Loaned Shares credited to Lender’s Designated Account shall become the property of Lender, and Borrower shall have no voting, dispositive control or pecuniary interest with respect thereto). In every transfer of “financial assets” (within the meaning of Section 8-102(a)(9) of the UCC) hereunder, the transferor shall take all steps necessary (i) to effect a delivery of such financial assets to the transferee under Section 8-301 of the UCC, or to cause the creation of a security entitlement in favor of the transferee in such financial assets under Section 8-501 of the UCC, (ii) to enable the transferee to obtain “control” (within the meaning of Section 8-106 of the UCC), and (iii) to provide the transferee with comparable rights under any similar law or regulation of any other jurisdiction that is applicable to such transfer.
