If any Borrower or any other Security Party or any of their Subsidiaries pays any consideration to any holder of Securities for such holder’s consent to any amendment, modification or waiver hereunder, such party shall also pay each other holder granting its consent hereunder equivalent consideration computed on a pro rata basis.

8.5 Survival of Agreement. All covenants, representations and warranties contained in the Investment Documents or made in writing by each Security Party in connection herewith or therewith shall survive the execution and delivery of the Investment Documents and the consummation of the transactions contemplated hereby and thereby, regardless of any investigation made by any Purchaser or on its behalf. In addition, the obligations of each Security Party pursuant to Sections 8.1, 8.16 and 8.17 shall survive the repayment of all amounts payable pursuant to this Agreement, the Notes and the Warrants.

8.6 No Setoffs, Etc. All payments hereunder and under the Securities and any notes issued in exchange for any Securities shall be made by each Security Party without setoff, offset, deduction or counterclaim, free and clear of all taxes, levies, imports, duties, fees and charges, and without any withholding, restriction or conditions imposed by any governmental authority. If any Security Party shall be required by any law, statute, rule or regulation to deduct, setoff or withhold any amount from or in respect of any payment to any Purchaser hereunder or under the Securities or any notes issued in exchange for any Securities, then the amount so payable to such Purchaser shall be increased as may be necessary so that, after making all required deductions, setoffs and withholdings, such Purchaser shall receive an amount equal to the sum they would have received had no such deductions, setoffs or withholding been made.

8.7 Successors and Assigns. All covenants and agreements contained in this Agreement by or on behalf of any of the parties hereto shall bind and inure to the benefit of the respective successors and assigns of the parties hereto whether or not so expressed; provided, that no Borrower shall be permitted to assign or delegate, and each Borrower shall prohibit each other Security Party and its Subsidiaries from assigning or delegating, its rights or obligations under this Agreement, the Securities or any notes issued in exchange for any Securities. In addition, and whether or not any express assignment has been made, the provisions of this Agreement which are for any Purchaser’s benefit as a purchaser or holder of Securities, notes issued in exchange for any Securities are also for the benefit of, and enforceable by, any subsequent holder of the same. Except as otherwise expressly provided herein, nothing expressed in or implied from any Investment Document is intended to give, or shall be construed to give, any Person, other than the parties hereto and thereto and their permitted successors and assigns, any benefit or legal or equitable right, remedy or claim under or by virtue of this Agreement or any such other document. Any agreement or covenant in any Investment Document obligating any issuer of an Capital Stock held by a Purchaser or subsequent holder to take any action or to refrain from taking any action, shall similarly obligate any other Person into or with which such issuer is merged, consolidated, combined or reorganized.

8.8 Aggregation. For purposes of the Investment Documents, all holdings of Securities by Persons who are Affiliates of each other shall be aggregated for purposes of meeting any threshold tests under the Investment Documents.

8.9 Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision shall be ineffective

only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement and shall be reformed and enforced to the maximum extent permitted under applicable law.

8.10 Counterparts. This Agreement may be executed in two or more counterparts, any one of which need not contain the signatures of more than one party, but all such counterparts taken together shall constitute one and the same Agreement.

8.11 Descriptive Headings. The descriptive headings of this Agreement and the Securities are inserted for convenience only and do not constitute a substantive part of this Agreement.

8.12 Governing Law. The corporation laws of the State of Missouri shall govern all issues and questions concerning the relative rights and obligations of the Security Parties and the holders of their Capital Stock. All other issues and questions concerning the construction, validity, enforcement and interpretation of this Agreement and the schedules hereto and (except as otherwise expressly provided therein) the exhibits hereto shall be governed by, and construed in accordance with, the laws of the State of Missouri, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Missouri or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Missouri. In furtherance of the foregoing, the internal law of the State of Missouri shall control the interpretation and construction of this Agreement (and all schedules and exhibits hereto), even though under that jurisdiction’s choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily apply.

8.13 Notices. All notices, demands or other communications to be given or delivered under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given when delivered personally to the recipient, sent to the recipient by reputable overnight courier service (charges prepaid), mailed to the recipient by certified or registered mail, return receipt requested and postage prepaid or sent via facsimile to the number set forth below with a copy mailed to the recipient as set forth above.

To the Purchasers:

or to such other address or to the attention of such other person as the recipient party has specified by prior written notice to the sending party.

8.14 Construction. The parties hereto 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 hereto, 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. The parties intend that each representation, warranty and covenant contained herein shall

have independent significance. If any party has breached any representation, warranty or covenant contained herein in any respect or any Event of Default shall occur, the fact that there exists another representation, warranty or covenant or Event of Default relating to the same subject matter (regardless of the relative levels of specificity) which such party has not breached shall not detract from or mitigate the fact that such party is in breach of the first representation, warranty or covenant or that the first Event of Default shall have occurred.

8.15 Complete Agreement. This Agreement, those documents expressly referred to herein, and the other documents of even date herewith delivered or executed in connection with the transactions contemplated hereby embody the complete agreement and understanding among the parties and supersede any prior agreements or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way.

8.16 Indemnification. In consideration of each Purchaser’s execution and delivery, of this Agreement and purchase of the Securities hereunder and in addition to all of each Borrower’s other obligations under this Agreement and in addition to all other rights and remedies available at law or in equity, each Borrower shall, and shall cause each other Security Party and their Subsidiaries to, defend, protect and indemnify the Purchasers and each other holder of Securities, any notes issued in exchange for any Securities and all of their officers, managers, directors, stockholders, members, partners, limited partners, Affiliates, employees, agents, representatives, successors and assigns (including those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”), and save and hold each of them harmless from and against, and pay on behalf of or reimburse such part), on demand as and when incurred, any and all actions, causes of action, suits, claims, losses (including diminutions in value and consequential damages), costs, penalties, fees, liabilities and damages and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), including reasonable attorneys’ fees and disbursements, interest and penalties and all amounts paid in investigation, defense or settlement of any of the foregoing and claims relating to any of the foregoing (the “Liabilities”), incurred by the Indemnitees or any of them as a result of, or arising out of, or relating to: (i) any breach or inaccuracy of any representation or warranty of any Borrower or Security Party contained in this Agreement or any other Transaction Document or any non-fulfillment or breach of any covenant or agreement of any Borrower or Security Party contained in this Agreement or any other Transaction Document; (ii) the execution, delivery, performance or enforcement of the Investment Documents, any Governing Documents of any Security Party or its Subsidiaries and any other instrument, document or agreement executed pursuant hereto or thereto of any Security Party or its Subsidiaries by any of the Indemnitees, except to the extent any such Liabilities are caused by the particular Indemnitee’s gross negligence or willful misconduct; and (iii) the past, present or future environmental condition of any property owned, operated or used by any Security Party, any of its Subsidiaries, their predecessors or successors or of any offsite treatment, storage or disposal location associated therewith, including, without limitation, the presence on or under, or the escape, seepage, leakage, spillage, discharge, emission, release or threatened release into, onto or from, any such property or location of any toxic, chemical or hazardous substance, material or waste (including, without limitation, any losses, liabilities, damages, injuries, penalties, fees, costs, expenses or claims asserted or arising under any Environmental and Safety Requirement) regardless of whether caused by, or within the control of, such Security Party or any of its Subsidiaries. To the extent that the foregoing undertaking by each Security Party may be unenforceable for any reason, each Security Party shall make the maximum contribution to the payment and satisfaction of each of the Liabilities which is permissible under applicable law. If there are insufficient funds to meet the obligations of the Security Parties and their Subsidiaries under this Section 8.16, any indemnification payments made pursuant to this Section, to the extent such indemnification relates to Liabilities which are common to all Purchasers, shall be made pro rata, based on the percentage that the Warrants purchased by each such Purchaser, as set forth opposite such Purchaser’s name on the Schedule of Purchasers attached hereto, bears to the total

aggregate Warrants purchased by all Purchasers, as set forth on the Schedule of Purchasers attached hereto.

8.17 Payment Set Aside. To the extent that any payment or payments are made to any Purchaser hereunder or under the Securities, any notes issued in exchange for any Securities or such Purchaser enforces its rights or exercises its right of setoff hereunder or thereunder, and such payment or payments or the proceeds of such enforcement or setoff or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to such payor, a trustee, receiver or any other Person under any law, statute, rule or regulation (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

8.18 Jurisdiction and Venue. Each of the parties: (i) submits to the jurisdiction of any state or federal court sitting in St. Louis County, Missouri in any legal suit, action or proceeding arising out of or relating to this Agreement, the Securities, any notes issued in exchange for any Securities; (ii) agrees that all claims in respect of the action or proceeding may be heard or determined in any such court; and (iii) agrees not to bring any action or proceeding arising out of or relating to this Agreement, the Securities, any notes issued in exchange for any Securities in any other court. Each of the parties waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety or other security that might be required of any other party with respect thereto. Any party may make service on any other party by sending or delivering a copy of the process to the party to be served at the address and in the manner provided for the giving of notices in Section 8.13. Each party agrees that a final judgment in any action or proceeding so brought shall be conclusive and may be enforced by suit on the judgment or in any other manner provided by law. Nothing herein shall affect the right to serve process in any other manner permitted by law, statute, rule or regulation or shall limit the right of any Purchaser to bring proceedings against any Security Party in the courts of any other jurisdiction. To the extent provided by any law, statute, rule or regulation, should any Security Party, after being so served, fail to appear or answer to any summons, complaint, process or papers so served within the number of days prescribed by law after the mailing thereof, such Security Party shall be deemed in default and an order and/or judgment may be entered by the court against such Security Party as demanded or prayed for in such summons, complaint, process or papers. The exclusive choice of forum for each Security Party set forth in this Section 8.18 shall not be deemed to preclude the enforcement by any Purchaser or any holder of Securities or notes issued in exchange for any Securities of any judgment obtained in any other forum or the taking by such Purchaser or any holder of Securities or notes issued in exchange for any Securities of any action to enforce the same in any other appropriate jurisdiction, and each Security Party hereby waives the right to collaterally attack any such judgment or action.

8.19 Waiver of Right to Jury Trial. EACH BORROWER, ON ITS OWN BEHALF AND ON BEHALF OF EACH OTHER SECURITY PARTY AND ITS SUBSIDIARIES, AND EACH HOLDER OF SECURITIES AND NOTES ISSUED IN EXCHANGE FOR ANY SECURITIES HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE LAW, TRIAL BY JURY IN ANY LITIGATION IN ANY COURT WITH RESPECT TO, IN CONNECTION WITH, OR ARISING OUT OF THIS AGREEMENT, THE SECURITIES, ANY NOTES ISSUED IN EXCHANGE FOR ANY SECURITIES OR THE VALIDITY, PROTECTION, INTERPRETATION, COLLECTION OR ENFORCEMENT THEREOF. EACH BORROWER, ON ITS OWN BEHALF AND ON BEHALF OF EACH OTHER SECURITY PARTY AND ITS SUBSIDIARIES, AGREES THAT THIS SECTION IS A SPECIFIC AND MATERIAL ASPECT OF THIS AGREEMENT AND ACKNOWLEDGES THAT

THE PURCHASERS WOULD NOT PURCHASE THE SECURITIES HEREUNDER IF THIS SECTION WERE NOT PART OF THIS AGREEMENT.

8.20 Certain Waivers. Each Borrower hereby waives diligence, presentment, protest and demand and notice of protest and demand, dishonor and nonpayment of the Notes and any notes issued in exchange for any Securities, and expressly agrees that the Notes and any notes issued in exchange for any Securities, or any payment thereunder, may be extended from time to time and that the holder thereof may accept security for the Notes and any notes issued in exchange for any Securities or release security for the Notes and any notes issued in exchange for any Securities, all without in any way affecting the liability of such Borrower thereunder.

8.21 Joint and Several Liability of the Security Parties. Each Security Party shall be jointly and severally liable hereunder and under each of the Investment Documents to which it is a party with respect to all obligations hereunder and thereunder (the “Security Party Obligations”), regardless of which Security Party actually receives the proceeds from the issuance of the Securities, or the manner in which the Borrowers, any other Security Party or any Purchaser account therefor in their respective books and records. Notwithstanding the foregoing: (i) each Security Party’s obligations and liabilities with respect to the proceeds from the issuance of the Securities which it receives, and related fees, costs and expenses; and (ii) each Security Party’s obligations and liabilities arising as a result of the joint and several liability of a Borrower hereunder with respect to proceeds of the Notes received by any other Security Party, together with the related fees, costs and expenses, shall be separate and distinct obligations, both of which are primary obligations of such Security Party. Neither the joint and several liability of any Security Party shall be impaired or released by (a) the failure of any Purchaser, any successor or assigns thereof, or any holder of any Securities, any notes issued in exchange for any Securities or any of the Security Party Obligations to assert any claim or demand or to exercise or enforce any right, power or remedy against any Security Party or its Subsidiaries, any other Person or otherwise, (b) any extension or renewal for any period (whether or not longer than the original period) or exchange of any of the Security Party Obligations or the release or compromise of any obligations of any nature of any Person with respect thereto, (c) the surrender, release or exchange of all or any part of any property securing payment, performance and/or observance of any of the Security Party Obligations or the compromise or extension or renewal for any period (whether or not longer than the original period) of any obligations of any nature of any Person with respect to any such property, (d) any action or inaction on the part of any Purchaser, or any other event or condition with respect to any other Security Party, including, without limitation, any such action or inaction or other event or condition, which might otherwise constitute a defense available to, or a discharge of, such other Security Party, or a guarantor or surety of or for any or all of the Security Party Obligations or (e) any other act, matter or thing (other than payment or performance of the Security Party Obligations) which would or might, in the absence of this provision, operate to release, discharge or otherwise prejudicially affect the obligations of such or any other Security Party.

8.22 Several Liability of Purchasers. The liabilities and obligations of the Purchasers under the Investment Documents, including, but not limited to, the Purchasers’ obligation to purchase the Securities hereunder are several obligations of the Purchasers. No Purchaser shall have any obligation or liability arising under any Investment Document or otherwise as a result of any other Purchaser’s breach or default hereunder or thereunder. EACH BORROWER, ON ITS OWN BEHALF AND ON BEHALF OF EACH OTHER SECURITY PARTY AND ITS SUBSIDIARIES, SHALL BE DEEMED TO HAVE WAIVED ANY SUCH ACTION, CLAIM, RIGHT OR CAUSE OF ACTION ANY SUCH PARTY MAY HAVE AGAINST ANY SUCH PURCHASER.

THE SECURITIES REPRESENTED BY THIS INSTRUMENT WERE ORIGINALLY ISSUED ON MARCH 21, 2007, AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THE TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE CONDITIONS SPECIFIED IN THE NOTE AND WARRANT PURCHASE AGREEMENT, DATED AS OF MARCH 21, 2007, AND AS AMENDED AND MODIFIED FROM TIME TO TIME, AMONG THE BORROWERS, THE INITIAL HOLDER(S) HEREOF AND CERTAIN INVESTORS, WHO FROM TIME TO TIME BECOME PARTIES THERETO IN ACCORDANCE WITH THE PROVISIONS THEREOF, AND THE BORROWERS RESERVE THE RIGHT TO REFUSE THE TRANSFER OF SUCH SECURITY UNTIL SUCH CONDITIONS HAVE BEEN FULFILLED WITH RESPECT TO SUCH TRANSFER.

10% SUBORDINATED SECURED PROMISSORY NOTE

March 21, 2007

$100,000.00

Siboney Corporation, a Maryland corporation, and Siboney Learning Group, Inc., a Texas corporation (collectively, the “Borrowers”), hereby jointly and severally promise to pay to the order of ____________ the principal amount of One Hundred Thousand Dollars ($100,000.00) together with interest thereon calculated from the date hereof in accordance with the provisions of this Note.

This Note was issued pursuant to a Note and Warrant Purchase Agreement, dated as of March 21, 2007 (as amended and modified from time to time, the “Purchase Agreement”), among the Borrowers and certain investors, and this Note is one of the “Notes” referred to in the Purchase Agreement. The Purchase Agreement contains terms governing the rights of the holder of this Note, and all provisions of the Purchase Agreement are hereby incorporated herein in full by reference. Unless otherwise indicated herein, capitalized terms used in this Note have the same meanings set forth in the Purchase Agreement. The obligations evidenced by the Notes are secured by a security interest in the Borrowers’ assets granted pursuant to a Security Agreement dated the date hereof among the Borrowers and the holders of the Notes.

1. Payment of Interest. Except as otherwise expressly provided in the Purchase Agreement, interest shall accrue at the rate of 10% per annum (computed on the basis of a 360-day year and the actual number of days elapsed in any year) on the unpaid principal amount of this Note outstanding from time to time, or (if less) at the highest rate then permitted under applicable law; provided, however, that upon the occurrence of any Event of Default, and during the continuation thereof,

the unpaid principal amount, and the past due interest, if any, of this Note shall bear interest at a rate of 12% per annum. The Borrowers shall pay to the holder of this Note all accrued interest on the last day of each calendar quarter, beginning June 30, 2007, which may, at the option of the Borrowers, be paid in kind rather than in cash (i.e., such interest shall be capitalized when due and added to the principal balance of this Note). Any accrued interest which for any reason has not theretofore been paid shall be paid in full on the date on which the final principal payment on this Note is made. Interest shall accrue on any principal payment due under this Note and, to the extent permitted by applicable law, on any interest which has not been paid on the date on which it is due and payable at the same rate at which such interest is then accruing on the principal amount of this Note, in either case, until such time as payment therefore is actually delivered to the holder of this Note.

2. Payment of Principal on Note.

(a) Scheduled Payments. The Borrowers shall pay the principal amount of $100,000 (or such lesser principal amount then outstanding) to the holder of this Note on March 21, 2009, together with all accrued and unpaid interest on the principal amount being repaid.

(b) Prepayments. The Borrowers may, at any time and from time to time, prepay all or any portion of the outstanding principal amount of the Notes, without penalty, pro rata among the holders of the Notes on the basis of the outstanding principal amount of the Note held by each holder; provided, that (A) such prepayment is not prohibited by the provisions of the Subordination Agreement and (B) the Borrowers have paid all interest on the Notes accrued through the date ten days prior to the date of prepayment specified in the Borrowers’ notice referred to in subparagraph (b)(ii) below. In connection with each prepayment of principal hereunder, the Borrowers shall also pay all accrued and unpaid interest on the principal amount of the Notes being repaid. A prepayment of less than all of the outstanding principal amount of each of the Notes shall not relieve the Borrowers of their obligation to make scheduled payments on each of the Notes on the scheduled payment dates pursuant to Section 2(a).

3. Holder’s Records. The holder of this Note shall record in its books and records the date and amount of each payment of principal and/or interest made by Borrowers with respect thereto (including any payment in kind of interest as described in Section 1 above); provided, however, that the obligation of Borrowers to repay this Note shall be absolute and unconditional, notwithstanding any failure of the holder of this Note to make any such recordation or any mistake by the holder of this Note in connection with any such recordation. The books and records of the holder of this Note showing the account between the holder of this Note and Borrowers shall be admissible in evidence in any action or proceeding and shall constitute prima facie proof of the items therein set forth.

4. Amendment and Waiver. Except as otherwise expressly provided herein, the provisions of the Notes may be amended and the Borrowers may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Borrowers have obtained the written consent of the holders of 100% of the outstanding principal amount of the Notes.

5. Cancellation. After all principal and accrued interest at any time owed on this Note has been paid in full, this Note shall be surrendered to the Borrowers for cancellation and shall not be reissued.

6. Payments. All payments to be made to the holders of the Notes shall be made in the lawful money of the United States of America in immediately available funds.

7. Place of Payment. Payments of principal and interest shall be delivered to ______________ at his address on the records of the Borrowers, or to such other address or to the attention of such other person as specified by prior written notice to the Borrowers.

8. Business Days. If any payment is due, or any time period for giving notice or taking action expires, on a day which is a Saturday, Sunday or legal holiday in the State of Missouri, the payment shall be due and payable on, and the time period shall automatically be extended to, the next Business Day immediately following such Saturday, Sunday or legal holiday, and interest shall continue to accrue at the required rate hereunder until any such payment is made.

9. Usury Laws. It is the intention of the Borrowers and the holder of this Note to conform strictly to all applicable usury laws now or hereafter in force, and any interest payable under this Note shall be subject to reduction to the amount not in excess of the maximum legal amount allowed under the applicable usury laws as now or hereafter construed by the courts having jurisdiction over such matters. If the maturity of this Note is accelerated by reason of an election by the holder hereof resulting from an Event of Default, voluntary prepayment by the Borrowers or otherwise, then earned interest may never include more than the maximum amount permitted by law, statute, rule or regulation, computed from the date hereof until payment, and any interest in excess of the maximum amount permitted by law, statute, rule or regulation shall be canceled automatically and, if theretofore paid, shall at the option of the holder hereof either be rebated to the Borrowers or credited on the principal amount of this Note, or if this Note has been paid, then the excess shall be rebated to the Borrowers. The aggregate of all interest (whether designated as interest, service charges, points or otherwise) contracted for, chargeable, or receivable under this Note shall under no circumstances exceed the maximum legal rate upon the unpaid principal balance of this Note remaining unpaid from time to time. If such interest does exceed the maximum legal rate, it shall be deemed a mistake and such excess shall be canceled automatically and, if theretofore paid, rebated to the Borrowers or credited on the principal amount of this Note, or if this Note has been repaid, then such excess shall be rebated to the Borrowers.

10. Construction. The undersigned and the original holder of this Note have participated jointly in the negotiation and drafting of this Note. In the event an ambiguity or question of intent or interpretation arises, this Note shall be construed as if drafted jointly by the undersigned and the original holder of this Note, 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 Note.

11. Governing Law. This ^.Note shall be governed and construed in accordance with the domestic laws of the State of Missouri, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Missouri or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Missouri.

12. Replacement. Upon receipt of evidence reasonably satisfactory to the Borrowers (an affidavit of the holder of this Note shall be satisfactory) of the ownership and the loss, theft, destruction or mutilation of this Note, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Borrowers (provided, that if the holder of this Note is a financial institution or other institutional investor its own agreement shall be satisfactory), or, in the case of any such mutilation upon surrender of this Note, the Borrowers shall (at their expense) execute and deliver, in lieu thereof, a new Note of like kind representing the same rights represented by such lost, stolen, destroyed or mutilated Note and dated the date of such lost, stolen, destroyed or mutilated Note.

13. Notices. Except as otherwise expressly provided herein, all notices referred to in this Note shall be in writing and shall be delivered personally, sent by reputable overnight courier service (charges prepaid) or sent by registered or certified mail, return receipt requested, postage prepaid and

shall be deemed to have been given when so delivered, sent or deposited in the U.S. Mail (i) to the Borrowers, at their principal executive offices and (ii) to the holder of this Note, at such holder’s address as it appears in the records of the Borrowers (unless otherwise indicated in writing by any such holder).

14. Certain Waivers . Each party executing this Note hereby waives diligence, presentment, protest and demand and notice of protest and demand, dishonor and nonpayment of this Note, and expressly agrees that this Note, or any payment hereunder, may be extended from time to time and that the holder hereof may accept security for this Note or release security for this Note, all without in any way affecting the liability of the undersigned for all obligations and liabilities under this Note.

Notice Required by Section 432.047 R.S. Mo.: “ORAL AGREEMENTS OR COMMITMENTS TO LOAN MONEY, EXTEND CREDIT OR TO FORBEAR FROM ENFORCING REPAYMENT OF A DEBT INCLUDING PROMISES TO EXTEND OR RENEW SUCH DEBT ARE NOT ENFORCEABLE, REGARDLESS OF THE LEGAL THEORY UPON WHICH IT IS BASED THAT IS IN ANY WAY RELATED TO THE CREDIT AGREEMENT. TO PROTECT YOU (BORROWER(S)) AND US (CREDITOR) FROM MISUNDERSTANDING OR DISAPPOINTMENT, ANY AGREEMENTS WE REACH COVERING SUCH MATTERS ARE CONTAINED IN THIS WRITING, WHICH IS THE COMPLETE AND EXCLUSIVE STATEMENT OF THE AGREEMENT BETWEEN US, EXCEPT AS WE MAY LATER AGREE IN WRITING TO MODIFY IT.”

The Company shall register the transfer of any portion of this Warrant in the Warrant Register, upon surrender of this Warrant, with the Form of Assignment attached hereto duly completed and signed, to the Company at its address specified herein. Upon any such registration or transfer, a new Warrant to purchase Common Stock, in substantially the form of this Warrant (any such new Warrant, a "New Warrant"), evidencing the portion of this Warrant so transferred shall be issued to the transferee and a New Warrant evidencing the remaining portion of this

Warrant not so transferred, if any, shall be issued to the transferring Holder. The acceptance of the New Warrant by the transferee thereof shall be deemed the acceptance by such transferee of all of the rights and obligations of a holder of a Warrant.

4. Exercise and Duration of Warrants. This Warrant shall be exercisable by the registered Holder at any time and from time to time on or after the date hereof to and including the Expiration Date. At 5:00 p.m., St. Louis, Missouri time on the Expiration Date, the portion of this Warrant not exercised prior thereto shall be and become void and of no value, provided, that if the last reported sales price of the Common Stock as reported on the principal trading market on which the Common Stock is then quoted, immediately prior to the close of business on the Expiration Date is greater than the Exercise Price on the Expiration Date, then this Warrant shall be deemed to have been exercised in full (to the extent not previously exercised) on a “cashless exercise” basis at 5:00 p.m. St. Louis, Missouri time on the Expiration Date. The Company may not call or redeem all or any portion of this Warrant without the prior written consent of the Holder.

5. Delivery of Warrant Shares.

(a) To effect exercises hereunder, the Holder shall not be required to physically surrender this Warrant unless the aggregate Warrant Shares represented by this Warrant is being exercised. Upon delivery of the Exercise Notice to the Company (with the attached Warrant Shares Exercise Log) at its address for notice set forth herein and upon payment of the Exercise Price multiplied by the number of Warrant Shares that the Holder intends to purchase hereunder, the Company shall promptly issue and deliver to the Holder, a certificate for the Warrant Shares issuable upon such exercise. A "Date of Exercise" means the date on which the Holder shall have delivered to Company: (i) the Exercise Notice (with the Warrant Exercise Log attached to it), appropriately completed and duly signed and (ii) if such Holder is not utilizing the cashless exercise provisions set forth in this Warrant, payment of the Exercise Price for the number of Warrant Shares so indicated by the Holder to be purchased.

(b) The Company's obligations to issue and deliver Warrant Shares in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation of law by the Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the Holder in connection with the issuance of Warrant Shares. Nothing herein shall limit a Holder's right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company's failure to timely deliver certificates representing shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.

6. Charges, Taxes and Expenses. Issuance and delivery of certificates for shares of Common Stock upon exercise of this Warrant shall be made without charge to the Holder for any issue or transfer tax, withholding tax, transfer agent fee or other incidental tax or expense in respect of the issuance of such certificates, all of which taxes and expenses shall be paid by the Company; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the registration of any certificates for Warrant Shares or Warrants in a name other than that of the Holder. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof.

7. Replacement of Warrant. If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity (which may include a surety bond for any Holder other than the original Holder of the Warrant), if requested. Applicants for a New Warrant under such circumstances shall also comply with such other reasonable regulations and procedures and pay such other reasonable third party costs as the Company may prescribe. If a New Warrant is requested as a result of a mutilation of this Warrant, then the Holder shall deliver such mutilated Warrant to the Company as a condition precedent to the Company’s obligation to issue the New Warrant.

8. Reservation of Warrant Shares. The Company covenants that it will at all times reserve and keep available out of the aggregate of its authorized but unissued and otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Warrant Shares upon exercise of this Warrant as herein provided, the number of Warrant Shares which are then issuable and deliverable upon the exercise of this entire Warrant, free from preemptive rights or any other contingent purchase rights of persons other than the Holder (taking into account the adjustments and restrictions of Section 9). The Company covenants that all Warrant Shares so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, be duly and validly authorized, issued and fully paid and nonassessable.

9. Certain Adjustments. The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 9.

(a) Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding, (i) pays a stock dividend on its Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides outstanding shares of Common Stock into a larger number of shares, or (iii) combines outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment under this paragraph occurs during the period that an Exercise Price is calculated hereunder, then the calculation of such Exercise Price shall be adjusted appropriately to reflect such event.

(b) Pro Rata Distributions. If the Company, at any time while this Warrant is outstanding, distributes to all holders of Common Stock (i) evidences of its indebtedness, (ii) any security (other than a distribution of Common Stock covered by the preceding paragraph), (iii) rights or warrants to subscribe for or purchase any security, or (iv) any other asset (in each case, "Distributed Property"), then, at the request of any Holder delivered before the 90th day after the record date fixed for determination of shareholders entitled to receive such distribution, the Company will deliver to such Holder, promptly after such request (or, if later, on the effective date of such distribution), the Distributed Property that such Holder would have been entitled to receive in respect of the Warrant Shares for which such Holder's Warrant could have been exercised immediately prior to such record date. If such Distributed Property is not delivered to a Holder pursuant to the preceding sentence, then upon any exercise of the Warrant that occurs after such record date, such Holder shall be entitled to receive, in addition to the Warrant Shares otherwise issuable upon such conversion, the Distributed Property that

such Holder would have been entitled to receive in respect of such number of Warrant Shares had the Holder been the record holder of such Warrant Shares immediately prior to such record date. Notwithstanding the foregoing, this Section 9(b) shall not apply to any distribution of rights or securities in respect of adoption by the Company of a shareholder rights plan which events shall be covered by the anti-dilution provisions of Section 9(a).

(c) Fundamental Transactions. If, at any time while this Warrant is outstanding, (1) the Company effects any merger or consolidation of the Company with or into another Person, (2) the Company effects any sale of all or substantially all of its assets in one or a series of related transactions, (3) any tender offer or exchange offer approved or authorized by the Board of Directors of the Company (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or property, or (4) the Company effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (in any such case, a "Fundamental Transaction"), then the Holder shall have the right thereafter to receive, upon exercise of this Warrant, the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of Warrant Shares then issuable upon exercise in full of this Warrant (the "Alternate Consideration"). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. At the Holder's request, any successor to the Company or surviving entity in such Fundamental Transaction shall issue to the Holder a new warrant substantially in the form of this Warrant and consistent with the foregoing provisions and evidencing the Holder's right to purchase the Alternate Consideration for the aggregate Exercise Price upon exercise thereof. The terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this paragraph (c) and insuring that the Warrant (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.

(d) Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to paragraph (a) of this Section, the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment.

(e) Calculations. All calculations under this Section 9 shall be made to the nearest cent or the nearest 1/100^th of a share, as applicable.

(f) Notice of Adjustments. Upon the occurrence of each adjustment pursuant to this Section 9, the Company at its expense will promptly compute such adjustment in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment, including a statement of the adjusted Exercise Price and adjusted number or type of Warrant Shares or other securities issuable upon exercise of this Warrant (as applicable), describing the transactions giving rise to such adjustments and showing in detail the facts upon which such adjustment is based. Upon written request, the Company will promptly deliver a copy of each such certificate to the Holder and to the Company's transfer agent.

(g) Notice of Corporate Events. If the Company (i) declares a dividend or any other distribution of cash, securities or other property in respect of its Common Stock, including without limitation any granting of rights or warrants to subscribe for or purchase any capital stock of the Company or any Subsidiary, (ii) authorizes or approves, enters into any agreement contemplating or solicits shareholder approval for any Fundamental Transaction or (iii) authorizes the voluntary dissolution, liquidation or winding up of the affairs of the Company, then the Company shall deliver to the Holder a notice describing the material terms and conditions of such transaction, at least 20 calendar days prior to the applicable record or effective date on which a Person would need to hold Common Stock in order to participate in or vote with respect to such transaction, and the Company will take all steps reasonably necessary in order to insure that the Holder is given the practical opportunity to exercise this Warrant prior to such time so as to participate in or vote with respect to such transaction; provided, however, that the failure to deliver such notice or any defect therein shall not affect the validity of the corporate action required to be described in such notice.

10. Payment of Exercise Price. The Holder may pay the Exercise Price in one of the following manners:

(a) Cash Exercise. The Holder may deliver immediately available funds; or

(b) Cashless Exercise. The Holder may notify the Company in an Exercise Notice of its election to utilize cashless exercise, in which event the Company shall issue to the Holder the number of Warrant Shares determined as follows:

X = Y [(A-B)/A]

where:

X = the number of Warrant Shares to be issued to the Holder.

Y = the number of Warrant Shares with respect to which this Warrant is being exercised.

A = the average of the closing prices for the five Trading Days immediately prior to (but not including) the Exercise Date.

B = the Exercise Price.

For purposes of Rule 144 promulgated under the Securities Act, it is intended, understood and acknowledged that the Warrant Shares issued in a cashless exercise transaction shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced, on the date this Warrant was originally issued.

As used herein, “Trading Day” shall mean a day on which the principal market on which the Company’s stock is listed or quoted, as the case may be, is open for trading.

11. No Fractional Shares. No fractional shares of Warrant Shares will be issued in connection with any exercise of this Warrant. In lieu of any fractional shares which would, otherwise be issuable, the Company shall pay cash equal to the product of such fraction multiplied by the closing price of one Warrant Share as reported by the applicable Trading Market on the date of exercise.

12. Notices. Any and all notices or other communications or deliveries hereunder (including, without limitation, any Exercise Notice) shall be in writing and shall be deemed given and effective on

the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number specified in this Section prior to 5:00 p.m. (St. Louis, Missouri time) on a Trading Day, (ii) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number specified in this Section on a day that is not a Trading Day or later than 5:00 p.m. (St. Louis, Missouri time) on any Trading Day, (iii) the Trading Day following the date of mailing, if sent by nationally recognized overnight courier service, or (iv) upon actual receipt by the party to whom such notice is required to be given. The addresses for such communications shall be: (i) if to the Company, to Siboney Corporation, attention: Chief Financial Officer, ▇▇▇ ▇. ▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇. ▇▇▇▇▇, ▇▇▇▇▇▇▇▇, Facsimile No.: (▇▇▇) ▇▇▇-▇▇▇▇, or (ii) if to the Holder, to the address or facsimile number appearing on the Warrant Register or such other address or facsimile number as the Holder may provide to the Company in accordance with this Section.

13. Warrant Agent. The Company shall serve as warrant agent under this Warrant. Upon at least 30 days' notice to the Holder, the Company may appoint a new warrant agent. Any corporation into which the Company or any new warrant agent may be merged or any corporation resulting from any consolidation to which the Company or any new warrant agent shall be a party or any corporation to which the Company or any new warrant agent transfers substantially all of its corporate trust or shareholders services business shall be a successor warrant agent under this Warrant without any further act. Any such successor warrant agent shall promptly cause notice of its succession as warrant agent to be mailed (by first class mail, postage prepaid) to the Holder at the Holder's last address as shown on the Warrant Register.

14. Miscellaneous.

(a) This Warrant shall be binding on and inure to the benefit of the parties hereto and their respective successors and assigns. Subject to the preceding sentence, nothing in this Warrant shall be construed to give to any Person other than the Company and the Holder any legal or equitable right, remedy or cause of action under this Warrant. This Warrant may be amended only in writing signed by the Company and the Holder and their successors and assigns.

(b) All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be governed by and construed and enforced in accordance with the internal laws of the State of Missouri, without regard to the principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of this Warrant and the transactions herein contemplated (“Proceedings”) (whether brought against a party hereto or its respective Affiliates, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the St. Louis, Missouri (the “Missouri Courts”). Each party hereto hereby irrevocably submits to the exclusive jurisdiction of the Missouri Courts for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any Proceeding, any claim that it is not personally subject to the jurisdiction of any Missouri Court, or that such Proceeding has been commenced in an improper or inconvenient forum. Each party hereto hereby irrevocably waives personal service of process and consents to process being served in any such Proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Warrant and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Each party hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Warrant or the transactions contemplated hereby. If either party shall commence a Proceeding to enforce any provisions of this Warrant, then the prevailing party in such Proceeding shall

be reimbursed by the other party for its attorney’s fees and other costs and expenses incurred with the investigation, preparation and prosecution of such Proceeding.

(c) The headings herein are for convenience only, do not constitute a part of this Warrant and shall not be deemed to limit or affect any of the provisions hereof.

(d) In case any one or more of the provisions of this Warrant shall be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Warrant shall not in any way be affected or impaired thereby and the parties will attempt in good faith to agree upon a valid and enforceable provision which shall be a commercially reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Warrant.
