AND IT IS HEREBY AGREED AND DECLARED as follows:-

from the date of that demand until receipt of that amount in full by the Bank in accordance with the following provisions:-
|-- | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

to exist.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

|3. | In the event that payment by the Guarantor hereunder in respect of interest payable by the Borrower (whether pursuant to paragraph (f) above or Clause l) would or might attract a liability to tax in the hands of
the Bank, even though such interest, if paid by the Borrower, would have been tax free, then, the obligations of the Guarantor in respect of such interest shall be to pay the amount thereof together with such additional amount as the Bank shall
certify to be necessary to compensate for any taxation payable or chargeable on such interest by or against the Bank and all references to interest in this Guarantee and Indemnity shall be construed accordingly.
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (d) | vote for or against any composition offered or made by the Borrower or any of the said person or company in any winding up, bankruptcy or arrangement matter whether outside or under the control of the Court, and value
or give up therein any security;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | in the case of credits or facilities provided for two or more purposes of a different character vary the proportions of the respective credits allocated or applied for different purposes;

| | --- | -------------------------------------------------------------------------------------------------------------

|5. | This Guarantee and Indemnity shall be a continuing security and shall remain in force until determined by three months written notice actually received by the Bank from the Guarantor but such determination shall not
affect the Guarantors liability in respect of the Borrowers liabilities to the Bank at the date when the determination takes effect (including any new or additional liability incurred by the Borrower after receipt of the notice by the
Bank but prior to its expiration).
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|6. | This Guarantee and Indemnity shall apply to and secure any ultimate balance owing by the Borrower to the Bank and until this Guarantee and Indemnity has been determined and such balance has been paid in full

|7. | The Guarantor hereby warrants that the Guarantor has not and hereby covenants that it will not in respect of any sums hereby secured take from the Borrower either directly or indirectly without the prior written consent
of the Bank, any promissory note, bill of exchange, mortgage, charge or other counter-security whether merely personal or involving a charge on any property whatsoever of the Borrower whereby the Guarantor or
any person claiming through it by endorsement, assignment or otherwise would or might on the liquidation, dissolution or bankruptcy of the Borrower and to the prejudice of the Bank increase the proofs in such liquidation, dissolution or bankruptcy
or diminish the assets distributable among the creditors of the Borrower. As regards any such counter-security as aforesaid which the Guarantor may have taken or may take with such consent as aforesaid, such counter-security shall be held on trust for the Bank and shall be a security to the Bank for the fulfilment of the obligations of the Guarantor hereunder and shall be forthwith deposited by the Guarantor with the
Bank for that purpose and the Guarantor shall account to the Bank for all moneys at any time received by the Guarantor in respect thereof.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|8. | In addition to any other lien, right of set-off or other right to which the Bank may at any time be entitled (whether by agreement, operation of law or otherwise) (a) the
Bank shall in respect of the Guarantors liability hereunder have a lien on all securities documents or other property of the Guarantor at any time held by the Bank whether for safe custody, collection or otherwise; and (b) the Bank may at
any time (both before and after any demand hereunder and without prior notice) set off any liability of the Borrower to the Bank (whether or not then due and payable) against any credit balance in any account(s) of the Guarantor with any office of
the Bank (whether current or otherwise or subject to notice or not) and (c) may retain the whole or any part of such credit balance to meet the liability of the Guarantor to the Bank.
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|9. | If this Guarantee and Indemnity is determined or a demand is made by the Bank hereunder or in the event of this Guarantee and Indemnity ceasing from any cause whatsoever to be binding as a continuing security on the
Guarantor or its successors, the Bank shall be at liberty without thereby affecting its rights hereunder to open a fresh account or accounts and to continue any then existing account or accounts with the Borrower and no moneys paid into any such
account or accounts by or on behalf of the Borrower and subsequently drawn out shall on settlement of any claim in respect of this Guarantee and Indemnity be appropriated or applicable in or towards or have the effect of payment of any part of the
moneys due from the Borrower at the time of this Guarantee and Indemnity ceasing to be so binding unless the person or company paying in such monies shall at the time of such payment in writing direct the Bank specially so to appropriate the same.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|10. | This Guarantee and Indemnity shall be construed and take effect as a guarantee and indemnity of and in respect of the whole and every part of the principal moneys and other moneys hereby secured and accordingly the
Guarantor shall not be entitled as against the Bank to any right of proof in the liquidation, insolvency or bankruptcy of the Borrower or other right of a surety discharging his liability in respect of the principal debt unless and until the whole
of the principal moneys and other moneys hereby secured shall have first been completely discharged and satisfied AND further for the purpose of enabling the Bank to sue the Borrower or prove against its estate for the whole of the moneys secured as
aforesaid or to preserve intact the liability of any other party the Bank may at any time place and keep for such time as it may think prudent any money received, recovered or realised on foot of this Guarantee and Indemnity to and at a separate or
suspense account to the credit either of the Guarantor or such other person or persons or transactions (if any) as the Bank shall think fit without any intermediate obligation on the part of the Bank to apply the same or any part thereof in or
towards discharge of the moneys hereby secured or any intermediate right on the part of the Guarantor to sue the Borrower or prove against his estate in the bankruptcy, insolvency or liquidation of the Borrower in competition with or so as to
diminish any dividend or other advantage that would or might come to the Bank or to treat the liability of the Guarantor as diminished.

|11. | (a) | This Guarantee and Indemnity shall not be discharged nor shall the Guarantors liability be affected by reason of :-
|--- | --- | --------------------------------------------------------------------------------------------------------------------



| | (i) | the death or other disability or any change in the constitution of the Borrower or any failure of or irregularity defect or informality in any security given by or on behalf of the Borrower or any other person or
company in respect of all or any of the liabilities hereby guaranteed nor by any legal limitation, disability, incapacity or want of any borrowing powers of or by the Borrower or want of authority of any director, manager, official or other person
appearing to be acting for the Borrower in any matter in respect of those liabilities.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (b) | The liability of the Guarantor hereunder shall be as a sole or primary obligor and not merely as surety and shall not be impaired or discharged by reason of any matter act or omission whereby the liability of such
Guarantor would not have been discharged if it had been a principal Borrower and the Guarantor hereby waives all and any of its rights as surety which may at any time be inconsistent with any of the provisions of these presents.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|12. | In addition to the guarantee contained herein and separate therefrom the Guarantor hereby irrevocably agrees to keep the Bank fully and effectively indemnified from and against all costs, claims, charges, damages,
expenses and losses whatsoever arising out of or in connection with any transactions entered into by the Bank with the Borrower as hereinbefore specified or as a result of any disability, incapacity, irregularity, defect or informality specified in
Clause 11(a).
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|13. | (a) | This Guarantee and Indemnity shall not be discharged nor shall the Guarantors liability be affected by any amalgamation or merger of
the Bank with any other company or any reconstruction of the Bank. Accordingly this Guarantee and Indemnity shall remain in full force and effect in favour of any company succeeding to the Banks rights as a result of any such amalgamation,
merger or reconstruction.
|--- | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

| | (b) | In the case where the Borrower is a partnership or firm this Guarantee and Indemnity shall apply to all moneys borrowed and liabilities incurred whether actual or contingent in the partnerships or firms name
until receipt by the Bank of actual notice of the dissolution or reconstitution of the partnership or firm. If, however, the dissolution or reconstitution be by reason only of the retirement or death of a partner or the introduction of a new partner
or partners this Guarantee and Indemnity shall continue and apply to all moneys and liabilities incurred by or due to the Bank from the new partnership or firm thereby constituted as though there had been no change in the partnership or firm as
previously constituted.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | If the Guarantor or the Borrower is a company this Guarantee and Indemnity shall continue to be binding and effective as a continuing security notwithstanding the liquidation, absorption, amalgamation or reconstruction

respectively of the Companies Act, 1990 or equivalent or analogous legislation in any other jurisdiction or any statutory modification or re-enactment thereof and no release settlement or discharge, which may
have been given or made on the faith of any such assurance, security or payment shall prejudice or affect the Banks right to recover from the Guarantor to the full extent of this Guarantee and Indemnity or the Banks right to exercise the
rights under Clause 8 (b) and (c) hereof.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|15. | The liquidation, insolvency or dissolution of the Borrower shall not affect or determine the Guarantors liability hereunder but such liability shall continue in full force and effect until the Bank shall have been
repaid all moneys due to the Bank from the Borrower immediately before the liquidation, insolvency or dissolution of the Borrower together with interest thereon.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|16. | The Bank shall be at liberty but not bound to resort for its own benefit to any other means of payment at any time and in any order it thinks fit without thereby diminishing the Guarantors liability hereunder and
the Bank may put this Guarantee and Indemnity in force either for the payment of the ultimate balance (together with interest thereon) after resorting to other means of payment or for the balance due at any time notwithstanding that other means of
payment have not been resorted to and in the latter case without entitling the Guarantor to any benefit from such other means of payment so long as any moneys remain due to the Bank from the Borrower.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|17. | Any indebtedness of the Borrower now or hereafter held by the Guarantor is hereby subordinated to the indebtedness of the Borrower to the Bank and such indebtedness of the Borrower to the Guarantor if and only if the
Bank so require shall be collected enforced and received by the Guarantor as trustee for the Bank and be paid over to the Bank on account of the indebtedness of the Borrower to the Bank but without reducing or affecting in any manner the
Guarantors liability under the provisions of this Guarantee and Indemnity.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|18. | (a) | The moneys hereby guaranteed shall be due and payable to the Bank in the currency in which the moneys due to the Bank by the Borrower are
denominated (the denominated currency), but without prejudice to this, if a
|--- | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

| | payment is made by the Guarantor in a currency other than the denominated currency (the different currency) then, the Guarantors obligations to the Bank will only be satisfied
to the extent that the Bank may in accordance with normal banking procedures, on the business day following receipt of the different currency purchase in the appropriate Foreign Exchange Market, the denominated currency and if at the date of such
purchase, the denominated currency so purchased falls short of the amount originally due to the Bank in the denominated currency, the Guarantor agrees as a separate obligation, to indemnify the Bank against any such shortfall.
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | In the event that the amount of the denominated currency is or has been calculated by reference to another currency (the base currency) the Guarantors obligation hereunder is to repay the full amount
outstanding in the denominated currency even if due to fluctuations in the appropriate Foreign Exchange Market the amount of the denominated currency if reconverted at the date of demand hereunder in to the base currency would exceed the monetary
limit in respect of principal hereby guaranteed.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Any amounts which the Bank recovers under any judgement of any Court against the Guarantor in respect of the Guarantors liabilities hereunder shall as soon as is reasonably practicable be converted by the Bank (if
necessary) into the currency or currencies of denomination of those liabilities for which such judgement was obtained. Should the proceeds of any such conversion produce amounts less than the amounts of those liabilities but the judgement has been
wholly satisfied, then as a separate obligation (which shall not merge in the judgement) the Guarantor shall be liable to the Bank for the amount of any such deficiency. If the proceeds of any such conversion produce amounts in excess of the
respective amounts of those liabilities then, notwithstanding any judgement as aforesaid, the Bank shall hold such excess to the Guarantors order.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | This Guarantee and Indemnity and the Banks rights under it shall not be affected or prejudiced by the Bank permitting the Borrower to convert and/or reconvert any facility denominated in one currency into another
currency or currencies.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|19. | All sums payable by the Guarantor hereunder shall be paid in full without any deductions, set off, counterclaim or withholding whatsoever and without any deduction for or on account of any present or future taxes,
levies, imposts, duties, deductions or withholding or other charges of whatever nature imposed, levied, collected, withheld or assessed unless the Guarantor is compelled by law so to do. If the Guarantor shall be so compelled then the Guarantor
shall ensure that such deduction or withholding will not exceed the minimum legal liability therefor and shall forthwith pay to the Bank such additional amounts as may be necessary in respect of its obligations hereunder in order that the net
amounts received by the Bank after such taxes, levies, imposts, duties, deductions, withholdings or other charges shall equal the amounts due hereunder.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|20. | A certificate in writing signed by any officer of the Bank as to any rate of interest applicable hereunder and the amount of the liabilities of the Borrower to the Bank or the total amount recoverable under this
Guarantee and Indemnity shall be conclusive evidence for all purposes against the Guarantor, except in case of manifest error.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

|21. | The liability of any Guarantor hereunder shall not be affected by any failure by the Bank to take any security or by any invalidity of any security taken or by any existing or future agreement by the Bank as to the
application of any advances made or to be made to the Borrower nor by the fact that this Guarantee and Indemnity is or may not be binding on any other Guarantor hereunder for any reason whatever.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|22. | This Guarantee and Indemnity shall be additional to any other guarantee or security at any time held from the Guarantor or any other person or company in respect of all or any of the liabilities hereby guaranteed.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|23. | Without prejudice to any other provision hereof the Bank shall be at liberty from time to time to enter, without the consent of the other or others of the Guarantors, into any arrangement with any one or more of the
Guarantors for the discharge of its or their liability hereunder on any terms that the Bank may think fit, and any such discharge of the one or more of the Guarantors shall leave the liability of the other or others of the Guarantors unaffected and
as effective as if such other as sole Guarantor or such others as joint and several Guarantors had alone signed this document.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|24. | If at any time any one or more of the provisions of this Guarantee and Indemnity is or becomes invalid, illegal or unenforceable in any jurisdiction in any respect, the validity, legality and enforceability of the
remaining provisions hereof shall not in any way be affected or impaired thereby.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|25. | No delay by the Bank in exercising or the omission by the Bank to exercise any right, power or privilege shall impair such right, power or privilege or be construed as a waiver of such right, power or privilege nor
shall any single or partial exercise of any right, power or privilege preclude any further exercise thereof or the exercise of any other right power or privilege. The rights and remedies herein provided are cumulative and not exclusive of any rights
or remedies provided by law or otherwise.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

and where the Borrower is a firm shall include the person(s) from time to time constituting the firm whether or not under the same style or firm name.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|28. | If the Borrower be a committee or association or other unincorporated body which has no legal existence or which is under no legal liability to discharge obligations undertaken or purported to be undertaken by it or on
its behalf this Guarantee and Indemnity shall be valid and binding upon the Guarantor notwithstanding that fact and as though the Guarantor was the principal Borrower or if there be more than one Guarantor as though the Guarantors were joint and
several principal Borrowers.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
