ARRANGEMENT AGREEMENT

Section 2.01 Arrangement Agreement

This Plan of Arrangement is made pursuant to, and is subject to the provisions of, the Arrangement Agreement, except in respect of the sequence of the steps comprising the Arrangement, which shall occur in the order set forth herein.

ARTICLE THREE

ARRANGEMENT

Section 3.01 Arrangement

At the Effective Time, the following, other than Section 3.01(j), shall occur and shall be deemed to occur sequentially in the following order without any further act or formality:

(a)

each Creston Share held by a Dissenting Shareholder shall be deemed to be transferred by the holder thereof, without any further act or formality on its part, free and clear of all

liens, claims and encumbrances, to Mercator and Mercator shall thereupon be obliged to pay the amount therefor determined and payable in accordance with Article 4 hereof, and the name of such holder shall be removed from the central securities register of Creston as a holder of Creston Shares and Mercator shall be recorded as the registered holder of the Creston Shares so transferred and shall be deemed to be the legal and beneficial owner of such Creston Shares;

(b)

each Creston Share (other than a Creston Share held by a Dissenting Shareholder or a Creston Share held by Mercator or any subsidiary of Mercator) shall be deemed to be transferred to Mercator and, in consideration therefor, Mercator shall issue and pay the Consideration for each Creston Share to the former holder of such Creston Share, subject to Sections 3.03, 3.04 and Article 5 hereof;

(c)

(i) in accordance with the Creston Stock Option Plan, each holder of a Creston Option outstanding immediately prior to the Effective Time shall receive (and such holder shall accept), upon the exercise of such holder’s Creston Option, in lieu of each Creston Share to which such holder was theretofore entitled, upon such exercise and for the same aggregate consideration payable therefor, such number of Mercator Shares which is equal to the sum of (A) 0.15 of a Mercator Share, and (B) the quotient obtained by dividing $0.08 by the Mercator Share Value, provided however that in no event will the number of Mercator Shares issuable pursuant to this Section 3.01(c), together with the number of Mercator Shares issuable pursuant to Sections 3.01(b) and 3.01(d) exceed 50,174,951 and if the number of Mercator Shares issuable pursuant to this Section 3.01(c), together with the number of Mercator Shares issuable pursuant to Sections 3.01(b) and 3.01(d) would otherwise exceed 50,174,951, the number of Mercator Shares to be issued as contemplated in clause (B) of this Section 3.01(c) will be reduced, pro rata for all Creston Options, so that such maximum number will not be exceeded; and (ii) each such Creston Option shall continue to be governed by and be subject to the terms of the Creston Stock Option Plan and any applicable agreement thereunder. If the adjustment to the Creston Options contemplated by this paragraph results in a disposition of Creston Options for options to acquire Mercator Shares or “new” Creston Options, it is intended that the provisions of subsection 7(1.4) of the Tax Act apply to any such disposition and that the Mercator Option In-The-Money Amount in respect of the Creston Options not exceed the Creston Option In-The-Money Amount in respect of the Creston Options. Therefore, in the event that Mercator and the holder of any Creston Options agree that the Mercator Option In-The-Money Amount in respect of a Creston Option exceeds the Creston Option In-The-Money Amount in respect of the Creston Option, the number of Mercator Shares which may be acquired on exercise of the Creston Option at and after the Effective Time will be adjusted accordingly with effect at and from the Effective Time to ensure that the Mercator Option In-The-Money Amount in respect of the Creston Option does not exceed the Creston Option In-The-Money Amount in respect of the Creston Option and the ratio of the amount payable to acquire such shares to the value of such shares to be acquired shall be unchanged;

(d)

(i) in accordance with the certificate, indenture or documentation governing the terms and conditions of the Creston Warrants, each holder of a Creston Warrant outstanding immediately prior to the Effective Time shall be entitled to receive (and such holder shall accept), upon the exercise of such holder’s Creston Warrants, in lieu of each Creston Share to which such holder was theretofore entitled, upon such exercise and for the same aggregate consideration payable therefore, the Consideration. The payment of the exercise price of a Creston Warrant will be satisfied, in whole or in part, by setting off the

Cash Consideration payable to the holder against an equivalent portion of the exercise price payable by the holder such that, at any time from and after the Effective Time, upon exercise of a Creston Warrant the holder (A) will be required to deliver in satisfaction of the exercise price an amount of cash equal to the amount, if any, by which the exercise price exceeds the amount of the Cash Consideration, and (B) will receive the Share Consideration; and (ii) each such Creston Warrant shall continue to be governed by and be subject to the terms of the certificate, indenture or documentation governing the terms and conditions of the Creston Warrants;

(e)

each Creston Share held by Mercator including the Creston Shares acquired pursuant to Sections 3.01(a) and (b) hereof shall be transferred to Subco in consideration of the issue by Subco to Mercator of one common share of Subco for each Creston Share so transferred;

(f)

the stated capital in respect of the Creston Shares shall be reduced to $1.00 without any repayment of capital in respect thereof;

(g)

Creston shall file an election with the CRA, to be effective prior to the amalgamation described in Section 3.01(h) hereof, to cease to be a public corporation for the purposes of the Tax Act;

(h)

Creston and Subco shall amalgamate to form one corporate entity ("Amalco") under the provisions of Part 9, Division 3 of the BCBCA;

(i)

from and after the Effective Date, at the time of the step contemplated in Section 3.01(h):

(i)

Amalco will own and hold all of the property of Creston and Subco and, without limiting the provisions hereof, all rights of creditors or others will be unimpaired by such amalgamation, and all liabilities and obligations of Creston and Subco, whether arising by contract or otherwise, may be enforced against Amalco to the same extent as if such liabilities and obligations had been incurred or contracted by it;

(ii)

Amalco will be liable for all of the liabilities and obligations of Creston and Subco;

(iii)

all rights, contracts, permits and interests of Creston and Subco will be rights, contracts, permits and interests of Amalco as if Creston and Subco continued and, for greater certainty, the amalgamation will not constitute a transfer or assignment of the rights or obligations of either of Creston or Subco under any such rights, contracts, permits and interests;

(iv)

any existing cause of action, claim or liability to prosecution will be unaffected;

(v)

any civil, criminal or administrative action or proceeding pending by or against either Subco or Creston will be continued by or against Amalco;

(vi)

a conviction against, or ruling, order or judgment in favour of or against either Subco or Creston may be enforced by or against Amalco;

(vii)

Mercator shall receive on the amalgamation one Amalco common share in exchange for each Subco common share previously held and all of the issued and outstanding Creston Shares will be cancelled without any repayment of capital in respect thereof;

(viii)

the name of Amalco shall be the name agreed upon between Mercator and Creston prior to the Effective Date and its registered office shall be located at ▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇;

(ix)

Amalco shall be authorized to issue an unlimited number of common shares without par value;

(x)

there shall be no restriction on the business which Amalco is authorized to carry on or on the powers which Amalco may exercise;

(xi)

the notice of articles of Amalco shall be substantially in the form attached as Appendix I to this Plan of Arrangement;

(xii)

the articles of Amalco shall be substantially in the form attached as Appendix II to this Plan of Arrangement;

(xiii)

the first directors of Amalco following the amalgamation shall be ▇▇▇▇▇ ▇▇▇▇▇▇ and ▇▇▇▇ ▇▇▇▇▇▇▇ or such other persons as may be agreed upon between Mercator and Creston prior to the Effective Date;

(xiv)

the stated capital of the common shares of Amalco will be an amount equal to the paid up capital, as that term is defined in the Tax Act, attributable to the common shares of Subco immediately prior to the amalgamation; and

(j)

The steps referred to in this Section 3.01 shall be deemed to constitute a "reclassification" or "change" of the Creston Shares, including for the purposes of the certificates, indentures or documentation governing the terms and conditions of the Creston Warrants.

Section 3.02 Effective Time Procedures

Following the receipt of the Final Order and prior to the Effective Date, Mercator shall deliver or arrange to be delivered to the Depositary certificates representing the Mercator Shares required to be issued to Former Creston Shareholders and the requisite Cash Consideration required to be paid to Former Creston Shareholders in accordance with the provisions of Section 3.01 hereof, which certificates and Cash Consideration shall be held by the Depositary as agent and nominee for such Former Creston Shareholders for distribution to such Former Creston Shareholders in accordance with the provisions of Article 5 hereof.

Subject to the provisions of Article 5 hereof, and upon return of a properly completed letter of transmittal by a registered Former Creston Shareholder together with certificates representing Creston Shares and such other documents as the Depositary may require, Former Creston Shareholders shall be entitled to receive delivery of certificates representing the Mercator Shares and a cheque for the Cash Consideration to which they are entitled pursuant to Section 3.01(b) hereof.

An Eligible Holder whose Creston Shares are exchanged for the Consideration pursuant to the Arrangement shall be entitled to make a joint income tax election, pursuant to section 85 of the Tax Act

(and any analogous provision of provincial income tax law) (a "Section 85 Election") with respect to the exchange by providing two signed copies of the necessary joint election forms to an appointed representative, as directed by Mercator, within 90 days after the Effective Date, duly completed with the details of the number of Creston Shares transferred and the applicable agreed amounts for the purposes of such joint elections. Mercator shall, within 90 days after receiving the completed joint election forms from an Eligible Holder, and subject to such joint election forms being correct and complete and in compliance with requirements imposed under the Tax Act (or applicable provincial income tax law), sign and return them to the Eligible Holder for filing with the CRA (or the applicable provincial tax authority). Neither Creston, Mercator nor any successor corporation shall be responsible for the proper completion of any joint election form nor, except for the obligation to sign and return duly completed joint election forms which are received within 90 days of the Effective Date, for any taxes, interest or penalties resulting from the failure of an Eligible Holder to properly complete or file such joint election forms in the form and manner and within the time prescribed by the Tax Act (or any applicable provincial legislation). In its sole discretion, Mercator or any successor corporation may choose to sign and return a joint election form received by it more than 90 days following the Effective Date, but will have no obligation to do so.

Upon receipt of a letter of transmittal in which an Eligible Holder has indicated that the Eligible Holder intends to make a Section 85 Election, Mercator will promptly make available a tax instruction letter (and a tax instruction letter for the equivalent Quebec election, if applicable), together with the relevant tax election forms (including the Quebec tax election forms, if applicable) on Mercator’s website at ▇▇▇.▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇.▇▇▇ and on request made by checking the appropriate box in on the Letter of Transmittal Mercator will separately distribute such materials to the Eligible Holder.

Section 3.03 No Fractional Mercator Shares

No fractional Mercator Shares shall be issued to Former Creston Shareholders. The number of Mercator Shares to be issued to Former Creston Shareholders shall be rounded down to the nearest whole Mercator Share in the event that a Former Creston Shareholder is entitled to a fractional share representing less than a whole Mercator Share.

Section 3.04 Fractional Cash Consideration

Any Cash Consideration payable to a Former Creston Shareholder shall be rounded up to the next whole cent.

ARTICLE FOUR

are ultimately not entitled, for any reason, to be paid fair value for their Creston Shares shall be deemed to have participated in the Arrangement, as of the Effective Time, on the same basis as a non-dissenting holder of Creston Shares and shall be entitled to receive only the consideration contemplated in Section 3.01(b) hereof that such holder would have received pursuant to the Arrangement if such holder had not exercised Dissent Rights,

but in no case shall Mercator, Creston or any other person be required to recognize holders of Creston Shares who exercise Dissent Rights as holders of Creston Shares after the time that is immediately prior to the Effective Time, and the names of such holders of Creston Shares who exercise Dissent Rights shall be deleted from the central securities register as holders of Creston Shares at the Effective Time and Mercator shall be recorded as the registered holder of the Creston Shares so transferred and shall be deemed to be the legal and beneficial owner of such Creston Shares.

DELIVERY OF CONSIDERATION

Section 5.01 Delivery of Consideration

Upon surrender to the Depositary for cancellation of a certificate that immediately before the Effective Time represented one or more outstanding Creston Shares that were exchanged for the Consideration in accordance with Section 3.01 hereof, together with such other documents and instruments as would have been required to effect the transfer of the Creston Shares formerly represented by such certificate under the BCBCA and the articles of Creston and such additional documents and instruments as the Depositary may reasonably require, the holder of such surrendered certificate shall be entitled to receive in exchange therefor, and the Depositary shall deliver to such holder following the Effective Time, a certificate representing the Mercator Shares that such holder is entitled to receive in accordance with Section 3.01 hereof and a cheque for the Cash Consideration to which such holder is entitled.

After the Effective Time and until surrendered for cancellation as contemplated by Section 5.01(a) hereof, each certificate that immediately prior to the Effective Time represented one or more Creston Shares shall be deemed at all times to represent only the right to receive in exchange therefor a certificate representing Mercator Shares and the Cash Consideration that the holder of such certificate is entitled to receive in accordance with Section 3.01 hereof.

Section 5.02 Lost Certificates

In the event any certificate, that immediately prior to the Effective Time represented one or more outstanding Creston Shares that were exchanged for Mercator Shares and the cash consideration in accordance with Section 3.01 hereof, shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the holder claiming such certificate to be lost, stolen or destroyed, the Depositary shall deliver in exchange for such lost, stolen or destroyed certificate, a certificate representing Mercator Shares and a cheque in the amount of the cash consideration that such holder is entitled to receive in accordance with Section 3.01 hereof. When authorizing such delivery of a certificate representing Mercator Shares and the Cash Consideration that such holder is entitled to receive in exchange for such lost, stolen or destroyed certificate, the holder to whom a certificate representing such Mercator Shares and a cheque in the amount of the Cash Consideration is to be delivered shall, as a condition precedent to the delivery of such Mercator Shares and cheque, give a bond satisfactory to Mercator and the Depositary

in such amount as Mercator and the Depositary may direct, or otherwise indemnify Mercator and the Depositary in a manner satisfactory to Mercator and the Depositary, against any claim that may be made against Mercator or the Depositary with respect to the certificate alleged to have been lost, stolen or destroyed and shall otherwise take such actions as may be required by the articles of Creston.

Section 5.03 Distributions with Respect to Unsurrendered Certificates

No dividend or other distribution declared or made after the Effective Time with respect to Mercator Shares with a record date after the Effective Time shall be delivered to the holder of any unsurrendered certificate that, immediately prior to the Effective Time, represented outstanding Creston Shares unless and until the holder of such certificate shall have complied with the provisions of Section 5.01 or Section 5.02 hereof. Subject to applicable law and to Section 5.04 hereof, at the time of such compliance, there shall, in addition to the delivery of a certificate representing Mercator Shares and a cheque for the Cash Consideration to which such holder is thereby entitled, be delivered to such holder, without interest, the amount of the dividend or other distribution with a record date after the Effective Time theretofore paid with respect to such Mercator Shares.

Section 5.04 Withholding Rights

Mercator, Amalco and the Depositary shall be entitled to deduct and withhold from the consideration or other amounts payable to any Former Creston Shareholder such amounts as Mercator or the Depositary is required or permitted to deduct and withhold with respect to such payment under the Tax Act, the U.S. Tax Code or any provision of any applicable federal, provincial, state, local or foreign tax law or treaty, in each case, as amended. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to the Former Creston Shareholder in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority.

Section 5.05 Limitation and Proscription

To the extent that a Former Creston Shareholder shall not have complied with the provisions of Section 5.01 or Section 5.02 hereof on or before the date that is six years after the Effective Date (the "final proscription date"), then the Mercator Shares that such Former Creston Shareholder was entitled to receive shall be automatically cancelled without any repayment of capital in respect thereof and the certificates representing such Mercator Shares, together with the cash consideration to which such Former Creston Shareholder was entitled, shall be delivered to Mercator by the Depositary for cancellation, and the interest of the Former Creston Shareholder in such Mercator Shares and the Cash Consideration to which it was entitled shall be terminated as of such final proscription date. For great certainty, on such date, any certificate formerly representing Creston Shares shall cease to represent a claim or interest of any kind or nature against Mercator or Creston.
