8% CONVERTIBLE PROMISSORY NOTE

US $_______________

     February___, 2013

FOR VALUE RECEIVED, the undersigned, JMG EXPLORATION, INC., a Nevada corporation (the “Company”), hereby promises to pay to the order of __________________________________ (the “Holder”), the principal sum of ________________________ DOLLARS (US $________________), with interest on the outstanding principal amount at the rate of eight percent (8%) per annum, compounded annually, payable as set forth below.

This Convertible Promissory Note is one of a series of convertible promissory notes of like tenor and ranking without priority over one another (collectively, the “Notes”) made by the Company in favor of certain lenders (the “Lenders”) which have been or will issued by the Company pursuant to that certain 8% Promissory Notes, $7,000,000 Offering, Term Sheet Dated February 5, 2013, as such Term Sheet may be supplemented or amended from time to time (the “Term Sheet”). Any payments made by the Company with respect to this Note or any of the other Notes shall be made to each of the Lenders on a pro rata basis in accordance with the aggregate principal and interest owing under each of the Notes then outstanding.  To the extent any Lender receives any payment in excess of its pro rata share of such payment, such amount shall be held in trust and delivered over to the Company for the benefit of all of the Lenders then entitled to receive such amounts.  Capitalized terms used in this Note and not otherwise defined herein shall have the respective meanings set forth in the Term Sheet.

1.

Maturity Date.  The “Maturity Date” of this Note is February 15, 2015.   

2.

Interest Payment.  Interest shall accrue and be payable on the principal amount hereof at a rate per annum equal to eight percent (8%) (the “Interest Rate”), which interest shall be payable at such time or times as the principal of this Note is due and payable.  Accrued interest shall be compounded annually and added to the outstanding principal hereof.  Interest shall be calculated on the basis of a year of 365 days and for the number of days actually elapsed.  All payments hereunder shall be applied first to accrued interest and thereafter to principal.  The payments of principal and interest hereunder shall be made in coin or currency of the United States of America which at the time of payment shall be legal tender therein for the payment of public and private debts.  

3.

Prepayment.  The Company may, at its option, prepay any principal or interest due hereunder at any time upon thirty (30) days’ written notice to Holder.

4.

Conversion.  This Note shall be convertible into shares of common stock of the Company (the “Common Stock”) as set forth below:   

(a)

Conversion At Any Time Prior to Maturity Date At Option of Holder.  The outstanding principal and accrued interest of this Note may be converted at any time prior to the Maturity Date at the option of Holder, exercisable by written notice to the Company. Upon receipt by the Company of the written notice to exercise, together with this Note, the outstanding principal and accrued interest of this Note will automatically convert into that number of shares of Common Stock determined by dividing

(i) the amount of principal and interest then outstanding hereon (the “Note Amount”), by (ii) the Conversion Rate.  For purposes of this Note, the “Conversion Rate” means $1.50 per share prior to the proposed 1 for 2 reverse stock split of the Company’s Common Stock (the “Reverse Split”), and $3.00 per share after the Reverse Split.  In order for Holder to voluntarily convert this Note into shares of Common Stock, Holder shall surrender this Note (or, if Holder alleges that this Note has been lost, stolen or destroyed, a lost note affidavit and agreement reasonably acceptable to the Company to indemnify the Company against any claim that may be made against the Company on account of the alleged loss, theft or destruction of this Note), at the principal office of the Company, together with written notice that Holder elects to convert all the Note Amount.  Such notice shall state Holder’s name or the names of the nominees in which Holder wishes the certificate or certificates for shares of Common Stock to be issued. The close of business on the date of receipt by the Company of the Note (or lost note affidavit and agreement) and notice shall be the time of conversion (the “Conversion Time”), and the shares of Common Stock issuable upon conversion of the Note shall be deemed to be outstanding of record as of such date. The Company shall, as soon as practicable after the Conversion Time, issue and deliver to Holder or to his, her or its nominees, a certificate or certificates for the number of full shares of Common Stock issuable upon such conversion in accordance with the provisions hereof.  

(b)

Conversion At Any Time Prior to Maturity Date At Option of Company.  The outstanding principal and accrued interest of this Note may be converted at any time prior to the Maturity Date at the option of the Company, exercisable by written notice to the Holder. Upon delivery by the Company to the Holder of the written notice to exercise, the outstanding principal and accrued interest of this Note will automatically convert into that number of shares of Common Stock determined by dividing (i) the Note Amount, by (ii) the Conversion Rate.  Upon receipt of notice of conversion by the Company, the Holder shall surrender this Note (or, if Holder alleges that this Note has been lost, stolen or destroyed, a lost note affidavit and agreement reasonably acceptable to the Company to indemnify the Company against any claim that may be made against the Company on account of the alleged loss, theft or destruction of this Note), at the principal office of the Company.  Holder also shall provide the name or names in which Holder wishes the certificate or certificates for shares of Common Stock to be issued. The close of business on the date of notice shall be the time of conversion by the Company, and the shares of Common Stock issuable upon conversion of the Note shall be deemed to be outstanding of record as of such date. The Company shall, as soon as practicable after conversion of the Note, issue and deliver to Holder or to his, her or its nominees, a certificate or certificates for the number of full shares of Common Stock issuable upon such conversion in accordance with the provisions hereof.

(c)

Mandatory Conversion At Maturity Date.  If the principal amount and accrued interest on this Note are not prepaid in full by the Company prior to the Maturity Date, or if this Note is not voluntarily converted by Holder prior to the Maturity Date, then effective on and as of the Maturity Date the outstanding principal and accrued interest of this Note will automatically convert into that number of shares of Common Stock determined by dividing (i) the Note Amount by (ii) the Conversion Rate.  Holder shall be sent written notice of the mandatory conversion. Upon receipt of such notice, Holder shall surrender this Note (or, if Holder alleges that this Note has been lost, stolen or destroyed, a lost note affidavit and agreement reasonably acceptable to the Company to indemnify the Company against any claim that may be made against the Company on account of the alleged loss, theft or destruction of this Note), at the principal office of the Company. Holder also shall provide the name or names in which Holder wishes the certificate or certificates for shares of Common Stock to be issued. The close of business on the Maturity Date shall be the time of the mandatory conversion, and the shares of Common Stock issuable upon mandatory conversion of the Note shall be deemed to be outstanding of record as of such date. The Company shall, as soon as practicable after the receipt of the Note or lost note affidavit, issue and deliver to Holder or to his, her or its nominees, a certificate or certificates for the number of full shares of Common Stock issuable upon such mandatory conversion in accordance with the provisions hereof.

(d)

Upon the conversion of this Note pursuant to this Section 4, no fractional shares or scrip representing fractional shares shall be issued.  With respect to any fraction of a share called for upon the conversion of this Note or any portion hereof, a cash amount equal to such fraction shall be paid to the Holder.

(e)

Adjustment to Conversion Rate.  Prior to conversion of this Note by the Holder or the Company, the Conversion Rate will be subject to adjustment from time to time as provided in this Section 4(d).

(i)

Adjustment of Conversion Rate upon Issuance of Common Stock.  If and whenever on or after the original date of this Note, the Company issues or sells, or in accordance with this Section 4(d) is deemed to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account of the Company) for no consideration or a consideration per share (the “New Securities Issuance Price”) less than a price equal to the Conversion Rate in effect immediately prior to such time (the “Applicable Price”) (the foregoing, a “Dilutive Issuance”), then immediately after such issue or sale, the Conversion Rate then in effect shall be reduced to an amount equal to the New Securities Issuance Price.  For purposes of determining the New Securities Issuance Price under this Section 4(d)(i), the following shall be applicable:

(A)

Issuance of Options.  If the Company in any manner grants or sells any rights, warrants or options to subscribe for or purchase Common Stock (collectively “Options”) and the lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exchange or exercise of any stock or securities (other than Options) directly or indirectly convertible into or exchangeable or exercisable for Common Stock (collectively “Convertible Securities”) issuable upon exercise of such Option is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share.  For purposes of this Section 4(d)(i)(A), the “lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exchange or exercise of any Convertible Securities issuable upon exercise of such Option” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon granting or sale of the Option, upon exercise of the Option and upon conversion, exchange or exercise of any Convertible Security issuable upon exercise of such Option.  No further adjustment of the Conversion Rate shall be made upon the actual issuance of such Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such Common Stock upon conversion, exchange or exercise of such Convertible Securities.

(B)

Issuance of Convertible Securities.  If the Company in any manner issues or sells any Convertible Securities and the lowest price per share for which one share of Common Stock is issuable upon such conversion, exchange or exercise thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance of sale of such Convertible Securities for such price per share.  For the purposes of this Section 4(d)(i)(B), the “lowest price per share for which one share of Common Stock is issuable upon such conversion, exchange or exercise” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the issuance or sale of the Convertible

3

Security and upon the conversion, exchange or exercise of such Convertible Security.  No further adjustment of the Conversion Rate shall be made upon the actual issuance of such Common Stock upon conversion, exchange or exercise of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of the Conversion Rate had been or are to be made pursuant to other provisions of this Section 4(d)(i), no further adjustment of the Conversion Rate shall be made by reason of such issue or sale.

(C)

Change in Option Price or Rate of Conversion.  If the purchase or exercise price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exchange or exercise of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exchangeable or exercisable for Common Stock changes at any time, the Conversion Rate in effect at the time of such change shall be adjusted to the Conversion Rate which would have been in effect at such time had such Options or Convertible Securities provided for such changed purchase price, additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold.  For purposes of this Section 4(d)(i)(C), if the terms of any Option or Convertible Security that was outstanding as of the original date of this Note are changed in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such change.  No adjustment shall be made if such adjustment would result in an increase of the Conversion Rate then in effect.

(D)

Calculation of Consideration Received.  In case any Option is issued in connection with the issue or sale of other securities of the Company, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options will be deemed to have been issued for a consideration of $0.01.  If any Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount received by the Company therefor.  If any Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company will be the fair value of such consideration, except where such consideration consists of marketable securities, in which case the amount of consideration received by the Company will be the arithmetic average of the closing sale prices of such securities during the ten (10) consecutive trading days ending on the date of receipt of such securities.  The fair value of any consideration other than cash or securities will be determined jointly by the Company and the Lenders holding a majority or more of the outstanding principal balance of the Notes (the “Majority Lenders”).  If any Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such Common Stock, Options or Convertible Securities, as the case may be.  

(E)

Record Date.  If the Company takes a record of the  holders of Common Stock for the purpose of entitling them (I) to receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (II) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have

4

been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be.

(ii)

Adjustment of Conversion Rate upon Subdivision or Combination of Common Stock.  If the Company at any time subdivides (by any stock split, stock dividend, recapitalization or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Conversion Rate in effect immediately prior to such subdivision will be proportionately reduced.  If the Company at any time combines (by combination, reverse stock split or otherwise) its outstanding shares of Common Stock into a smaller number of shares and the Conversion Rate in effect immediately prior to such combination will be proportionately increased.

(iii)

Other Events.  If any event occurs of the type contemplated by the provisions of this Section 4(d) but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Company’s Board of Directors will make an appropriate adjustment in the Conversion Rate so as to protect the rights of the Lenders; provided that no such adjustment will increase the Conversion Rate as otherwise determined pursuant to this Section 4(d).

(iv)

Notices.

(A)

Immediately upon any adjustment of the Conversion Rate pursuant to this Section 4(d), the Company will give written notice thereof to the Holder, setting forth in reasonable detail, and certifying, the calculation of such adjustment.

(B)

The Company will give written notice to the Holder at least ten (10) business days prior to the date on which the Company closes its books or takes a record (I) with respect to any dividend or distribution upon the Common Stock, (II) with respect to any pro rata subscription offer to holders of Common Stock or (III) for determining rights to vote with respect to any merger, sale of a majority of the assets, dissolution or liquidation, provided that such information shall be made known to the public prior to or in conjunction with such notice being provided to such holder.

(C)

The Company will also give written notice to the Holder at least ten (10) business days prior to the date on which any merger, sale of a majority of the assets, dissolution or liquidation will take place, provided that such information shall be made known to the public prior to or in conjunction with such notice being provided to such holder.

5.

No Waiver.  No failure or delay by the Holder in exercising any right, power or privilege under this Note shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.  The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.  No course of dealing between the Company and the Holder shall operate as a waiver of any rights by the Holder.

6.

Waiver of Presentment and Notice of Dishonor.  The Company hereby waives presentment, notice of dishonor, protest and all other demands and notices in connection with the delivery, acceptance, performance or enforcement of this Note.
