Notes to the Unaudited Pro Forma Condensed Combined Financial Statements

Note 1. Basis of Presentation

The unaudited pro forma condensed combined balance sheet as of September 30, 2013 is based on the unaudited condensed consolidated balance sheets of Contango and Crimson as of September 30, 2013, adjusted to reflect the following items as though they had occurred on September 30, 2013:

• The purchase price allocation to assets to be acquired and liabilities to be assumed in the merger;

• The issuance of 0.08288 share of Contango common stock for each share of Crimson common stock, and the exchange of Crimson’s stock options to Contango’s stock options using the 0.08288 exchange rate;

• The assumption by Contango of approximately $235.4 million of Crimson’s long-term debt;

• The refinancing of Crimson’s First Lien Revolver Credit Agreement with a new revolving credit facility with an increased borrowing base;

• Repayment of Crimson’s Second Lien Loan from cash on hand and borrowings under the new revolving credit facility.

The unaudited pro forma condensed combined statements of operations for the three months ended September 30, 2013 and the year ended June 30, 2013 are based on the historical financial information of Contango and Crimson, recast to match the accounting periods to those of Contango as discussed below, and give effect to the merger as if it occurred on July 1, 2012.

The Crimson historical information included in the unaudited pro forma condensed combined statement of operations for the twelve months ended June 30, 2013 was derived by adding Crimson’s audited statement of operations for the twelve months ended December 31, 2012 to its unaudited condensed consolidated statement of operations for the six months ended June 30, 2013 and then subtracting its unaudited condensed consolidated statement of operations for the six months ended June 30, 2012.

The Crimson historical information included in the unaudited pro forma condensed combined statement of operations for the three months ended September 30, 2013 were derived from the unaudited consolidated statements of operations of Crimson Exploration, Inc. filed on the Contango Oil & Gas Form 8-K dated November 12, 2013.

Certain reclassifications have been made to Crimson’s historical financial statements presented herein to conform to Contango’s historical presentation.

In accordance with the Merger Agreement, Contango issued 0.08288 shares for each of the common shares of Crimson.

Additionally, as a result of the merger, all restricted shares of Crimson previously issued to its directors and employees were exchanged for shares of Contango’s Common Stock using the same conversion factor. Contango also issued new Contango stock options to replace outstanding Crimson stock options held by Crimson’s employees. The number of options granted and the strike price of the options was adjusted using the same conversion ratio as for the common stock.

Consideration paid by the Company consisted of approximately 3.9 million shares of Contango’s common stock issued in exchange for 46.6 million of Crimson’s shares outstanding as of September 30, 2013, including restricted stock vesting at the Transaction date and approximately 136 thousand of vested Contango stock options issued to Crimson’s employees in exchange for all Crimson stock options issued and outstanding as of September 30, 2013. All of Crimson’s restricted shares and stock options vested immediately prior to the merger.

The purchase price is calculated assuming fair value of the Company’s stock of $37.75 per share based upon the closing price of the Company’s common stock as of October 1, 2013.

Fair value of the Company’s options issued in exchange for Crimson’s stock options was calculated using the Black-Scholes Model and applying the following weighted-average assumptions: (a) risk-free interest rate of 0.62% to 1.35%; (b) expected life of 2.70 to 4.79 years; (c) expected volatility of 29.3% to 38.6%; and (d) expected dividend yield of 0%.  The weighted average fair value per share for the options was estimated to be $5.14.

(ii) To adjust the book value of Crimson’s oil and gas properties acquired to fair value, the commodity prices used in the determination of the fair value of natural gas and oil properties were based on future expected prices for oil, natural gas and NGLs, after adjustment for transportation fees and regional price differentials.

(iii) The fair value of the long-term debt to be assumed by the Company includes approximately $58.6 million and $176.8 million for the First and Second Lien debts, respectively. The fair value of the debt was calculated assuming 100% of Second Lien Loan principal outstanding of as of September 30, 2013 plus accrued interest of $59 thousand and $1.8 million for a 1% prepayment penalty included in such loan agreement. Crimson’s historical debt issuance cost of $768 thousand and unamortized balance of original issue discount of $4.1 million had been eliminated as a part of the pro forma fair value adjustments.

(iv) To accrue for transaction costs of approximately $2.8 million in advisory fees payable to Crimson’s financial advisor assumed by Contango at the acquisition date and to recognize additional current assets and liabilities, for a total of $1.2 million, related to the prior period adjustments to receivables and payable accounts, which were not reflected in Crimson’s historical financial statements as of September 30, 2013.

8

(v) Fair value of the deferred tax liabilities was calculated giving the tax effect of step-up adjustment for oil and gas properties. Contango received carryover tax basis in Crimson’s assets and liabilities because the merger is not a taxable transaction under the United States Internal Revenue Code. Based upon the purchase price allocation, a step-up in financial reporting carrying value related to the property to be acquired from Crimson resulted in an additional deferred tax liability of approximately $42.8 million assuming a 37% expected effective tax rate of the combined company.
Additionally, fair value of the deferred tax assets was increased by approximately $10.2 million due to elimination of a valuation allowance included in the historical financial statements of Crimson. This adjustment is based on the expectation that it is more likely than not that the majority of $110 million of Crimson’s accumulated Net Operating Losses (NOL’s) will be realized by the combined company in the foreseeable future.

(b) Financing and other Adjustments

(vi) Immediately subsequent to the closing of the merger, the Company assumed and immediately repaid Crimson’s $175.0 million debt with Barclays Bank PLC ("Barclays"), its $58.6 million debt with Wells Fargo, and $1.8 million in accrued interest and prepayment premiums. In order to finance the assumed debt, the Company entered into a $500 million four-year revolving credit facility with Royal Bank of Canada and other lenders (the “RBC Credit Facility”) with an initial hydrocarbon supported borrowing base of $275 million. The RBC Credit Facility replaced the Company's $40 million Amegy Credit Agreement. The Company incurred $2.2 million of arrangement and upfront fees in connection with the RBC Credit Facility. Borrowings under the RBC Credit Facility bear interest at a rate that is dependent upon LIBOR or the U.S. prime rate of interest, plus a margin dependent upon the amount outstanding. On October 1, 2013, the $235.4 million of assumed debt, accrued interest, and prepayment premium and $2.2 million of arrangement and upfront fees under the RBC Credit Facility were paid with the Company's existing cash of $127.6 million and drawings under our RBC Credit Facility of $110.0 million. For the period from October 1, 2013 through November 30, 2013, the effective interest rate on the facility was 4.25%.

(vii) Additionally, the following adjustments were recorded to reflect the assets and liabilities of the combined company as of the Transaction date:

• To accrue for transaction costs of approximately $1.7 million, including $1.65 million in advisory fees to be paid to the Company’s financial advisor and approximately $49 thousand in other estimated legal and advisory fees that will be payable related to the transaction, and which were not reflected in the Company’s historical financial statements.

• To accrue for a one-time cash bonus of approximately $4 million that will be paid to the former Chairman and CEO of the Company six months after the consummation of the merger.

Unaudited Pro Forma Condensed Combined Statement of Operations for the Year Ended June 30, 2013

(viii) The Crimson historical information included in the unaudited pro forma condensed combined statement of operations for the year ended June 30, 2013 is derived by adding Crimson’s audited statement of operations for the twelve months ended December 31, 2012 to its unaudited condensed consolidated statement of operations for the six months ended June 30, 2013 and then subtracting its unaudited condensed consolidated statement of operations for the six months ended June 30, 2012.

(ix) The Crimson pro forma depletion, depreciation and amortization (DD&A) expense for the year ended June 30, 2013 was calculated based on the value of proved oil and gas properties acquired from Crimson giving effect to the fair value adjustment to value of proved properties as a result of the acquisition accounting and estimated DD&A rate for the twelve months ended June 30, 2013. This depletion rate was calculated by dividing production for the twelve months ended June 30, 2013 by the total beginning of the period proved reserves calculated by adding back the production for the fifteen month period to the ending proved reserves as of

9

September 30, 2013. The reduction in depletion is offset by $543 thousand of amortization of the debt issuance costs related to the debt refinancing which took take place at the merger date.

(x) To adjust interest expense for:

• The repayment of the $175 million principal balance of the Second Lien Loan using cash available at the merger date and total borrowings of $110.0 million under the new RBC Credit Facility, as if such repayment had occurred on July 1, 2012, which reduced the interest expenses by approximately $20.9 million.

• Eliminating $1.3 million of expense related to amortization of the original issue discount on the Second Lien Loan. This amortization expense of debt origination discount was historically calculated using the effective interest method over the remaining life of the debt instrument and was included in the historical interest expense of Crimson for the year ended June 30, 2013.

(xi) To adjust the income tax provision for the estimated effects of combining Contango’s and Crimson operations and other pre-tax pro forma adjustments using a combined federal and state tax rate of 37%.

(xii) To adjust earnings per share and weighted average common stock outstanding to reflect the issuance of approximately 3.9 million shares of Contango common stock for the merger, as if these shares had been issued and outstanding since July 1, 2012. The pro forma diluted weighted average shares outstanding for the year ended June 30, 2013 does not include 136 thousand option shares assumed issued in conjunction with the merger because they are antidilutive.

10

Unaudited Pro Forma Condensed Combined Statement of Operations for the Three Months Ended September 30, 2013

(viii) The Crimson historical information included in the unaudited pro forma condensed combined statement of operations for the three months ended September 30, 2013 reflect the actual results reported for Crimson Exploration on Contango Form 8-K dated November 12, 2013.

(ix) The Crimson pro forma DD&A expense for the three months ended September 30, 2013 was calculated based on the value of proved oil and gas properties acquired from Crimson, giving effect to the fair value adjustment to value of proved properties as a result of the acquisition accounting and the estimated DD&A rate for the three months ended September 30, 2013. This depletion rate was calculated by dividing production for the three months ended September 30, 2013 by the total beginning of the period proved reserves calculated by adding back the production for the three months period to the ending proved reserves as of September 30, 2013. The reduction in depletion is offset by $136 thousand in debt issuance costs related to the debt refinancing which took place at the merger date.

(x) To adjust interest expense for:

• The assumed repayment of the $175 million principal balance of the Second Lien Loan using cash available at the Transaction date and total borrowings of $110.0 million under the new RBC Credit Facility, as if such repayment had occurred on July 1, 2012, which reduced the interest expenses by approximately $5.2 million.

• Eliminating $0.4 million of the amortization expense related to debt origination discount of on the Second Lien Loan. This amortization expense of debt origination discount was historically calculated using the effective interest method over the remaining life of the debt instrument and was included in the historical interest expense of Crimson for the three months ended September 30, 2013.

(xi) To adjust the income tax provision for the estimated effects of combining Contango’s and Crimson operations and other pre-tax pro forma adjustments using a combined federal and state tax rate of 37%.

(xii) To adjust earnings per share and weighted average common stock outstanding to reflect the issuance of approximately 3.9 million of Contango common stock for the Crimson acquisition, as if these shares had been issued and outstanding since July 1, 2012. The pro forma diluted weighted average shares outstanding for the three months ended September 30, 2013 includes 136 thousand options assumed issued in conjunction with the merger.

Summary Pro Forma Combined Oil and Natural Gas Reserve and Production Data

The following table presents selected unaudited pro forma information regarding the Company’s proved reserves as of September 30, 2013, giving effect to the acquisition of Crimson proved reserves as if they were acquired on September 30, 2013. Contango’s reserve disclosures are based on a reserve report prepared by the Company’s independent reserve engineer as of September 30, 2013, in accordance with the guidelines established by the Securities and Exchange Commission (the “SEC”). Crimson’s reserve information as of September 30, 2013 is based on the internal reserve report as of September 30, 2013 and was not reviewed by any independent reserve engineer.

There are numerous uncertainties inherent in estimating quantities and values of proved reserves and in projecting future rates of production and the amount and timing of development expenditures, including many factors beyond the property owner’s control. The following reserve data represents estimates only and should not be construed as being precise. The assumptions used in preparing these estimates may not be realized, causing the quantities of oil and gas that are ultimately recovered, the timing of the recovery of oil and gas reserves, the production and operating costs incurred and the amount and timing of future development expenditures to vary from the estimates presented herein. Actual production, revenues and expenditures with respect to reserves will vary from estimates and the variances may be material.

These estimates were calculated using the twelve-month average of the first-day-of-the-month reference prices as adjusted for location and quality differentials. Any significant price changes will have a material effect on the quantity

and present value of the reserves shown below. These estimates depend on a number of variable factors and assumptions, including historical production from the area compared with production from other comparable producing areas, the assumed effects of regulations by governmental agencies, assumptions concerning future oil and gas prices, and assumptions concerning future operating costs, transportation costs, severance and excise taxes, development costs and workover and remedial costs.
