CREDIT AGREEMENT

THIS CREDIT AGREEMENT (this “Agreement”) is made and entered into as of the Effective Date, among GASCO ENERGY, INC., a Nevada corporation (“Borrower”), the Lenders from time to time party to this Agreement (each a “Lender” and collectively, the “Lenders”) and OROGEN ENERGY, INC., a Delaware corporation, as administrative agent for itself and the other Lenders (in such capacity, and together with its successors in such capacity, the “Agent”).

RECITALS

A. Borrower has requested that Lenders extend credit to Borrower in the maximum principal amount of $5,000,000 in the form of a revolving credit facility.

B. Lenders are willing to extend the requested credit on the terms and conditions of this Agreement.

Accordingly, for and in consideration of the premises, the mutual covenants and agreements set out in this Agreement, Borrower, Agent, and Lenders agree as follows:

ARTICLE I

GENERAL TERMS

Section 1.01 Definitions. Defined terms used in this Agreement are set out on Appendix 1.

Section 1.02 Accounting Principles. Accounting principles are applied under this Agreement in accordance with GAAP on a “consistent basis” when the accounting principles applied in a current period are comparable in all material respects to those accounting principles applied in a preceding period.

Section 1.03 References to Documents. Unless otherwise expressly provided in this Agreement, (a) references to corporate formation or governance documents, contractual agreements (including this Agreement and the Loan Documents) and other contractual instruments shall be deemed to include all subsequent amendments, restatements, extensions, supplements, substitutions, and other modifications thereto, but only to the extent that such amendments, restatements, extensions, supplements and other modifications are not prohibited by any Loan Document, and (b) references to any Law shall include all statutory and regulatory provisions consolidating, amending, replacing, supplementing or interpreting such Law.

Section 1.04 Time. Unless otherwise indicated, all time references (e.g., 11:00 a.m.) are to Central time (daylight or standard, as applicable). This Agreement shall be deemed to have closed at 9:30 a.m. on the Closing Date.

ARTICLE II

LOAN COMMITMENT AND TERMS

Section 2.01 The Revolving Credit Facility. Subject to the terms and conditions of, and relying on the representations and warranties contained in, this Agreement, each Lender jointly and severally agrees to loan to Borrower an amount up to and not to exceed its Revolving Commitment Percentage of the Revolving Committed Amount in one or more loans which Borrower may borrow,

repay, and reborrow under this Agreement (collectively, the “Revolving Credit Facility”). Each Lender’s Commitment to lend under the Revolving Credit Facility shall expire at noon on the last Business Day preceding the Revolving Credit Termination Date; provided that, Borrower’s obligations and each Lender’s rights under the this Agreement and the other Loan Documents shall continue in effect until each Lenders’ Commitment has terminated and the Obligation is paid in full.

Section 2.02 Advance Procedure.

(a) Borrower may request an Advance under the Revolving Credit Facility by submitting an Advance Request to Agent. An Advance Request is irrevocable and binding on Borrower. Each Advance Request must be received no later than 11:00 a.m. on the Business Day immediately preceding the date of the proposed Advance. Advances under this Agreement may be made by Agent pursuant an oral request of Borrower but Borrower covenants and agrees to furnish to Agent written confirmation of any such oral request within 2 days after the date of the Advance, but any such Advance shall be deemed to be made under and entitled to the benefits of this Agreement irrespective of any failure by Borrower to furnish such written confirmation.

(b) Agent shall make each Advance available to Borrower by funding such Advance to Borrower’s Operating Account, and all amounts made available to Borrower by Agent (whether in Borrower’s Operating Account or otherwise) shall be deemed to be Advances made pursuant to this Agreement.

(c) Each Advance under the Revolving Credit Facility (i) must occur on a Business Day and no later than the Business Day immediately preceding the Revolving Credit Termination Date, (ii) may not exceed an amount equal to the excess of the Revolving Committed Amount over the Revolving Principal Amount, and (iii) after giving effect to any Advance, the Revolving Principal Amount may not exceed the Revolving Committed Amount.

(d) Upon its receipt of an Advance Request from Borrower, Agent shall promptly notify each Lender of the Advance Request and its contents. By 12:00 noon on the date of the proposed Advance, each Lender shall either remit its Revolving Commitment Percentage of each requested Advance by wire transfer to Agent pursuant to Agent’s wire transfer instructions (or as otherwise directed by Agent) in funds that are available for immediate use by Agent or confirm in writing that it has wired such amount directly to the Borrower’s Operating Account. Subject to receipt of such funds, Agent shall make such funds available to Borrower in the Borrower’s Operating Account. Absent contrary written notice from a Lender, Agent may assume that each Lender has made its Revolving Commitment Percentage of the requested Advance available to Agent or to Borrower on the date of the proposed Advance. If a Lender has confirmed that it will remit funds to Agent, then Agent may, in reliance upon such assumption (but is not required to), make available to Borrower a corresponding amount.

(e) If Agent funds the corresponding amount on behalf of a Lender and that Lender fails to make its Revolving Commitment Percentage of any requested Advance available to Agent on the date of the proposed Advance, Agent may recover the applicable amount on demand from that Lender, together with interest at the Default Rate for the period commencing on the date the amount was made available to Borrower by Agent and ending on (but excluding) the date Agent recovers the amount from that Lender. While the Agency Agreement is in place, Agent and Lenders agree that the funding mechanics in the Agency Agreement shall govern and control, notwithstanding anything to the contrary set forth in this Agreement.

(f) If either Lender fails to fund its Revolving Commitment Percentage of any Advance (either to Agent or to the Borrower) (each such Lender a “Defaulting Lender”), the other Lender shall fund the amount of the Advance and shall be entitled to contribution from the Defaulting Lender in an amount equal to the aggregate principal amount which a Defaulting Lender fails to fund and which such other Lender funds, plus interest from the date the applicable Advance is made available to the Borrower at the Default Rate.

Section 2.03 Payments and Interest Rates. The Revolving Principal Amount shall accrue interest at the following rates and principal and interest shall be due and payable, subject to Section 6.02, as follows:

(a) The Revolving Principal Amount shall accrue interest at a fixed annual rate of 8%.

(b) Upon the occurrence of a Default or an Event of Default (regardless of whether the Obligation has been accelerated), principal, past due interest, fees, and expenses (in each case, to the extent permitted by Law) in respect of the Obligation shall accrue interest at a fixed annual rate equal to 16%, provided that such annual rate may not exceed the Maximum Rate. Interest calculations are subject to certain recapture provisions set out herein.

(c) The Revolving Principal Amount, together with all accrued and unpaid interest, is due and payable on the Revolving Credit Termination Date.

Section 2.04 Computation. Interest on the Revolving Principal Amount and on the amount of all fees and other amounts due under the Loan Documents will be calculated on the basis of actual number of days elapsed (including the first day but excluding the last day), but computed as if each calendar year consisted of 360 days (unless computation would result in an interest rate in excess of the Maximum Rate, in which event the computation is made on the basis of a year of 365 or 366 days, as the case may be). All interest rate determinations and calculations by Lender, as applicable, are conclusive and binding, absent manifest error.

Section 2.05 Prepayment. If the Revolving Principal Amount at any time exceeds the Revolving Committed Amount, then Borrower shall immediately repay the Revolving Principal Amount, in at least the amount of that excess, together with all accrued and unpaid interest on the principal amount so repaid.

Section 2.06 Application of Payments. All payments, prepayments, and proceeds of Collateral shall be applied in the following order: (a) to all fees, expenses, late charges, collection costs, and other charges, costs and expenses for which Agent has not been paid or reimbursed under the Loan Documents, (b) accrued and unpaid interest on the Revolving Principal Amount, (c) to the remaining Revolving Principal Amount in the order Agent elects, and (d) to the remaining Obligation in the order and manner Agent elects.

Section 2.07 Fees.

(a) As consideration for Lenders’ Commitments under this Agreement, Borrower has issued to Lenders 250,000 shares of common stock by the Borrower and such issuance is irrevocable.

(b) To the extent permitted by Law, any fees due under this Agreement or any Loan Document (i) do not constitute compensation for the use, detention, or forbearance of money, (ii)

are in addition to, and not in lieu of, interest and expenses otherwise described in this Agreement or in any other Loan Document, (iii) are payable without offset, counterclaim or deduction, and in funds that will be available for immediate use by 12:00 noon on the date due, (iv) are non-refundable, (v) accrue interest, if not paid when due, at the Maximum Rate, and (vi) are calculated on the basis of actual number of days elapsed (including the first day but excluding the last day), but computed as if each calendar year consisted of 360 days (unless computation would result in an interest rate in excess of the Maximum Rate, in which event the computation is made on the basis of a year of 365 or 366 days, as the case may be). The fees described in this Article II are in all events subject to the provisions of Section 8.06.

Section 2.08 Waivers. Borrower and each surety, guarantor, endorser, and other party ever liable for payment of any sums of money payable pursuant to this Agreement jointly and severally waive notice, presentment, demand for payment, protest, notice of protest and non-payment or dishonor, notice of acceleration, notice of intent to accelerate, notice of intent to demand, diligence in collecting, grace, and all other formalities of any kind, and consent to all extensions without notice for any period or periods of time and partial payments, before or after maturity, and any impairment of any collateral securing this Agreement, all without prejudice to Agent or Lenders.
