EXPLANATORY NOTE

This Amendment No. 1 on Form 8-K/A amends the Current Report on Form 8-K of ION Geophysical Corporation (“ION”) that was filed with the Securities and Exchange Commission (“SEC”) on September 23, 2008.

SIGNATURES

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial statements and related information have been compiled by the application of pro forma adjustments to the historical consolidated financial statements of ION and to reflect the combination of ION’s historical consolidated financial data and the combined historical financial data of ARAM Systems Ltd., Canadian Seismic Rentals Inc. and their affiliated companies, which we sometimes refer to as the “ARAM Group of Companies” or “ARAM.” The unaudited pro forma condensed combined balance sheet of ION as of June 30, 2008 gives effect to ION’s acquisition of the shares of ARAM Systems Ltd. and Canadian Seismic Rentals Inc., and the related financing transactions in connection therewith, as if such events had occurred as of such date. The unaudited pro forma condensed combined statements of operations of ION for the year ended December 31, 2007 and for the six months ended June 30, 2008, give effect to such transactions as if such events had occurred as of January 1, 2007.

The unaudited pro forma adjustments are based upon currently available information and assumptions that we believe to be reasonable under the circumstances. The following unaudited pro forma condensed combined financial data are for informational purposes only and do not purport to represent what our results of operations or financial position actually would have been if the transactions referred to above had occurred at any date, and should not be taken as representative of our future results of operations or financial position. The unaudited pro forma condensed combined financial statements and related information do not include any adjustments related to any restructuring charges, profit improvements, potential cost savings or one-time charges which may result from ION’s acquisition of ARAM, and the related financing transactions, or the result of final valuations of certain tangible and intangible assets and liabilities.

The following unaudited pro forma condensed combined financial statements and related information should be read in conjunction with:

	•		ION’s historical audited consolidated financial statements as of and for the year ended December 31, 2007 and unaudited consolidated financial statements as of June 30, 2008 and for the six months ended June 30, 2007 and 2008, as included in ION’s Annual Report on Form 10-K for the fiscal year ended December 31, 2007, as amended by Form 10-K/A filed with the SEC on March 4, 2008, and in ION’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2008; and

	•		The audited combined balance sheets of the ARAM Group of Companies as of December 31, 2007 and 2006, the related audited combined statements of net income, comprehensive income and retained earnings and cash flows for the years ended December 31, 2007, 2006 and 2005, the unaudited combined balance sheet of the ARAM Group of Companies as of June 30, 2008 and the related unaudited combined statements of net income, comprehensive income and retained earnings and cash flows for the six months ended June 30, 2008 and 2007, filed as Exhibit 99.2 to this Amendment No. 1 on Form 8-K/A, and incorporated herein by reference.

The acquisition of ARAM has been accounted for using purchase accounting in accordance with Statement of Financial Accounting Standards, or SFAS, No. 141 “Business Combinations.” The unaudited pro forma condensed combined financial data presented, including the allocation of the purchase price, is based on preliminary estimates of the fair market values of assets acquired and liabilities assumed, available information and assumptions and will be revised as additional information becomes available. As of the date of this Amendment No. 1 on Form 8-K/A, ION has not completed the valuation studies necessary to estimate the final fair market values of the assets it has acquired and liabilities it has assumed and the related allocation of purchase price. The actual adjustments to ION’s consolidated financial statements will depend on a number of factors, many of which are not presently known. Therefore, actual adjustments will differ from the pro forma adjustments, and the differences may be material.

ION GEOPHYSICAL CORPORATION
NOTES TO UNAUDITED PRO FORMA FINANCIAL INFORMATION

(1) Certain amounts reflected in the historical financial statements of the ARAM Group of Companies have been reclassified to conform to ION’s historical financial statement presentation. Also, the balances have been translated from their Canadian dollar functional currency to the U.S. dollar at an exchange rate. A reconciliation has been provided after these notes to adjust for these reclassifications and to translate the historical Canadian financial statements to the U.S. dollar.

(2) The following is the preliminary estimate of the purchase price (in thousands) for the ARAM acquisition:


Cash payment paid for ARAM shares	$	235,969
Short-term notes issued to one of the sellers		45,000
ION common stock valued at $13.49 per share		48,958
Estimated acquisition costs		6,000

Total purchase price	$	335,927

The purchase price is subject to certain working capital adjustments after closing. In addition, ION issued promissory notes in the aggregate original principal amount of $45.0 million as part of the purchase price. When ION repays these notes, $35.0 million of the cash repayment amount will be deposited into escrow for post-closing purchase price adjustments and to secure indemnification obligations of the parties.

The purchase price reflects adjustments related to the estimated unpaid (at closing) seller transaction costs and change of control payments of approximately $3.3 million (a reduction to the total cash payment for the ARAM shares); and an increase to the total cash payment for the ARAM shares related to the certain estimated pre-acquisition income tax receivables of approximately $10.7 million, for which claims for tax refunds will be filed with the appropriate taxing authorities and are anticipated to be received by ARAM subsequent to the closing date of the acquisition. This income tax receivable relates to $35 million (CAD) in total discretionary bonuses that ARAM paid to certain of its employees prior to the acquisition by ION. The payment of these bonuses was not a condition of continued employment subsequent to the acquisition.

This preliminary estimate of the purchase price has been allocated as presented below based upon a preliminary fair value assessment of the assets and liabilities of ARAM at June 30, 2008. This fair value assessment is expected to be finalized in the fourth quarter of 2008.

(3) To reflect pro forma adjustment to amortization expense ($14.7 million and $7.3 million for the year ended December 31, 2007 and the six months ended June 30, 2008, respectively) related to the acquired intangible assets (core technology, customer relationships, trade name and non-compete agreements). The acquired intangible assets will be amortized over their estimated useful lives ranging from 5 years to 10 years.

(4) To reflect the borrowings associated with the $125 million term loans, the revolving credit borrowings under ION’s Amended and Restated Credit Facility, borrowings under the Short-Term Bridge Loan, and the Senior Seller Note and the Subordinated Seller Note (as those terms are defined in the Form 8-K filed on September 23, 2008), which were made or entered into on September 18, 2008. The interest rate on the term loans and the revolving credit borrowings was 6.3% at September 30, 2008.

The $125 million term loans are subject to scheduled quarterly principal payments, commencing on December 31, 2008, until their maturity in September 2013. ION incurred approximately $3.5 million of costs associated with issuance of the term loans that will be amortized to maturity.

The Short-Term Bridge Loan of $40.0 million was borrowed under an unsecured senior increasing rate note in the original principal amount of $40.8 million. The Short-Term Bridge Loan was issued at a 2.0% original issue discount. The original principal amount of $40.8 million must be repaid in full on its maturity date of December 31, 2008. ION incurred approximately $1.9 million of costs associated with issuance of this loan that will be amortized to maturity. The interest rate on the Short-Term Bridge Loan was 13.6%, which is the weighted average of the set rates over the fourth quarter.

The maturity date of the Senior Seller Note in the original principal amount of $35.0 million is the earlier to occur of (x) September 18, 2009, and (y) the date that a cash amount equal to $35.0 million, plus an amount of interest accrued on the Senior Seller Note that is equal to 3.0% per annum (representing a portion of the total accrued and unpaid interest on the Senior Seller Note), is deposited into an escrow account. The Subordinated Seller Note’s original principal amount of $10.0 million and accrued interest thereon are due and payable on the date that is one day following the maturity date of the Senior Seller Note. For the Senior Seller Note, the interest rate was 9% per annum as of September 30, 2008, while the Subordinated Seller Note was at 10% per annum. Each of these notes interest rates increase over their respective terms. For the Senior Seller Note, the interest rate increases from 9% to 15% per annum, and the Subordinated Seller Note increases from 10% to 16% per annum.

Under the Amended and Restated Credit Facility, the Company is obligated by no later than December 31, 2008 to have sufficient cash on hand to repay (i) the $72.0 million borrowed under the revolving credit facility to pay a portion of the cash purchase price consideration for the ARAM acquisition and (ii) $45.0 million of aggregate unsecured indebtedness owed by the Company to one of the former shareholders of ARAM as part of the purchase price for the ARAM acquisition. It is anticipated that the Company will seek and obtain additional long-term debt financing to fund these repayment obligations on or before December 31, 2008.

ION currently expects to repay the indebtedness under the Short-Term Bridge Loan, the Senior Seller Note and the Subordinated Seller Note and pay down the $72.0 million revolving credit indebtedness under its Amended and Restated Credit Facility through proceeds from the additional debt financing. ION has entered into a commitment letter dated September 18, 2008 (the “Commitment Letter”), with Jefferies Finance LLC pursuant to which Jefferies Finance LLC has agreed, subject to the terms and upon satisfaction of the conditions contained in the Commitment Letter, to act in the capacities of sole advisor, sole administrative agent, sole collateral agent (if applicable), sole book-runner, sole lead arranger and sole syndication agent in connection with a proposed $150.0 million senior bridge loan facility. This bridge loan facility would be drawn down in the event that other types of additional debt financing, including other long-term indebtedness that ION may attempt to raise (such as high-yield note indebtedness), is not obtained. The Commitment Letter expires by its terms on December 31, 2008. Any funding under the bridge loan facility is subject to certain conditions that must be satisfied prior thereto, and no assurances can be made that ION will be successful in incurring this long-term indebtedness or any other indebtedness to refinance the Short-Term Bridge Loan, the Senior Seller Note, the Subordinated Seller Note and the $72.0 million revolving credit indebtedness under the Amended Credit Facility.

(5) To reflect the pro forma adjustment to interest expense associated with the $125 million term loans and the revolving credit borrowings under the Amended and Restated Credit Facility, the Short-Term Bridge Loan, the Senior Seller Note and the Subordinated Seller Note and the amortization impact associated with their debt costs. The interest rate on the term loans and the revolving credit borrowings under the Amended and Restated Credit

F-6

Facility as of September 30, 2008 was 6.3%. Because the interest rate is dependent on market conditions, a 1/8% change in interest rate would increase or decrease interest expense by $1.6 million for each outstanding loan.

(6) To eliminate the revenue ($3.6 million for the year ended December 31, 2007 and $1.2 million for the six months ended June 30, 2008) and costs of goods sold ($2.6 million for the year ended December 31, 2007 and $0.6 million for the six months ended June 30, 2008) associated with sales between ION and ARAM and to eliminate the balance sheet accounts associated with those activities.

(7) To reflect payments made by ARAM on the amounts due to its related parties and its former officers ($6.1 million at June 30, 2008) and its outstanding bank debt ($4.0 million at June 30, 2008). These balances were paid off by ARAM prior to the closing of the acquisition.

(8) To reflect the pro forma interest savings related to the payments made by ARAM on amounts due to its related parties and its outstanding bank debt (see Note 7). This pro forma interest savings adjustment assumes these interest-bearing obligations were paid off at the beginning of the period.

(9) To reflect the pro forma adjustments to stockholders’ equity (in thousands) as follows:


Issuance of ION common stock to fund a portion of the purchase price (3,629,211 shares valued at $13.49 per share)	$	48,958
Elimination of ARAM’s historical stockholders’ equity		(91,164	)
Entry to reflect the unrecognized profit on sales from ION to ARAM		(640	)

	$	(42,846	)

(10) To reflect the income tax benefit related to the effect of the pro forma adjustments at the applicable statutory rates.

(11) To reflect the pro forma adjustment to the weighted average number of shares outstanding resulting from the issuance of 3,629,211 shares of ION common stock.

(12) To reflect the pro forma adjustment to reduce ION’s accounts payable by $0.5 million and accrued liabilities by $0.7 million relating to the transaction costs accrued for at June 30, 2008. Because the total estimated transaction costs ($6.0 million) have been reflected as a reduction in cash, the amounts accrued for at June 30, 2008 were eliminated.

(13) To reflect a pro forma adjustment of $2.4 million to remove the cash surrender value of certain ARAM life insurance policies that were excluded from the acquisition of ARAM by ION.

(14) To reflect a pro forma adjustment ($3.7 million for the year ended December 31, 2007 and $3.1 million for the six months ended June 30, 2008) to conform ARAM’s rental pool depreciation accounting method with ION’s accounting policies. ARAM’s significant accounting policies are consistent with those of ION, with one exception: ARAM depreciates its rental equipment based upon a straight-line basis of 40% per annum (2.5 years), while ION depreciates these assets using a straight-line basis, using two to five years. Based upon ION’s initial assessment of the nature of the equipment in ARAM’s rental pool, the majority of these assets fall into the five-year category under ION’s accounting policy.
