UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

The following tables set forth certain unaudited pro forma condensed consolidated financial information giving effect to Techne Corporation’s (“Techne”) acquisition of Tocris Holdings Limited (“Tocris”).

The unaudited pro forma condensed consolidated statements of income for the year ended June 30, 2010 and for the six months ended December 31, 2010 (the “Pro Forma Income Statements”), give effect to Techne’s acquisition of Tocris, as discussed in Note 3, as if such acquisition had occurred on July 1, 2009, combining the results of Techne and Tocris for the year ended June 30, 2010 (Techne’s fiscal year end) and for the six month period ended December 31, 2010. The unaudited pro forma condensed consolidated balance sheet as of December 31, 2010 (the “Pro Forma Balance Sheet”) gives effect to the Tocris acquisition as if it had occurred on December 31, 2010, combining Techne’s December 31, 2010 balance sheet with Tocris’ December 31, 2010 balance sheet. The Pro Forma Income Statements and the Pro Forma Balance Sheet are hereafter collectively referred to as the “Pro Forma Financial Information”. The Pro Forma Financial Information is unaudited and does not purport to represent what Techne’s consolidated results of operations would have been if the Tocris acquisition had occurred on July 1, 2009, or what those results will be for any future periods, or what Techne’s consolidated balance sheet would have been if the Tocris acquisition had occurred on December 31, 2010.

The Pro Forma Financial Information is based upon the historical consolidated financial statements of Techne and Tocris and certain adjustments which Techne believes are reasonable, to give effect of the Tocris acquisition. The pro forma adjustments and Pro Forma Financial Information included herein were prepared using the acquisition method of accounting for the business combination. The pro forma adjustments are based on preliminary estimates and certain assumptions that Techne believes are reasonable under the circumstances. The purchase price allocation is considered preliminary and subject to change once Techne receives certain information it believes is necessary to finalize the acquisition accounting, as noted in Note 3 to the Pro Forma Financial Information.

The Pro Forma Financial Information has been compiled from the following sources with the following unaudited adjustments:

1. BASIS OF PRESENTATION

The accompanying Pro Forma Income Statements for the year ended June 30, 2010, and for the six month period ended December 31, 2010, give effect to Techne’s acquisition of Tocris as discussed in Note 3, as if such acquisition had occurred on July 1, 2009, combining the results of Techne and Tocris for the year ended June 30, 2010 and for the six month period ended December 31, 2010 (Tocris’ fiscal year end). The accompanying Pro Forma Balance Sheet as of December 31, 2010 gives effect to the Tocris acquisition as if it had occurred on December 31, 2010, combining the consolidated balance sheet of Techne and Tocris as of December 31, 2010. The Pro Forma Financial Information is unaudited and does not purport to represent what Techne’s consolidated results of operations would have been if the Tocris acquisition had occurred on July 1, 2009, or what those results will be for any future periods; or what Techne’s consolidated balance sheet would have been if the Tocris acquisition had occurred on December 31, 2010.

(a) Year Ended June 30, 2010

Tocris’ financial statements for the year ended June 30, 2010 were derived by removing the financial results for the six month period ended December 31, 2010 from its year ended December 31, 2010 financial results and adding the financial results for the six month period ended December 31, 2009.

(b) Six Month Period Ended December 31, 2010

The financial statements of Tocris for the six month period ended December 31, 2010 were derived by removing the financial results for the six month period ended June 30, 2010 from the December 31, 2010 financial results. No duplicated operating information is included in the periods presented.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Pro Forma Financial Information has been compiled in a manner consistent with the accounting policies adopted by Techne. The accounting policies of Tocris were not deemed to be materially different from those adopted by Techne. Adjustments were made for presentational differences between UK Generally Accepted Accounting Practice and U.S. Generally Accepted Accounting Principals (GAAP), as set out further in Note 4, together with adjustments arising as part of the acquisition accounting.

The Tocris financial information has been translated from pounds sterling to U.S. dollars using the average exchange rates applicable during the periods presented in the Pro Forma Statements of Income and the period end spot rate for the Pro Forma Balance Sheet.

3. TOCRIS ACQUISITION

On May 3, 2011, Techne announced that on April 28, 2011, two wholly-owned subsidiaries of Techne, Research and Diagnostic Systems, Inc., a Minnesota corporation (“RDS”), and R&D Systems Europe Ltd. (“RDSE”), a United Kingdom company, entered into a Share Purchase Agreement (the “Agreement”) with the shareholders of Tocris pursuant to which RDS and RDSE collectively acquired all of the outstanding stock of Tocris in exchange for cash. Through the acquisition of Tocris, RDS and RDSE also acquired the following subsidiaries of Tocris (collectively the “Tocris Entities”):

RDS and RDSE acquired the shares of Tocris for total consideration of £75.0 million (approximately $124 million at the exchange rate of £1.00:$1.6528 on April 28, 2011), which consists of approximately £68.0 million ($112.4 million) paid to Tocris shareholders and approximately £7.0 million (approximately $11.6 million) used to pay the Tocris Entities’ external debt at closing. Pursuant to the agreement, £7.5 million of the purchase price paid to Tocris’ shareholders will be held in escrow for 18 months to secure warranty and indemnity obligations of the shareholders contained in the Agreement, and £1.0 million of the purchase price was held in escrow pending confirmation of the final levels of cash, debt and working capital of Tocris at closing. The purchase price may be adjusted post-closing based on these measurements.

Pursuant to the Agreement, the Tocris shareholders, other than the institutional shareholders, are subject to non-compete and non-solicitation obligations for three years following the closing. In connection with the acquisition, Tocris has entered into new employment agreements with key managers of Tocris.

The total purchase price and related preliminary excess total purchase price over fair value of net assets acquired is as follows (in thousands):

Except as discussed in Note 4 below, the carrying value of assets and liabilities in Tocris’ financial statements are considered to be a reasonable estimate of the fair value of those assets and liabilities.

The total purchase price allocation is considered preliminary and is subject to change once Techne receives certain information it believes is necessary to finalize its determination of the fair value of assets acquired and liabilities assumed. Thus the allocation of total purchase price is subject to refinement, and additional adjustments to record the fair value of all assets acquired and liabilities assumed may be required.

Residual goodwill at the date of acquisition varies from goodwill presented in the Pro Forma Financial Information due to changes in the net book value of tangible assets during the period January 1, 2011 through the date of acquisition and different currency exchange rates at December 31, 2010 and the date of acquisition.

4. PRO FORMA ADJUSTMENTS

The Pro Forma Financial Information is based upon the historical consolidated financial statements of Techne and Tocris and certain adjustments which Techne believes are reasonable to give effect to the Tocris acquisition. These adjustments are based upon currently available information and certain assumptions, and therefore the actual adjustments will likely differ from the pro forma adjustments. The Pro Forma Financial Information included herein was prepared using the acquisition method of accounting for the business combination. As discussed above, the purchase price allocation is considered preliminary at this time. However, Techne believes that the preliminary purchase price allocation and other related assumptions utilized in preparing the Pro Forma Financial Information provide a reasonable basis for presenting the pro forma effects of the Tocris acquisition.

Other than those described below, Techne believes there are no adjustments, in any material respects, that need to be made to present the Tocris financial information in accordance with U.S. GAAP, or to align Tocris’ historical accounting policies with Techne’s U.S. GAAP accounting policies.

The adjustments made in preparing the Pro Forma Financial Information are as follows:

(a) Fair Value Acquisition Accounting Adjustments:

For purposes of the pro forma presentation, the following adjustments were made to reflect our preliminary estimate of the fair value of the net assets acquired:

Tocris produces batches of established products in quantities greater than current sales requirements due to economies of scale. The Tocris products have long life-cycles. While the recording of Tocris inventories is not expected to have a continuing impact on cost of goods sold, the sale of inventory held at the date of acquisition will likely be sold over a number of years. It is estimated that the increase in inventories due to fair value adjustments will be charged to Techne’s cost of goods sold approximately as follows: $8.5 million in the first year following the acquisition; $6.2 million in the second year following the acquisition; $4.4 million in the third year following the acquisition; $3.5 million in the fourth year following the acquisition and $2.0 million in the fifth year following the acquisition.

Adjustments were also made to the acquired assets and assumed liabilities of Tocris to align the Tocris financial information prepared using UK Generally Accepted Accounting Practice with Techne’s U.S. GAAP accounting policies. See Note 4(g)-Income Taxes and 4(h)-Reclassifications below.

Goodwill, representing the total excess of the total purchase price over the fair value of the net assets acquired, was approximately $61.4 million at the date of acquisition. This allocation is based on preliminary estimates; the final acquisition cost allocation may differ materially from the preliminary assessment outlined above. Any changes to the initial estimates of the fair value of the assets and liabilities will be allocated to goodwill.

(b) Acquisition Funding

The Tocris acquisition was funded through the use of approximately $124.0 million of cash held by Techne at the time of acquisition. Adjustments were made in the Pro Forma Financial Information to reduce interest income by an estimated amount of interest income that will be lost because of lower invested fund balances. A 1.0% rate of return was assumed based upon recent and projected yields earned by Techne.

(c) Debt

In accordance with the Agreement, at closing, certain cash paid by Techne to acquire Tocris was used to satisfy all outstanding debt and accrued dividends on the preference shares of Tocris.

Adjustments were made in the Pro Forma Financial Information to eliminate interest expense paid by Tocris related to its outstanding debt in the year ended June 30, 2010 and the six months ended December 31, 2010 because, as explained in Note 4(c)(i) above, all such debt was satisfied at the time the acquisition was closed.

(d) Cash held by Tocris

All cash held by Tocris on the date of close was ultimately returned to Tocris shareholders in accordance with the Agreement.

(e) Amortization Expense Related to Acquired Intangible Assets

Acquired finite-lived intangible assets were recorded at their estimated fair value of approximately $48.4 million. The weighted-average useful life of the acquired intangible assets is estimated at 12 years. Adjustments to record estimated amortization expense of $4.1 million and $2.1 million, respectively, were made for the year ended June 30, 2010 and the six month period ended December 30, 2010, and were reflected in the Pro Forma Statement of Income as follows (dollars in thousands):

In addition, adjustments to reverse amortization expense of $732,000 and $362,000, respectively, were made for the year ended June 30, 2010 and the six month period ended December 31, 2010, respectively. These expenses related to Tocris acquisition-related intangible assets that existed prior to the acquisition,and were subsequently eliminated on the acquisition date. These expenses were previously reflected in the Selling, General and Administrative Expense line item by Tocris.

(f) Elimination of Tocris’ Stockholder Equity

An adjustment of $8.8 million to eliminate Tocris’ stockholders’ equity balances was recorded in the Pro Forma Balance Sheet.

(g) Income Taxes

The following pro forma adjustments related to income taxes were made to the Pro Forma Balance Sheet:

The following pro forma adjustments related to income taxes were made to the Pro Forma Statements of Income:
