Item 2. Acquisition or Disposition of Assets.

            On December 18, 2000, inSilicon Corporation (the "Company")
completed its acquisition (the "Acquisition") of all of the outstanding
securities of Xentec Inc., a corporation governed by the laws of Canada (the
"Target"), which develops analog and mixed-signal intellectual property. The
Acquisition was made pursuant to a share purchase agreement with each of the
shareholders and optionholders of the Target (the "Acquisition Agreement"), a
copy of which is attached hereto as Exhibit 2.1. In connection with the
Acquisition, inSilicon Corporation will issue an aggregate of up to 1,049,056
shares of the Company's common stock (the "Company Shares") to shareholders of
Target in exchange for such shareholders' shares of capital stock of Target (the
"Target Shares"). At the closing, the Company issued an aggregate of 15,678
Company Shares to Target shareholders who are not Canadian residents, and
inSilcon Canada Ltd., a corporation governed by the laws of Canada and indirect,
wholly-owned subsidiary of the Company ("Exchangeco"), issued an aggregate of
618,378 shares of exchangeable preferred shares (the "Exchangeable Shares") to
the Target's Canadian shareholders. The Exchangeable Shares are convertible on a
one-for-one basis into Company Shares. An aggregate of 149,550 Exchangeable
Shares have been placed in escrow for the purpose of enforcing certain Target
shareholders' indemnification obligations under the Acquisition Agreement. Each
holder of an option to acquire Target Shares agreed to exchange such option for
an option issued by the Company (a "Replacement Option") with substantially
equivalent terms. At the closing, the Company made cash payments in the
aggregate amount of $2,933,000 to certain Target shareholders. The source of the
cash payment was from the Company's existing working capital. After the closing,
Exchangeco will issue up to an aggregate of 415,000 additional Exchangeable
Shares (the "Earnout Shares") pursuant to an earnout provision in the
Acquisition Agreement. The total securities and cash consideration in the
Acquisition was arrived at through arms' length negotiations and took account of
several factors concerning the relative valuations of the Company and the
Target.

            After giving effect to the Acquisition, the aggregate number of
shares of Common Stock outstanding on December 19, 2000, assuming the conversion
of the outstanding Exchangeable Shares, was 14,841,749, excluding the Earnout
Shares.
