In the event of an involuntary conversion pursuant to Section 6.2 hereof, from and after the Involuntary Conversion Date this Note shall only represent the right to receive the shares of Common Stock issuable pursuant to such involuntary conversion, and the Company shall have no obligation under this Note other than to issue such Common Stock.



6.4

EXHIBIT B

SUBORDINATION AGREEMENT

        This Subordination Agreement (this "Agreement") dated                        , is between the undersigned ("Creditor"), and Silicon Valley Bank ("Bank").

Recitals

        A.    Displaytech, Inc. ("Borrower") has requested and/or obtained credit from Bank which may be secured by its assets and property.

        B.    Creditor has extended credit to Borrower and/or may later extend other credit to Borrower.

        C.    To induce Bank to extend credit to Borrower and make further extensions of credit to or for Borrower, or to purchase or extend credit pursuant to any instrument or writing on which Borrower is liable or to grant renewals or extensions of any loan, extension of credit, purchase, or other accommodation Creditor will subordinate: (i) all of Borrower's indebtedness and obligations to Creditor, existing now or later (the "Subordinated Debt") to all of Borrower's indebtedness and Obligations to Bank to the extent set forth herein; and (ii) all of Creditor's security interests, to all of Bank's security interests in the Borrower's property.

THE PARTIES AGREE AS FOLLOWS:

        1.     Creditor subordinates to Bank any security interest or lien that it has in all property and assets of Borrower. Despite attachment or perfection dates of Creditor's security interest and Bank's security interest, Bank's security interest in all assets and property of Borrower is prior to Creditor's security interest.

        2.     All Subordinated Debt payments are subordinated to all Borrower's Obligations to Bank existing now or later, together with collection costs of the Obligations (including attorneys' fees), including, interest accruing after any bankruptcy, reorganization or similar proceeding and all Obligations owing to Bank (the "Senior Debt") subject to Section 3(c) hereof. Defined terms used but not otherwise defined herein shall have the same meanings as set forth in the Senior Debt loan documents.

        3.     Until the Senior Debt is paid in full, Creditor will not:

a)

demand or receive from Borrower (and Borrower will not pay) any part of the Subordinated Debt, by payment, prepayment, or otherwise,



b)

exercise any remedy against any assets of Borrower, or



c)

accelerate the Subordinated Debt, or begin to or participate in any action against Borrower, until all the Senior Debt is paid. However, Creditor may receive regularly scheduled payments of interest that constitute Subordinated Debt (or may receive a payoff of the entire Subordinated Debt if Borrower completes an initial public offering for at least $20,000,000), if an Event of Default (defined in the Senior Debt loan documents) has not occurred, is not continuing and would not exist immediately after payment. Nothing contained herein shall prohibit Creditor from converting any Subordinated Debt into equity securities of Borrower.

        4.     Until the Senior Debt is paid in full, Creditor must deliver to Bank in the form received (except for endorsement or assignment by Creditor) any payment, distribution, security or proceeds it receives on the Subordinated Debt other than according to this Agreement.

        5.     These provisions remain in full force and effect, despite Borrower's insolvency, reorganization or any case or proceeding under any bankruptcy or insolvency law, and Bank's claims against Borrower and Borrower's estate will be fully paid before any payment is made to Creditor, subject to Section 3(c) hereof.

        6.     Until the Senior Debt is paid, Creditor irrevocably appoints Bank as its attorney-in-fact, with power of attorney with power of substitution, in Creditor's name or in Bank's name, for Bank's use and benefit without notice to Creditor, to do the following in any bankruptcy, insolvency or similar proceeding involving Borrower:

        (i)    File any claims for the Subordinated Debt for Creditor if Creditor does not do so at least 30 days before the time to file claims expires, and

        (ii)   Accept or reject any plan of reorganization or arrangement for Creditor and vote Creditor's claims in respect of the Subordinated Debt in any way it chooses.

        7.     Creditor will immediately put a legend on the Subordinated Debt instruments that the instruments are subject to this Agreement. No amendment of the Subordinated Debt documents will modify this Agreement in any way that terminates or impairs the subordination of the Subordinated Debt or the subordination of the security interest or lien that Creditor has in Borrower's property. For example, instruments cannot be amended to (i) increase the interest rate of the Subordinated Debt, or (ii) accelerate payment of principal or interest or any other portion of the Subordinated Debt.

        8.     This Agreement is effective while Borrower owes any amounts to Bank. If after full payment of the Senior Debt, Bank must disgorge any payments made on the Senior Debt, this Agreement and the relative rights and priorities provided in it, will be reinstated as to all disgorged payments as though the payments had not been made, and Creditor will immediately pay Bank all payments received under the Subordinated Debt to the extent the payments would have been prohibited under this Agreement. At any time without notice to Creditor, Bank may take actions it considers appropriate on the Senior Debt such as terminating advances, increasing the principal, extending the time of payment, increasing interest rates, renewing, compromising or otherwise amending any documents affecting the Senior Debt and any collateral securing the Senior Debt, and enforcing or failing to enforce any rights against Borrower or any other person. No action or inaction will impair or otherwise affect Bank's rights under this Agreement. Creditor waives the benefits, if any, of any statutory or common law rule that may permit a subordinating creditor to assert any defenses of a surety or guarantor, or that may give the subordinating creditor the right to require a senior creditor to marshal assets, and Creditor agrees that it shall not assert any such defenses or rights.

        9.     This Agreement binds Creditor, its successors or assigns, and benefits Bank's successors or assigns. This Agreement is for Creditor's and Bank's benefit and not for the benefit of Borrower or any other party. If Borrower is refinancing any of the Senior Debt with a new lender, upon Bank's request of Creditor, Creditor will enter into a new subordination agreement with the new lender on substantially the terms of this Agreement.

        10.   This Agreement may be executed in two or more counterparts, each of which is an original and all of which together constitute one instrument.

        11.   Colorado law governs this agreement without giving effect to conflicts of laws principles. Creditor and Bank submit to the exclusive jurisdiction of the courts in Boulder County State of Colorado. CREDITOR AND BANK EACH WAIVE THEIR RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION FROM THIS AGREEEMNT.

        12.   This Agreement represents the entire agreement about this subject matter, and supersedes prior negotiations or agreements. Creditor is not relying on any representations by Bank in entering into this Agreement. Creditor will keep itself reasonably informed of Borrower's financial and other conditions. This Agreement may be amended only by written instrument signed by Creditor and Bank.

2

        13.   If there is an action to enforce the rights of a party under this Agreement, the party prevailing will be entitled, in addition to other relief, all reasonable costs and expenses, including reasonable attorney's fees, incurred in the action.
