Indemnification. (a) The Company will indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person, if any, who controls each Underwriter within the meaning of Section 15 of the Act or Section 20 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), from and against any and all losses, claims, liabilities, expenses and damages (including any and all investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding between any of the indemnified parties and any indemnifying parties or between any indemnified party and any third party, or otherwise, or any claim asserted), to which they, or any of them, may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, liabilities, expenses or damages arise out of or are based on any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, the Registration Statement or the Prospectus or any amendment or supplement to the Registration Statement or the Prospectus or the omission or alleged omission to state in such document a material fact required to be stated in it or necessary to make the statements in it not misleading, provided that the Company will not be liable to the extent that such loss, -14- 15 claim, liability, expense or damage arises from the sale of the Shares in the public offering to any person by an Underwriter and is based on an untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to any Underwriter furnished in writing to the Company by the Representatives on behalf of any Underwriter expressly for inclusion in the Registration Statement, any preliminary prospectus or the Prospectus; provided, however, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of an Underwriter from whom the person asserting any such losses, claims, damages or liabilities purchased Shares, or any person controlling such Underwriter, if a copy of the Prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of such Underwriter to such person, if required by law to have been so delivered, at or prior to the written confirmation of the sale of the Shares to such person, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage or liability. (b) Each Underwriter will indemnify and hold harmless the Company, each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, each director of the Company and each officer of the Company who signs the Registration Statement to the same extent as the foregoing indemnity from the Company to each Underwriter, but only insofar as losses, claims, liabilities, expenses or damages arise out of or are based on any untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to any Underwriter furnished in writing to the Company by the Representatives on behalf of such Underwriter expressly for use in the Registration Statement, any preliminary prospectus or the Prospectus. This indemnity will be in addition to any liability that each Underwriter might otherwise have. (c) Any party that proposes to assert the right to be indemnified under this Section 6 will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 6, notify each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but the omission so to notify such indemnifying party will not relieve it from any liability that it may have to any indemnified party under the foregoing provisions of this Section 6 unless, and only to the extent that, such omission results in the forfeiture of substantive rights or defenses by the indemnifying party. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel will -15- 16 be at the expense of such indemnified party unless (i) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (ii) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (iii) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (iv) the indemnifying party has not in fact employed counsel to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges will be reimbursed by the indemnifying party promptly as they are incurred. An indemnifying party will not be liable for any settlement of any action or claim effected without its written consent (which consent will not be unreasonably withheld). No indemnifying party shall, without the prior written consent of each indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters contemplated by this Section 6 (whether or not any indemnified party is a party thereto), unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising or that may arise out of such claim, action or proceeding. (d) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in the foregoing paragraphs of this Section 6 is applicable in accordance with its terms but for any reason is held to be unavailable from the Company or the Underwriters, the Company and the Underwriters will contribute to the total losses, claims, liabilities, expenses and damages (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the Company from persons other than the Underwriters, such as persons who control the Company within the meaning of the Act, officers of the Company who signed the Registration Statement and directors of the Company, who also may be liable for contribution) to which the Company and any one or more of the Underwriters may be subject in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but -16- 17 also the relative fault of the Company, on the one hand, and the Underwriters, on the other, with respect to the statements or omissions which resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Representatives on behalf of the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 6(d) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, liability, expense or damage, or action in respect thereof, referred to above in this Section 6(d) shall be deemed to include, for purpose of this Section 6(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6(d), no Underwriter shall be required to contribute any amount in excess of the underwriting discounts received by it, and no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute as provided in this Section 6(d) are several in proportion to their respective underwriting obligations and not joint. For purposes of this Section 6(d), any person who controls a party to this Agreement within the meaning of the Act will have the same rights to contribution as that party, and each officer of the Company who signed the Registration Statement will have the same rights to contribution as the Company, subject in each case to the provisions hereof. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this Section 6(d), will notify any such party or parties from whom contribution may be sought, but the omission so to notify will not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 6(d). No party will be liable for contribution with respect to any action or claim settled without its written consent (which consent will not be unreasonably withheld). (e) The indemnity and contribution agreements contained in this Section 6 and the representations and warranties of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of the Underwriters, (ii) acceptance of any of the Shares and payment therefor or (iii) any termination of this Agreement. 7. Termination. The obligations of the several Underwriters under this Agreement may be terminated at any time prior to the Closing Date (or, with respect to the Option Shares, on or prior to the Option Closing Date), by notice to the Company from the Representatives, without liability on the part of any Underwriter to the Company, if, prior to delivery and payment for the Shares (or the Option Shares, as the case may be), in the sole judgment of the Representatives, (i) trading in any of the equity securities of the Company -17- 18 shall have been suspended by the Commission, by an exchange that lists the Shares or by the Nasdaq National Market, (ii) trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum or maximum prices shall have been generally established on such exchange, or additional material governmental restrictions, not in force on the date of this Agreement, shall have been imposed upon trading in securities generally by such exchange or by order of the Commission or any court or other governmental authority, (iii) a general banking moratorium shall have been declared by either federal or New York State authorities or (iv) any material adverse change in the financial or securities markets in the United States or in political, financial or economic conditions in the United States or any outbreak or material escalation of hostilities or declaration by the United States of a national emergency or war or other calamity or crisis shall have occurred, the effect of any of which is such as to make it, in the sole judgment of the Representatives, impracticable or inadvisable to market the Shares on the terms and in the manner contemplated by the Prospectus. 8. Substitution of Underwriters. If any one or more of the Underwriters shall fail or refuse to purchase any of the Firm Shares which it or they have agreed to purchase hereunder, and the aggregate number of Firm Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of Firm Shares, the other Underwriters shall be obligated, severally, to purchase the Firm Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase, in the proportions which the number of Firm Shares which they have respectively agreed to purchase pursuant to Section 1 bears to the aggregate number of Firm Shares which all such non-defaulting Underwriters have so agreed to purchase, or in such other proportions as the Representatives may specify; provided that in no event shall the maximum number of Firm Shares which any Underwriter has become obligated to purchase pursuant to Section 1 be increased pursuant to this Section 8 by more than one-ninth of the number of Firm Shares agreed to be purchased by such Underwriter without the prior written consent of such Underwriter. If any Underwriter or Underwriters shall fail or refuse to purchase any Firm Shares and the aggregate number of Firm Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase exceeds one-tenth of the aggregate number of the Firm Shares and arrangements satisfactory to the Representatives and the Company for the purchase of such Firm Shares are not made within 48 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, or the Company for the purchase or sale of any Shares under this Agreement. In any such case either the Representatives or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and in the Prospectus or in any other documents or arrangements may be effected. Any action taken pursuant to this Section 8 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. 9. Miscellaneous. Notice given pursuant to any of the provisions of this Agreement shall be in writing and, unless otherwise specified, shall be mailed or delivered (a) if to the Company, at the office of the Company, 2011 Palomar Airport Road, Carlsbad, California 92009, Attention: Jeffrey D. Witous, or (b) if to the Underwriters, to PaineWebber -18- 19 Incorporated at the offices of PaineWebber Incorporated, 1285 Avenue of the Americas, New York, New York 10019, Attention: Corporate Finance Department. Any such notice shall be effective only upon receipt. Any notice under Section 7 or 8 may be made by telex or telephone, but if so made shall be subsequently confirmed in writing. This Agreement has been and is made solely for the benefit of the several Underwriters, the Company and of the controlling persons, directors and officers referred to in Section 6, and their respective successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. The term "successors and assigns" as used in this Agreement shall not include a purchaser, as such purchaser, of Shares from any of the several Underwriters. With respect to any obligation of the Company hereunder to make any payment, to indemnify for any liability or to reimburse for any expense, the Underwriters (or any other person to whom such payment, indemnification or reimbursement is owed) may pursue the Company with respect thereto. All representations, warranties and agreements of the Company contained herein or in certificates or other instruments delivered pursuant hereto, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or any of their controlling persons and shall survive delivery of and payment for the Shares hereunder. Any action required or permitted to be taken by the Representatives under this Agreement may be taken by them jointly or by PaineWebber Incorporated. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE CONFLICT OF LAWS PRINCIPLES OF SUCH STATE. This Agreement may be signed in two or more counterparts with the same effect as if the signatures thereto and hereto were upon the same instrument. In case any provision in this Agreement shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. The Company and the Underwriters each hereby irrevocably waive any right they may have to a trial by jury in respect of any claim based upon or arising out of this Agreement or the transactions contemplated hereby. This Agreement may not be amended or otherwise modified or any provision hereof waived except by an instrument in writing signed by the Representatives and the Company. -19- 20 Please confirm that the foregoing correctly sets forth the agreement among the Company and the several Underwriters.

As Representatives of the several Underwriters c/o PaineWebber Incorporated 285 Avenue of the Americas New York, New York 10019 Dear Sirs: In consideration of the agreement of the several Underwriters, for which PaineWebber Incorporated and Piper Jaffray Inc. (the "Representatives") intend to act as Representatives, to underwrite a proposed public offering (the "Offering") of the Common Stock, par value $.001 per share (the "Common Stock") of TriTeal Corporation, a Delaware corporation (the "Company"), the undersigned hereby agrees that the undersigned will not, for a period of one hundred eighty (180) days after the commencement of the public offering of such shares, without the prior written consent of PaineWebber Incorporated, offer to sell, sell, contract to sell, grant any option to sell, or otherwise dispose of, or require the Company to file with the Securities and Exchange Commission a registration statement under the Securities Act of 1933 to register, any shares of Common Stock or securities convertible into or exchangeable for Common Stock or warrants or other rights to acquire shares of Common Stock of which the undersigned is now, or may in the future become, the beneficial owner (within the meaning of Rule 13d-3 under the Securities Exchange Act of 1934) (other than pursuant to employee stock option plans or in connection with other employee incentive compensation arrangements) provided, however, that the foregoing shall not prohibit (i) a bona fide gift or gifts so long as such donee or donees thereof agree to be bound by the terms of this Lock-Up Agreement, or (ii) any distribution by a partnership to its partners so long as such partners agree in writing to be bound by the terms of this Lock-Up Agreement. Very truly yours, By -------------------------- Name -------------------------- B-1 25 EXHIBIT C FORM OF OPINION OF COUNSEL TO THE COMPANY The Company is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation and has full corporate power and authority to conduct all the activities conducted by it, to own or lease all the assets owned or leased by it and to conduct its business as described in the Registration Statement and the Prospectus. All of the outstanding shares of Common Stock have been, and the Shares, when paid for by the Underwriters in accordance with the terms of the Agreement, will be, duly authorized, validly issued, fully paid and nonassessable are not subject to any preemptive or similar right under (i) the general corporation law of the State of Delaware, (ii) the Company's certificate of incorporation or bylaws, or (iii) any instrument, document, contract or other agreement filed as an exhibit to the Registration Statement. Except as described in the Registration Statement or the Prospectus, to the best of our knowledge, there is no commitment or arrangement to issue, and there are no outstanding options, warrants or other rights calling for the issuance of, any share of capital stock of the Company or any Subsidiary to any person or any security or other instrument that by its terms is convertible into, exercisable for or exchangeable for capital stock of the Company. No consent, approval, authorization or order of, or any filing or declaration with, any court or governmental agency or body is required in connection with the authorization, issuance, transfer, sale or delivery of the Shares by the Company, in connection with the execution, delivery and performance of the Agreement by the Company or in connection with the taking by the Company of any action contemplated thereby, except such as have been obtained under the Act and the Rules and Regulations and such as may be required under state securities or "Blue Sky" laws or by the bylaws and rules of the NASD in connection with the purchase and distribution by the Underwriters of the Shares to be sold by the Company. The authorized, issued and outstanding capital stock of the Company was as set forth in the Registration Statement and the Prospectus under the caption "Capitalization" as of the date stated therein. The description of the Common Stock contained under the caption "Description of Capital Stock" in the Prospectus is accurate in all material respects and is a fair summary to the extent required by the Act and the Rules and Regulations.. The form of certificate filed as an exhibit to the Registration Statement is in due and proper form and complies with all applicable statutory requirements. C-1 26 The Registration Statement and the Prospectus comply in all material respects as to form with the requirements of the Act and the Rules and Regulations (except that we express no opinion as to financial statements, schedules and other financial and statistical data contained in the Registration Statement or the Prospectus). To the best of our knowledge, any instrument, document, lease, license, contract or other agreement (collectively, "Documents") required to be described or referred to in the Registration Statement or the Prospectus has been properly described or referred to therein to the extent required by the Act and the Rules and Regulations and any Document required to be filed as an exhibit to the Registration Statement has been filed as an exhibit thereto. To the best of our knowledge, except as disclosed in the Registration Statement or the Prospectus, no person or entity has the right to require the registration under the Act of shares of Common Stock or other securities of the Company by reason of the filing or effectiveness of the Registration Statement. There are no legal or governmental proceedings required to be shown in the Prospectus under the Act and the Rules and Regulations. The Company has full corporate power and authority to enter into the Agreement, and the Agreement has been duly authorized, executed and delivered by the Company, is a valid and binding agreement of the Company and, except for the indemnification and contribution provisions thereof, as to which we express no opinion, is enforceable against the Company in accordance with the terms thereof. The execution and delivery by the Company of, and the performance by the Company of its agreements in, the Agreement do not and will not (i) violate the certificate of incorporation or bylaws of the Company, (ii) breach or result in a default under, cause the time for performance of any obligation to be accelerated under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the assets of the Company or the Subsidiary pursuant to the terms of any Document filed as an exhibit to the Registration Statement (iii) breach or otherwise violate any existing obligation of the Company under any court or administrative order, judgment or decree of which we have knowledge or (iv) violate applicable provisions of any statute or regulation in the State of California, of the United States or the Delaware General Corporation Law. The Shares have been duly authorized for quotation on the Nasdaq National Market upon official notice of issuance. We have been advised by the staff of the Commission that the Registration Statement has become effective under the Act and that no order suspending the effectiveness of the Registration Statement has been issued and no proceeding for that purpose has been instituted or is threatened or pending. To our knowledge, there are no actions, suits, proceedings or investigations pending or, to our knowledge, overtly threatened in writing against the Company, before or by any C-2 27 court, governmental agency or arbitrator which (i) seek to challenge the legality or enforceability of the Agreement, (ii) seek to challenge the legality or enforceability of any of the Documents filed, or required to be filed, as exhibits to the Registration Statement, (iii) seek damages or other remedies with respect to any of the Documents filed, or required to be filed, as exhibits to the Registration Statement, (iv) except as set forth in or contemplated by the Registration Statement and the Prospectus, seek money damages in excess of $1,000,000 or seek to impose criminal penalties upon the Company or the Subsidiary of which we have knowledge or (v) seek to enjoin any of the business activities of the Company or the Subsidiary or the transactions described in the Prospectus and of which we have knowledge. In connection with the preparation of the Registration Statement and the Prospectus, we have participated in conferences with officers and representatives of the Company and with its certified public accountants (as you and your counsel have done). As such conferences we have made inquires of such officers, representatives and accountants, and discussed the contents of the Registration Statement and the Prospectus. We have not ourselves independently verified, and accordingly, do not render any opinion upon, the accuracy, completeness or fairness of the Registration Statement or the Prospectus. Based on the foregoing, nothing has come to our attention that causes us to believe that, as of the Effective Date, the Registration Statement contained any untrue statement of a material fact or omitted or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading or that the Prospectus at the time such Prospectus was issued, or at the Closing Date [and the Option Closing Date,] contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances in which they were made, not misleading (except that we express no opinion as to financial statements, schedules and other financial or statistical data contained in the Registration Statement or the Prospectus). The foregoing opinion is subject to the qualification that the enforceability of the Agreement may be: (i) subject to bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors' rights generally; and (ii) subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding at law or in equity), including principles of commercial reasonableness or conscionability and an implied covenant of good faith and fair dealing. This letter is furnished by us solely for your benefit in connection with the transactions referred to in the Agreement and may not be circulated to, or relied upon by, any other person, except that this letter may be relied upon by your counsel in connection with the opinion letter to be delivered to you pursuant to Section 5(f) of the Agreement. In rendering the foregoing opinion, counsel may rely, to the extent they deem such reliance proper, on the opinions (in form and substance reasonably satisfactory to Underwriters' counsel) of other counsel reasonably acceptable to Underwriters' counsel as to matters governed by the laws of jurisdictions other than the United States and the State of C-3 28 Delaware, and as to matters of fact, upon certificates of officers of the Company and of government officials; provided that such counsel shall state that the opinion of any other counsel is in form satisfactory to such counsel. Copies of all such opinions and certificates shall be furnished to counsel to the Underwriters on the Closing Date. C-4
