For purposes of the above calculation, current fair market value of Common Stock shall mean with respect to each share of Common Stock: (i) if traded on a national securities exchange or the Nasdaq National Market (or similar national quotation system), the fair market value shall be deemed to be the closing price (last reported sale) on the day the current fair market value of the securities is being determined; (ii) if traded over-the-counter, the fair market value shall be deemed to be the average of the closing bid or sales price (as applicable) over the thirty calendar day period ending three days before the date of calculation; or (iii) if at any time the Common Stock is not traded as described in (i) or (ii) above, the current fair market value shall be the highest price per share which the Company could obtain from a willing buyer (not a current employee or director) for shares of Common Stock sold by the Company, from authorized but unissued shares, as determined in good faith by its Board of Directors, unless the Company shall become subject to a merger, acquisition or other consolidation pursuant to which the Company is not the surviving party, in which case the fair market value shall be deemed to be the value received by the holders of the Company's Common Stock on a common equivalent basis pursuant to such merger or acquisition. (d) EFFECT OF EXERCISE. This Warrant shall be deemed to have been exercised immediately prior to the close of business on the date of its surrender for exercise as provided above, and the person entitled to receive the Shares issuable upon such exercise shall be treated for all purposes as the holder of record of such shares as of the close of business on such date. As soon as practicable on or after such date, the Company shall issue and deliver to the person or persons entitled to receive the same a certificate or certificates for the number of Shares issuable upon such exercise. (e) TERM. Unless earlier exercised in whole, this Warrant shall terminate and expire as of 5:00 p.m. local California time on November 23, 2002. (f) PARTIAL EXERCISE. This Warrant may be exercised by the holder from time to time as to all or a portion of the Shares subject hereto. In the event that this Warrant is exercised as to only a portion of the Shares subject hereto, the Company will, upon issuance of the Shares so acquired, deliver to the holder a new Warrant representing the remaining Shares subject hereto. 18 (g) VALIDITY. The Warrant and Warrant Shares, when issued, delivered and paid for in accordance with this Agreement, will be duly and validly authorized and issued, fully paid and non-assessable and will not subject the holder thereof to personal liability by reason of being such holder. There are no preemptive rights of any shareholder of the Company, as such, to acquire the Warrant or Warrant Shares. 2. (a) ADJUSTMENT FOR STOCK DIVIDENDS. In case at any time or from time to time on or after the effective date hereof all holders of the Common Stock of the Company (or any shares of stock or other securities at the time receivable upon the exercise of this Warrant) shall have received, or, on or after the record date fixed for the determination of eligible shareholders, shall have become entitled to receive, without payment therefor, other or additional stock of the Company by way of dividend, then and in each case, the Holder of this Warrant shall, upon the exercise hereof, be entitled to receive, in addition to the number of shares of Common Stock receivable thereupon, and without payment of any additional consideration therefor, the amount of such other or additional stock of the Company which such holder would hold on the date of such exercise had it been the holder of record of such Common Stock on the date hereof and had thereafter, during the period from the date hereof to and including the date of such exercise, retained such shares and/or all other additional stock receivable by it as aforesaid during such period, giving effect to all adjustments called for during such period by paragraphs (b) and (c) of this paragraph 2. (b) ADJUSTMENT FOR RECLASSIFICATION, REORGANIZATION OR MERGER. In case of any reclassification or change of the outstanding securities of the Company or of any reorganization of the Company (or any other corporation the stock or securities of which are at the time receivable upon the exercise of this Warrant) on or after the date hereof, or in case, after such date, the Company (or any such other corporation) shall merge with or into another corporation or convey all or substantially all of its assets to another corporation, then and in each such case the holder or this Warrant, upon the exercise hereof at any time after the consummation of such reclassification, change, reorganization, merger or conveyance, shall be entitled to receive, in lieu of the stock or other securities and property receivable upon the exercise hereof prior to such consummation, the stock or other securities or property to which such holder would have been entitled upon such consummation if such holder had exercised this Warrant immediately prior thereto, all subject to further adjustment as provided in paragraphs (a) and (c); in each such case, the terms of this paragraph 2 shall be applicable to the shares of stock or other securities properly receivable upon the exercise of this Warrant after such consummation. (c) STOCK SPLITS AND REVERSE STOCK SPLITS. If at any time on or after the date hereof the Company shall subdivide its outstanding shares of Common Stock into a greater number of shares, the Warrant Price in effect immediately prior to such subdivision shall be proportionately reduced and the number of shares receivable upon exercise of the Warrant shall be proportionately increased; and, conversely, if at any time on or after the date hereof the outstanding number of shares of Common Stock shall be combined into a smaller number of shares, the Warrant Price in effect immediately prior to such combination shall be proportionately increased and the number of shares receivable upon exercise of the Warrant shall be proportionately 19 decreased. 3. (a) CERTAIN INFORMATION RIGHTS. Subject to the provisions of Section 2 above, while a public market exists for the Warrant Shares, the Company agrees to make and keep public information available, as those terms are construed in Rule 144 under the Securities Act of 1933, to file with the commission in a timely manner all periodic reports and to use its best efforts to file other documents required of the Company under the such Act and the Securities Exchange Act of 1934 for applicable time periods under Rule 144. Upon the request of any Holder, the Company will furnish such Holder a copy of such filings. Holder can elect to purchase Shares separately from this Agreement in order to become eligible to receive information provided to all shareholders and can elect to be on Company's non obligatory "courtesy copy" fax list in order to receive corporate (as opposed to commercial or product) press releases along with other interested parties by providing Company with current contact information from time to time. (b) SEC FILINGS. The Company represents and warrants that it has filed all forms, reports and documents required to be filed by it with the Securities and Exchange Commission (the "SEC") (the "COMPANY SEC REPORTS"). The Company SEC Reports, as well as all forms, reports and documents to be filed by the Company with the SEC after the date of the Purchase Agreement, (i) were or will be prepared in accordance with the requirements of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, as the case may be, and the rules and regulations thereunder, (ii) did not at the time they were filed, or will not at the time they are filed, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading, and (iii) did not at the time they were filed, or will not at the time they are filed, omit any documents required to be filed as exhibits thereto. No subsidiary of the Company is required to file any form, report or other document with the SEC. 4. Holder represents and warrants to, and agrees with, the Company, that: (a) PURCHASE FOR OWN ACCOUNT. This Warrant and the Warrant Shares are being acquired for investment for Holder's own account, not as a nominee or agent, and not with a view to the public resale or distribution thereof within the meaning of the Act, and such Holder has no present intention of selling, granting any participation in, or otherwise distributing the same. (b) DISCLOSURE OF INFORMATION. Holder has received or has had full access to all the information it considers necessary or appropriate to make an informed investment decision with respect to the Warrant. Holder has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the Warrant and the Warrant Shares and to obtain additional information necessary to verify any information furnished to Holder or to which Holder had access. Holder acknowledges receipt of Company's most recent periodic reports on forms 10-K and 10-Q as well as all current reports on form 8-K. 20 (c) INVESTMENT EXPERIENCE. Holder understands that the receipt of the Warrants and the purchase of the Warrant Shares involves substantial risk. Holder: (i) has experience as an investor in securities of companies in the development stage and acknowledges that it is able to fend for itself, can bear the economic risk of such investment in the Warrants and Warrant Shares and has such knowledge and experience in financial or business matters that Holder is capable of evaluating the merits and risks of this investment in the Warrants and Warrant Shares and protecting its own interests in connection with this investment and/or (ii) has a preexisting personal or business relationship with the Company and certain of its officers, directors or controlling persons of a nature and duration that enables Holder to be aware of the character, business acumen and financial circumstances of such persons. (d) RESTRICTED SECURITIES. Holder understands that the Warrants and the Warrant Shares are characterized as "restricted securities" under the Securities Act inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under the Securities Act and applicable regulations thereunder such securities may be resold without registration under the Securities Act only in certain limited circumstances. In this connection, Holder represents that Holder is familiar with Rule 144 of the U.S. Securities and Exchange Commission, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act. Holder understands that the Company is under no obligation to register any of the securities sold hereunder except as set forth in Section 11. Holder understands that no public market now exists for the Warrant and that it is uncertain whether a public market will continue to exist for the Warrant Shares. (e) FURTHER LIMITATIONS ON DISPOSITION. Without in any way limiting the representations set forth above, Holder further agrees not to make any disposition of the Warrant in whole or part or all or any portion of the Warrant Shares unless and until: (i) there is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or (ii) (A) Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a statement of the circumstances surrounding the proposed disposition, and (B) Holder shall have furnished the Company, at the expense of Holder or its transferee, with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such securities under the Securities Act. Notwithstanding the provisions of paragraphs (i) and (ii) above, no such registration statement or opinion of counsel shall be required: (1) for any transfer of all or any portion of the Warrant or any Warrant Shares in compliance with SEC Rule 144 or (2) for the transfer by gift, will or intestate succession by Holder to his or her spouse or lineal descendants or ancestors or any trust for any of the foregoing or (3) in connection with a final liquidating distribution to creditors and shareholders of Holder which has been approved by a court with jurisdiction and which is exempt from 21 federal securities laws; PROVIDED that in each of the foregoing cases the transferee agrees in writing to be subject to the terms of this Warrant to the same extent as if the transferee were the original Holder hereunder. (f) LEGENDS. It is understood that the certificates evidencing the Warrant Shares will bear the legends set forth below: (i) THE SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR THE SECURITIES LAWS OF ANY STATE. NO SALE OR OTHER DISPOSITION OR PLEDGE OF THESE SECURITIES MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATING THERETO OR AN EXEMPTION THEREFROM OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT A PROPOSED DISPOSITION OR PLEDGE IS PERMITTED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS OR A NO ACTION LETTER OR INTERPRETIVE OPINION OF THE STAFF OF THE SECURITIES AND EXCHANGE COMMISSION THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE ACT. (ii) Any legend required by the laws of the State of California, including any legend required by the California Department of Corporations and Sections 417 and 418 if the California Corporations Code or any other state securities laws. The legend set forth in (i) above shall be removed by the Company from any certificate evidencing Warrant Shares upon delivery to the Company of an opinion by counsel, reasonably satisfactory to the Company, that a registration statement under the Securities Act is at that time in effect with respect to the legended security or that such security can be freely transferred in a public sale without such a registration statement being in effect and that such transfer will not jeopardize the exemption or exemptions from registration pursuant to which the Company issued the Warrant Shares. (g) PURCHASE AGREEMENT OFFSET. Holder or its predecessor has received the Warrant in consideration in part for various undertakings in the Purchase Agreement. The Company can elect to refuse to authorize the transfer of any Warrant or the issuance of the Warrant Shares until all indemnification and payment obligations to it under the Purchase Agreement (including Exhibit E) are satisfied pursuant to the terms of the Purchase Agreement (other than by discharge in bankruptcy); provided however, that such authorization of transfer or issuance shall not be unreasonably withheld or delayed. This Section 4(g) shall not apply to the proposed transfer of the Warrant or Warrant Shares to any shareholder of the Holder in connection with the liquidation, dissolution and winding up of Holder. 5. OTHER ADJUSTMENTS. Except as provided in paragraph 2, no adjustment on account of dividends or interest on Common Stock will be made upon the exercise hereof. 22 6. NO FRACTIONAL SHARES. No fractional shares of Common Stock will be issued in connection with any subscription hereunder. In lieu of any fractional shares which would otherwise be issuable, the Company shall pay cash equal to the product of such fraction multiplied by the fair market value of one share of Common Stock on the date of exercise, as determined in good faith by the Company's Board of Directors. 7. NO SHAREHOLDER RIGHTS. Until effectively exercised, this Warrant shall not entitle its Holder to any of the rights of a shareholder of the Company. The Company will not, by amendment of its charter or through reorganization, consolidation, merger, dissolution, sale of assets or any other voluntary corporate action, seek to avoid the observance or performance of any of the terms of this Warrant and will at all times reasonably assist in the carrying out of all such terms of the Warrant and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder of this Warrant in accordance with its terms. 8. EXERCISE OF WARRANT. The Holder's ability to exercise this Warrant is subject to the Company having obtained any necessary regulatory approvals prior to such exercise. The Company shall use its best efforts to obtain any such consents after the date hereof. Subject to such approvals, this Warrant (or portion thereof pursuant to Section 10) may be exercised by each registered holder or each of its registered assigns on only four occasions and in minimum increments of 10,000 shares of Common Stock (or any remaining shares of Common Stock subject to this Warrant if the number of shares of Common Stock subject to this Warrant is less than 10,000) by the surrender of this Warrant at the principal office of the Company, accompanied by payment in full of the Warrant Price as described above. A Warrant shall be deemed to have been exercised immediately prior to the close of business on the date of its surrender for exercise as provided above, and the person entitled to receive the shares of Common Stock issuable upon such exercise shall be treated for all purposes as the holder of such Shares of record as of the close of business on such date. As promptly as practicable on or after such date, the Company shall issue and deliver to the person or persons entitled to receive the same, a certificate or certificates for the number of full shares of Common Stock issuable upon such exercise, together with cash in lieu of any fraction of a share as provided above. The Company will at all times reserve and keep available, solely for the issuance and delivery upon the exercise of this Warrant, such shares of Warrant Shares and other stock, securities and property, as from time to time shall be issuable upon the exercise of this Warrant. 9. CERTIFICATE OF ADJUSTMENT. Whenever the Warrant Price is adjusted, as herein provided, upon written request by the holder, the Company shall deliver to the record holder of this Warrant a certificate of an officer of the Company setting forth the (i) Warrant Price after such adjustment, (ii) setting forth a brief statement of the facts requiring such adjustment, and (iii) the kind and amount of stock or other securities or property into which this Warrant shall be exercisable after such adjustment. 10. RESTRICTIONS ON TRANSFER OF WARRANT. This Warrant and all rights hereunder are transferable, in whole or in part, subject to the provisions of Sections 4(d), (e), (f) and (g) above; provided that Holder first offer the Company the opportunity to acquire the Warrant on the same terms as are offered to or by any bona fide third party (each 23 such opportunity expiring if the Company has not accepted the offer in writing within seven business days after notice of the terms). The foregoing right of first refusal shall not apply to the initial Holder's liquidating distribution to its shareholders, nor to any transfer of the Warrant Shares. The terms of this Warrant shall be binding upon the successors and assigns of the holder. 11. PIGGYBACK REGISTRATION AND MARKET STANDOFF AGREEMENT. If: (i) Holder is unable to dispose of its Warrant Shares pursuant to Rule 144 of the SEC (or any successor regulation) within the three months after the notice referred to below; (ii) Holder desires to sell all 50,000 Warrant Shares as soon as practicable (or as many as the Company's investment banker deems prudent); (iii) the Company has conferred registration rights to third parties and such rights have been effectively exercised; and (iv) in the Company's reasonable opinion the inclusion of such Warrant Shares in a registration statement at such time will not prejudice the rights and opportunity of such third parties or result in a breach of the Company's obligations to such third parties; then the Company will notify Holder of the opportunity to participate in such registered offering. Unless Holder confirms its irrevocable election to participate in the registered offering within ten days after receipt of such notice, then Holder will be deemed to have waived its election to participate. If Holder timely elects to participate, then Holder will enter into the same undertakings regarding the registered offering as are applicable to the other selling shareholders (e.g., indemnification). Holder's failure to timely do so will be deemed to waive Holder's right to participate in the registered offering. If Holder does not participate in the registered offering after being offered to participate, the Company is not required to offer further opportunities to participate in such registered offering and such nonparticipation by Holder shall not affect Holder's right to participate in a subsequent registered offering by the Company. In any event, Holder hereby agrees that it shall not, to the extent requested by an underwriter of securities or the Company, sell or otherwise transfer or dispose of any Shares (other than to donees or partners of the holder who agree to be similarly bound) for up to one hundred eighty (180) days following the effective date of a registration statement of the Company filed under the Act; PROVIDED, HOWEVER, that all officers and directors of the Company then holding Common Stock of the Company enter into similar agreements. In order to enforce the foregoing covenant, the Company shall have the right to place restrictive legends on the certificates representing the Shares and to impose stop transfer instructions with respect to the Shares (and the shares or securities of every other person subject to the foregoing restriction) until the end of such period. 12. MISCELLANEOUS. This Warrant shall be governed by the laws of the State of California without giving effect to conflicts of law principles. The headings in this Warrant are for purposes of convenience and reference only, and shall not be deemed to constitute a part hereof. Neither this Warrant nor any term hereof may be changed, waived, discharged or terminated except by an instrument in writing signed by the Company and the registered holder hereof. All notices and other communications from the Company to the holder of this Warrant shall be mailed by first-class registered or certified mail, postage prepaid, to the address furnished to the Company in writing by the last holder of this Warrant who shall have furnished an address to the Company in writing. 24 ISSUED this 23rd day of November, 1998 (the "Effective Date" of this agreement). HOLDER - POST DIGITAL SOFTWARE, INC. RADIUS INC. By: By: ------------------------ ------------------------ 25 ATTACHMENT 1 EXERCISE NOTICE 1. The undersigned hereby elects to purchase _______ shares of the Common Stock of Radius Inc. pursuant to the terms of the attached Warrant and to utilize the net exercise provisions of Section 1(c) of the Warrant (unless payment of the purchase price of such shares in full is made herewith.) 2. Please issue a certificate representing said shares in the name of the undersigned or in such other name as specified below: (Name) (taxpayer ID#) (Address) 3. The undersigned represents it is acquiring the shares solely for its own account and not as a nominee for any other party and not with a view toward the resale or distribution thereof except in compliance with applicable securities laws. (Date) (Signature) 26 Exhibit E Payment Provisions Pursuant to Section 3.1 of the Intangible Asset Purchase Agreement dated November 23, 1998, Buyer will pay Seller payments equal to: (a) $50,000 upon the Closing (the "Initial Payment"); (b) $50,000 upon the earlier of (i) the first anniversary of the Effective Date or (ii) the "Commercialization" of the Software by Buyer; Commercialization means the first commercial shipment of any product of Buyer containing twenty percent or more of the Software object code; (c) "Unit Payments" equal to ten percent of Buyer's "Net Selling Price" (as defined below) for the Software when sold on or licensed for the Apple Macintosh platform; equal to four percent of Buyer's Net Selling Price for the Software when sold on or licensed for the Windows platform; and equal to seven percent of Buyer's Net Selling Price for the Software when sold or licensed as a package for both the Apple Macintosh and Windows platform ; and (d) "Prorated Unit Payments" equal to a percentage of Buyer's Net Selling Price when the Software or certain portions thereof are sold along with other software or technology of Buyer. Prorated Unit Payments will be calculated as follows: (i) the included Software must contain one or more of the "app framework", "paint", "compositor", "particle", "object", and "realtime playback" functionalities of the Software; (ii) for each functionality included, the "Factor" will equal twenty percent (not exceeding one hundred percent), i.e., the presence of two functionalities would yield a Factor of forty percent; (iii) the list price of the standalone Software product and the other Buyer product will be established as "Roto ASP" and "Other Product ASP", respectively; (iv) the applicable Unit Payment percentage will be established as ten, four or seven percent depending on whether the combined product is for use on the Apple Macintosh, Windows platform or both, as applicable; (v) the "ASP Ratio" will then be determined as the Roto ASP divided by the sum of the Roto ASP and the Other Product ASP; (vi) the Prorated Unit Payment for a product sold will then equal the Unit Payment times the Factor times the ASP Ratio. For example, assuming a Roto ASP and a Other Product ASP of $1000 each for the Apple Macintosh platform with a Factor of forty percent, the Prorated Unit Payment will then equal: 10% times $1000 (assuming no netting factors) or $100 [i.e., the non prorated Unit Payment] times the Factor of 40% times the ASP Ratio of fifty percent, or $20. Notwithstanding the foregoing, the total payments, that is the sum of the Initial Payment, the payment upon the first anniversary of the Effective Date or Commericalization, the aggregate Unit Payments and the aggregate Prorated Unit Payments, will not exceed $750,000. Payments are due within 45 days after the end of each quarter for transactions closed during such quarter. NET SELLING PRICE shall mean gross sales revenue and licensing proceeds from all applicable transactions during the applicable quarter excluding, if applicable, sales, use, value added and similar taxes, shipping, insurance and actual discounts, less returns and net deferrals arising from stock balancing, coop advertising, market development and price protection 27 undertakings. Subject to the foregoing, Buyer will calculate and account for gross sales revenue and Net Selling Prices from applicable products (i.e., those containing one or more of the six functionalities of the Software referred to above) in the same manner as such quantities are established for Buyer's other products (i.e., those not containing any one of the six functionalities of the Software referred to above). In the event Buyer assigns (voluntarily or by operation of law) all of its rights in the Software to a third party or any affiliate, then the assignee will be subject to the provisions of this Exhibit E as if the assignee were the Buyer, unless either Buyer or the assignee elects to and does pay the balance of all payment obligations potentially due in the future hereunder (i.e., $750,000 less the sum of all payments previously made). Revenue from the assignment of less than all of Buyer's rights in the Software shall be treated like revenue from the sale of products including the Software or the license of the Software pursuant to paragraph (c) above. All payments under this Agreement will be made in United States currency by bank-to-bank wire transfer to an account designated by Seller, unless otherwise specified by Seller in writing. In the event there are no list prices established for the Software or any other products sold together with the product containing the Software or one or more of the six functionalities, then Buyer will establish deemed list prices in good faith in light of market value and demand. If Seller disputes such deemed prices by notice to Buyer within thirty days after receipt of Buyer's quarterly report, then the parties will cooperate to establish mutually acceptable prices. However, if the parties do not arrive at such mutually acceptable deemed prices within thirty days after notice of the dispute is given, then the parties will submit the matter to an appraiser having extensive experience in setting prices or establishing values for similar products or technology for binding determination. If the parties cannot agree on the selection of an appraiser within such time period, then either party can submit such selection for determination to the American Arbitration Association or any court with jurisdiction. After appointed, the appraiser will request relevant information from each party, make such other inquiries as deemed appropriate and notify each party of the determination and the bases therefore within thirty days. Seller will bear the cost of the appraiser unless the appraiser determines that Buyer's deemed list prices understated Seller's applicable payment obligation for the applicable time period by more than ten percent, in which case Buyer will bear the expense of the appraiser and promptly pay such deficiency to Seller. Buyer reserves the right to reduce payments by any sums due it from Seller (its predecessors and successors) which have not been paid on a net thirty day basis and payment obligations pursuant to the Agreement. Moreover, Buyer can elect to reduce payments by any Losses (as defined in Section 10.1 of the Purchase Agreement) incurred by Buyer (i) in connection with claims by any third party that the Software or its use infringes its rights whether or not Seller had any knowledge of such risk of claim, (ii) in enforcing the Intellectual Property Rights conferred by the Purchase Agreement against third parties who had access to the Software prior to the Effective Date by or through Seller, (iii) as a result of the illegality of Seller's entry into or performance of the Agreement or (iv) as a result of the Stephen Manousos engaging in any conduct prior to the first anniversary of the Effective Date which would have violated the provisions of Section 11 of the Agreement had Seller engaged directly in 28 such conduct. All amounts payable under this Agreement are inclusive of all sales, use, value-added, withholding, and other taxes and duties. Buyer has no obligation to pay such taxes. Seller will pay all taxes and duties assessed in connection with these payments by any authority within or outside of the U.S to Seller under this Agreement. Seller will promptly reimburse Buyer for any and all taxes or duties that Buyer may be required to pay on Seller's behalf in connection with each payment. If any withholding or similar tax must be paid under the laws of any country outside of the U.S. based on the payments due to Seller under this Agreement, then Buyer may elect to pay all such taxes and the amounts payable to Seller under this Agreement will be decreased by the amounts actually so paid. Buyer will provide Seller with written documentation, including but not limited to copies of receipts, of any and all such taxes paid on Seller's behalf in connection with this Agreement. Buyer will maintain complete records regarding the distribution of relevant products during and for two years after the termination Buyer's obligation to make payments under this Agreement and for the duration of any dispute which arises during such time period. Within 45 days after the close of each quarter ending March 31, June 30, September 30 and December 31, Buyer will deliver to Seller a report which will provide all information reasonably necessary for computation and/or confirmation of the payments, if any, due or credited to Seller for such quarterly period. Such reports will identify the relevant products sold, the quantities sold, the list prices of such products, the gross sales revenue therefrom, permissible deductions to arrive at net revenue, any prorations or allocations of net revenue and the payment(s) due less any permissible offsets or credits. An independent certified public accountant selected by Seller (but responsible to both Seller and Buyer as clients) may, upon reasonable notice and during normal business hours, inspect the records of Buyer on which such reports are based. If, upon performing such audit, it is determined that Buyer has underpaid Seller by an amount greater than five percent of the payments due Seller in the period being audited, Buyer will bear all reasonable expenses and costs of such audit in addition to its obligation to make full payment. Such sum will be paid within thirty days after invoicing by Seller. No transaction may be audited more than once, nor more than three years after accrued. An audit may be performed no more frequently than once during any twelve month period. 29
