A.P. PHARMA, INC. - ----------------- NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - ---------------------------------------------------- MARCH 31, 2004 and 2003 (UNAUDITED) - ----------------------------------- (1) Basis of Presentation --------------------- A.P. Pharma, Inc. ("APP", the "Company", "we". "our", or "us") is developing patented polymer-based delivery systems to enhance the safety and effectiveness of pharmaceutical compounds. Projects are currently conducted under feasibility and development arrangements with pharmaceutical and biotechnology companies. New products and technologies under development include bioerodible polymers for injectable and implantable drug delivery. In the opinion of management, the accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments of a normal recurring nature considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2004 are not necessarily indicative of the results that may be expected for the year ending December 31, 2004. The condensed consolidated balance sheet as of December 31, 2003 has been derived from the audited financial statements as of that date. For further information, refer to the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2003. The condensed consolidated financial statements include the financial statements of the Company and its subsidiary, APS Analytical Standards, Inc through the date of sale (February 13, 2003). All significant intercompany balances and transactions have been eliminated in consolidation. Critical Accounting Policies - ---------------------------- We believe there have been no significant changes in our critical accounting policies during the three months ended March 31, 2004 compared to those previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2003 filed with the SEC on March 26, 2004. Use of Estimates - ---------------- The preparation of our financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes. Estimates were made relating to useful lives of fixed assets, valuation allowances, impairment of assets and accruals. Actual results could differ materially from those estimates. Revenue Recognition - ------------------- Our revenue arrangements with multiple deliverables are divided into separate units of accounting if certain criteria are met, including whether the delivered item has stand-alone value to the customer and whether there is objective and reliable evidence of the fair value of the undelivered items. The consideration we receive is allocated among the separate units based on their respective fair values, and the applicable revenue recognition criteria are considered separately for each of the separate units. Advance payments received in excess of amounts earned are classified as deferred revenue until earned. * Royalties Royalties from licenses are based on third-party sales of licensed products or technologies and recorded as earned in accordance with contract terms when third-party results can be reliably determined and collectibility is reasonably assured. Generally, contractually required minimum royalties are recorded ratably throughout the contractual period. Royalties in excess of minimum royalties are recognized as earned when the related product is shipped to the end customer by our licensees based on information provided to us by our licensees. * License Fees We have licensing agreements that generally provide for periodic minimum payments, royalties, and/or non-refundable license fees. These licensing agreements typically require a non-refundable license fee and allow our partners to sell our proprietary products in a defined field or territory for a defined period. The license agreements provide for APP to earn future revenue through royalty payments. These non- refundable license fees are initially reported as deferred revenues and recognized as revenues over the estimated life of the product to which they relate as we have continuing involvement with licensees until the related product is discontinued or the related patents expire, whichever is earlier. Revenue recognized from deferred license fees is classified as license fees in the accompanying consolidated statements of operations. License fees received in connection with arrangements where we have no continuing involvement are recognized as license fees when the amounts are received or when collectibility is assured, whichever is earlier. No such fees were recorded during the three months ended March 31, 2004. A milestone payment is a payment made by a third party or corporate partner to us upon the achievement of a predetermined milestone as defined in a legally binding contract. Milestone payments are recognized as license fees when the milestone event has occurred and we have completed all milestone related services such that the milestone payment is currently due and is non-refundable. No such fees were recorded during the three months ended March 31, 2004. * Contract Revenues Contract revenues also relate to research and development arrangements that generally provide for the company to invoice research and development fees based on full-time equivalent hours for each project. Revenues from these arrangements are recognized as the related development costs are incurred. These revenues approximate the costs incurred. Cash Equivalents and Short-term Investments - ------------------------------------------- We consider all short-term investments in debt securities which have original maturities of less than three months at date of purchase to be cash equivalents. Investments which have original maturities longer than three months are classified as marketable securities in the accompanying balance sheets. Accrued Disposition Costs - ------------------------- Costs relating to disposal of discontinued operations are reported as accrued disposition costs in the accompanying balance sheets. Accrued disposition costs include severance costs and gross profit guarantees. Concentrations of Credit Risk - ----------------------------- Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash equivalents, short-term investments and trade accounts receivable. We invest excess cash in a variety of high grade short-term, interest-bearing securities. This diversification of risk is consistent with our policy to ensure safety of principal and to maintain liquidity. Approximately 79% of the receivables were concentrated with two customers in the pharmaceutical industry as of March 31, 2004. To reduce credit risk, we perform ongoing credit evaluations of our customers' financial conditions. We do not generally require collateral for customers with accounts receivable balances. Segment and Geographic Information - ---------------------------------- Our operations are confined to a single business segment, the design and commercialization of polymer technologies for pharmaceutical and other applications. Substantially all of our revenues are derived from domestic customers. Stock-Based Compensation - ------------------------ We have elected to account for stock-based compensation related to employees using the intrinsic value method. Accordingly, except for stock options issued to non-employees and restricted stock awards to employees and directors, no compensation cost has been recognized for our stock option plans and stock purchase plan. Compensation related to options granted to non- employees is periodically remeasured as earned. In accordance with FAS No. 123, "Accounting for Stock-Based Compensation," as amended by FAS No. 148, "Accounting for Stock-Based Compensation-Transition and Disclosure," we have provided, below, the pro forma disclosures of the effect on net income (loss) and net earnings (loss) per share as if FAS No. 123 had been applied in measuring compensation expense for all periods presented. Three Months Ended March 31, ------------------ 2004 2003 ------------ ----------- (In thousands, except per share amounts) Net earnings (loss), as reported $(2,599) $ 34 Deduct: Stock-based employee compensation expense determined under FAS 123 (104) (132) ------ ------ Pro forma net loss $(2,703) $ (98) ====== ====== Basic earnings (loss) per share as reported $ (0.13) $ * ====== ====== Basic pro forma loss per share $ (0.13) $ ** ====== ====== Diluted earnings (loss) per share as reported $ (0.13) $ * ====== ====== Diluted pro forma loss per share $ (0.13) $ ** ====== ====== * Less than $0.01 per share. ** Less than $(0.01) per share. Fair values of awards granted under the stock option plans and employee stock purchase plan were estimated at grant or purchase dates using Black-Scholes option pricing model. For pro forma disclosure, the estimated fair value of the options is amortized to expense over the vesting period of the options using the straight line method. The multiple option approach is used to value the purchase rights granted under the employee stock purchase plan. We used the following assumptions: Three Months Ended March 31, ------------------ 2004 2003 ---- ---- Expected life in years (from vesting date): Stock options 5 5 Employee stock purchase plan 1.5 - 2 1.5 - 2 Discount rate: Stock options 2.8% 3.8% Employee stock purchase plan 1.47 - 1.82 1.7 - 3.2 Volatility Stock options 65% 102% Employee stock purchase plan 65% - 68% 68% - 69% Expected dividend yield 0% 0% Reclassifications - ----------------- Certain immaterial amounts in the prior year financial statements have been reclassified to conform with the current year presentation. (2) Earnings (Loss) Per Share Information ------------------------------------- Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding. Diluted earnings (loss) per share is computed by dividing net income (loss) by the total of weighted-average number of common shares outstanding and dilutive potential common shares outstanding. The following table sets forth the computation of our basic and diluted earnings (loss) per share (in thousands, except per share amounts): Three Months Ended March 31, ------------------ 2004 2003 ---- ---- Loss from continuing operations $ (2,550) $ (1,798) ======= ======= Net income (loss) (2,599) 34 ======= ======= Shares calculation: Weighted average shares outstanding - basic 20,653 20,475 Effect of dilutive securities: Stock options, employee stock purchase plan and stock to be issued to directors -- 41 ------- ------- Weighted average shares outstanding - diluted 20,653 20,516 ======= ======= Basic earnings (loss) per share: Loss from continuing operations $ (0.12) $ (0.09) ======= ======= Net income (loss) $ (0.13) $ * ======= ======= Diluted earnings (loss) per share: Loss from continuing operations $ (0.12) $ (0.09) ======= ======= Net income (loss) $ (0.13) $ * ======= ======= * Less than $0.01 per share. The following stock options were outstanding during the periods presented, but were not included in the computation of diluted earnings (loss) per share since inclusion of these potentially dilutive securities would have been anti-dilutive for the periods presented (in thousands, except exercise prices): Three Months Ended March 31, ------------------ 2004 2003 ---- ---- Number outstanding 2,197 2,929 Range of exercise prices $1.00 - $10.25 $1.01 - $10.25 (3) Comprehensive Income (Loss) --------------------------- Comprehensive income (loss) for the three months ended March 31, 2004 and March 31, 2003 consists of the following (in thousands): Three Months Ended March 31, ------------------ 2004 2003 ---- ---- Net income (loss) $(2,599) $ 34 Unrealized losses on available-for-sale securities (8) (8) ------ ------ Comprehensive income (loss) $(2,607) $ 26 ====== ====== (4) Commitments ----------- In March 2004 we renegotiated the lease for our facilities. The following is our operating lease commitment as of March 31, 2004. Twelve Months Minimum Ending March 31, Payments ---------------- -------- 2005 $ 316 2006 444 2007 453 2008 463 2009 475 Thereafter 995 ----- Total $3,146 ===== (5) Discontinued Operations ----------------------- We completed the sale of certain assets of our Analytical Standards division as well as certain technology rights for our topical pharmaceutical and cosmeceutical product lines and other assets ("cosmeceutical and toiletry business") in February 2003 and July 2000, respectively. The Analytical Standards division and cosmeceutical and toiletry business are reported as discontinued operations for all periods presented in the accompanying Condensed Consolidated Statements of Operations. Loss from discontinued operations represents the income (loss) attributable to our Analytical Standards division that was sold to GFS Chemicals on February 13, 2003, and changes in estimates for our cosmeceutical and toiletry business that was sold to RP Scherer on July 25, 2000, as follows (in thousands): For the Three Months Ended March 31, -------------------------- 2004 2003 ---- ---- Analytical Standards Division - ----------------------------- Income from Analytical Standards division $ -- $ 9 ---- ---- -- 9 Cosmeceutical and Toiletry Business - ----------------------------------- Recovery of doubtful accounts receivable -- 4 Change in estimates for gross profit guarantees (50) (67) ----- --- (50) (63) ----- --- Total loss from discontinued operations $ (50) $(54) ===== === Basic and diluted loss per common share from discontinued operations excluding the gain on sale of the Analytical Standards and cosmeceutical product lines were less than ($0.01) per share for the three months ended March 31, 2004 and 2003, respectively. Gain on disposition of discontinued operations in the accompanying Consolidated Statement of Operations for the three months ended March 31, 2003 represents the gain on the sale of certain assets of our Analytical Standards division in February 2003. As of March 31, 2004, net assets relating to the discontinued operations include trade receivables of $119,000. Liabilities related to the discontinued operation in the amount of $76,000 include severance costs and accruals for gross profit guarantees. These liabilities are reported as accrued disposition costs in the accompanying consolidated balance sheets. Cash used in discounted operations primarily relates to payments of severance costs to former employees who were terminated as a result of the sale of the Analytical Standards division. Analytical Standards Division - ----------------------------- On February 13, 2003, we completed the sale of our Analytical Standards division to GFS Chemicals, Inc. ("GFS"), a privately held company based in Columbus, Ohio. In this transaction, we received $2.1 million on closing and are entitled to receive royalties on sales of Analytical Standards products for a period of five years at rates ranging from 5% to 15%. The net present value of the guaranteed minimum royalties is included in the gain on disposition of discontinued operations. Royalties in excess of the guaranteed minimum royalties are included in the gain on disposition of discontinued operations when they are realized in accordance with our revenue recognition policy. We recorded additional royalties of $20,000 as income for the 3 months ended March 31, 2004. As a result of the sale of the Analytical Standards division, we recorded severance charges of $210,000 for the year ended December 31, 2003 as a partial offset to the gain on disposition of the Analytical Standards division. In the three months ended March 31, 2004 a reduction to the estimated severance charges of $19,000 was recorded. Approximately $184,000 of these severance charges has been paid through March 31, 2004. Cosmeceutical and Toiletry Business - ----------------------------------- On July 25, 2000, we completed the sale of certain technology rights for our topical pharmaceuticals and cosmeceutical product lines and other assets ("cosmeceutical and toiletry business") to RP Scherer Corporation, a subsidiary of Cardinal Health, Inc. We received $25 million at closing and were entitled to receive further earnout amounts for the subsequent three years up to a maximum of $26.5 million, the amounts of which were dependent on the performance of the business sold. During the first two years of the earnout period, we received an aggregate of $3.8 million. No earnout income was received or reported for the third and final earnout year. Under the terms of the agreement with RP Scherer, we guaranteed a minimum gross profit percentage on RP Scherer's combined sales of products to Ortho Neutrogena and Dermik ("Gross Profit Guaranty"). The guaranty period commenced on July 1, 2000 and ends on the earlier of July 1, 2010 or the end of two consecutive guaranty periods where the combined gross profit on sales to Ortho and Dermik equals or exceeds the guaranteed gross profit. Payments for the Gross Profit Guaranty aggregated $404,000 for the first three guaranty years. We expect the annual Gross Profit Guaranty payments to range from approximately $100,000 to $150,000 for the remainder of the guaranty period. As there is no minimum amount of Gross Profit Guaranty due, no accrual for the guaranty is estimable for future years. (6) Subsequent Events ----------------- On May 5, 2004, we announced our filing of a shelf registration statement with the Securities and Exchange Commission covering up to $15,000,000 of our common stock. The specific terms of this offering under the shelf registration will be established at the time of such offering.

ITEM 2. Management's Discussion and Analysis of Financial Condition ----------------------------------------------------------- and Results of Operations (all dollar amounts rounded to the ------------------------------------------------------------ nearest thousand) ----------------- Except for statements of historical fact, the statements herein are forward-looking and are subject to a number of risks and uncertainties that could cause actual results to differ materially from the statements made. These include, among others, uncertainty associated with timely development, approval, launch and acceptance of new products, establishment of new corporate alliances, progress in research and development programs, and other risks described below or identified from time to time in our Securities and Exchange Commission filings. CRITICAL ACCOUNTING POLICIES AND ESTIMATES The preparation of our financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes. On an ongoing basis, we evaluate our estimates including those related to the useful lives of fixed assets, valuation allowances, impairment of assets, accrued clinical and preclinical expenses and contingencies. Actual results could differ materially from those estimates. We believe there have been no significant changes in our critical accounting policies during the three months ended March 31, 2004 as compared to what was previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2003 filed with the SEC on March 26, 2004. For a description of our critical accounting policies, please refer to our 2003 Annual Report on Form 10-K. On March 31, 2003, the Financial Accounting Standards Board ("FASB") issued an exposure draft of proposed statement titled Share-Based Payment, that addresses the accounting for share-based payment transactions in which an enterprise receives employee services in exchange for (a) equity instruments of the enterprise or (b) liabilities that are based on the fair value of the enterprise's equity instruments or that may be settled by the issuance of such equity instruments. The proposed statement would eliminate the ability to account for share-based compensation transactions using APB Opinion No. 25, Accounting for Stock Issued to Employees, and generally would require instead that such transactions be accounted for using a fair-value-based method. We currently apply the recognition and measurement principles of APB Opinion No. 25. Under this opinion, no stock-based employee compensation expense is charged for options that were granted at an exercise price that was equal to the market value of the underlying common stock on the date of grant. Pro forma information regarding net income and earnings per share is required to be disclosed in the footnotes to our financial statements by Statement of Financial Accounting Standards ("SFAS") No. 123, as amended by SFAS No. 148, as if we had accounted for our employee stock options under the fair value method to that statement. The FASB will invite public comment regarding its proposed statement before issuing a final pronouncement, which is expected later this year. As the proposed statement currently stands, it would become effective with our fiscal quarter ended March 31, 2005. We monitor progress at the FASB and other developments with respect to the general issue of stock-based incentive compensation. In the future, should we expense the value of stock-based incentive compensation, either out of choice or due to new requirements issued by the FASB, and/or decide to alter our current employee compensation programs to provide other benefits in place of incentive stock options, we may have to recognize substantially more compensation expense. This may have an adverse impact on our results of operations. Results of Operations for the Three Months Ended March 31, 2004 and - ------------------------------------------------------------------- 2003 - ---- Our revenues are derived principally from royalties and contract revenues. Under strategic alliance arrangements entered into with certain corporations, we can receive non-refundable upfront fees, milestone payments and royalties based on third party product sales. Royalties for the first quarter of 2004 increased by $122,000 to $1,154,000 from $1,032,000 in the corresponding quarter of the prior year. This increase was due mainly to increased sales of Retin-A Micro(R). We expect royalty revenue to continue to increase in 2004. Contract revenues decreased by $48,000 from $74,000 to $26,000 as a result of fewer collaborative research and development arrangements. Additionally, our feasibility studies frequently experience a period of inactivity while initial results are being evaluated by our collaborators. Research and development expense for the first quarter of 2004 increased by $833,000 from $2,202,000 to $3,035,000 due mainly to the cost of Phase 2 clinical trials of APF112 for the treatment of post-surgical pain as well as preclinical studies of APF530 for the treatment of chemotherapy-induced nausea and vomiting. We expect research and development expense to continue at this level during the second quarter of 2004 while we are conducting human clinical trials for our two product candidates, APF112 and APF530. General and administrative expense for the first quarter of 2004 decreased by $54,000 from $778,000 to $724,000 due to decreased investor relations, rent and depreciation costs, netted with an increase in consultant and professional fees. We expect general and administrative expense to remain essentially flat through the end of the year. Interest income for the first quarter of 2004 decreased by $46,000 to $31,000 from $77,000 due to lower interest rates earned on lower average cash balances. Loss from discontinued operations represents the net contribution (loss) attributable to the Analytical Standards division which was sold to GFS Chemicals, Inc. in February 2003 and the cosmeceutical and toiletries product lines which were sold to RP Scherer Corporation in July 2000. Net loss from discontinued operations totaled $50,000 for the three months ended March 31, 2004, compared with a net loss of $54,000 in the three months ended March 31, 2003. Gain on disposition of discontinued operations of $1,886,000 for the three months ended March 31, 2003 relates to the sale of the Analytical Standards division on February 13, 2003 to GFS Chemicals, Inc., a private company based in Columbus, Ohio. We received $2,149,000 million in cash on the closing date and are entitled to receive royalties on sales varying from 5% to 15% for five years following the closing, with guaranteed minimum annual royalty payments. Capital Resources and Liquidity - ------------------------------- Cash, cash equivalents and marketable securities decreased by $1,740,000 to $7,744,000 at March 31, 2004 from $9,484,000 at December 31, 2003 due to cash used in operating activities. Net cash used in continuing operating activities for the three months ended March 31, 2004 and 2003 was $1,839,000 and $1,580,000, respectively. The increase in net cash used in operating activities was mainly due to increased clinical and preclinical study costs. Net cash provided by investing activities for the three months ended March 31, 2004 and 2003 was $4,082,000 and $2,141,000, respectively. The increase in the cash provided by investing activities was primarily due to the maturities of $5,376,000 of marketable securities, partially offset by the purchases of $1,295,000 of marketable securities. The proceeds received from disposition of discontinued operations received in the three months ended March 31, 2004 of $19,000 relates to the royalties in excess of the guaranteed minimum royalties received from GFS Chemicals compared to $2,149,000 for the three months ended March 31, 2003 which relates to the proceeds received following the sale of our Analytical Standards division. We have funded our operations, including technology and product research and development, primarily through royalties received on sales of Retin-A Micro and Carac, income from collaborative research and development fees, the proceeds received from the sales of our Analytical Standards division and our cosmeceutical and toiletry business, and interest earned on short-term investments. Unless we agree on appropriate terms with a collaborator or partner, our existing cash and cash equivalents, marketable securities, collections of accounts receivable, together with interest income and other revenue-producing activities including royalties, license and option fees and research and development fees, may not be sufficient to meet our cash needs for the next year at the current planned expenditure levels. We will seek additional financing within this timeline through debt or equity financing, the sale of certain assets and technology rights, collaborative arrangements with prospective partners or other arrangements. On May 5, 2004, we announced our filing of a shelf registration statement with the Securities and Exchange Commission which covered up to $15,000,000 of our common stock. If we decide to seek financing through this shelf offering, the specific terms will be established at that time. Our future capital requirements will depend on numerous factors including, among others, royalties from sales of products of third party licensees; our ability to enter into collaborative research and development and licensing agreements; progress of product candidates in preclinical and clinical trials; investment in new research and development programs; time required to gain regulatory approvals; resources that we devote to self-funded products; potential acquisitions of technology, product candidates or businesses; and the costs of defending or prosecuting any patent opposition or litigation necessary to protect our proprietary technology. We may be unable to raise sufficient additional capital when we need it or to raise capital on favorable terms. The sale of equity or convertible debt securities in the future may be dilutive to our stockholders, and debt-financing arrangements may require us to pledge certain assets and enter into covenants that could restrict certain business activities or our ability to incur further indebtedness and may contain other terms that are not favorable to us or our stockholders. If we are unable to obtain adequate funds on reasonable terms, we may be required to curtail operations significantly or to obtain funds by entering into financing, supply or collaboration agreements on unattractive terms. In March 2004 we renegotiated the lease for our facilities. The following is a summary of fixed payments related to certain contractual obligations as of March 31, 2004 (in thousands): Less More than 2 to 3 4 to 5 than Total 1 year years years 5 years ----- ------ ------ ------ ------- Operating Leases $3,146 $316 $897 $938 $995 ----- --- --- --- --- Total $3,146 $316 $897 $938 $995 ===== === === === === ITEM 3. Quantitative and Qualitative Disclosure about Market Risk ---------------------------------------------------------- Since December 31, 2003, there have been no material changes in the Company's market risk exposure. ITEM 4. Controls and Procedures ----------------------- (a) Evaluation of disclosure controls and procedures: We carried out an evaluation, under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operations of our disclosure controls and procedures pursuant to Rule 13a-15(e) and 15(d)-15(e) of the Exchange Act. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that as of March 31, 2004, the end of period covered by this report, our disclosure controls and procedures were effective at the reasonable assurance level to alert them in a timely manner to material information relating to the Company required to be included in our Exchange Act filings. (b) Changes in internal controls: During the quarter ended March 31, 2004, there have been no significant changes in our internal control over financial reporting that materially affected, or are reasonable likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION ----------------- ITEM 1. Legal Proceedings On October 22, 2003, Tristrata Technology, Inc. (Tristrata) filed an amended complaint joining A.P. Pharma, Inc. and other companies as defendants in Tristrata's action first filed July 12, 2002 against Cardinal Health, Inc. and others in the Federal District Court of Delaware. Tristrata's complaint alleges infringement of patents pertaining to alpha-hydroxy acids used in cosmetics. A.P. Pharma answered Tristrata's amended complaint on December 22, 2003. A.P. Pharma is vigorously defending this action. At this early stage of the proceedings we cannot state the amount, if any, which might be recovered by Tristrata from A.P. Pharma. In our opinion, this litigation should not have a material effect on our results of operations or financial condition. ITEM 6.

any commission to Landlord's Broker.  The provisions of this Section
shall survive the expiration or earlier termination of the Amendment
or the Lease.  Landlord hereby agrees to pay such commission, if
any, to which Landlord's Broker is entitled in connection with the
subject matter of this Amendment pursuant to Landlord's separate
written agreement with Landlord's Broker, and agrees that Tenant is
not obligated to pay or fund any amount to Landlord's Broker.  The
provisions of this Section shall survive the expiration or earlier
termination of the Amendment or the Lease.

	Section 11.	Attorneys' Fees.  Each party to this Amendment

any judgment obtained in any such suit or proceeding).

	Section 12.	Effect of Headings.  The titles or headings of
the various parts or sections hereof are intended solely for

and empowered to execute it, and does so as the act of and on behalf
of the party indicated below.

in duplicates or counterparts, or both, and such duplicates or
counterparts together shall constitute but one original of the
Amendment. The parties contemplate that they may be executing
counterparts of this Amendment transmitted by facsimile and agree
and intend that a signature by facsimile machine shall bind the
party so signing with the same effect as though the signature were
