CERTIFICATE OF INCORPORATION PAGE 3 (C) RIGHTS, PREFERENCES AND RESTRICTIONS OF --------------------------------------- SERIES A CONVERTIBLE PREFERRED STOCK ------------------------------------ The rights, preferences, privileges and restrictions granted to and imposed on the Series A Convertible Preferred Stock, par value $0.001 per share, of the Corporation (the "Series A Preferred Stock"), which series shall consist of 2,501,760 shares, are as set forth herein. SECTION 1. DIVIDEND PROVISIONS. (A) The Corporation may (when, as and if ------------------- declared by the Board of Directors of the Corporation) declare and distribute dividends, out of the entire assets and funds of the Corporation legally available for distribution, among the holders of Series A Preferred Stock and the Common Stock, par value $0.001 per share, of the Corporation (the "Common Stock") ratably based on the number of shares of Common Stock held by each such holder (assuming full conversion of all such Series A Preferred Stock); provided, however, that no dividend whatsoever shall be paid, and no - ----------------- distribution shall be made, on any Common Stock unless and until the Series A Preferred Stock shall have been paid in full its pro rata portion of such dividend. All dividends on the Series A Preferred Stock shall be in equal amounts per share. (B) Any dividend or distribution which is declared by the Corporation and payable with assets of the Corporation other than cash shall be governed by the provisions of subsections 3(d)(iii) and 3(e), as applicable, of this Article 4(c). SECTION 2. LIQUIDATION PREFERENCE. (A) In the event of any Liquidating ---------------------- Event (as such term is defined in this subsection 2(a)), the holders of Series A Preferred Stock shall be entitled to receive, prior and in preference to any distribution of any of the assets of the Corporation to the holders of Common Stock by reason of their ownership thereof, an amount per share equal to (i) the Liquidating Preference Price (as such term is defined in this subsection 2(a)) plus (ii) all accrued but unpaid dividends on such Series A Preferred Stock (such amount of accrued but unpaid dividends being referred to herein as the "Unpaid Dividend"). If, upon the occurrence of a Liquidating Event, the assets and funds to be so distributed among the holders of the Series A Preferred Stock shall be insufficient to permit the payment to such holders of the full Liquidating Preference Price and Unpaid Dividend payable under this subsection 2(a), then the entire assets and funds of the Corporation legally available for distribution shall be distributed ratably among such holders of Series A Preferred Stock in proportion to the amount of such Series A Preferred Stock owned by each such holder. Upon the completion of the distribution contemplated by this subsection 2(a) and any other distribution that may be required with respect to series of Preferred Stock that may from time to time come into existence, the remaining assets of the Corporation available for distribution to stockholders shall be distributed among the holders of Common Stock pro rata based on the number of shares of Common Stock held by each such holder. CERTIFICATE OF INCORPORATION PAGE 4 A "Liquidating Event" shall mean (I) the commencement by the Corporation of a voluntary case concerning itself under the bankruptcy laws of the United States, as now or hereafter in effect, or the commencement of an involuntary case against the Corporation with respect to which the petition shall not be controverted within 10 days, or be dismissed within 60 days, after commencement thereof; (II) the appointment of a custodian for, or the taking charge by a custodian of, all or substantially all of the property of the Corporation, or the commencement by the Corporation of any other proceeding under any reorganization, arrangement, adjustment of debt, relief of debtors, dissolution, insolvency or liquidation or similar law of any jurisdiction whether now or hereafter in effect relating to the Corporation, (III) the commencement against the Corporation of any proceeding set forth in the preceding clause (II), which is not controverted within 10 days thereof and dismissed within 60 days after the commencement thereof or (IV) the adjudication of the Corporation insolvent or bankrupt. The "Liquidating Preference Price" shall mean, for each share of Series A Preferred Stock, an amount equal to the quotient of: (X) $24,000,000, divided by (Y) the aggregate number of shares of Series A Preferred Stock issued on the Acquisition Date (as such term is defined in subsection 3(d)(i)(A) of this Article 4(c). (B) In the event of any Corporate Transaction (as such term is defined in subsection 2(c)(i) of this Article 4(c)), the holders of Series A Preferred Stock shall be entitled to receive, prior and in preference to any distribution of any of the assets of the Corporation (and/or the consideration to be received by the holders of Common Stock in respect of a Corporate Transaction) to the holders of Common Stock by reason of their ownership thereof, an amount per share equal to (i) the Original Price (as such term is defined in subsection 3(a) of this Article 4(c)) plus (ii) the Unpaid Dividend. If, upon the occurrence of a Corporate Transaction, the assets and funds to be so distributed among the holders of the Series A Preferred Stock shall be insufficient to permit the payment to such holders of the full Original Price and Unpaid Dividend payable under this subsection 2(b), then the entire assets and funds of the Corporation legally available for distribution shall be distributed ratably among the holders of the Series A Preferred Stock in proportion to the amount of such Series A Preferred Stock owned by each such holder. Upon the completion of the distribution contemplated by this subsection 2(b) and any other distribution that may be required with respect to any other series of Preferred Stock that may from time to time come into existence, the remaining assets of the Corporation legally available for distribution to stockholders shall be distributed among the holders of Common Stock of the Corporation ratably based on the number of shares of Common Stock held by each such holder. CERTIFICATE OF INCORPORATION PAGE 5 (C) (I) For purposes of this Section 2, a "Corporate Transaction" shall be deemed to be the closing (the "Closing") of: (A) the acquisition of the capital stock of the Corporation by another entity by means of any transaction or series of related transactions (including, without limitation, any reorganization, merger or consolidation); or (B) a sale of all or substantially all of the assets of the Corporation, unless, in either case, the Corporation's stockholders of record as constituted immediately prior to such acquisition or sale will, immediately after such acquisition or sale (by virtue of securities issued as consideration for the Corporation's acquisition or sale or otherwise) hold at least 50 percent of the voting power of the surviving or acquiring entity in such acquisition or sale. (II) In any Corporate Transaction, if the consideration received by the Corporation and/or its stockholders is other than cash, its value (for purposes of determining the amount of such consideration to be received by the holders of Series A Preferred Stock under this Section 2) will be deemed its fair market value. Any securities to be received under this Section 2 shall be valued as follows: (A) Securities not subject to investment letter or other similar restrictions on free marketability: (1) If traded on a national securities exchange or through the Nasdaq National Market, the value shall be deemed to be the average of the closing prices of the securities on such exchange over the 30-trading day period ending three days prior to the Closing; (2) If actively traded over-the-counter, the value shall be deemed to be the average of the closing bid or sale prices (whichever is applicable) over the 30-trading day period ending three days prior to the Closing; and (3) If there is no active public market, the value shall be the fair market value thereof, as mutually determined by the Corporation and the holders of at least a majority of the voting power of all then outstanding shares of Preferred Stock; provided, however, if the Corporation and such holders are unable to -------- ------- mutually agree on the fair market value thereof, such fair market value shall be determined by appraisal by the mutual agreement of two reputable commercial appraisers named by the Corporation and such holders, respectively. If such appraisers are unable to CERTIFICATE OF INCORPORATION PAGE 6 mutually determine such fair market value, such appraisers shall name a third appraiser whose determination of such fair market value shall be final. (B) The method of valuation of securities subject to investment letter or other restrictions on free marketability (other than restrictions arising solely by virtue of a stockholder's status as an affiliate or former affiliate) shall be to make an appropriate discount from the market value determined as above in subsection 2(c)(ii)(A)(1), (2) or (3) of this Article 4(c) to reflect the approximate fair market value thereof, as mutually determined by the Corporation and the holders of at least a majority of the voting power of all then outstanding shares of the Series A Preferred Stock in accordance with the valuation procedures provided in subsection 2(c)(ii)(A)(3) of this Article 4(c). (III) In the event the requirements of this subsection 2(c) are not complied with, the Corporation shall forthwith cause the Closing of any Corporate Transaction contemplated to be postponed until such time as the requirements of this Section 2 have been complied with. (IV) The Corporation shall give each holder of record of Series A Preferred Stock written notice of any impending Corporate Transaction not later than 20 days prior to the stockholders' meeting called to approve such Corporate Transaction, or 20 days prior to the Closing of such Corporate Transaction, whichever is earlier, and shall also notify such holders in writing of the final approval of such Corporate Transaction. The first of such notices shall describe the material terms and conditions of the impending Corporate Transaction and the provisions of this Section 2, and the Corporation shall thereafter give such holders prompt notice of any material changes. The Corporate Transaction shall in no event take place sooner than 20 days after the Corporation has given the first notice provided for herein or sooner than 10 days after the Corporation has given notice of any material changes provided for herein; provided, however, such periods may be shortened upon the written -------- ------- consent of the holders of Series A Preferred Stock that are entitled to such notice rights or similar notice rights and that represent at least a majority of the voting power of all then outstanding shares of the Series A Preferred Stock. SECTION 3. CONVERSION. The holders of the Series A Preferred Stock shall ---------- have conversion rights as follows (the "Conversion Rights"): (A) RIGHT TO CONVERT. Each share of Series A Preferred Stock ---------------- shall be convertible, at the option of the holder thereof, at any time after the date of issuance of such share, at the office of the Corporation or any transfer agent for such stock, into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing the Original Price (as defined below in this subsection 3(a)) by the Conversion Price applicable to such share, determined as hereinafter provided, in effect on the date the certificate evidencing such shares of Series A Preferred Stock is surrendered for CERTIFICATE OF INCORPORATION PAGE 7 conversion; provided, however, no such conversion of Series A Preferred Stock -------- ------- pursuant to this subsection 3(a) shall occur unless and until all applicable provisions of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, have been complied with. The initial "Conversion Price" per share for shares of Series A Preferred Stock shall be the Original Price; provided, -------- however, the Conversion Price for the Series A Preferred Stock shall be subject - ------- to adjustment as set forth in subsection 3(d) of this Article 4(c). The "Original Price" shall mean the greater of (I) $16,000,000 divided by the aggregate number of shares of Series A Preferred Stock issued on the Acquisition Date or (II) the average of the closing prices of the Common Stock on the Nasdaq Stock Market or as traded over-the-counter during the 20-trading day period ending 30 trading days after the Acquisition Date. (B) AUTOMATIC CONVERSION. Each share of Series A Preferred -------------------- Stock shall automatically be converted into Common Stock at the Conversion Price at the time in effect for such Series A Preferred Stock immediately upon (except as provided below in subsection 3(c) of this Article 4(c)) the Corporation's sale of Common Stock in a firm commitment underwritten public offering pursuant to a registration statement under the Securities Act of 1933, as amended (the "Securities Act"), the public offering price of which is not less than five times the Conversion Price then in effect with respect to the Series A Preferred Stock and the net proceeds to the Corporation of which are not less than $75,000,000 in the aggregate (net of all discounts, commissions and other expenses allowed, paid or incurred by the Corporation for any underwriting or otherwise in connection therewith); provided, however, no such conversion of -------- ------- Series A Preferred Stock pursuant to this subsection 3(b) shall occur unless and until all applicable provisions of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, have been complied with. (C) MECHANICS OF CONVERSION. Before any holder of Series A ----------------------- Preferred Stock shall be entitled to convert the same into shares of Common Stock, such holder shall surrender the certificate or certificates therefor, duly endorsed, at the office of the Corporation or of any transfer agent for the Series A Preferred Stock, and shall give written notice to the Corporation at its principal corporate office, of the election to convert such Series A Preferred Stock and shall state therein the name or names in which the certificate or certificates for shares of Common Stock are to be issued. The Corporation shall, as soon as practicable thereafter, issue and deliver at such office to such holder of Series A Preferred Stock, or to the nominee or nominees of such holder, a certificate or certificates evidencing the number of shares of Common Stock to which such holder shall be entitled as aforesaid. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the shares of Series A Preferred Stock to be converted, and the person or entity entitled to receive the shares of Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock as of such date. If such conversion is in connection with an underwritten offering of securities registered pursuant to the Securities Act, such conversion shall be conditioned upon the CERTIFICATE OF INCORPORATION PAGE 8 closing with the underwriters of the sale of securities pursuant to such offering, in which event the person or entity entitled to receive Common Stock upon conversion of Series A Preferred Stock shall not be deemed to have converted such Series A Preferred Stock until immediately prior to the closing of such sale of securities. (D) CONVERSION PRICE ADJUSTMENTS OF PREFERRED STOCK FOR --------------------------------------------------- CERTAIN DILUTIVE ISSUANCES, SPLITS AND COMBINATIONS. The Conversion Price of the - --------------------------------------------------- Series A Preferred Stock shall be subject to adjustment from time to time as follows: (I) (A) If the Corporation shall issue, after the date shares of Series A Preferred Stock are first issued (the "Acquisition Date"), any Additional Stock (as such term is defined in subsection 3(d)(ii) of this Article 4(c)) without consideration or for a consideration per share less than the Conversion Price for such Series A Preferred Stock in effect immediately prior to the issuance of such Additional Stock, the Conversion Price for such Series A Preferred Stock in effect immediately prior to each such issuance shall immediately (except as otherwise provided in this subsection 3(d)(i)) be deemed to be adjusted to the quotient of: (X) an amount equal to the sum of: (1) the number of shares of Common Stock outstanding immediately prior to the issuance of such Additional Stock, multiplied by the Conversion Price for such Series A Preferred Stock in effect immediately prior to the issuance of such Additional Stock, plus (2) the aggregate consideration, if any, received by the Corporation for such Additional Stock, divided by (Y) an amount equal to the aggregate number of shares of Common Stock immediately after the issuance of such Additional Stock. (B) No adjustment of the Conversion Price for the Series A Preferred Stock shall be made in an amount less than one cent per share; provided, however, any adjustments which are not required to be made -------- ------- by reason of this sentence shall be carried forward and shall be either taken into account in any subsequent adjustment made prior to three years from the date of the event giving rise to the adjustment being carried forward, or shall be made at the end of three years from the date of the event giving rise to the adjustment being carried forward. Except to the limited extent provided for in subsections 3(d)(i)(E)(3) and (4) of this Article 4(c), no adjustment of such Conversion Price pursuant to this subsection 3(d)(i) shall have the effect of increasing the Conversion Price above the Conversion Price in effect immediately prior to such adjustment. CERTIFICATE OF INCORPORATION PAGE 9 (C) In the case of the issuance of Common Stock for cash, the consideration shall be deemed to be the amount of cash received by the Corporation (net of all discounts, commissions and other expenses allowed, paid or incurred by the Corporation for any underwriting or otherwise in connection with the issuance and sale thereof). (D) In the case of the issuance of the Common Stock for a consideration in whole or in part other than cash, the consideration other than cash shall be deemed to be the fair value thereof as determined in accordance with the valuation procedures provided in subsection 2(c)(ii) of this Article 4(c). (E) In the case of the issuance (whether before, on or after the Acquisition Date) of options to purchase or rights to subscribe for Common Stock, securities by their terms convertible into or exchangeable for Common Stock or options to purchase or rights to subscribe for any such convertible or exchangeable securities, the following provisions shall apply for all purposes of this subsection 3(d)(i) and subsection 3(d)(ii) of this Article 4(c): (1) The aggregate maximum number of shares of Common Stock deliverable upon exercise (to the extent then exercisable) of such options to purchase or rights to subscribe for Common Stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in the manner provided in subsections 3(d)(i)(C) and (D) of this Article 4(c)), if any, received by the Corporation upon the issuance of such options or rights plus the minimum exercise price provided in such options or rights for the Common Stock covered thereby. (2) The aggregate maximum number of shares of Common Stock deliverable upon conversion of or in exchange (to the extent then convertible or exchangeable) for any such convertible or exchangeable securities or upon the exercise of options to purchase or rights to subscribe for such convertible or exchangeable securities (and a subsequent conversion or exchange thereof) shall be deemed to have been issued at the time such securities were issued or such options or rights were issued and for a consideration equal to the consideration, if any, received by the Corporation for any such securities and related options or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the minimum additional consideration, if any, to be received by the Corporation upon the conversion or exchange of such securities or the exercise of any such options or rights (the consideration in each case to be determined in the manner provided in subsections 3(d)(i)(C) and (D) of this Article 4(c)). CERTIFICATE OF INCORPORATION PAGE 10 (3) In the event of any change in the number of shares of Common Stock deliverable or in the consideration payable to the Corporation upon exercise of such options or rights or upon conversion of or in exchange for such convertible or exchangeable securities, including, but not limited to, a change resulting from the antidilution provisions thereof, the Conversion Price of the Series A Preferred Stock, to the extent in any way affected by or computed using such options, rights or securities, shall be recomputed to reflect such change, but no further adjustment shall be made for the actual issuance of Common Stock or any payment of such consideration upon the exercise of any such options or rights or the conversion or exchange of such securities. (4) Upon the expiration of any such options or rights, the termination of any such rights to convert or exchange or the expiration of any options or rights related to such convertible or exchangeable securities, the Conversion Price of the Series A Preferred Stock, to the extent in any way affected by or computed using such options, rights or securities or options or rights related to such securities, shall be recomputed to reflect the issuance of only the number of shares of Common Stock (and convertible or exchangeable securities which remain in effect) actually issued upon the exercise of such options or rights, upon the conversion or exchange of such securities or upon the exercise of the options or rights related to such securities. (5) The number of shares of Common Stock deemed issued and the consideration deemed paid therefor pursuant to subsections 3(d)(i)(E)(1) and (2) of this Article 4(c) shall be appropriately adjusted to reflect any change, termination or expiration of the type described in either subsection 3(d)(i)(E)(3) or (4) of this Article 4(c). (II) "Additional Stock" shall mean any shares of Common Stock issued (or deemed to have been issued pursuant to subsection 3(d)(i)(E) of this Article 4(c)) by the Corporation after the Acquisition Date other than: (A) Common Stock issued pursuant to a transaction described in subsection 3(d)(iii) of this Article 4(c); (B) Common Stock issued on or prior to December 31, 1997, in connection with the acquisition by the Corporation of all or substantially all of the capital stock, equity interest or assets of another entity by means of any transaction or series of related transactions (including, without limitation, any reorganization, merger or consolidation); CERTIFICATE OF INCORPORATION PAGE 11 (C) shares of Common Stock issuable or issued under (i) the Corporation's 1996 Directors' Stock Option Plan or under the Corporation's 1996 Employee Stock Option Plan (collectively, the "Plans"); (D) other incentive issuances to employees, consultants or directors of the Corporation pursuant to stock plans (including the Plans) approved by the stockholders and Board of Directors of the Corporation or pursuant to the exercise of any options which were granted prior to and in existence on the Acquisition Date, but only to the extent the aggregate amount of such issued or issuable shares of Common Stock (including those shares issued under the Plans) do not exceed 1,233,000 shares; or (E) up to 70,000 shares of Common Stock issuable upon exercise of warrants issued or issuable to certain stockholders of American Health Services Corp., a Delaware corporation ("AHS"), on or prior to the Acquisition Date (the "Warrant Shares"). (III) In the event the Corporation should at any time or from time to time after the Acquisition Date fix a record date for the effectuation of a split or subdivision of the outstanding shares of Common Stock or the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in additional shares of Common Stock or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly, additional shares of Common Stock (hereinafter referred to as "Common Stock Equivalents") without payment of any consideration by such holder for the additional shares of Common Stock or the Common Stock Equivalents (including the additional shares of Common Stock issuable upon conversion or exercise thereof), then, as of such record date (or the date of such dividend distribution, split or subdivision if no record date is fixed), the Conversion Price of the Series A Preferred Stock shall be appropriately decreased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be increased in proportion to such increase of the aggregate of shares of Common Stock outstanding and those issuable with respect to such Common Stock Equivalents with the number of shares issuable with respect to Common Stock Equivalents determined from time to time in the manner provided for deemed issuances in subsection 3(d)(i)(E) of this Article 4(c). (IV) If the number of shares of Common Stock outstanding at any time after the Acquisition Date is decreased by a combination of the outstanding shares of Common Stock, then, following the record date of such combination, the Conversion Price for the Series A Preferred Stock shall be appropriately increased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be decreased in proportion to such decrease in outstanding shares. (V) If the Corporation shall issue, during any calendar quarter after the Acquisition Date, any shares of Common Stock (referred to herein, with respect CERTIFICATE OF INCORPORATION PAGE 12 to any such calendar quarter, as "Exercised Shares") upon the exercise of any options or warrants which were granted prior to and in existence on the Acquisition Date (including the 50,000 shares of Common Stock issuable upon exercise of the warrants issued pursuant to Agreements among the Corporation, AHS and holders of preferred stock of AHS dated on or about February 26, 1996), the Conversion Price for such Series A Preferred Stock in effect at the end of such calendar quarter shall immediately be deemed to be adjusted such that the number of shares of Common Stock issuable upon conversion of such Series A Preferred Stock shall thereafter equal the quotient of: (X) an amount equal to the product of: (1) the number of shares of Common Stock issuable upon conversion of the Series A Preferred Stock at the end of such calendar quarter (disregarding the issuance of the Exercised Shares), multiplied by (2) the aggregate number of shares of Common Stock issued and outstanding at the end of such calendar quarter (including the Exercised Shares), divided by (Y) an amount equal to (I) the aggregate number of shares of Common Stock issued and outstanding at the end of such calendar quarter, less (II) the Exercised Shares issued during such fiscal quarter. No adjustment of the Conversion Price for the Series A Preferred Stock shall be made pursuant to this subsection 3(d)(v) more than once per calendar quarter, and then only as of the end of business of such calendar quarter. No adjustment of such Conversion Price pursuant to this subsection 3(d)(c) shall have the effect of increasing the Conversion Price above the Conversion Price in effect immediately prior to such adjustment. (E) OTHER DISTRIBUTIONS. In the event the Corporation shall ------------------- declare a dividend or distribution payable in securities of other persons, evidences of indebtedness issued by the Corporation or other persons, assets (excluding cash dividends) or Common Stock Equivalents not referred to in subsection 3(d)(iii) of this Article 4(c), then, in each such case, the holders of the Series A Preferred Stock shall be entitled to a proportionate share of any such distribution as though they were the holders of the number of shares of Common Stock of the Corporation into which their shares of Series A Preferred Stock are convertible as of the record date fixed for the determination of the holders of Common Stock of the Corporation entitled to receive such dividend or distribution. (F) RECAPITALIZATIONS. If at any time or from time to time ----------------- there shall be a recapitalization of the Common Stock (other than a subdivision, combination or merger or sale of assets transaction provided for elsewhere in this Section 3 or Section 2 of this Article 4(c)) the Corporation shall give the holders of Series A Preferred Stock CERTIFICATE OF INCORPORATION PAGE 13 10 days advance written notice of such recapitalization and provision shall be made so that the holders of the Series A Preferred Stock shall thereafter be entitled to receive upon conversion of the Series A Preferred Stock the number of shares of stock or other securities or property of the Company or otherwise, to which a holder of Common Stock deliverable upon conversion would have been entitled on such recapitalization. In any such case, appropriate adjustment shall be made in the application of the provisions of this Section 3 with respect to the rights of the holders of the Series A Preferred Stock after the recapitalization to the end that the provisions of this Section 3 (including adjustment of the Conversion Price then in effect and the number of shares purchasable upon conversion of the Series A Preferred Stock) shall provide rights to the holders of the Series A Preferred Stock before and after such recapitalization that are as nearly equivalent as may be practicable. (G) NO IMPAIRMENT. The Corporation will not, by amendment of ------------- its Certificate of Incorporation or through any reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Corporation, but will at all times in good faith assist in the carrying out of all the provisions of this Section 3 and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of the holders of the Series A Preferred Stock against impairment. (H) NO FRACTIONAL SHARES. No fractional shares shall be -------------------- issued upon the conversion of any share or shares of the Series A Preferred Stock, and the number of shares of Common Stock to be issued shall be rounded up to a whole share, but in no event shall this provisions obligate the issuer to issue more than 100 shares of Common Stock. Whether or not fractional shares are issuable upon such conversion shall be determined on the basis of the total number of shares of Series A Preferred Stock the holder is at the time converting into Common Stock and the number of shares of Common Stock issuable upon such aggregate conversion. (I) CERTIFICATE AS TO ADJUSTMENTS. Upon the occurrence of ----------------------------- each adjustment or readjustment of the Conversion Price of Series A Preferred Stock pursuant to this Section 3, the Corporation, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to each holder of Series A Preferred Stock a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based.
