         (this "Agreement"), by and between Center Financial
         Corporation, a Connecticut corporation ("Issuer"), and First
         Union Corporation, a North Carolina corporation ("Grantee").

                   WHEREAS, Grantee and Issuer have entered into an
         Agreement and Plan of Mergers, dated as of June 14, 1996 (the
         "Plan"), providing for, among other things, the merger of
         Issuer with and into Grantee, with Grantee being the surviving
         corporation; and

                   WHEREAS, as a condition and inducement to Grantee's
         execution of the Plan, Grantee has required that Issuer agree,
         and Issuer has agreed, to grant Grantee the Option (as
         hereinafter defined);

                   NOW, THEREFORE, in consideration of the foregoing and
         the respective representations, warranties, covenants and
         agreements set forth herein and in the Plan, and intending to
         be legally bound hereby, Issuer and Grantee agree as follows:

                   1.   Defined Terms.  Capitalized terms which are used
         but not defined herein shall have the meanings ascribed to such
         terms in the Plan.

                   2.   Grant of Option.  Subject to the terms and
         conditions set forth herein, Issuer hereby grants to Grantee an
         irrevocable option (the "Option") to purchase up to 2,987,875
         shares (as adjusted as set forth herein, the "Option Shares",
         which shall include the Option Shares before and after any
         transfer of such Option Shares, but in no event shall the
         number of Option Shares for which this Option is exercisable
         exceed 19.9% of the issued and outstanding shares of common
         stock, par value $1.00 per share ("Issuer Common Stock"), of
         Issuer) at a purchase price per Option Share (as adjusted as
         set forth herein, the "Purchase Price") equal to the closing
         price per share of Issuer Common Stock on June 14, 1996, as
         reported by the Nasdaq National Market reporting system (as
         reported in The Wall Street Journal or, if not reported
         therein, another authoritative source).  Each Option Share
         issued upon exercise of the Option shall be accompanied by
         Company Rights as provided in the Company Rights Agreement.





                                       A-1





                   3.   Exercise of Option.

                        (a)  Provided that (i) Grantee or Holder (as
         hereinafter defined), as applicable, shall not be in material
         breach of the agreements or covenants contained in this Agreement
         or the Plan, and (ii) no preliminary or permanent injunction or
         other order against the delivery of shares covered by the Option
         issued by any court of competent jurisdiction in the United States
         shall be in effect, the Holder may exercise the Option, in whole
         or in part, at any time and from time to time following the
         occurrence of a Purchase Event (as hereinafter defined); provided
         that the Option shall terminate and be of no further force or
         effect upon the earliest to occur of (A) the Effective Time,
         (B) termination of the Plan in accordance with the terms thereof
         prior to the occurrence of a Purchase Event or a Preliminary
         Purchase Event other than a termination thereof by Grantee
         pursuant to Section 7.02 of the Plan (but only if the breach of
         Issuer giving rise to such termination was willful) (a termination
         of the Plan by Grantee pursuant to Section 7.02 thereof as a
         result of a willful breach by Issuer being referred to herein as a
         "Default Termination"), (C) 18 months after a Default Termination,
         or (D) 18 months after termination of the Plan (other than a
         Default Termination) following the occurrence of a Purchase Event
         or a Preliminary Purchase Event (other than a Preliminary Purchase
         Event referred to in Section 3(c)(iv), in which case such 18 month
         period shall be reduced to a 12 month period); provided, however,
         that any purchase of shares upon exercise of the Option shall be
         subject to compliance with applicable law.  The term "Holder"
         shall mean the holder or holders of the Option from time to time,
         and which initially is Grantee.  The rights set forth in Section 8
         hereof shall terminate when the right to exercise the Option
         terminates (other than as a result of a complete exercise of the
         Option) as set forth herein.

                        (b)  As used herein, a "Purchase Event" means any
         of the following events:

              or entered into an agreement with any person (other than
              Grantee or any subsidiary of Grantee) to effect an
              Acquisition Transaction.  As used herein, an "Acquisition
              Transaction" shall mean (A) a merger, consolidation or
              similar transaction involving Issuer or any of its
              significant subsidiaries (other than transactions solely
              between Issuer's subsidiaries that are not violative of the
              Plan), (B) the disposition, by sale, lease, exchange or
              otherwise, of assets or deposits of Issuer or any of its
              significant subsidiaries representing in either case 20% or

                                         A-2





              more of the consolidated assets or deposits of Issuer and its
              subsidiaries or (C) the issuance, sale or other disposition
              by Issuer of (including by way of merger, consolidation,
              share exchange or any similar transaction) securities
              representing 20% or more of the voting power of Issuer or any
              of its significant subsidiaries; or

                             (ii) any person (other than Grantee or any
              subsidiary of Grantee) shall have acquired beneficial
              ownership (as such term is defined in Rule 13d-3 promulgated
              under the Exchange Act) of or the right to acquire beneficial
              ownership of, or any "group" (as such term is defined in
              Section 13(d)(3) of the Exchange Act) shall have been formed
              which beneficially owns or has the right to acquire
              beneficial ownership of, 20% or more of the voting power of
              Issuer or any of its significant subsidiaries.

                        (c)  As used herein, a "Preliminary Purchase Event"
         means any of the following events:

                          (i)  any person (other than Grantee or any
              subsidiary of Grantee) shall have commenced (as such term is
              defined in Rule 14d-2 under the Exchange Act) or shall have
              filed a registration statement under the Securities Act, with
              respect to, a tender offer or exchange offer to purchase any
              shares of Issuer Common Stock such that, upon consummation of
              such offer, such person would own or control 15% or more of
              the then outstanding shares of Issuer Common Stock (such an
              offer being referred to herein as a "Tender Offer" or an
              "Exchange Offer," respectively); or

                          (ii)  the holders of Issuer Common Stock shall
              not have approved the Plan by the requisite vote at the
              Meeting, the Meeting shall not have been held or shall have
              been canceled prior to termination of the Plan, or Issuer's
              Board of Directors shall have withdrawn or modified in a
              manner adverse to Grantee the recommendation of Issuer's
              Board of Directors with respect to the Plan, in each case
              after it shall have been publicly announced that any person
              (other than Grantee or any subsidiary of Grantee) shall have
              (A) made, or disclosed an intention to make, a bona fide
              proposal to engage in an Acquisition Transaction,
              (B) commenced a Tender Offer or filed a registration
              statement under the Securities Act with respect to an
              Exchange Offer or (C) filed an application (or given a
              notice), whether in draft or final form, under the Home
              Owners' Loan Act, as amended ("HOLA"), the BHCA, the Bank
              Merger Act, as amended (the "BMA") or the Change in Bank
              Control Act of 1978, as amended (the "CBCA"), for approval to
              engage in an Acquisition Transaction; or

                                         A-3





                        (iii)  any person (other than Grantee or any
              subsidiary of Grantee) shall have made a bona fide proposal
              to Issuer or its stockholders by public announcement, or
              written communication that is or becomes the subject of
              public disclosure, to engage in an Acquisition Transaction;
              or

                        (iv) after a proposal is made by a third party to
              Issuer or its stockholders to engage in an Acquisition
              Transaction, or such third party states its intention to the
              Issuer to make such a proposal if the Plan terminates, Issuer
              shall have breached any representation, warranty, covenant or
              agreement contained in the Plan and such breach would entitle
              Grantee to terminate the Plan under Section 7.02 thereof
              (without regard to the cure period provided for therein
              unless such cure is promptly effected without jeopardizing
              consummation of the Mergers pursuant to the terms of the
              Plan); or

                        (v)  any person (other than Grantee or any
              subsidiary of Grantee) other than in connection with a
              transaction to which Grantee has given its prior written
              consent, shall have filed an application or notice with any
              Regulatory Authority for approval to engage in an Acquisition
              Transaction.

         As used in this Agreement, "person" shall have the meaning
         specified in Sections 3(a)(9) and 13(d)(3) of the Exchange Act.

                        (d)  Issuer shall notify Grantee promptly in
         writing of the occurrence of any Preliminary Purchase Event or
         Purchase Event, it being understood that the giving of such notice
         by Issuer shall not be a condition to the right of Holder to
         exercise the Option.

                        (e)  In the event Holder wishes to exercise the
         Option, it shall send to Issuer a written notice (the date of
         which being herein referred to as the "Notice Date") specifying
         (i) the total number of Option Shares it intends to purchase
         pursuant to such exercise and (ii) a place and date not earlier
         than three business days nor later than 15 business days from the
         Notice Date for the closing (the "Closing") of such purchase (the
         "Closing Date").  If prior notification to or approval of any
         Regulatory Authority is required in connection with such purchase,
         Issuer shall cooperate with the Holder in the filing of the
         required notice of application for approval and the obtaining of
         such approval and the Closing shall occur immediately following
         such regulatory approvals (and any mandatory waiting periods).
         Any exercise of the Option shall be deemed to occur on the Notice
         Date relating thereto.

                                         A-4





                   4.   Payment and Delivery of Certificates.

                        (a)  On each Closing Date, Holder shall (i) pay to
         Issuer, in immediately available funds by wire transfer to a bank
         account designated by Issuer, an amount equal to the Purchase
         Price multiplied by the number of Option Shares to be purchased on
         such Closing Date, and (ii) present and surrender this Agreement
         to the Issuer at the address of the Issuer specified in Section
         12(f).

                        (b)  At each Closing, simultaneously with the
         delivery of immediately available funds and surrender of this
         Agreement as provided in Section 4(a), (i) Issuer shall deliver to
         Holder (A) a certificate or certificates representing the Option
         Shares to be purchased at such Closing, which Option Shares shall
         be free and clear of all Liens and subject to no preemptive
         rights, and (B) if the Option is exercised in part only, an
         executed new agreement with the same terms as this Agreement
         evidencing the right to purchase the balance of the shares of
         Issuer Common Stock purchasable hereunder, and (ii) Holder shall
         deliver to Issuer a letter agreeing that Holder shall not offer to
         sell or otherwise dispose of such Option Shares in violation of
         applicable federal and state law or of the provisions of this
         Agreement.

                        (c)  In addition to any other legend that is
         required by applicable law, certificates for the Option Shares
         delivered at each Closing shall be endorsed with a restrictive
         legend which shall read substantially as follows:

              THE TRANSFER OF THE STOCK REPRESENTED BY THIS
              CERTIFICATE IS SUBJECT TO RESTRICTIONS ARISING UNDER THE
              SECURITIES ACT OF 1933, AS AMENDED, AND PURSUANT TO THE
              TERMS OF A STOCK OPTION AGREEMENT DATED AS OF JUNE 15,
              1996.  A COPY OF SUCH AGREEMENT WILL BE PROVIDED TO THE
              HOLDER HEREOF WITHOUT CHARGE UPON RECEIPT BY THE ISSUER
              OF A WRITTEN REQUEST THEREFOR.

         It is understood and agreed that the portion of the above legend
         relating to the Securities Act shall be removed by delivery of
         substitute certificate(s) without such legend if Holder shall have
         delivered to Issuer a copy of a letter from the staff of the SEC,
         or an opinion of counsel in form and substance reasonably
         satisfactory to Issuer and its counsel, to the effect that such
         legend is not required for purposes of the Securities Act.

                        (d)  Upon the giving by Holder to Issuer of the
         written notice of exercise of the Option provided for under
         Section 3(e), the tender of the applicable purchase price in
         immediately available funds and the tender of this Agreement to
         Issuer, Holder shall be deemed to be the holder of record of the

                                         A-5





         shares of Issuer Common Stock issuable upon such exercise,
         notwithstanding that the stock transfer books of Issuer shall then
         be closed or that certificates representing such shares of Issuer
         Common Stock shall not then be actually delivered to Holder.
         Issuer shall pay all expenses, and any and all United States
         federal, state, and local taxes and other charges that may be
         payable in connection with the preparation, issuance and delivery
         of stock certificates under this Section in the name of Holder or
         its assignee, transferee, or designee.

                        (e)  Issuer agrees (i) that it shall at all times
         maintain, free from preemptive rights, sufficient authorized but
         unissued or treasury shares of Issuer Common Stock so that the
         Option may be exercised without additional authorization of Issuer
         Common Stock after giving effect to all other options, warrants,
         convertible securities and other rights to purchase Issuer Common
         Stock, (ii) that it will not, by charter amendment or through
         reorganization, consolidation, merger, dissolution or sale of
         assets, or by any other voluntary act, avoid or seek to avoid the
         observance or performance of any of the covenants, stipulations or
         conditions to be observed or performed hereunder by Issuer, (iii)
         promptly to take all action as may from time to time be required
         (including (A) complying with all premerger notification,
         reporting and waiting period requirements and (B) in the event
         prior approval of or notice to any Regulatory Authority is
         necessary before the Option may be exercised, cooperating fully
         with Holder in preparing such applications or notices and
         providing such information to such Regulatory Authority as it may
         require) in order to permit Holder to exercise the Option and
         Issuer duly and effectively to issue shares of the Issuer Common
         Stock pursuant hereto, and (iv) promptly to take all action
         provided herein to protect the rights of Holder against dilution.

                   5.   Representations and Warranties of Issuer.  Issuer
         hereby represents and warrants to Grantee (and Holder, if
         different than Grantee) as follows:

                        (a)  Corporate Authority.  Issuer has full
              corporate power and authority to execute and deliver this
              Agreement and to consummate the transactions contemplated
              hereby; the execution and delivery of this Agreement and the
              consummation of the transactions contemplated hereby have
              been duly and validly authorized by the Board of Directors of
              Issuer, and no other corporate proceedings on the part of
              Issuer are necessary to authorize this Agreement or to
              consummate the transactions so contemplated; this Agreement
              has been duly and validly executed and delivered by Issuer.

                        (b)  Shares Reserved for Issuance; Capital Stock.
              Issuer has taken all necessary corporate action to authorize 

                                         A-6





              and reserve and permit it to issue, and at all times from the
              date hereof through the termination of this Agreement in
              accordance with its terms, will have reserved for issuance
              upon the exercise of the Option, that number of shares of
              Issuer Common Stock equal to the maximum number of shares of
              Issuer Common Stock at any time and from time to time
              purchasable upon exercise of the Option, and all such shares,
              upon issuance pursuant to the Option, will be duly
              authorized, validly issued, fully paid and nonassessable, and
              will be delivered free and clear of all Liens (other than
              those created by this Agreement) and not subject to any
              preemptive Rights.

                        (c)  No Violations.  The execution, delivery and
              performance of this Agreement does not or will not, and the
              consummation by Issuer of any of the transactions
              contemplated hereby will not, constitute or result in (A) a
              breach or violation of, or a default under, its articles of
              incorporation or bylaws, or the comparable governing
              instruments of any of its subsidiaries, or (B) a breach or
              violation of, or a default under, any agreement, lease,
              contract, note, mortgage, indenture, arrangement or other
              obligation of it or any of its subsidiaries (with or without
              the giving of notice, the lapse of time or both) or under any
              law, rule, ordinance or regulation or judgment, decree,
              order, award or governmental or non-governmental permit or
              license to which it or any of its subsidiaries is subject,
              that would, in any case give any other person the ability to
              prevent or enjoin Issuer's performance under this Agreement
              in any material respect.

                        (d)  Rights Agreement.  Prior to termination of
              this Agreement in accordance with its terms, Issuer agrees
              not to take any action that would cause First Union to be an
              "Acquiring Person" or an "Adverse Person" as a result of this
              Agreement.

                   6.   Representations and Warranties of Grantee. Grantee
         hereby represents and warrants to Issuer that Grantee has full
         corporate power and authority to enter into this Agreement and,
         subject to obtaining the approvals referred to in this Agreement,
         to consummate the transactions contemplated by this Agreement; the
         execution and delivery of this Agreement and the consummation of
         the transactions contemplated hereby have been duly authorized by
         all necessary corporate action on the part of Grantee; and this
         Agreement has been duly executed and delivered by Grantee.

         Issuer Common Stock by reason of a stock dividend, stock split,

         exercise of the Company Rights or similar transaction, the type
         and number of shares or securities subject to the Option, and the
         Purchase Price therefor, shall be adjusted appropriately, and
         proper provision shall be made in the agreements governing such
         transaction so that Holder shall receive, upon exercise of the
         Option, the number and class of shares or other securities or
         property that Holder would have received in respect of Issuer
         Common Stock if the Option had been exercised immediately prior to
         such event, or the record date therefor, as applicable.  If any
         additional shares of Issuer Common Stock are issued after the date
         of this Agreement (other than pursuant to an event described in
         the first sentence of this Section 7(a), upon exercise of any
         option to purchase Issuer Common Stock outstanding on the date
         hereof or upon conversion into Issuer Common Stock of any
         convertible security of Issuer outstanding on the date hereof),
         the number of shares of Issuer Common Stock subject to the Option
         shall be adjusted so that, after such issuance, it, together with
         any shares of Issuer Common Stock previously issued pursuant
         hereto, equals 19.9% of the number of shares of Issuer Common
         Stock then issued and outstanding, without giving effect to any
         shares subject to or issued pursuant to the Option.   No provision
         of this Section 7 shall be deemed to affect or change, or
         constitute authorization for any violation of, any of the
         covenants or representations in the Plan.

                        (b)  In the event that Issuer shall enter into an
         agreement (i) to consolidate with or merge into any person, other
         than Grantee or one of its subsidiaries, and shall not be the
         continuing or surviving corporation of such consolidation or
         merger, (ii) to permit any person, other than Grantee or one of
         its subsidiaries, to merge into Issuer and Issuer shall be the
         continuing or surviving corporation, but, in connection with such
         merger, the then outstanding shares of Issuer Common Stock shall
         be changed into or exchanged for stock or other securities of
         Issuer or any other person or cash or any other property or the
         outstanding shares of Issuer Common Stock immediately prior to
         such merger shall after such merger represent less than 50% of the
         outstanding shares and share equivalents of the merged company, or
         (iii) to sell or otherwise transfer all or substantially all of
         its assets or deposits to any person, other than Grantee or one of
         its subsidiaries, then, and in each such case, the agreement
         governing such transaction shall make proper provisions so that
         the Option shall, upon the consummation of any such transaction
         and upon the terms and conditions set forth herein, be converted
         into, or exchanged for, an option (the "Substitute Option"), at
         the election of Holder, of either (x) the Acquiring Corporation
         (as hereinafter defined), (y) any person that controls the
         Acquiring Corporation, or (z) in the case of a merger described in
         clause (ii), Issuer (such person being referred to as "Substitute
         Option Issuer"). 

                                         A-8





                        (c)  The Substitute Option shall have the same
         terms as the Option, provided, that, if the terms of the
         Substitute Option cannot, for legal reasons, be the same as the
         Option, such terms shall be as similar as possible and in no event
         less advantageous to Holder.  Substitute Option Issuer shall also
         enter into an agreement with Holder in substantially the same form
         as this Agreement, which shall be applicable to the Substitute
         Option.

                        (d)  The Substitute Option shall be exercisable for
         such number of shares of Substitute Common Stock (as hereinafter
         defined) as is equal to the Assigned Value (as hereinafter
         defined) multiplied by the number of shares of Issuer Common Stock
         for which the Option was theretofore exercisable, divided by the
         Average Price (as hereinafter defined).  The exercise price of
         Substitute Option per share of Substitute Common Stock (the
         "Substitute Option Price") shall then be equal to the Purchase
         Price multiplied by a fraction in which the numerator is the
         number of shares of Issuer Common Stock for which the Option was
         theretofore exercisable and the denominator is the number of
         shares of the Substitute Common Stock for which the Substitute
         Option is exercisable.

                        (e)  The following terms have the meanings
         indicated:

                   (1)  "Acquiring Corporation" shall mean (i) the
              continuing or surviving corporation of a consolidation or
              merger with Issuer (if other than Issuer), (ii) Issuer in a
              merger in which Issuer is the continuing or surviving person,
              or (iii) the transferee of all or substantially all of
              Issuer's assets (or a substantial part of the assets of its
              subsidiaries taken as a whole).

                   (2)  "Substitute Common Stock" shall mean the shares of
              capital stock (or similar equity interest) with the greatest
              voting power in respect of the election of directors (or
              persons similarly responsible for the direction of the
              business and affairs) of the Substitute Option Issuer.

                   (3)  "Assigned Value" shall mean the highest of (w) the
              price per share of Issuer Common Stock at which a Tender
              Offer or an Exchange Offer therefor has been made, (x) the
              price per share of Issuer Common Stock to be paid by any
              third party pursuant to an agreement with Issuer, (y) the
              highest closing price for shares of Issuer Common Stock
              within the six-month period immediately preceding the
              consolidation, merger, or sale in question and (z) in the
              event of a sale of all or substantially all of Issuer's
              assets or deposits an amount equal to (i) the sum of the
              price paid in such sale for such assets (and/or deposits) 

                                         A-9





         and the current market value of the remaining assets of Issuer,
         as determined by a nationally recognized investment banking firm
         selected by Holder divided by (ii) the number of shares of
         Issuer Common Stock outstanding at such time. In the event that
         a Tender Offer or an Exchange Offer is made for Issuer Common
         Stock or an agreement is entered into for a merger or
         consolidation involving consideration other than cash, the value
         of the securities or other property issuable or deliverable in
         exchange for Issuer Common Stock shall be determined by a
         nationally recognized investment banking firm selected by
         Holder.

                   (4)  "Average Price" shall mean the average closing
              price of a share of Substitute Common Stock for the one
              year immediately preceding the consolidation, merger, or
              sale in question, but in no event higher than the closing
              price of the shares of Substitute Common Stock on the day
              preceding such consolidation, merger or sale; provided that
              if Issuer is the issuer of the Substitute Option, the
              Average Price shall be computed with respect to a share of
              common stock issued by Issuer, the person merging into
              Issuer or by any company which controls such person, as
              Holder may elect.

                        (f)  In no event, pursuant to any of the
         foregoing paragraphs, shall the Substitute Option be exercisable
         for more than 19.9% of the aggregate of the shares of Substitute
         Common Stock outstanding prior to exercise of the Substitute
         Option.  In the event that the Substitute Option would be
         exercisable for more than 19.9% of the aggregate of the shares
         of Substitute Common Stock but for the limitation in the first
         sentence of this Section 7(f), Substitute Option Issuer shall
         make a cash payment to Holder equal to the excess of (i) the
         value of the Substitute Option without giving effect to the
         limitation in the first sentence of this Section 7(f) over (ii)
         the value of the Substitute Option after giving effect to the
         limitation in the first sentence of this Section 7(f).  This
         difference in value shall be determined by a nationally-
         recognized investment banking firm selected by Holder.

                        (g)  Issuer shall not enter into any transaction
         described in Section 7(b) unless the Acquiring Corporation and
         any person that controls the Acquiring Corporation assume in
         writing all the obligations of Issuer hereunder and take all
         other actions that may be necessary so that the provisions of
         this Section 7 are given full force and effect (including,
         without limitation, any action that may be necessary so that the
         holders of the other shares of common stock issued by Substitute
         Option Issuer are not entitled to exercise any rights by reason
         of the issuance or exercise of the Substitute Option and the
         shares of Substitute Common Stock are otherwise in no way
         distinguishable from or have lesser economic value (other than

                                       A-10





         any diminution in value resulting from the fact that the
         Substitute Common Stock are restricted securities, as defined in
         Rule 144 under the Securities Act or any successor provision)
         than other shares of common stock issued by Substitute Option
         Issuer).

                   8.   Repurchase at the Option of Holder.  (a)  Subject
         to the last sentence of Section 3(a), at the request of Holder
         at any time commencing upon the first occurrence of a Repurchase
         Event (as defined in Section 8(d)) and ending 12 months
         immediately thereafter, Issuer shall repurchase from Holder
         (i) the Option and (ii) all shares of Issuer Common Stock
         purchased by Holder pursuant hereto with respect to which Holder
         then has beneficial ownership.  The date on which Holder
         exercises its rights under this Section 8 is referred to as the
         "Request Date".  Such repurchase shall be at an aggregate price
         (the "Section 8 Repurchase Consideration") equal to the sum of:

                        (i)  the aggregate Purchase Price paid by Holder
              for any shares of Issuer Common Stock acquired pursuant to
              the Option with respect to which Holder then has beneficial
              ownership;

                        (ii)  the excess, if any, of (x) the Applicable
              Price (as defined below) for each share of Issuer Common
              Stock over (y) the Purchase Price (subject to adjustment
              pursuant to Section 7), multiplied by the number of shares
              of Issuer Common Stock with respect to which the Option has
              not been exercised; and

                       (iii)  the excess, if any, of the Applicable Price
              over the Purchase Price (subject to adjustment pursuant to
              Section 7) paid (or, in the case of Option Shares with
              respect to which the Option has been exercised but the
              Closing Date has not occurred, payable) by Holder for each
              share of Issuer Common Stock with respect to which the
              Option has been exercised and with respect to which Holder
              then has beneficial ownership, multiplied by the number of
              such shares.

                        (b)  If Holder exercises its rights under this
         Section 8, Issuer shall, within 10 business days after the
         Request Date, pay the Section 8 Repurchase Consideration to
         Holder in immediately available funds, and contemporaneously
         with such payment, Holder shall surrender to Issuer the Option
         and the certificates evidencing the shares of Issuer Common
         Stock purchased thereunder with respect to which Holder then has
         beneficial ownership, and Holder shall warrant that it has sole
         record and beneficial ownership of such shares and that the same
         are then free and clear of all Liens.  Notwithstanding the
         foregoing, to the extent that prior notification to or approval 

                                       A-11





         of any Regulatory Authority is required in connection with the
         payment of all or any portion of the Section 8 Repurchase
         Consideration, Holder shall have the ongoing option to revoke its
         request for repurchase pursuant to Section 8, in whole or in part,
         or to require that Issuer deliver from time to time that portion
         of the Section 8 Repurchase Consideration that it is not then so
         prohibited from paying and promptly file the required notice or
         application for approval and expeditiously process the same (and
         each party shall cooperate with the other in the filing of any
         such notice or application and the obtaining of any such
         approval).  If any Regulatory Authority disapproves of any part of
         Issuer's proposed repurchase pursuant to this Section 8, Issuer
         shall promptly give notice of such fact to Holder.  If any
         Regulatory Authority prohibits the repurchase in part but not in
         whole, then Holder shall have the right (i) to revoke the
         repurchase request or (ii) to the extent permitted by such
         Regulatory Authority, determine whether the repurchase should
         apply to the Option and/or Option Shares and to what extent to
         each, and Holder shall thereupon have the right to exercise the
         Option as to the number of Option Shares for which the Option was
         exercisable at the Request Date less the sum of the number of
         shares covered by the Option in respect of which payment has been
         made pursuant to Section 8(a)(ii) and the number of shares covered
         by the portion of the Option (if any) that has been repurchased.
         Holder shall notify Issuer of its determination under the
         preceding sentence within five (5) business days of receipt of
         notice of disapproval of the repurchase. 

                             Notwithstanding anything herein to the
         contrary, all of Holder's rights under this Section 8 shall
         terminate on the date of termination of this Option pursuant to
         Section 3(a).

                        (c)  For purposes of this Agreement, the
         "Applicable Price" means the highest of (i) the highest price per
         share of Issuer Common Stock paid for any such share by the person
         or groups described in Section 8(d)(i), (ii) the price per share
         of Issuer Common Stock received by holders of Issuer Common Stock
         in connection with any merger or other business combination
         transaction described in Section 7(b)(i), 7(b)(ii) or 7(b)(iii),
         or (iii) the highest closing sales price per share of Issuer
         Common Stock quoted on the Nasdaq National Market (or if Issuer
         Common Stock is not quoted on the Nasdaq National Market, the
         highest bid price per share as quoted on the principal trading
         market or securities exchange on which such shares are traded as
         reported by a recognized source chosen by Holder) during the 40
         business days preceding the Request Date; provided, however, that
         in the event of a sale of less than all of Issuer's assets, the
         Applicable Price shall be the sum of the price paid in such sale
         for such assets and the current market value of the remaining
         assets of Issuer as determined by a nationally recognized 

                                        A-12





         investment banking firm selected by Holder, divided by the number
         of shares of the Issuer Common Stock outstanding at the time of
         such sale.  If the consideration to be offered, paid or received
         pursuant to either of the foregoing clauses (i) or (ii) shall be
         other than in cash, the value of such consideration shall be
         determined in good faith by an independent nationally recognized
         investment banking firm selected by Holder and reasonably
         acceptable to Issuer, which determination shall be conclusive for
         all purposes of this Agreement.

                        (d)  As used herein, "Repurchase Event" shall occur
         if (i) any person (other than Grantee or any subsidiary of
         Grantee) shall have acquired beneficial ownership of (as such term
         is defined in Rule 13d-3 promulgated under the Exchange Act), or
         the right to acquire beneficial ownership of, or any "group" (as
         such term is defined under the Exchange Act) shall have been
         formed which beneficially owns or has the right to acquire
         beneficial ownership of, 50% or more of the then outstanding
         shares of Issuer Common Stock, or (ii) any of the transactions
         described in Section 7(b)(i), 7(b)(ii) or 7(b)(iii) shall be
         consummated.

                   9.   Registration Rights.

                        (a)  Demand Registration Rights.  Issuer shall,
         subject to the conditions of Section 9(c) below, if requested by
         any Holder, including Grantee and any permitted transferee
         ("Selling Shareholder"), as expeditiously as possible prepare and
         file a registration statement under the Securities Act if such
         registration is necessary in order to permit the sale or other
         disposition of any or all shares of Issuer Common Stock or other
         securities that have been acquired by or are issuable to the
         Selling Shareholder upon exercise of the Option in accordance with
         the intended method of sale or other disposition stated by the
         Selling Shareholder in such request, including without limitation
         a "shelf" registration statement under Rule 415 under the
         Securities Act or any successor provision, and Issuer shall use
         its best efforts to qualify such shares or other securities for
         sale under any applicable state securities laws.

                        (b)  Additional Registration Rights.  If Issuer at
         any time after the exercise of the Option proposes to register any
         shares of Issuer Common Stock under the Securities Act in
         connection with an underwritten public offering of such Issuer
         Common Stock, Issuer will promptly give written notice to the
         Selling Shareholders of its intention to do so and, upon the
         written request of any Selling Shareholder given within 30 days
         after receipt of any such notice (which request shall specify the
         number of shares of Issuer Common Stock intended to be included in
         such underwritten public offering by the Selling Shareholder),
         Issuer will cause all such shares for which a Selling Shareholder

                                        A-13





         requests participation in such registration, to be so registered
         and included in such underwritten public offering; provided,
         however, that Issuer may elect to not cause any such shares to be
         so registered (i) if the underwriters in good faith object for
         valid business reasons, or (ii) in the case of a registration
         solely to implement an employee benefit plan or a registration
         filed on Form S-4 of the Securities Act or any successor Form;
         provided, further, however, that such election pursuant to (i) may
         only be made two times.  If some but not all the shares of Issuer
         Common Stock, with respect to which Issuer shall have received
         requests for registration pursuant to this Section 9(b), shall be
         excluded from such registration, Issuer shall make appropriate
         allocation of shares to be registered among the Selling
         Shareholders desiring to register their shares pro rata in the
         proportion that the number of shares requested to be registered by
         each such Selling Shareholder bears to the total number of shares
         requested to be registered by all such Selling Shareholders then
         desiring to have Issuer Common Stock registered for sale.

                        (c)  Conditions to Required Registration.  Issuer
         shall use all reasonable efforts to cause each registration
         statement referred to in Section 9(a) above to become effective
         and to obtain all consents or waivers of other parties which are
         required therefor and to keep such registration statement
         effective, provided, however, that Issuer may delay any
         registration of Option Shares required pursuant to Section 9(a)
         above for a period not exceeding 90 days provided Issuer shall in
         good faith determine that any such registration would adversely
         affect an offering or contemplated offering of other securities by
         Issuer, and Issuer shall not be required to register Option Shares
         under the Securities Act pursuant to Section 9(a) above:

                              (i)  prior to the earliest of (a) termination
              of the Plan pursuant to Article VII thereof, (b) failure to
              obtain the requisite stockholder approval pursuant to Section
              6.01 of Article VI of the Plan, and (c) a Purchase Event or a
              Preliminary Purchase Event;

                             (ii)  on more than one occasion during any
              calendar year;

                             (iii)  within 90 days after the effective date
              of a registration referred to in Section 9(b) above pursuant
              to which the Selling Shareholder or Selling Shareholders
              concerned were afforded the opportunity to register such
              shares under the Securities Act and such shares were
              registered as requested; and

                             (iv)  unless a request therefor is made to
              Issuer by Selling Shareholders that hold at least 25% or

                                        A-14





              more of the aggregate number of Option Shares (including
              shares of Issuer Common Stock issuable upon exercise of the
              Option) then outstanding.

                        In addition to the foregoing, Issuer shall not be re-
         quired to maintain the effectiveness of any registration statement
         after the expiration of nine months from the effective date of such
         registration statement.  Issuer shall use all reasonable efforts to
         make any filings, and take all steps, under all applicable state se-
         curities laws to the extent necessary to permit the sale or other
         disposition of the Option Shares so registered in accordance with
         the intended method of distribution for such shares; provided,
         however, that Issuer shall not be required to consent to general
         jurisdiction or qualify to do business in any state where it is not
         otherwise required to so consent to such jurisdiction or to so
         qualify to do business.

                        (d)  Expenses.  Except where applicable state law
         prohibits such payments, Issuer will pay all expenses (including
         without limitation registration fees, qualification fees, blue sky
         fees and expenses (including the fees and expenses of counsel),
         legal expenses, including the reasonable fees and expenses of one
         counsel to the holders whose Option Shares are being registered,
         printing expenses and the costs of special audits or "cold comfort"
         letters, expenses of underwriters, excluding discounts and
         commissions but including liability insurance if Issuer so desires
         or the underwriters so require, and the reasonable fees and expenses
         of any necessary special experts) in connection with each
         registration pursuant to Section 9(a) or 9(b) above (including the
         related offerings and sales by holders of Option Shares) and all
         other qualifications, notifications or exemptions pursuant to
         Section 9(a) or 9(b) above.

                        (e)  Indemnification.  In connection with any regis-
         tration under Section 9(a) or 9(b) above Issuer hereby indemnifies
         the Selling Shareholders, and each underwriter thereof, including
         each person, if any, who controls such holder or underwriter within
         the meaning of Section 15 of the Securities Act, against all ex-
         penses, losses, claims, damages and liabilities caused by any
         untrue, or alleged untrue, statement of a material fact contained in
         any registration statement or prospectus or notification or offering
         circular (including any amendments or supplements thereto) or any
         preliminary prospectus, or caused by any omission, or alleged omis-
         sion, to state therein a material fact required to be stated therein
         or necessary to make the statements therein not misleading, except
         insofar as such expenses, losses, claims, damages or liabilities of
         such indemnified party are caused by any untrue statement or alleged
         untrue statement that was included by Issuer in any such
         registration statement or prospectus or notification or offering

                                         A-15





         circular (including any amendments or supplements thereto) in
         reliance upon and in conformity with, information furnished in
         writing to Issuer by such indemnified party expressly for use
         therein, and Issuer and each officer, director and controlling
         person of Issuer shall be indemnified by such Selling
         Shareholders, or by such underwriter, as the case may be, for
         all such expenses, losses, claims, damages and liabilities
         caused by any untrue, or alleged untrue, statement, that was
         included by Issuer in any such registration statement or
         prospectus or notification or offering circular (including any
         amendments or supplements thereto) in reliance upon, and in
         conformity with, information furnished in writing to Issuer by
         such holder or such underwriter, as the case may be, expressly
         for such use.

                        Promptly upon receipt by a party indemnified
         under this Section 9(e) of notice of the commencement of any
         action against such indemnified party in respect of which
         indemnity or reimbursement may be sought against any
         indemnifying party under this Section 9(e), such indemnified
         party shall notify the indemnifying party in writing of the
         commencement of such action, but the failure so to notify the
         indemnifying party shall not relieve it of any liability which
         it may otherwise have to any indemnified party under this
         Section 9(e).  In case notice of commencement of any such action
         shall be given to the indemnifying party as above provided, the
         indemnifying party shall be entitled to participate in and, to
         the extent it may wish, jointly with any other indemnifying
         party similarly notified, to assume the defense of such action
         at its own expense, with counsel chosen by it and satisfactory
         to such indemnified party.  The indemnified party shall have the
         right to employ separate counsel in any such action and
         participate in the defense thereof, but the fees and expenses of
         such counsel (other than reasonable costs of investigation)
         shall be paid by the indemnified party unless (i) the
         indemnifying party either agrees to pay the same, (ii) the
         indemnifying party fails to assume the defense of such action
         with counsel satisfactory to the indemnified party, or (iii) the
         indemnified party has been advised by counsel that one or more
         legal defenses may be available to the indemnifying party that
         may be contrary to the interest of the indemnified party, in
         which case the indemnifying party shall be entitled to assume
         the defense of such action notwithstanding its obligation to
         bear fees and expenses of such counsel.  No indemnifying party
         shall be liable for any settlement entered into without its
         consent, which consent may not be unreasonably withheld.

                        If the indemnification provided for in this
         Section 9(e) is unavailable to a party otherwise entitled to be
         indemnified in respect of any expenses, losses, claims, damages
         or liabilities referred to herein, then the indemnifying party,
         in lieu of indemnifying such party otherwise entitled to be 

                                       A-16





         indemnified, shall contribute to the amount paid or payable by
         such party to be indemnified as a result of such expenses,
         losses, claims, damages or liabilities in such proportion as is
         appropriate to reflect the relative benefits received by Issuer,
         the Selling Shareholders and the underwriters from the offering
         of the securities and also the relative fault of Issuer, the
         Selling Shareholders and the underwriters in connection with the
         statements or omissions which resulted in such expenses, losses,
         claims, damages or liabilities, as well as any other relevant
         equitable considerations.  The amount paid or payable by a party
         as a result of the expenses, losses, claims, damages and
         liabilities referred to above shall be deemed to include any
         legal or other fees or expenses reasonably incurred by such party
         in connection with investigating or defending any action or
         claim; provided, however, that in no case shall any Selling
         Shareholder be responsible, in the aggregate, for any amount in
         excess of the net offering proceeds attributable to its Option
         Shares included in the offering.  No person guilty of fraudulent
         misrepresentation (within the meaning of Section 11(f) of the
         Securities Act) shall be entitled to contribution from any person
         who was not guilty of such fraudulent misrepresentation.  Any
         obligation by any holder to indemnify shall be several and not
         joint with other holders.

                        In connection with any registration pursuant to
         Section 9(a) or 9(b) above, Issuer and each Selling Shareholder
         (other than Grantee) shall enter into an agreement containing the
         indemnification provisions of this Section 9(e).

                        (f)  Miscellaneous Reporting.  Issuer shall comply
         with all reporting requirements and will do all such other things
         as may be necessary to permit the expeditious sale at any time of
         any Option Shares by the Selling Shareholders thereof in
         accordance with and to the extent permitted by any rule or
         regulation promulgated by the SEC from time to time, including,
         without limitation, Rule 144A.  Issuer shall at its expense
         provide the Selling Shareholders with any information necessary
         in connection with the completion and filing of any reports or
         forms required to be filed by them under the Securities Act or
         the Exchange Act, or required pursuant to any state securities
         laws or the rules of any stock exchange.

                        (g)  Issue Taxes.  Issuer will pay all stamp taxes
         in connection with the issuance and the sale of the Option Shares
         and in connection with the exercise of the Option, and will save
         the Selling Shareholders harmless, without limitation as to time,
         against any and all liabilities, with respect to all such taxes.

                    10. Quotation; Listing.  If Issuer Common Stock or any
         other securities to be acquired in connection with the exercise
         of the Option are then authorized for quotation or trading or

                                        A-17





         listing on the Nasdaq National Market or any securities exchange,
         Issuer, upon the request of Holder, will promptly file an
         application, if required, to authorize for quotation or trading
         or listing the shares of Issuer Common Stock or other securities
         to be acquired upon exercise of the Option on the Nasdaq National
         Market or such other securities exchange and will use its best
         efforts to obtain approval, if required, of such quotation or
         listing as soon as practicable.

                    11. Division of Option.  This Agreement (and the
         Option granted hereby) are exchangeable, without expense, at the
         option of Holder, upon presentation and surrender of this
         Agreement at the principal office of Issuer for other Agreements
         providing for Options of different denominations entitling the
         holder thereof to purchase in the aggregate the same number of
         shares of Issuer Common Stock purchasable hereunder.  The terms
         "Agreement" and "Option" as used herein include any other
         Agreements and related Options for which this Agreement (and the
         Option granted hereby) may be exchanged.  Upon receipt by Issuer
         of evidence reasonably satisfactory to it of the loss, theft,
         destruction or mutilation of this Agreement, and (in the case of
         loss, theft or destruction) of reasonably satisfactory
         indemnification, and upon surrender and cancellation of this
         Agreement, if mutilated, Issuer will execute and deliver a new
         Agreement of like tenor and date.  Any such new Agreement
         executed and delivered shall constitute an additional contractual
         obligation on the part of Issuer, whether or not the Agreement so
         lost, stolen, destroyed or mutilated shall at any time be
         enforceable by anyone.

                   12.  Miscellaneous.

                        (a)  Expenses.   Each of the parties hereto shall
         bear and pay all costs and expenses incurred by it or on its
         behalf in connection with the transactions contemplated
         hereunder, including fees and expenses of its own financial
         consultants, investment bankers, accountants and counsel.

                        (b)  Waiver and Amendment.  Any provision of this
         Agreement may be waived at any time by the party that is entitled
         to the benefits of such provision.  This Agreement may not be
         modified, amended, altered or supplemented except upon the
         execution and delivery of a written agreement executed by the
         parties hereto.

                        (c)  Entire Agreement: No Third-Party
         Beneficiaries; Severability.  This Agreement, together with the
         Plan and the other documents and instruments referred to herein
         and therein, between Grantee and Issuer (i) constitutes the
         entire agreement and supersedes all prior agreements and
         understandings, both written and oral, between the parties with 

                                        A-18





         respect to the subject matter hereof and (ii) is not intended to
         confer upon any person other than the parties hereto (other than
         the indemnified parties under Section 9(e) and any transferees of
         the Option Shares or any permitted transferee of this Agreement
         pursuant to Section 12(h)) any rights or remedies hereunder.  If
         any term, provision, covenant or restriction of this Agreement is
         held by a court of competent jurisdiction or Regulatory Authority
         to be invalid, void or unenforceable, the remainder of the terms,
         provisions, covenants and restrictions of this Agreement shall
         remain in full force and effect and shall in no way be affected,
         impaired or invalidated.  If for any reason such court or
         Regulatory Authority determines that the Option does not permit
         Holder to acquire, or does not require Issuer to repurchase, the
         full number of shares of Issuer Common Stock as provided in
         Section 2 (as may be adjusted herein), it is the express
         intention of Issuer to allow Holder to acquire or to require
         Issuer to repurchase such lesser number of shares as may be
         permissible without any amendment or modification hereof.

                        (d)  Governing Law.  This Agreement shall be
         governed and construed in accordance with the laws of the State
         of North Carolina without regard to any applicable conflicts of
         law rules.

                        (e)  Descriptive Headings.  The descriptive
         headings contained herein are for convenience of reference only
         and shall not affect in any way the meaning or interpretation of
         this Agreement.

                        (f)  Notices.  All notices and other
         communications hereunder shall be in writing and shall be deemed
         given if delivered personally, telecopied (with confirmation) or
         mailed by registered or certified mail (return receipt requested)
         to the parties at the addresses set forth in the Plan (or at such
         other address for a party as shall be specified by like notice).

                        (g)  Counterparts.  This Agreement and any
         amendments hereto may be executed in two counterparts, each of
         which shall be considered one and the same agreement and shall
         become effective when both counterparts have been signed, it
         being understood that both parties need not sign the same
         counterpart.

                        (h)  Assignment.  Neither this Agreement nor any
         of the rights, interests or obligations hereunder or under the
         Option shall be assigned by any of the parties hereto (whether by
         operation of law or otherwise) without the prior written consent
         of the other party, except that Holder may assign this Agreement
         to a wholly-owned subsidiary of Holder and Holder may assign its
         rights hereunder in whole or in part after the occurrence of a
         Purchase Event.  Subject to the preceding sentence, this 

                                        A-19





         Agreement shall be binding upon, inure to the benefit of and be
         enforceable by the parties and their respective successors and
         assigns.

                        (i)  Further Assurances.  In the event of any
         exercise of the Option by the Holder, Issuer and the Holder shall
         execute and deliver all other documents and instruments and take
         all other action that may be reasonably necessary in order to
         consummate the transactions provided for by such exercise.

                        (j)  Specific Performance.  The parties hereto
         agree that this Agreement may be enforced by either party through
         specific performance, injunctive relief and other equitable
         relief.  Both parties further agree to waive any requirement for
         the securing or posting of any bond in connection with the
         obtaining of any such equitable relief and that this provision is
         without prejudice to any other rights that the parties hereto may
         have for any failure to perform this Agreement. 
























                                        A-20





                   IN WITNESS WHEREOF, Issuer and Grantee have caused this
         Stock Option Agreement to be signed by their respective officers
         thereunto duly authorized, all as of the day and year first
         written above.
