a "Headlands Stock Option"), whether vested or unvested, shall be converted into
an option to acquire, on the same terms and conditions as were applicable under
such Headlands Stock Option, the number of shares of GreenPoint Common Stock
equal to (a) the number of shares of Headlands Common Stock subject to the
Headlands Stock Option, multiplied by (b) the Exchange Ratio (such product
rounded to the nearest whole number) (a "Replacement Option"), at an exercise
price per share (rounded to the nearest whole cent) equal to (y) the aggregate
exercise price for the shares of Headlands Common Stock which were purchasable
pursuant to such Headlands Stock Option divided by (z) the number of full shares
of GreenPoint Common Stock subject to such Replacement Option in accordance with
the foregoing.  At or prior to the Effective Time, GreenPoint shall take all
corporate action necessary to reserve for issuance a sufficient number of shares
of GreenPoint Common Stock for delivery upon exercise of the Headlands Stock
Options assumed by it in accordance with this Section 3.6.  As soon as
reasonably 

                                       13
<PAGE>
 
practicable after the Effective Time, GreenPoint shall file a registration
statement on Form S-3 or Form S-8, as the case may be (or any successor or
other appropriate forms), or another appropriate form (or shall cause such
Headlands Stock Options to be deemed to be an option issued pursuant to a
GreenPoint stock option or compensation plan for which a sufficient number of
shares of GreenPoint Common Stock have previously been registered pursuant to
an appropriate registration form) with respect to the shares of GreenPoint
Common Stock subject to such Headlands Stock Options, and shall use its
reasonable best efforts to maintain the effectiveness of such registration
statement(s) (and maintain the current status of the prospectus(es) contained
therein) for so long as such Headlands Stock Options remain outstanding.
Notwithstanding the foregoing, each Headlands Stock Option which is intended
to be an "incentive stock option" (as defined in Section 422 of the Code)
shall be adjusted in accordance with the requirements of Section 424 of the
Code. At or prior to the Effective Time, Headlands shall take all action, if
any, necessary with respect to the Headlands Stock Plans to permit the
replacement of the outstanding Headlands Stock Options by GreenPoint pursuant
to this Section 3.6. At the Effective Time, GreenPoint shall assume the 1997
Executive and Non-Employee Director Stock Option Plan; provided, that such
assumption shall be only in respect of the Replacement Options and that
GreenPoint shall have no obligation with respect to any awards under the
Headlands Stock Plans other than the Replacement Options and shall have no
obligation to make any additional grants or awards under such assumed
Headlands Stock Plans.

          (b)  With respect to the 1998 Employee Stock Purchase Plan, no new 
purchase periods will begin after December 31, 1998.

     commitment letter or similar submission to, or extraordinary supervisory
     letter from, any Regulatory Authority.

               (ii)  Neither Headlands nor any of its Subsidiaries has been
     advised by any Regulatory Authority that such Regulatory Authority is
     contemplating issuing or requesting (or is considering the
     appropriateness of issuing or requesting) any such order, decree,
     agreement, memorandum of understanding, commitment letter, supervisory
     letter or similar submission.

               (iii) Headlands has filed all reports required to be filed with
     HUD pursuant to the Home Mortgage Disclosure Act, and the information
     contained in such reports was true and correct in all material respects
     when filed.

          (i)  Compliance with Laws.  Each of Headlands and its Subsidiaries:
               --------------------                                          

               (i)   in the conduct of its business, is in compliance in all
     material respects with all applicable federal, state, local and foreign
     statutes, laws, regulations, ordinances, rules, judgments, orders or
     decrees applicable thereto or to the employees conducting such
     businesses, including, without limitation, the Truth in Lending Act and
     Regulation Z promulgated thereunder, the Equal Credit Opportunity Act of
     1974, as amended, and the regulations promulgated thereunder, the Real
     Estate Settlement Procedures Act, the Fair Debt Collection Practices Act
     and all other applicable fair lending laws and other laws relating to
     discriminatory business practices;

               (ii)  has all permits, licenses, authorizations, orders and
     approvals of, and has made all filings, applications and registrations
     with, all Governmental Authorities that are

                                       25
<PAGE>
 
     required in order to permit them to own or lease their properties and to
     conduct their businesses in all material respects as presently conducted;
     all such permits, licenses, certificates of authority, orders and approvals
     are in full force and effect and, to Headlands's knowledge, no suspension
     or cancellation of any of them is threatened; and

               (iii) has received, since December 31, 1996, no notification or
     communication from any Governmental Authority (A) asserting that
     Headlands or its Subsidiaries (or any other subsidiary then-existing) is
     not in compliance with any statute, regulation, or ordinance or (B)
     threatening to revoke any license, franchise, permit, or governmental
     authorization (nor, to Headlands's knowledge, do any grounds for any of
     the foregoing exist).

          (j)  Material Contracts; Defaults.  Except for those agreements and 
               ----------------------------                                   
other documents filed as exhibits to its SEC Documents, and except as
contemplated by this Plan, neither Headlands nor any of its Subsidiaries are a
party to, bound by or subject to any agreement, contract, arrangement,
commitment or understanding (whether written or oral) (i) that is a "material
contract" within the meaning of Item 601(b)(10) of the SEC's Regulation S-K
(without giving effect to the "ordinary course" exception set forth therein)
or (ii) that materially restricts the conduct of business by Headlands or its
Subsidiaries. Neither Headlands nor any of its Subsidiaries is in default
under any material contract, agreement, commitment, arrangement, lease,
insurance policy or other instrument to which it is a party, by which its
respective assets, business, or operations may be bound or affected, or under
which it or its respective assets, business, or operations receives benefits,
and there are no events or conditions arising as a result of actions or
omissions of Headlands or its Subsidiaries which, with the passing of time or
notice, or both, would constitute a default or breach thereunder, and with
respect to the counterparty or counterparties to each such contract,
agreement, commitment, arrangement, lease, insurance policy or other
instrument to the knowledge of Headlands's or any of its Subsidiaries there
exists or is threatened thereunder no default, breach or other event or
condition, which with the passage of time or notice, or both, would constitute
a default or breach thereunder. None of Headlands nor any of its Subsidiaries
is subject to, or bound by, any contract containing covenants which (i) limit
the ability of it to compete in any line of business or with any person, or
(ii) 

                                       26
<PAGE>
 
involve any restriction of geographical area in which, or method by
which, it may carry on its business (other than as may be required by law or
any applicable Regulatory Authority).

          (k)  No Brokers.  No action has been taken by Headlands that would 
               ----------                                                    
give rise to any valid claim against any party hereto for a brokerage
commission, finder's fee or other like payment with respect to the
transactions contemplated by this Plan, excluding a Previously Disclosed fee
to be paid to NationsBanc Montgomery Securities, LLC.

          (l)  Employee Benefit Plans.
               ---------------------- 

               (i)  Section 5.3(l)(i) of Headlands's Disclosure Schedule 
                    -----------------                                    
     contains a complete and accurate list of all existing material bonus,
     incentive, deferred compensation, pension, retirement, profit-sharing,
     thrift, savings, employee stock ownership, stock bonus, stock purchase,
     restricted stock, stock option, severance, welfare and fringe benefit
     plans, group insurance, employment, consulting or severance agreements
     and all similar practices, policies and arrangements maintained or
     contributed to by Headlands or its Subsidiaries in which any employee or
     former employee (the "Employees"), consultant or former consultant (the
     "Consultants") or director or former director (the "Directors") of
     Headlands or its Subsidiaries participates or to which any such
     Employees, Consultants or Directors are a party (the "Compensation and
     Benefit Plans"). Neither Headlands nor any of its Subsidiaries has any
     commitment to create any additional Compensation and Benefit Plan or to
     amend, modify or change any existing Compensation and Benefit Plan.
     Except as set forth in Section 5.3(e)(i) of Headlands's Disclosure
     Schedule, Headlands or its Subsidiaries has reserved the right to amend,
     modify, change or terminate any Compensation and Benefit Plan.

               (ii) Each Compensation and Benefit Plan has been operated and
     administered in all material respects in accordance with its terms and
     with ERISA and the Code, or any regulations or rules promulgated
     thereunder. Each Compensation and Benefit Plan which is an "employee
     pension benefit plan" within the meaning of Section 3(2) of ERISA (a
     "Pension Plan") and which is intended to be qualified under Section
     401(a) of the Code has received a favorable determination letter
     (including a determination that the related trust under such Compensation
     and Benefit Plan is exempt from tax under Section 501(a) of the Code) 

                                       27
<PAGE>
 
     from the IRS for "TRA" (as defined in Section 1 of Rev. Proc. 93-39), or
     will file for such determination letter prior to the expiration of the
     remedial amendment period for such Compensation and Benefit Plan, and
     Headlands is not aware of any circumstances likely to result in revocation
     of any such favorable determination letter. There is no pending or, to the
     knowledge of Headlands, threatened legal action, suit or claim relating to
     any Compensation and Benefit Plan, and to the knowledge of Headlands, no
     set of circumstances exists which may reasonably give rise to a claim or
     lawsuit, against any Compensation and Benefit Plan, any fiduciaries thereof
     with respect to their duties to any Compensation and Benefit Plan or the
     assets of any of the trusts under any Compensation and Benefit Plan which
     could reasonably be expected to result in a material liability of Headlands
     or its Subsidiaries to the PBGC, the Department of Treasury, the DOL, any
     Compensation and Benefit Plan or any current or former participant in any
     Compensation and Benefit Plan. Neither Headlands nor any of its
     Subsidiaries has engaged in a transaction, or omitted to take any action,
     with respect to any Compensation and Benefit Plan that would reasonably be
     expected to subject Headlands or its Subsidiaries to a tax or penalty
     imposed by either Section 4975 of the Code or Section 502 of ERISA,
     assuming for purposes of Section 4975 of the Code that the taxable period
     of any such transaction expired as of the date hereof.

               (iii) No Compensation and Benefit Plan is subject to Title IV
     or Section 302 of ERISA or Sections 412 or 4971 of the Code. No liability
     under Title IV or Section 302 of ERISA or Sections 412 or 4971 of the
     Code has been or is expected to be incurred by Headlands or its
     Subsidiaries with respect to any frozen or terminated "single-employer
     plan", within the meaning of Section 4001(a)(15) of ERISA, currently or
     formerly maintained by any of them, or any single-employer plan of any
     entity (an "ERISA Affiliate") which is considered one employer with
     Headlands or its Subsidiaries under Section 4001(a)(14) of ERISA or
     Section 414(b)(c)(m) or (o) of the Code (an "ERISA Affiliate Plan"). None
     of Headlands, any of its Subsidiaries or any ERISA Affiliate has
     contributed, or has been obligated to contribute, to a Multiemployer Plan
     within the meaning of Subtitle E of Title IV of ERISA or a plan that has
     two or more contributing sponsors at least two of whom are not under
     common control within the meaning of Section 4063 of ERISA, at any time
     since September 26, 1980. To the knowledge of Headlands, there is no
     pending investigation or enforcement action by the PBGC, the DOL or IRS

                                       28
<PAGE>
 
     or any other governmental agency with respect to any Compensation and
     Benefit Plan.

               (iv) All contributions required to be made under the terms of
     any Compensation and Benefit Plan have been timely made or have been
     reflected on Headlands's financial statements to the extent required by
     generally accepted accounting principles. None of Headlands, any of its
     Subsidiaries or any ERISA Affiliate (x) has provided, or would reasonably
     be expected to be required to provide, security to any Pension Plan or to
     any ERISA Affiliate Plan pursuant to Section 401(a)(29) of the Code, and
     (y) has taken any action, or omitted to take any action, that has
     resulted, or would reasonably be expected to result, in the imposition of
     a lien under Section 412(n) of the Code or pursuant to ERISA.

               (v)   Neither Headlands nor any of its Subsidiaries has any
     obligations to provide retiree health and life insurance or other retiree
     death benefits under any Compensation and Benefit Plan, other than
     benefits mandated by Section 4980B of the Code. Except as set forth in
     Schedule 5.3(l)(i) of Headlands's Disclosure Schedule, there has been no
     communication to Employees by Headlands or its Subsidiaries that would
     reasonably be expected to promise or guarantee such Employee retiree
     health or life insurance or other retiree death benefits on a permanent
     basis.

               (vi)  Headlands and its Subsidiaries do not maintain any
     Compensation and Benefit Plans covering current or former foreign
     employees of either.

               (vii) With respect to each Compensation and Benefit Plan, if
     applicable, Headlands has provided or made available to GreenPoint, true
     and complete copies of its most recent (A) Compensation and Benefit Plan
     documents and amendments thereto, (B) trust instruments and insurance
     contracts and amendments thereto, (C) Annual Report (Form 5500 Series)
     and accompanying schedules, if any, (D) summary plan description and any
     material modifications thereto, if any (in each case, whether or not
     required to be furnished under ERISA), and (E) actuarial report, if any.

               (viii) The consummation of the transactions contemplated by
     this Plan would not, directly or indirectly (including, without
     limitation, as a result of any termination of 

                                       29
<PAGE>
 
     employment prior to or following the Effective Time) reasonably be
     expected to (A) entitle any Employee, Consultant or Director to any
     payment (including severance pay or similar compensation) or any increase
     in compensation, (B) result in the vesting or acceleration of any
     benefits under any Compensation and Benefit Plan or (C) result in any
     material increase in benefits payable under any Compensation and Benefit
     Plan.

               (ix) Neither Headlands nor any of its Subsidiaries maintains
     any compensation plans, programs or arrangements the payments under which
     are not reasonably expected to be deductible as a result of the
     limitations under Section 162(m) of the Code and the regulations issued
     thereunder.

               (x)  As a result, directly or indirectly, of the transactions
     contemplated by this Plan (including, without limitation, as a result of
     any termination of employment prior to or following the Effective Time),
     none of GreenPoint, Headlands or the Surviving Corporation, or any of
     their respective Subsidiaries will be obligated to make a payment that
     would be characterized as an "excess parachute payment" to an individual
     who is a "disqualified individual" (as such terms are defined in Section
     280G of the Code), without regard to whether such payment is reasonable
     compensation for personal services performed or to be performed in the
     future.

          (m)  Labor Matters.  Neither Headlands nor any of its Subsidiaries 
               -------------                                                 
is a party to or is bound by any collective bargaining agreement, contract or
other agreement or understanding with a labor union or labor organization, nor
is Headlands or its Subsidiaries the subject of a proceeding asserting that
Headlands or its Subsidiaries has committed an unfair labor practice (within
the meaning of the National Labor Relations Act) or seeking to compel
Headlands or its Subsidiaries to bargain with any labor organization as to
wages or conditions of employment, nor is there any strike or other labor
dispute involving Headlands or its Subsidiaries pending or, to Headlands's
knowledge, threatened, nor is Headlands aware of any activity involving its or
its Subsidiaries's employees seeking to certify a collective bargaining unit
or engaging in other organizational activity.

          (n)  Takeover Laws; Dissenters Rights.  Headlands has taken all 
               --------------------------------                           
action required to be taken by it in order to exempt this Plan, the Stock
Option Agreement and the transactions contemplated hereby and thereby from,
and this Plan, the Stock Option Agreement and the transactions 

                                       30
<PAGE>
 
contemplated hereby and thereby are exempt from, the requirements of any
"moratorium", "control share", "fair price", "affiliate transaction",
"business combination" or other antitakeover laws and regulations of any state
(collectively, "Takeover Laws"), including, without limitation, the State of
California. Holders of Headlands Common Stock do not have dissenters' or
appraisal rights in connection with the execution of this Plan or the
consummation of any of the transactions contemplated hereby.

          (o)  Environmental Matters.  Neither the conduct nor operation of 
               ---------------------        
Headlands or its Subsidiaries (or any other subsidiary of Headlands existing
prior to the date hereof) nor any condition of any property presently or
previously owned, leased or operated by any of them (including, without
limitation, in a fiduciary or agency capacity), or on which any of them holds
a Lien, violates or violated Environmental Laws and no condition has existed
or event has occurred with respect to any of them or any such property that,
with notice or the passage of time, or both, is reasonably likely to result in
liability under Environmental Laws. Neither Headlands nor any of its
Subsidiaries (or any other subsidiary of Headlands existing prior to the date
hereof) has received any notice from any Governmental Authority, or to its
knowledge, any other person, that Headlands or its Subsidiaries (or any other
subsidiary of Headlands existing prior to the date hereof) or the operation or
condition of any property ever owned, leased, operated, or held as collateral
or in a fiduciary capacity by any of them are or were in violation of or
otherwise are alleged to have liability under any Environmental Law,
including, but not limited to, responsibility (or potential responsibility)
for the cleanup or other remediation of any pollutants, contaminants, or
hazardous or toxic wastes, substances or materials at, on, beneath, or
originating from any such property.

          (p)  Tax Matters.
               ----------- 

               (i)  (A) All Tax Returns that are required to be filed (taking
     into account any extensions of time within which to file) by or with
     respect to Headlands and its Subsidiaries (and any other subsidiary of
     Headlands existing prior to the date hereof) have been duly filed and
     such filed Tax Returns are true, correct and complete in all material
     respects, (B) all Taxes shown to be due on the Tax Returns referred to in
     clause (A) have

                                       31
<PAGE>
 
     been paid in full, (C) the federal and state income Tax Returns referred
     to in clause (A) have been examined by the IRS or the appropriate state
     taxing authority or the period for assessment of the Taxes in respect of
     which such Tax Returns were required to be filed has expired, (D) all
     deficiencies asserted or assessments made as a result of such
     examinations have been paid in full or are being contested in good faith
     by appropriate proceedings and have been reserved against in accordance
     with GAAP, (E) no issues that have been raised by the relevant taxing
     authority in connection with the examination of any of the Tax Returns
     referred to in clause (A) are currently pending, and (F) no waivers of
     statutes of limitation have been given by or requested with respect to
     any Taxes of Headlands or its Subsidiaries. Headlands has made available
     to GreenPoint true and correct copies of the United States federal income
     Tax Returns filed by Headlands and its Subsidiaries for each of the three
     most recent fiscal years ended on or before December 31, 1997. Neither
     Headlands nor any of its Subsidiaries has any liability with respect to
     Taxes that accrued on or before the end of the most recent period covered
     by Headlands's SEC Documents filed prior to the date hereof in excess of
     the amounts accrued with respect thereto that are reflected in the
     financial statements included in Headlands's SEC Documents filed on or
     prior to the date hereof except for the liability under the Tax
     Agreement. As of the date hereof, neither Headlands nor any of its
     Subsidiaries (or any other subsidiary of Headlands existing prior to the
     date hereof) has any reason to believe that any conditions exist that
     might prevent or impede the Merger from qualifying as a reorganization
     within the meaning of Section 368(a) of the Code.

               (ii)  No Tax is required to be withheld pursuant to Section
     1445 of the Code as a result of the transfer contemplated by this Plan.

               (iii) Headlands is not a party to any tax sharing, allocation or
     indemnification agreement, other than the Tax Indemnification Agreement
     dated as of October 15, 1997 by and between the Company and Headlands's
     shareholders prior to termination of S corporation status (the "Tax
     Agreement"). No amounts are currently due and payable by Headlands under
     the Tax Agreement and, to the best knowledge of Headlands, no adjustments
     have been asserted or proposed by any taxing authority that could
     reasonably be expected to result in an obligation of Headlands to pay any
     amounts under the Tax Agreement.

                                       32
<PAGE>
 
               (iv) Headlands (and any predecessor thereof) made a valid
     election to be an S corporation for federal income tax purposes effective
     for the first taxable year during its corporate existence and such
     election remained in effect for each subsequent taxable year until
     January 31, 1998, and, where required to obtain similar treatment for
     state and local tax purposes, Headlands (and any predecessor thereof)
     made valid elections or took other action to obtain such treatment. With
     the consent of the shareholders whose consent is required by Section
     1362(d)(1) of the Code and Treas. Reg. (S) 1.1362-2(a), Headlands revoked
     its S corporation election in the manner prescribed in Treas. Reg. (S)
     1.1362-6 and such revocation was effective on January 31, 1998. With the
     consent of the shareholders whose consent is required by Section
     1362(e)(3) of the Code and Treas. Reg. (S) 1.1362-3(b)(1), Headlands
     elected in the manner prescribed by Treas. Reg. (S) 1.1362-6 to allocate
     its income for the "S termination year" (as defined in Section 1362(e)(4)
     of the Code) between the "S short year" described in Section
     1362(e)(1)(A) of the Code and the "C short year" described in Section
     1362(e)(1)(B) of the Code on the basis of the Company's normal tax
     accounting method.

               (v)  Headlands has not agreed to and is not required to make
     any adjustment under Section 481(a) of the Code by reason of a change in
     method of accounting or otherwise.


          (q)  Risk Management Instruments.  All interest rate swaps, caps, 
               ---------------------------                                  
floors, option agreements, futures and forward contracts and other similar
risk management arrangements, whether entered into for Headlands's own
account, or for the account of its Subsidiaries or their customers (all of
such material arrangements are listed on Section 5.3(q) of Headlands's
Disclosure Schedule), were entered into (i) in accordance with prudent
business practices and all applicable laws, rules, regulations and regulatory
policies and (ii) with counterparties believed to be financially responsible
at the time; and each of them constitutes the valid and legally binding
obligation of Headlands or any of its Subsidiaries, enforceable in accordance
with its terms (except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and
similar laws of general applicability relating to or affecting creditors'
rights or by general equity principles), and are in full force and effect.
Neither Headlands nor any of its Subsidiaries, nor to Headlands's knowledge,
any 

                                       33
<PAGE>
 
other party thereto, is in breach of any of its obligations under any such
agreement or arrangement.

          (r)  Books and Records.  The books and records of Headlands and its 
               -----------------                                              
Subsidiaries have been properly and accurately maintained, and there are no
material inaccuracies or discrepancies of any kind contained or reflected
therein, and they fairly present the financial position of Headlands and its
Subsidiaries.

          (s)  Insurance.  Section 5.3(s) of Headlands's Disclosure Schedule 
               ---------                                                     
sets forth all of the insurance policies, binders, or bonds maintained by
Headlands or its Subsidiaries ("Insurance Policies"). Headlands and its
Subsidiaries are insured with reputable insurers against such risks and in
such amounts as the management of Headlands reasonably has determined to be
prudent in accordance with industry practices. All the Insurance Policies are
in full force and effect; Headlands and its Subsidiaries are not in default
thereunder; and all claims thereunder have been filed in due and timely
fashion.

          (t)  Accounting Treatment.  As of the date hereof, Headlands is 
               --------------------                                       
aware of no reason why the Merger will fail, or could reasonably be expected
to fail, to qualify for "pooling of interests" accounting treatment.


          (u)  Mortgage Banking Business.  (i)  Licenses and Qualifications.  
               -------------------------        ---------------------------   
Headlands (the only Headlands entity that services or originates loans) (A) is
an approved (1) HUD mortgagee and servicer for FHA-insured loans, (2) lender
and servicer for VA-insured loans, (3) seller/servicer of one-to-four-family
first and second mortgages for FNMA and FHLMC, and (4) GNMA issuer and
servicer of GNMA-guaranteed mortgage-backed securities, (B) has all other
certifications, authorizations, licenses, permits and other approvals
necessary to conduct its current business, (C) is in good standing under all
applicable federal, state and local laws and regulations thereunder as a
lender and servicer and (D) is in good standing with all authorities and
servicers for the state bond programs in which it participates. As of the date
hereof, there is no pending or, to Headlands's knowledge, threatened
cancellation or reduction of any loan purchase commitment or other loan sale
contract to which Headlands is a party, and the obligations of Headlands under
each such contract are being performed by Headlands in accordance with its
terms. Headlands has no reason to believe that the 

                                       34
<PAGE>
 
underwriting waivers from FNMA and FHLMC, under current agreements with
Headlands, will be restricted or rescinded, or that the guarantee fees payable
to FNMA and FHLMC will be increased as a result of Headlands's credit
performance, or that Headlands will suffer a forced reduction of the master
commitment amount relating to FNMA or FHLMC purchases or swaps of loans, nor has
any such restriction, rescission, increase or reduction occurred at any time
since January 1, 1997.
 
        (ii) Title to Loans.  All loans held for Headlands's account, whether or
             --------------                                                    
not for future sale or delivery to an investor (the "Warehouse Loans"), are
owned by Headlands free and clear of any Lien, other than Liens in favor of
Headlands's lender banks pursuant to warehouse lines of credit and forward sale
commitments or similar agreements to sell any such loans to investors in the
ordinary course, and all Warehouse Loans meet all requirements for sale to the
intended investors. Each mortgage or deed of trust securing a Warehouse Loan has
been duly recorded or submitted for recordation in due course in the appropriate
filing office in the name of Headlands as mortgagee. Headlands has not released
any security for any Warehouse Loan, except upon receipt of reasonable
consideration for such release (as documented in the applicable Loan file), or
accepted prepayment of any such Warehouse Loan which has not been promptly
applied to such Warehouse Loan.

        (iii)  Compliance.  Each Warehouse Loan and each loan which is being 
               ----------
serviced by Headlands for the account of others (the "Serviced Loans", and
together with the Warehouse Loans, the "Loans") was underwritten and originated,
and the loan documents and loan files maintained by Headlands with respect
thereto are being maintained by Headlands in compliance with all applicable laws
and regulations and, if applicable, the requirements of the "Investor" (which
term means (x) FHLMC, FNMA, GNMA, or any other person, as the case may be, that
owns any of the Loans or any portion of a Pool of loans or holds beneficial
title to the Loans or any portion of a Pool of loans, but shall not mean the
holder of mortgage-backed securities or mortgage pass-through securities except
to the extent that the consent of such holder may be required in order for
Headlands to continue to have servicing rights with respect to the Loans related
thereto and (y) any person who owns servicing rights for loans serviced or
master serviced by Headlands pursuant to a Loan Servicing Agreement) acquiring
such Loan (or, if there is no such Investor, in accordance with Headlands's
underwriting standards then in 

                                       35
<PAGE>
 
effect) and the requirements of each person who insures or guarantees all or any
portion of the risk of loss upon borrower default on any of the Loans,
including, without limitation, the FHA, the VA and any private mortgage insurer,
and providers of life, hazard, flood, disability, title or other insurance with
respect to any of the Loans or the collateral therefor (each, an "Insurer"), if
any, in effect and applicable at the time such insurance was obtained. Headlands
has not done or failed to do, or caused to be done or omitted to be done, any
act, the effect of which would operate to invalidate or materially impair (i)
any approvals of any Agency or the FHA to insure, (ii) any VA guarantee or
commitment of the VA to guarantee, (iii) any private mortgage insurance or
commitment of any private mortgage insurer to insure, (iv) any title insurance
policy, (v) any hazard insurance policy, (vi) any flood insurance policy, (vii)
any fidelity bond, direct surety bond, errors and omissions or other insurance
policy required by any Agency, Investor or Insurer, (viii) any surety or
guaranty agreement, (ix) any guaranty issued by GNMA, FNMA or FHLMC to Headlands
respecting mortgage backed securities issued by Headlands and other like
guarantees or (x) the rights of Headlands under any Loan Servicing Agreement or
loan purchase commitment. No Agency, Investor or Insurer has (i) notified
Headlands, or to the knowledge of Headlands claimed, that Headlands has violated
or has not complied on a recurring basis with the applicable underwriting
standards with respect to Loans sold by Headlands to an Investor or (ii) imposed
restrictions on the activities (including commitment authority) of Headlands.

        (iv) Loan Files.  The loan documents relating to a Loan maintained in 
             ----------
the loan files of Headlands were in compliance with all applicable laws and
regulations at the time of the origination, assumption or modification of such
Loan, as the case may be. The loan files maintained by Headlands contain
originals (or, where necessitated by the terms of the applicable mortgage
servicing agreements, contain true, correct and complete copies) of the
documents relating to each Loan and the information contained in such loan files
with respect to each such Loan is true, complete and accurate and in compliance
with all applicable laws and regulations. Except as set forth in the loan
documents relating to a Loan maintained in the loan files of Headlands, the
terms of the note, bond, deed of trust and mortgage for each such Loan have not
been impaired, waived, altered or modified in any respect from the date of their
origination except by a written instrument which written instrument has been
recorded, or 

                                       36
<PAGE>
 
submitted for recordation in due course, if recordation is necessary to protect
the interests of the owner thereof. The substance of any such waiver, alteration
or modification has been communicated to and approved by (A) the relevant
Investor and Insurer (if any), to the extent required by the relevant Investor
and Insurer requirements, and (B) the title Insurer, to the extent required by
the relevant policies, and the terms of any such waiver, alteration or
modification are reflected in the loan documents. Except as set forth in the
loan documents maintained in the loan files by Headlands, no mortgagor has been
released from such mortgagor's obligations with respect to the applicable Loan.

        (v)  Loan Servicing Agreements.  All of the contracts pursuant to which
             -------------------------                                         
Headlands has the right and/or obligation to service loans (each, a "Loan
Servicing Agreement") are (A) valid and binding obligations of Headlands, and to
the knowledge of Headlands, of all the other parties thereto, (B) in full force
and effect, (C) enforceable in accordance with their terms (except where
enforcement thereof may be limited by bankruptcy, insolvency or other similar
laws affecting the enforcement of creditors' rights generally and by general
equity principles) and (D) owned by Headlands free and clear of any Lien, except
pursuant to the loan and security agreements Previously Disclosed. There is no
default by Headlands or claim of default against Headlands by any party under
any such Loan Servicing Agreement, and, except for the consummation of the
transactions contemplated by this Plan, no event has occurred which with the
passage of time or the giving of notice or both would constitute a default by
any party under any such Loan Servicing Agreement or would result in any such
mortgage servicing agreement being terminable by any party thereto. There is no
pending or, to the knowledge of Headlands, threatened cancellation of any Loan
Servicing Agreement and the obligations of Headlands under each Loan Servicing
Agreement are being performed by Headlands in accordance with the terms of such
Agreement and applicable rules or regulations. Headlands is not a subservicer
with respect to any of the Serviced Loans.

        (vi) No Recourse.  None of Headlands's servicing rights is subject to 
             -----------
recourse against the servicer, and Headlands is not subject to recourse in
connection with any Loans sold by it, in each case for losses on liquidation of
a loan, borrower defaults or repurchase obligations upon the occurrence of non-
payment or other events, other than events entitling Investors to 

                                       37
<PAGE>
 
request a repurchase of a loan because of alleged breaches of customary
representations and warranties relating to the origination or servicing thereof.

        (vii)  Escrow Account.  Unless otherwise prohibited by law or an 
               --------------
executed escrow waiver, Headlands collects all escrows related to the Loans, and
all escrow accounts have been maintained by Headlands and, to Headlands's
knowledge, all prior servicers in accordance with the related loan documents,
all applicable laws, rules, regulations, and requirements of Investors, Insurers
and governmental authorities, and in accordance with the applicable Loan
Servicing Agreements. Headlands has credited to the account of borrowers all
interest required to be paid on any escrow account in accordance with applicable
law and the terms of such agreements and loan documents. All escrow, custodial,
and suspense accounts related to the Loans are held in Headlands's name or the
investor's name by Headlands.

        (viii)  Advances.  There are no servicing or other contracts to which 
                --------                                                       
Headlands is a party which obligates it to make servicing advances for principal
and interest payments with respect to defaulted or delinquent Loans other than
in a manner as provided in standard and customary agreements with FNMA, FHLMC or
GNMA. To the extent made, any such advances are valid and subsisting amounts
owing to Headlands, subject to the terms of the applicable Loan Servicing
Agreement.

        (ix) Single Family Loans.  All of the Loans are secured by single 
             -------------------
family (i.e., one to four family) residential real property or, to the extent
that a Loan is secured by property other than a single family residential
property, such Loan is not a Warehouse Loan and has not been sold to any person
where Headlands has any recourse obligation.

        (x)  ARM Adjustments.  With respect to each Loan for which the interest 
             ---------------   
rate is not fixed for the entire term of the loan, Headlands has, since the date
it commenced servicing such loan and, to Headlands's knowledge, all prior
servicers have (A) properly and accurately entered into its system all data
required to service the loan in accordance with the related loan documents and
all regulations, (B) properly and accurately adjusted the monthly payment on
each payment adjustment date, (C) properly and accurately calculated the
amortization of principal and interest on each payment adjustment date, in each
case in 

                                       38
<PAGE>
 
compliance with all applicable laws, rules and regulations and the related loan
documents, and (D) executed and delivered any and all necessary notices required
under, and in a form that complies with, all applicable laws, rules and
regulations and the terms of the related loan documents regarding the interest
rate and payment adjustments.

        (xi) Pools.  Each Loan included in a pool of Loans originated, acquired 
             -----             
or serviced by Headlands (a "Pool") meets all eligibility requirements
(including, without limitation, all applicable requirements for obtaining
mortgage insurance certificates and loan guaranty certificates) for inclusion in
such Pool. All of such Pools have been finally certified or, if required,
recertified in accordance with all applicable laws, rules and regulations,
except where the time for certification or recertification has not expired. To
the knowledge of Headlands, no Pools have been improperly certified. The loan
file for each Loan included in a certified Pool contains all documents and
instruments necessary for the final certification or recertification of such
Pool. No Loan has been bought out of a Pool without all required prior written
approvals of the applicable Investors. Neither the execution, delivery or
performance of this Plan by Headlands nor the consummation by Headlands of the
transactions contemplated hereby will require any Pool to be recertified. The
aggregate unpaid principal balance outstanding of the Loans in each Pool equals
or exceeds the amount owing to the applicable Investors.

        (xii)  Securitization Transactions.
               --------------------------- 

                (A)  Headlands and its Subsidiaries, as servicer under the
applicable Loan Servicing Agreement (the "Securitization Servicer") of each
outstanding transaction under which Headlands or its Subsidiaries have sold or
pledged Loans in a securitization, whether sold under the Securities Act or
otherwise (a "Securitization Transaction"), has complied in all material
respects with all contracts, including the Loan Servicing Agreements, and all
conditions to be performed or satisfied by them with respect to all agreements
and arrangements pursuant to which such person is bound under such
Securitization Transaction (collectively, "Securitization Instruments").

                (B)  No Securitization Servicer or, to Headlands's knowledge, no
trustee or issuer with respect to any Securitization, has taken any action which
would reasonably be 

                                       39
<PAGE>
 
expected to adversely affect the characterization or tax treatment for federal,
state or local income or franchise tax purposes of the issuer or any securities
issued in a Securitization Transaction, and all required federal, state and
local tax and information returns relating to any Securitization Transaction
have been properly filed.

                (C)  Each representation and warranty made by Headlands or its
Subsidiaries in each "Purchase Agreement," "Pooling and Servicing Agreement,"
"Placement Agency Agreement," "Servicer's Indemnification Agreement" and any
other Securitization Instrument to which any of them was a party in any
Securitization Transaction was true and correct in all material respects
whenever made or reaffirmed by any of them and Headlands and its Subsidiaries
have each fully performed and carried out each covenant and agreement made by
any of them in any such Securitization Instrument.

                (D)  No rating agency has downgraded, or given Headlands or its
Subsidiaries any indication that it is considering a downgrading of any
securities issued in any Securitization Transaction, or of its rating of any
Securitization Servicer.

        (xiii)  Mortgage Insurance.  Each Loan which is indicated in the 
                ------------------
related loan documents to have FHA insurance is insured under the National
Housing Act or qualifies for such insurance. Each Loan which is indicated in the
related loan documents to be guaranteed by the VA is guaranteed under the
provisions of Chapter 37 of Title 38 of the United States Code to the extent
required by the applicable Investor or qualifies for such guarantee. As to each
FHA insurance certificate, each VA guarantee certificate, and each Loan which is
indicated in the related loan file to be insured by private mortgage insurance,
Headlands has complied with applicable provisions of the insurance or guarantee
contract and applicable laws and regulations, the insurance or guarantee is in
full force and effect with respect to each such Loan, and to the knowledge of
Headlands, there does not exist any event or condition which, but for the
passage of time or the giving of notice or both, can result in a revocation of
any such insurance or guarantee or constitute adequate grounds for the
applicable Insurer to refuse to provide insurance or guarantee payments
thereunder.

                                       40
<PAGE>
 
        (xiv)  Taxes and Insurance. Each Loan has been covered by a policy of
               -------------------    
hazard insurance and flood insurance, to the extent required by the Loan
Servicing Agreements relating thereto or any laws, rules, regulations or
Investor or Insurer requirements applicable to such Loan, all in a form usual
and customary in the industry and each of which is in full force and effect and
all amounts due and payable under each policy have been paid prior to the date
such payments were due; and all taxes, assessments, ground rents or other
applicable charges or fees due and payable as to each Loan have been paid prior
to the date such payments was due. Any and all claims under such insurance
policies have been submitted and processed in accordance with the applicable
Investor's and Insurer's requirements. Such insurance policies name Headlands
and its successors and assigns as mortgagee.

        (xv) Title Insurance. To the extent required by the applicable Investor,
             ---------------    
each Loan is covered by an ALTA lender's title insurance policy or other
generally acceptable form of policy of insurance or opinion of title acceptable
to the relevant Investor, and each such title insurance policy is issued by an
Insurer acceptable to the applicable Investor and qualified to do business in
the jurisdiction where the collateral securing such Loan is located, and insures
the originator and its successors and assigns as to the first priority lien of
the mortgage in the original principal amount of the Loan (or, in the case of a
second mortgage, the second priority lien). The applicable Investor, as assignee
of the originator's rights, is an insured of such lender's title insurance
policy, and such lender's policy is in full force and effect. Headlands has not,
nor, to Headlands's knowledge, has any prior servicer, performed any act or
omission which would impair the coverage of such lender's policy.

        (xvi)  Condemnation. Neither Headlands nor any of its Subsidiaries has
               ------------     
received notice of or has knowledge of any proceeding pending or threatened for
the partial or total condemnation of any of the collateral securing any of the
Loans, and neither Headlands nor any of its Subsidiaries has received notice or
has knowledge that all or any part of such collateral has been or will be
condemned.

        (xvii)  Tape. Headlands has previously delivered to GreenPoint a tape
                ----      
(magnetic media) on which certain information regarding the servicing portfolio
of Headlands as of September 

                                       41
<PAGE>
 
30, 1998 is recorded. Such tape accurately contains the list of serviced loans
as of such date. The loan characteristics recorded on such tape have been
Previously Disclosed, and the information contained on such tape is accurate.

        (v)  Disclosure. The representations and warranties contained in this
             ----------
Section 5.3 do not contain any untrue statement of a material fact.
- ------- ---

        (w)  Material Adverse Change. Since December 31, 1997, no event has
             -----------------------       
occurred or circumstances arisen that, individually or taken together with all
other events and circumstances, has had or is reasonably likely to have a
Material Adverse Effect on Headlands.

        (x)  Year 2000 Compliance. Headlands has adopted and implemented a
             --------------------  
commercially reasonable plan (a complete and correct copy of which has been
provided to GreenPoint) to provide (x) that the change of the year from 1999 to
the year 2000 will not materially and adversely affect the information and
business systems of Headlands or its Subsidiaries and (y) that the impacts of
such change on the vendors and customers of Headlands and its Subsidiaries will
not have a Material Adverse Effect on Headlands or its Subsidiaries. In
Headlands' reasonable best estimate, no expenditures materially in excess of
currently budgeted items will be required in order to cause the information and
business systems of Headlands and its Subsidiaries to operate properly following
the change of the year 1999 to the year 2000. Headlands reasonably expects that
it will resolve any issues related to such change of the year in accordance with
the timetable set forth in such plan (and in any event on a timely basis in
order to be resolved before the year 2000). Between the date of this Agreement
and the Effective Time, Headlands shall continue to use commercially reasonable
efforts to implement such plans.

        (y)  Transactions With Related Parties. There have been no transactions
             ---------------------------------                                  
involving amounts in excess of $250,000 individually and $750,000 in the
aggregate during the two years prior to the Effective Date between Headlands or
its Subsidiaries, on the one hand, and any affiliate of Headlands or its
Subsidiaries or any director, officer or employee of Headlands or its
Subsidiaries or any affiliate of any such person, on the other hand. All such
transactions involving related parties have been entered into on 

                                       42
<PAGE>
 
an arms-length basis and on commercially reasonable terms and conditions.

has been advised by any Regulatory Authority that such Regulatory Authority is
contemplating issuing or requesting (or is considering the appropriateness of
issuing or requesting) any such order, decree, agreement, memorandum of
understanding, commitment letter, supervisory letter or similar submission.

        (i)  Compliance with Laws.  GreenPoint and each of its Subsidiaries:
             --------------------                        

                (i)  in the conduct of its business, is in compliance with all

communication from any Governmental Authority (A) asserting that any of them is

        (j)  No Brokers. No action has been taken by GreenPoint that would give
             ----------    
rise to any valid claim against any party hereto for a brokerage commission,
finder's fee or other like payment with respect to the transactions contemplated
by this Plan, excluding a fee to be paid to Keefe, Bruyette & Woods Inc .

        (k)  Tax Treatment. As of the date hereof, neither GreenPoint nor any of
             -------------        
its Subsidiaries has any reason to believe that any conditions exist that might
prevent or impede the Merger from qualifying as a reorganization within the
meaning of Section 368(a) of the Code.

        (l)  Accounting Treatment. As of the date hereof, GreenPoint is aware of
             --------------------    
no reason why the Merger will fail, or could reasonably be expected to fail, to
qualify for "pooling of interests" accounting treatment.

        (m)  Disclosure. The representations and warranties contained in this
             ----------
Section 5.4 do not contain any untrue statement of a material fact.

other events and circumstances, has had or is reasonably likely to have a
Material Adverse Effect on GreenPoint or any of its Subsidiaries, taken as a
whole.

        (o)  Year 2000 Compliance. None of GreenPoint or any of its Significant
             --------------------                                               
Subsidiaries has received, or reasonably expects to receive, a "Year 2000
Deficiency Notification Letter" (as such term is employed in the Federal
Reserve's Supervision and Regulation Letter No. SR 98-3(SUP), dated March 4,
1998). GreenPoint has disclosed to Headlands a complete and correct copy of
GreenPoint's plan for addressing the issues set forth in the statements of the
Federal Financial Institutions Examination Council, dated May 5, 1997, entitled
"Year 2000 Project Management Awareness," and December 1997, entitled "Safety
and Soundness Guidelines Concerning the Year 2000 Business Risk," as such issues
affect GreenPoint and its Significant Subsidiaries, and such plan will provide
so that (x) the change of the year form 1999 to the year 2000 will not
materially and adversely affect the information and business systems of
GreenPoint or any of its Significant Subsidiaries and (y) that the impacts of
such change on the vendors and customers of GreenPoint and its Significant
Subsidiaries will not have a Material Adverse Effect 

                                       48

its Significant Subsidiaries has received, and has no reason to believe that it
will receive, regulatory criticism of such plan that could jeopardize such
plan's approval.

                                   COVENANTS

        6.1  Reasonable Best Efforts.  Subject to the terms and conditions of
             -----------------------                                         
this Plan, each of Headlands and GreenPoint agrees to use its reasonable best

consider and vote upon the approval and adoption of this Plan and any other
matters required to be approved by Headlands's stockholders for consummation of
the Merger (including any adjournment or postponement, the "Headlands Meeting"),
as promptly as practicable after the Registration Statement is declared
effective.  The Headlands Board shall recommend such approval, and Headlands
shall (subject to compliance with its fiduciary duties under the law as
reasonably determined in good faith) take all reasonable, lawful action to
solicit such approval by its stockholders.

        6.3  Registration Statement.
             ---------------------- 

        (a)  As soon as reasonably practicable after the date hereof, GreenPoint
agrees to prepare a registration statement on Form S-4 or other applicable form
(the "Registration Statement") to be filed by GreenPoint with the SEC in
connection with the issuance of GreenPoint Common Stock in the Merger (including
the proxy statement and prospectus and other proxy solicitation materials of

<PAGE>
 
agrees to cooperate, and to cause its Subsidiaries to cooperate, with
GreenPoint, its counsel and its accountants, in GreenPoint's preparation of the
Registration Statement and the Proxy Statement; and provided that Headlands and
its Subsidiaries have cooperated as required above, GreenPoint agrees to file
the Proxy Statement in preliminary form with the SEC as promptly as reasonably
practicable, and to file the Registration Statement with the SEC as soon as
reasonably practicable after any SEC comments with respect to the preliminary
Proxy Statement are resolved. Each of Headlands and GreenPoint agrees to use all
reasonable efforts to cause the Registration Statement to be declared effective
under the Securities Act as promptly as reasonably practicable after filing
thereof. GreenPoint also agrees to use all reasonable efforts to obtain all
necessary state securities law or "Blue Sky" permits and approvals required to

furnish to GreenPoint all information concerning Headlands, its Subsidiaries,
officers, directors and stockholders required to be included in the Registration
Statement or Proxy Statement under the Securities Act as may be reasonably
requested by GreenPoint in connection with the foregoing.

        (b)  Each of Headlands and GreenPoint agrees, as to itself and its
Subsidiaries, that none of the information supplied or to be supplied by it for
inclusion or incorporation by reference in (i) the Registration Statement will,
at the time the Registration Statement and each amendment or supplement thereto,
if any, becomes effective under the Securities Act, contain any untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein not misleading, (ii) the
Proxy Statement and any amendment or supplement thereto will, at the date of
mailing to stockholders and at the time of the Headlands Meeting, contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein not misleading
or any statement which, in the light of the circumstances under which such
statement is made, is false or misleading with respect to any material fact, or
omits to state any material fact necessary in order to make the statements
therein not false or misleading or necessary to correct any statement in any
earlier statement in the Proxy Statement or any amendment or supplement thereto,
and (iii) any other documents (and any supplements or amendments to such
documents) to be filed with any Regulatory Authority in 

                                       50

such Regulatory Authority, contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein not misleading. Each of Headlands and GreenPoint
further agrees that if it shall become aware prior to the Effective Date of any
information furnished by it that would cause any of the statements in the Proxy
Statement to be false or misleading with respect to any material fact, or to
omit to state any material fact necessary to make the statements therein not
false or misleading, to promptly inform the other party and to take the
necessary steps to correct the Proxy Statement.

        (c)  GreenPoint agrees to advise Headlands, promptly after GreenPoint
receives notice thereof, of the time when the Registration Statement has become
effective or any supplement or amendment has been filed, of the issuance of any
stop order or the suspension of the qualification of GreenPoint Common Stock for
offering or sale in any jurisdiction, of the initiation or threat of any
proceeding for any such purpose, or of any request by the SEC for the amendment
or supplement of the Registration Statement or for additional information.

              --------------                                                  
will not, without the prior approval of the other party, issue any press release
or written statement for general circulation relating to the transactions
contemplated hereby, except as otherwise required by applicable law or
regulation or NYSE or NASDAQ rules.

        6.5.  Access; Information.

and subject to applicable laws relating to the exchange of information, it shall
afford the other party and the other party's officers, employees, counsel,
accountants and other authorized representatives, such access during normal
business hours throughout the period prior to the Effective Time to the books,
records (including, without limitation, tax returns and work papers of
independent auditors), properties, personnel and to such other information as
any party may reasonably request and, during such period, it shall furnish
promptly to such other party (i) a copy of each material report, schedule and
other document filed by it pursuant to the requirements of federal or state
securities or banking laws, and (ii) all other information 

                                       51
<PAGE>
 
concerning the business, properties and personnel of it as the other may
reasonably request.

        (b)  Each agrees that it will not, and will cause its representatives
not to, use any information obtained pursuant to this Section 6.5 (as well as
                                                      -----------
any other information obtained prior to the date hereof in connection with the
entering into of this Plan) for any purpose unrelated to the consummation of the
transactions contemplated by this Plan. Subject to the requirements of law, each
party will keep confidential, and will cause its representatives to keep
confidential, all information and documents obtained pursuant to this Section
                                                                      -------
6.5 (as well as any other information obtained prior to the date hereof in
- ---
connection with the entering into of this Plan) unless such information (i) was
already known to such party, (ii) becomes available to such party from other
sources not known by such party to be bound by a confidentiality obligation,
(iii) is disclosed with the prior written approval of the party to which such
information pertains or (iv) is or becomes readily ascertainable from published
information or trade sources. In the event that this Plan is terminated or the
transactions contemplated by this Plan shall otherwise fail to be consummated,
each party shall promptly cause all copies of documents or extracts thereof
containing information and data as to another party hereto to be returned to the
party which furnished the same.

        (c)  No investigation by either party of the business and affairs of the
other shall affect or be deemed to modify or waive any representation, warranty,
covenant or agreement in this Plan, or the conditions to either party's
obligation to consummate the transactions contemplated by this Plan.

        6.6.  Acquisition Proposals.  Headlands agrees that it shall not, and
              ---------------------                                          
shall cause its Subsidiaries and its Subsidiaries's officers, directors, agents,
advisors and affiliates not to, solicit or encourage inquiries or proposals with
respect to, or engage in any negotiations concerning, or provide any
confidential information to, or have any discussions with, any person relating
to, any Acquisition Proposal; provided, however, that Headlands may, and may
                              --------  -------                             
authorize and permit its officers, directors, employees or agents to, furnish or
cause to be furnished confidential information and may participate in such
discussions and negotiations if Headlands's Board of Directors, after having
consulted with and considered the advice of outside 

                                       52
<PAGE>
 
counsel has determined that the failure to provide such information or
participate in such negotiations and discussions would cause the members of such
Board of Directors to breach their fiduciary duties under applicable laws.
Headlands agrees that it shall immediately cease and cause to be terminated any
activities, discussions or negotiations conducted prior to the date of this Plan
with any parties other than GreenPoint with respect to any of the foregoing and
shall use its reasonable best efforts to enforce any confidentiality or similar
agreement relating to an Acquisition Proposal. Headlands shall promptly (within
24 hours) advise GreenPoint following the receipt by Headlands of any
Acquisition Proposal and the substance thereof (including the identity of the
person making such Acquisition Proposal), and advise GreenPoint of any
developments with respect to such Acquisition Proposal immediately upon the
occurrence thereof.

        6.7.  Affiliate Agreements.
              -------------------- 

        (a)  Not later than the 15th day prior to the mailing of the Proxy
Statement, (i) Headlands shall deliver to GreenPoint a schedule of each person
that, to the best of its knowledge, is or is reasonably likely to be, as of the
date of the Headlands Meeting, deemed to be an "affiliate" of Headlands (each, a
"Headlands Affiliate") as that term is used in Rule 145 under the Securities Act
or SEC Accounting Series Releases 130 and 135.

        (b)  Each of Headlands and GreenPoint shall use its reasonable best
efforts to cause each person who may be deemed to be a Headlands Affiliate to
execute and deliver to GreenPoint on or before the date of mailing of the Proxy
Statement an agreement in the form attached hereto as Exhibit C. Such Headlands
Affiliates will not receive New Certificates until such agreement is delivered 
to GreenPoint.

        6.8.  Takeover Laws.  No party hereto shall take any action that would
              -------------                                                   
cause the transactions contemplated by this Plan or the Stock Option Agreement
to be subject to requirements imposed by any Takeover Law and each of them shall
take all necessary steps within its control to exempt (or ensure the continued
exemption of) the transactions contemplated by this Plan from, or if necessary
challenge the validity or applicability of, any applicable Takeover Law, as now
or hereafter in effect.

mutually agreed upon. Headlands and GreenPoint shall also consult with respect
to the character, amount and timing of restructuring charges to be taken by each
of them in connection with the transactions contemplated hereby and shall take
such charges in accordance with GAAP, as may be mutually agreed upon. No party's
representations, warranties and covenants contained in this Plan shall be deemed
to be untrue or breached in any respect for any purpose as a consequence of any
modifications or changes to such policies and practices which may be undertaken
on account of this Section 6.9.
                   ----------- 

        (b)  In the case of Headlands, it agrees to amend any Compensation and
Benefit Plan qualified under Section 401(k) of the Code which offers Headlands
Common Stock as an investment option, as soon as reasonably practicable after
the execution of this Plan, so that no original issue shares of Headlands Common
Stock will be issued under such Compensation and Benefit Plan thereafter .

        6.10.  NYSE Listing.  GreenPoint agrees to use its reasonable best
               ------------

        6.11  Regulatory Applications; Consents.
              --------------------------------- 

        (a)  GreenPoint and Headlands and their respective Subsidiaries shall
cooperate and use their respective reasonable best efforts to prepare all
documentation, to effect all filings as soon as reasonably practicable, but in
no event later than 45 days from the date hereof, and to obtain all permits,
consents, approvals and authorizations of all third parties and Governmental
Authorities necessary to consummate the transactions contemplated by this Plan.
Each of GreenPoint and Headlands shall have the right to review in advance, and
to the extent practicable each will consult with the other, in each case subject
to applicable laws relating to the exchange of 

                                       54
<PAGE>
 
information, with respect to all material written information submitted to any
third party or any Governmental Authority in connection with the transactions
contemplated by this Plan. In exercising the foregoing right, each of the
parties hereto agrees to act reasonably and as promptly as practicable. Each
party hereto agrees that it will consult with the other party hereto with
respect to the obtaining of all material permits, consents, approvals and
authorizations of all third parties and Governmental Authorities necessary or
advisable to consummate the transactions contemplated by this Plan and each
party will keep the other party appraised of the status of material matters
relating to completion of the transactions contemplated hereby.

all information concerning itself, its Subsidiaries, directors, officers and
stockholders and such other matters as may be reasonably necessary or advisable
in connection with any filing, notice or application made by or on behalf of
such other party or any of its Subsidiaries to any third party or Governmental
Authority.

directors of Headlands and its Subsidiaries (each, an "Indemnified Party")
against all costs or expenses (including reasonable attorneys' fees), judgments,
fines, losses, claims, damages or liabilities incurred in connection with any
claim, action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, arising out of actions or omissions occurring
at or prior to the Effective Time (including, without limitation, the
transactions contemplated by this Plan) to the extent that Headlands is
authorized to indemnify (and advance expenses to) its directors under the laws
of the State of California, the Headlands Certificate and the Headlands Bylaws
as in effect on the date hereof; provided that any determination required to be
made with respect to whether an officer's or director's conduct complies with
the standards set forth under California law, the Headlands Certificate and the

                                       55
<PAGE>
 
Headlands Bylaws shall be made by independent counsel (which shall not be
counsel that provides material services to GreenPoint) selected by GreenPoint
and reasonably acceptable to such officer or director; and provided, further,
that in the absence of applicable California judicial precedent to the contrary,
such counsel, in making such determination, shall presume such officer's or
director's conduct complied with such standard and GreenPoint shall have the
burden to demonstrate that such officer's or director's conduct failed to comply
with such standard.

        (b)  Any Indemnified Party wishing to claim indemnification under
Section 6.12(a), upon learning of any claim, action, suit, proceeding or
- ---------------
investigation described above, shall promptly notify GreenPoint thereof;
provided that the failure so to notify shall not affect the obligations of
GreenPoint under Section 6.12(a) unless and to the extent that GreenPoint is
                 ---------------
actually prejudiced as a result of such failure.

        (c)  If GreenPoint or any of its successors or assigns shall consolidate
with or merge into any other entity and shall not be the continuing or surviving
entity of such consolidation or merger or shall transfer all or substantially
all of its assets to any other entity, then and in each case, proper provision
shall be made so that the successors and assigns of GreenPoint shall assume the
obligations set forth in this Section 6.12.
                              ------------ 
        (d)  The provisions of this Section are intended to be for the benefit
of, and shall be enforceable by, each of the Indemnified Parties, their heirs
and their representatives.

Headlands' current directors' and officers' liability insurance covering acts or
omissions occurring prior to the Effective Time with respect to those persons
who are currently covered by Headlands' directors' and officers' liability
insurance policy on terms with respect to such coverage and amount no less
favorable than those of such policy in effect on the date hereof so long as the
annual premium therefor is not in excess of 150% of the aggregate premiums paid
by Headlands in 1998 on an annualized basis for such purpose (which aggregate
premium on an annualized basis has been Previously Disclosed by Headlands), but
if the annual premium therefor so exceeds such amount, the Surviving Corporation
(or an Affiliate thereof) will 

                                       56
<PAGE>
 
obtain as much directors' and officers' liability insurance as can be obtained
for the remainder of such period for a premium not in excess of 150% of the
aggregate premiums paid by Headlands in 1998 on an annualized basis for such
purpose; provided that the Surviving Corporation (or an Affiliate thereof) may
         --------
substitute therefor policies of the Surviving Corporation or its Affiliates
containing terms with respect to coverage and amount no less favorable to such
directors or officers; provided, further, that if the existing or substituted
                       --------  -------
directors' and officers' liability insurance expires, is terminated or canceled
the Surviving Corporation (or an Affiliate thereof) shall obtain directors' and
officers' liability insurance with respect to coverage and amounts no less
favorable than those of such policy in effect on the date hereof for the
remainder of the six-year period so long as the annual premium therefor is not
in excess of 150% of the aggregate premiums paid by Headlands in 1998 on an
annualized basis for such purpose, but if the Surviving Corporation (or an
Affiliate thereof) cannot obtain such coverage for a premium not in excess of
such amount, the Surviving Corporation (or an Affiliate thereof) shall obtain as
much directors' and officers' liability insurance as can be obtained for the
remainder of such period for a premium not in excess of 150% of the aggregate
premiums paid by Headlands in 1998 on an annualized basis for such purpose.

        6.13.  Benefit Plans.
               ------------- 

        (a)  Following the Effective Time, employees of Headlands and its
Subsidiaries shall continue to be provided with benefits under employee benefit
plans that are substantially comparable in the aggregate to those currently
provided by Headlands and its Subsidiaries to such employees. In the event that
following the Effective Time an employee of Headlands or its Subsidiaries is
eligible to be covered under a GreenPoint or GreenPoint Subsidiary medical
insurance plan, such employee (or his or her eligible dependents) shall not be
excluded from coverage under such plan on the basis of a pre-existing condition
that was not also excluded under Headlands' medical insurance plans. In the
event that following the Effective Time an employee of Headlands or its
Subsidiaries is eligible to be covered under an employee benefit plan of
GreenPoint, then for all purposes under each employee benefit plan to be
provided by GreenPoint to employees of Headlands or its Subsidiaries, GreenPoint
shall recognize such employee's prior service with Headlands or its Subsidiaries
(to the same extent such service was recognized under a similar plan 

                                       57
<PAGE>
 
of Headlands or its Subsidiaries), except that such prior service shall not be
counted for the following purposes: (i) eligibility or vesting for purposes of
the non-401(k) and (m) related portions of GreenPoint's Employee Stock Ownership
Plan, (ii) the rate of accrual under GreenPoint's cash balance defined benefit
plan and (iii) eligibility to participate in GreenPoint's retiree medical and
life insurance coverage programs.

        (b)  Prior to the Effective Time, Headlands shall take or cause to be
taken any and all such reasonable actions as may be necessary such that each
outstanding Headlands Stock Option, dividend equivalent right, stock
appreciation right, limited stock appreciation right, restricted stock, deferred
stock and performance share award is not cashed out (whether by payment in cash
or other property) and does not become vested and exercisable or distributable
as a result of the transactions contemplated hereby.

        (c)  From and after the Effective Time, GreenPoint shall, and shall
cause its Subsidiaries to, credit any deductibles and out-of-pocket expenses
that are applicable and/or covered under the Compensation and Benefit Plans, and
are incurred by the employees and their beneficiaries during the portion of the
calendar year prior to participation in the benefit plans provided by
GreenPoint, the Surviving Corporation and the GreenPoint subsidiaries.

        (d)  From and after the Effective Time, GreenPoint shall honor, and
shall cause the Surviving Corporation to honor, in accordance with their terms
all benefits vested as of the date hereof under the Compensation and Benefit
Plans or under other Previously Disclosed agreements, understandings or
arrangements except to the extent any such agreements, understandings or
arrangements are superseded pursuant to any agreements entered into on or after
the date hereof. Nothing herein shall prevent GreenPoint from terminating any
Compensation and Benefit Plan in accordance with its terms and subject to
applicable law.

        (e)  From the date hereof, any employee communications relating to the
Compensation and Benefit Plans to be distributed by Headlands or its
Subsidiaries shall be subject to GreenPoint's prior review and approval, which
approval shall be processed timely and shall not be unreasonably denied.

GreenPoint shall give prompt notice to the other of any fact, event or
circumstance known to it that (i) is reasonably likely, individually or taken
together with all other facts, events and circumstances known to it, to result
in any Material Adverse Effect with respect to it or (ii) would cause or

the end of the month immediately following the month in which the Effective Date
occurred), 30-day combined financial statements as contemplated by and in
accordance with the terms of SEC Accounting Series Release No. 35.

        6.18.  Surviving Corporation Name.  GreenPoint agrees to cause the
               --------------------------

                            STOCK OPTION AGREEMENT
                            ----------------------

            STOCK OPTION AGREEMENT, dated as of December 8, 1998, between
GreenPoint Financial Corp., a Delaware corporation ("Grantee"), and Headlands
Mortgage Company, a California corporation("Issuer").

                                    RECITALS

        A.  Grantee and Issuer have entered into an Agreement and Plan of Merger
(the "Merger Agreement").

        B.  As an inducement to the willingness of Grantee to continue to pursue
the transactions contemplated by the Merger Agreement, Issuer has agreed to
grant Grantee the Option (as hereinafter defined).

        C.  The Board of Directors of Issuer has approved the grant of the
Option and the Merger Agreement prior to the date hereof.

            NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements set forth herein and in the Merger Agreement, the
parties hereto agree as follows:

        1.  (a) Issuer hereby grants to Grantee an unconditional, irrevocable
option (the "Option") to purchase, subject to the terms hereof, up to that
number of fully paid and nonassessable shares of the common stock, without par
value, of Issuer ("Common Stock") equal to 19.9% of the Common Stock issued and
outstanding as of the date hereof at a price per share equal to $16.125 (as
adjusted, the "Option Price"). The number of shares of Common Stock that may be
received upon the exercise of the Option and the Option Price are subject to
adjustment as herein set forth.

            (b) In the event that any shares of Common Stock are either (i)
issued or otherwise become outstanding after the date of this Agreement (other
than pursuant to this Agreement and other than pursuant to an event described in
Section 5(a) hereof) or (ii) redeemed, repurchased, retired or otherwise cease
- ------------
to be outstanding after the date of this Agreement, the number of shares of
Common Stock subject to the Option shall be increased or decreased, as
appropriate, so that, after such issuance or such redemption, repurchase,
retirement or other action, such number together with any shares of Common Stock
previously issued pursuant hereto, equals 19.9% of the number of shares of
Common 

                                      A-1
<PAGE>
 
Stock then issued and outstanding without giving effect to any shares subject or
issued pursuant to the Option. Nothing contained in this Section l(b) or
                                                         ------------
elsewhere in this Agreement shall be deemed to authorize Issuer to issue shares
in breach of any provision of the Merger Agreement.

        2.  (a) The Holder (as hereinafter defined) may exercise the Option, in
whole or part, if, but only if, both an Initial Triggering Event (as hereinafter
defined) and a Subsequent Triggering Event (as hereinafter defined) shall have
occurred prior to the occurrence of an Exercise Termination Event (as
hereinafter defined), provided that the Holder shall have sent the written
notice of such exercise (as provided in subsection (e) of this Section 2) within
                                                               ---------
six (6) months following such Subsequent Triggering Event (or such later period
as provided in Section 10). Each of the following shall be an Exercise
               ----------
Termination Event: (i) the Effective Time (as defined in the Merger Agreement);
(ii) termination of the Merger Agreement in accordance with the provisions
thereof if such termination occurs prior to the occurrence of an Initial
Triggering Event except a termination by Grantee pursuant to Section 8.1(b)
                                                             -------------
(unless the breach giving rise to such termination was not willful) or Section
                                                                       -------
8.1(e) of the Merger Agreement or by Grantee or Issuer pursuant to Section
- -----                                                              -------
8.1(d)(ii) of the Merger Agreement (each, a "Listed Termination"); or (iii) the
- ---------
passage of fifteen (15) months (or such longer period as provided in Section 10)
                                                                     ----------
after termination of the Merger Agreement if such termination follows the
occurrence of an Initial Triggering Event or is a Listed Termination. The term
"Holder" shall mean the holder or holders of the Option. Notwithstanding
anything to the contrary contained herein, (i) the Option may not be exercised
at any time when Grantee shall be in material breach of any of its
representations, warranties, covenants or agreements contained in the Merger
Agreement such that Issuer shall be entitled to terminate the Merger Agreement
pursuant to Section 8.1(b) thereof and (ii) this Agreement shall automatically
            -------------
terminate upon the proper termination of the Merger Agreement by Issuer pursuant
to Section 8.1(b) thereof as a result of the material breach by Grantee of its
   -------------
representations, warranties, covenants or agreements contained in the Merger
Agreement.
 
            (b) The term "Initial Triggering Event" shall mean any of the
following events or transactions occurring on or after the date hereof:

                (i)  Issuer or Headlands Mortgage Securities, Inc. (which Issuer
represents is its only subsidiary) (the "Issuer Subsidiary"), without having
received Grantee's prior written consent, shall have entered into an agreement
to engage in an Acquisition Transaction (as hereinafter defined) with any person
(the term "person" for purposes of this Agreement having the meaning assigned
thereto in Sections 3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934,
as amended (the "1934 Act"), and the rules and regulations thereunder) other
than Grantee or any of its Subsidiaries (each a "Grantee Subsidiary") or the
Board of Directors of Issuer (the "Issuer Board") shall have recommended that
the shareholders of Issuer approve or accept any Acquisition Transaction other
than as contemplated by the Merger Agreement. For purposes of this Agreement,
(a) "Acquisition Transaction" shall mean (x) a merger or consolidation, or any
similar transaction, involving Issuer or the Issuer Subsidiary (other than
mergers, consolidations or similar transactions involving solely Issuer and/or
one or more wholly-owned Subsidiaries of the Issuer, provided, any such
transaction is not entered into in violation of the terms of the Merger
Agreement), (y) a purchase, lease or other acquisition of all or any substantial
part of the assets of Issuer or the Issuer Subsidiary, or (z) a purchase or
other acquisition (including by way of merger, consolidation, share exchange or
otherwise) of securities representing 10% or more of the voting power of Issuer
or the Issuer Subsidiary and (b) "Subsidiary" shall have the meaning set forth
in Rule 12b-2 under the 1934 Act;

                (ii) Any person other than the Grantee or any Grantee Subsidiary
shall have acquired after the date hereof beneficial ownership or the right to
acquire beneficial ownership of 10% or more of the outstanding shares of Common
Stock (the term "beneficial ownership" for purposes of this Agreement having the
meaning assigned thereto in Section 13(d) of the 1934 Act, and the rules and
regulations thereunder);

                (iii) The shareholders of Issuer shall have voted and failed to
approve the Merger Agreement and the Merger at a meeting which has been held for
that purpose or any adjournment or postponement thereof, or such meeting shall
not have been held in violation of the Merger Agreement or shall have been
cancelled prior to termination of the Merger Agreement if, prior to such meeting
(or if such meeting shall not have been held or shall have been cancelled, prior
to such termination), it shall have been publicly announced that any person
(other than Grantee or 

                                      A-3
<PAGE>
 
any of its Subsidiaries) shall have made, or disclosed an intention to make, a
bona fide proposal to engage in an Acquisition Transaction;

                (iv) The Issuer Board shall have withdrawn or modified (or
publicly announced its intention to withdraw or modify) in any manner adverse in
any respect to Grantee its recommendation that the shareholders of Issuer
approve the transactions contemplated by the Merger Agreement, or Issuer or the
Issuer Subsidiary shall have authorized, recommended, proposed (or publicly
announced its intention to authorize, recommend or propose) an agreement to
engage in an Acquisition Transaction with any person other than Grantee or a
Grantee Subsidiary;

                (v) Any person other than Grantee or any Grantee Subsidiary
shall have made a bona fide proposal to Issuer or its shareholders to engage in
an Acquisition Transaction and such proposal shall have been publicly announced;

                (vi) Any person other than Grantee or any Grantee Subsidiary
shall have filed with the SEC a registration statement or tender offer materials
with respect to a potential exchange or tender offer that would constitute an
Acquisition Transaction (or filed a preliminary proxy statement with the SEC
with respect to a potential vote by its shareholders to approve the issuance of
shares to be offered in such an exchange offer);

                (vii) Issuer shall have willfully breached any covenant or
obligation contained in the Merger Agreement in anticipation of engaging in an
Acquisition Transaction, and following such breach Grantee would be entitled to
terminate the Merger Agreement (whether immediately or after the giving of
notice or passage of time or both); or

                (viii) Any person other than Grantee or any Grantee Subsidiary
shall have filed an application or notice with the Board of Governors of the
Federal Reserve System (the "Federal Reserve Board") or other federal or state
bank regulatory or antitrust authority, which application or notice has been
accepted for processing, for approval to engage in an Acquisition Transaction
with Issuer.

            (c) The term "Subsequent Triggering Event" shall mean any of the
following events or transactions occurring after the date hereof:

                                      A-4
<PAGE>
 
                (i) The acquisition by any person (other than Grantee or any
Grantee Subsidiary) of beneficial ownership of 20% or more of the then
outstanding Common Stock; or

                (ii) The occurrence of the Initial Triggering Event described in
clause (i) of subsection (b) of this Section 2, except that the percentage
referred to in clause (z) of the second sentence thereof shall be 20%.

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

            (e) In the event the Holder is entitled to and wishes to exercise
the Option (or any portion thereof), 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 shares it will purchase pursuant to such exercise and (ii) a
place and date not earlier than three business days nor later than 90 days from
the Notice Date for the closing of such purchase (the "Closing Date"); provided,
that if prior notification to or approval of the Federal Reserve Board or any
other regulatory or antitrust agency is required in connection with such
purchase, the Holder shall promptly file the required notice or application for
approval, shall promptly notify Issuer of such filing, and shall expeditiously
process the same and the period of time that otherwise would run pursuant to
this sentence shall run instead from the date on which any required notification
periods have expired or been terminated or such approvals have been obtained and
any requisite waiting period or periods shall have passed. Any exercise of the
Option shall be deemed to occur on the Notice Date relating thereto.

            (f) At the closing referred to in subsection (e) of this Section 2,
the Holder shall (i) pay to Issuer the aggregate purchase price for the shares
of Common Stock purchased pursuant to the exercise of the Option in immediately
available funds by wire transfer to a bank account designated by Issuer and (ii)
present and surrender this Agreement to Issuer at its principal executive
offices, provided that the failure or refusal of the Issuer to designate such a
bank account or accept surrender of this Agreement shall not preclude the Holder
from exercising the Option.

                                      A-5
<PAGE>
 
            (g) At such closing, simultaneously with the delivery of immediately
available funds as provided in subsection (f) of this Section 2, Issuer shall
deliver to the Holder a certificate or certificates representing the number of
shares of Common Stock purchased by the Holder and, if the Option should be
exercised in part only, a new Option evidencing the rights of the Holder thereof
to purchase the balance of the shares purchasable hereunder.

            (h) Certificates for Common Stock delivered at a closing hereunder
may be endorsed with a restrictive legend that shall read substantially as
follows:

                "The transfer of the shares represented by this certificate is
     subject to certain provisions of an agreement, dated as of December 8,
     1998, between the registered holder hereof and Headlands Mortgage Company
     and to resale restrictions arising under the Securities Act of 1933, as
     amended. A copy of such agreement is on file at the principal office of
     Headlands Mortgage Company and will be provided to the holder hereof
     without charge upon receipt by Headlands Mortgage Company of a written
     request therefor."

It is understood and agreed that: (i) the reference to the resale restrictions
of the Securities Act of 1933, as amended (the "1933 Act") in the above legend
shall be removed by delivery of substitute certificate(s) without such reference
if the 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, to the effect that such legend is not required for
purposes of the 1933 Act; (ii) the reference to the provisions of this Agreement
in the above legend shall be removed by delivery of substitute certificate(s)
without such reference if the shares have been sold or transferred in compliance
with the provisions of this Agreement and under circumstances that do not
require the retention of such reference in the opinion of Counsel to the Holder,
in form and substance reasonably satisfactory to Issuer, and (iii) the legend
shall be removed in its entirety if the conditions in the preceding clauses (i)
and (ii) are both satisfied.  In addition, such certificates shall bear any
other legend as may be required by law.

                                      A-6
<PAGE>
 
            (i) Upon the giving by the Holder to Issuer of the written notice of
exercise of the Option provided for under subsection (e) of this Section 2 and
the tender of the applicable purchase price in immediately available funds on
the Closing Date, the Holder shall be deemed to be the holder of record of the
shares of 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 Common Stock shall not then be actually delivered to
the 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, issue and delivery of stock certificates under
this Section 2 in the name of the Holder or its assignee, transferee or
designee.

        3.  Issuer agrees:  (i) that it shall at all times maintain, free from
preemptive rights, sufficient authorized but unissued or treasury shares of
Common Stock so that the Option may be exercised without additional
authorization of Common Stock after giving effect to all other options,
warrants, convertible securities and other rights to purchase 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 (x) complying with all applicable premerger notification, reporting
and waiting period requirements specified in 15 U.S.C. Section 18a and
regulations promulgated thereunder and (y) in the event, under the Bank Holding
Company Act of 1956, as amended (the "BHCA"), or the Change in Bank Control Act
of 1978, as amended, or any state or other federal banking law, prior approval
of or notice to the Federal Reserve Board or to any state or other federal
regulatory authority is necessary before the Option may be exercised,
cooperating fully with the Holder in preparing such applications or notices and
providing such information to the Federal Reserve Board or such state or other
federal regulatory authority as they may require) in order to permit the Holder
to exercise the Option and Issuer duly and effectively to issue shares of Common
Stock pursuant hereto; and (iv) promptly to take all action provided herein to
protect the rights of the Holder against dilution.

                                      A-7
<PAGE>
 
        4.  This Agreement (and the Option granted hereby) are exchangeable,
without expense, at the reasonable request of the 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, on the same terms and subject to the same conditions as are
set forth herein, in the aggregate the same number of shares of Common Stock
purchasable hereunder.  The terms "Agreement" and "Option" as used herein
include any 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.

        5.  In addition to the adjustment in the number of shares of Common
Stock that are purchasable upon exercise of the Option pursuant to Section 1 of
                                                                   ---------   
this Agreement, the number of shares of Common Stock purchasable upon the
exercise of the Option and the Option Price shall be subject to adjustment from
time to time as provided in this Section 5.
                                 --------- 
            (a) In the event of any change in, or distributions in respect of,
the Common Stock by reason of stock dividends, split-ups, mergers,
recapitalizations, combinations, subdivisions, conversions, exchanges of shares
or the like, the type and number of shares of Common Stock purchasable upon
exercise hereof shall be appropriately adjusted and proper provision shall be
made so that, in the event that any additional shares of Common Stock are issued
or otherwise become outstanding as a result of any such change (other than
pursuant to an exercise of the Option), the number of shares of Common Stock
that remain subject to the Option shall be increased so that, after such
issuance and together with shares of Common Stock previously issued pursuant to
the exercise of the Option (as adjusted on account of any of the foregoing
changes in the Common Stock), it equals 19.9% of the number of shares of Common
Stock then issued and outstanding.

                                      A-8
<PAGE>
 
            (b) Whenever the number of shares of Common Stock purchasable upon
exercise hereof is adjusted as provided in this Section 5, the Option Price
                                                ---------
shall be adjusted by multiplying the Option Price by a fraction, the numerator
of which shall be equal to the number of shares of Common Stock purchasable
prior to the adjustment and the denominator of which shall be equal to the
number of shares of Common Stock purchasable after the adjustment.

        6.  Upon the occurrence of a Subsequent Triggering Event that occurs
prior to an Exercise Termination Event, Issuer shall, at the request of Grantee
delivered within twelve (12) months (or such later period as provided in Section
                                                                         -------
10) of such Subsequent Triggering Event (whether on its own behalf or on behalf
- --                                                                             
of any subsequent holder of this Option (or part thereof) or any of the shares
of Common Stock issued pursuant hereto), promptly prepare, file and keep current
a registration statement under the 1933 Act covering any shares issued and
issuable pursuant to this Option and shall use its reasonable best efforts to
cause such registration statement to become effective and remain current in
order to permit the sale or other disposition of any shares of Common Stock
issued upon total or partial exercise of this Option ("Option Shares") in
accordance with any reasonable plan of disposition requested by Grantee. Issuer
will use its reasonable best efforts to cause such registration statement
promptly to become effective and then to remain effective for such period not in
excess of 180 days from the day such registration statement first becomes
effective or such shorter time as may be reasonably necessary to effect such
sales or other dispositions.  Grantee shall have the right to demand two such
registrations.  The Issuer shall bear the costs of such registrations
(including, but not limited to, Issuer's attorneys' fees, printing costs and
filing fees, except for underwriting discounts or commissions, brokers' fees and
the fees and disbursements of Grantee's counsel related thereto).  The foregoing
notwithstanding, if, at the time of any request by Grantee for registration of
Option Shares as provided above, Issuer is in registration with respect to an
underwritten public offering by Issuer of shares of Common Stock, and if in the
good faith judgment of the managing underwriter or managing underwriters, or, if
none, the sole underwriter or underwriters, of such offering the offer and sale
of the Option Shares would interfere with the successful marketing of the shares
of Common Stock offered by Issuer, the number of Option Shares otherwise to be
covered in the registration statement contemplated hereby may be reduced;
provided, however, that after 

                                      A-9
<PAGE>
 
any such required reduction the number of Option Shares to be included in such
offering for the account of the Holder shall constitute at least 25% of the
total number of shares to be sold by the Holder and Issuer in the aggregate; and
provided further, however, that if such reduction occurs, then Issuer shall file
a registration statement for the balance as promptly as practicable thereafter
as to which no reduction pursuant to this Section 6 shall be permitted or occur
                                          ---------
and the Holder shall thereafter be entitled to one additional registration and
the twelve (12) month period referred to in the first sentence of this section
shall be increased to twenty-four (24) months. Each such Holder shall provide
all information reasonably requested by Issuer for inclusion in any registration
statement to be filed hereunder. If requested by any such Holder in connection
with such registration, Issuer shall become a party to any underwriting
agreement relating to the sale of such shares, but only to the extent of
obligating itself in respect of representations, warranties, indemnities and
other agreements customarily included in such underwriting agreements for
Issuer. Upon receiving any request under this Section 6 from any Holder, Issuer
                                              ---------
agrees to send a copy thereof to any other person known to Issuer to be entitled
to registration rights under this Section 6, in each case by promptly mailing
                                  ---------
the same, postage prepaid, to the address of record of the persons entitled to
receive such copies. Notwithstanding anything to the contrary contained herein,
in no event shall the number of registrations that Issuer is obligated to effect
be increased by reason of the fact that there shall be more than one Holder as a
result of any assignment or division of this Agreement.

        7.  (a) At any time after the occurrence of a Repurchase Event (as
defined below) (i) at the request of the Holder, delivered prior to an Exercise
Termination Event (or such later period as provided in Section 10), Issuer (or
                                                       ----------             
any successor thereto) shall repurchase the Option from the Holder at a price
(the "Option Repurchase Price") equal to the amount by which (A) the
market/offer price (as defined below) exceeds (B) the Option Price, multiplied
by the number of shares for which this Option may then be exercised and (ii) at
the request of the owner of Option Shares from time to time (the "Owner"),
delivered prior to an Exercise Termination Event (or such later period as
provided in Section 10), Issuer (or any successor thereto) shall repurchase such
            ----------                                                          
number of the Option Shares from the Owner as the Owner shall designate at a
price (the "Option Share Repurchase Price") equal to the market/offer price
multiplied by the number 

                                     A-10
<PAGE>
 
of Option Shares so designated. Anything to the contrary notwithstanding, the
Option Share Repurchase Price shall not be less than $13.93 million in the
aggregate. The term "market/offer price" shall mean the highest of (i) the price
per share of Common Stock at which a tender or exchange offer therefor has been
made, (ii) the price per share of Common Stock to be paid by any third party
pursuant to an agreement with Issuer, (iii) the highest closing price for shares
of Common Stock within the three month period immediately preceding the date the
Holder gives notice of the required repurchase of this Option or the Owner gives
notice of the required repurchase of Option Shares, as the case may be, or (iv)
in the event of a sale of all or any substantial part of Issuer's assets or
deposits, the sum of the net price paid in such sale for such assets or deposits
and the current market value of the remaining net assets of Issuer as determined
by a nationally recognized investment banking firm selected by the Holder or the
Owner, as the case may be, and reasonably acceptable to Issuer, divided by the
number of shares of Common Stock of Issuer outstanding at the time of such sale.
In determining the market/offer price, the value of consideration other than
cash shall be determined by a nationally recognized investment banking firm
selected by the Holder or Owner, as the case may be, and reasonably acceptable
to Issuer.
 
            (b) The Holder and the Owner, as the case may be, may exercise its
right to require Issuer to repurchase the Option and any Option Shares pursuant
to this Section 7 by surrendering for such purpose to Issuer, at its principal
        ---------
office, a copy of this Agreement or certificates for Option Shares, as
applicable, accompanied by a written notice or notices stating that the Holder
or the Owner, as the case may be, elects to require Issuer to repurchase this
Option and/or the Option Shares in accordance with the provisions of this
Section 7. As promptly as practicable, and in any event within fifteen calendar
- ---------
days after the surrender of the Option and/or certificates representing Option
Shares and the receipt of such notice or notices relating thereto, Issuer shall
deliver or cause to be delivered to the Holder the Option Repurchase Price
and/or to the Owner the Option Share Repurchase Price therefor or the portion
thereof that Issuer is not then prohibited under applicable law and regulation
from so delivering.

            (c) To the extent that Issuer is prohibited under applicable law or
regulation from repurchasing the Option and/or the Option Shares in full, Issuer
shall immediately so notify the

                                     A-11
<PAGE>
 
Holder and/or the Owner and thereafter deliver or cause to be delivered, from
time to time, to the Holder and/or the Owner, as appropriate, the portion of the
Option Repurchase Price and the Option Share Repurchase Price, respectively,
that it is no longer prohibited from delivering, within fifteen calendar days
after the date on which Issuer is no longer so prohibited; provided, however,
that if Issuer at any time after delivery of a notice of repurchase pursuant to
paragraph (b) of this Section 7 is prohibited under applicable law or regulation
                      ---------
from delivering to the Holder and/or the Owner, as appropriate, the Option
Repurchase Price and the Option Share Repurchase Price, respectively, in full
(and Issuer hereby undertakes to use its reasonable best efforts to obtain all
required regulatory and legal approvals and to file any required notices as
promptly as practicable in order to accomplish such repurchase), the Holder or
Owner may revoke its notice of repurchase of the Option and/or the Option Shares
whether in whole or to the extent of the prohibition, whereupon, in the latter
case, Issuer shall promptly (i) deliver to the Holder and/or the Owner, as
appropriate, that portion of the Option Repurchase Price and/or the Option Share
Repurchase Price that Issuer is not prohibited from delivering; and (ii)
deliver, as appropriate, either (A) to the Holder, a new Agreement evidencing
the right of the Holder to purchase that number of shares of Common Stock
obtained by multiplying the number of shares of Common Stock for which the
surrendered Agreement was exercisable at the time of delivery of the notice of
repurchase by a fraction, the numerator of which is the Option Repurchase Price
less the portion thereof theretofore delivered to the Holder and the denominator
of which is the Option Repurchase Price, and/or (B) to the Owner, a certificate
for the Option Shares it is then so prohibited from repurchasing. If an Exercise
Termination Event shall have occurred prior to the date of the notice by Issuer
described in the first sentence of this subsection (c), or shall be scheduled to
occur at any time before the expiration of a period ending on the thirtieth day
after such date, the Holder shall nonetheless have the right to exercise the
Option until the expiration of such 30-day period.

            (d) For purposes of this Section 7, a "Repurchase Event" shall be
                                     ---------
deemed to have occurred upon the occurrence of any of the following events or
transactions after the date hereof:

                (i) the acquisition by any person (other than Grantee or any
     Grantee Subsidiary) of beneficial ownership of 50% or more of the then
     outstanding Common Stock; or

                                     A-12
<PAGE>
 
                (ii) the consummation of any Acquisition Transaction described
in Section 2(b)(i) hereof, except that the percentage referred to in clause (z)
shall be 50%.

The parties agree that Issuer's obligation to repurchase the Option and/or the
Option Shares under this Section 7 shall not terminate upon the occurrence of an
Exercise Termination Event unless no Subsequent Triggering Event shall have
occurred prior to an Exercise Termination Event.

        8.  (a) In the event that prior to an Exercise Termination Event,
Issuer shall enter into an agreement (i) to consolidate with or merge into any
person, other than Grantee or a Grantee Subsidiary, or engage in a plan of
exchange with any person, other than Grantee or a Grantee Subsidiary and Issuer
shall not be the continuing or surviving corporation of such consolidation or
merger or the acquirer in such plan of exchange, (ii) to permit any person,
other than Grantee or a Grantee Subsidiary, to merge into Issuer or be acquired
by Issuer in a plan of exchange and Issuer shall be the continuing or surviving
or acquiring corporation, but, in connection with such merger or plan of
exchange, the then outstanding shares of Common Stock shall be changed into or
exchanged for stock or other securities of any other person or cash or any other
property or the then outstanding shares of Common Stock shall after such merger
or plan of exchange represent less than 50% of the outstanding shares and share
equivalents of the merged or acquiring company, or (iii) to sell or otherwise
transfer all or a substantial part of its or the Issuer Subsidiary's assets or
deposits to any person, other than Grantee or a Grantee Subsidiary, then, and in
each such case, the agreement governing such transaction shall make proper
provision 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
the Holder, of either (x) the Acquiring Corporation (as hereinafter defined) or
(y) any person that controls the Acquiring Corporation.
 
            (b) The following terms have the meanings indicated:

                (i) "Acquiring Corporation" shall mean (i) the continuing or
surviving person of a consolidation or merger with Issuer (if other than
Issuer), (ii) the acquiring person in a plan of exchange in which Issuer is
acquired, (iii) the Issuer in

                                     A-13
<PAGE>
 
a merger or plan of exchange in which Issuer is the continuing or surviving or
acquiring person, and (iv) the transferee of all or a substantial part of
Issuer's assets or deposits (or the assets or deposits of the Issuer
Subsidiary).

                (ii) "Substitute Common Stock" shall mean the common stock
issued by the issuer of the Substitute Option upon exercise of the Substitute
Option.

                (iii) "Assigned Value" shall mean the market/offer price, as
defined in Section 7.
           --------- 

                (iv) "Average Price" shall mean the average closing price of a
share of the Substitute Common Stock for 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 the person merging into Issuer or by any company which
controls or is controlled by such person, as the Holder may elect.

            (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 the Holder. The issuer of the Substitute Option shall
also enter into an agreement with the then Holder or Holders of the Substitute
Option in substantially the same form as this Agreement (after giving effect for
such purpose to the provisions of Section 9), which agreement shall be
                                  ---------
applicable to the Substitute Option.

            (d) The Substitute Option shall be exercisable for such number of
shares of Substitute Common Stock as is equal to the Assigned Value multiplied
by the number of shares of Common Stock for which the Option was exercisable
immediately prior to the event described in the first sentence of Section 8(a),
                                                                  -----------
divided by the Average Price. The exercise price of the Substitute Option per
share of Substitute Common Stock shall then be equal to the Option Price
multiplied by a fraction, the numerator of which shall be the number of shares
of Common Stock for which the Option was exercisable immediately prior to the
event described in the first sentence of Section 8(a) and the denominator of
                                          ----------

                                     A-14
<PAGE>
 
which shall be the number of shares of Substitute Common Stock for which the
Substitute Option is exercisable.

            (e) In no event, pursuant to any of the foregoing paragraphs, shall
the Substitute Option be exercisable for more than 19.9% 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 shares of Substitute Common Stock outstanding prior to exercise but for
this clause (e), the issuer of the Substitute Option (the "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 this
clause (e) over (ii) the value of the Substitute Option after giving effect to
the limitation in this clause (e). This difference in value shall be determined
by a nationally recognized investment banking firm selected by the Holder.

            (f) Issuer shall not enter into any transaction described in
subsection (a) of this Section 8 unless the Acquiring Corporation and any person
                       ---------
that controls the Acquiring Corporation assume in writing all the obligations of
Issuer hereunder.

        9.  (a) At the request of the holder of the Substitute Option (the
"Substitute Option Holder"), the Substitute Option Issuer shall repurchase the
Substitute Option from the Substitute Option Holder at a price (the "Substitute
Option Repurchase Price") equal to the amount by which (i) the Highest Closing
Price (as hereinafter defined) exceeds (ii) the exercise price of the Substitute
Option, multiplied by the number of shares of Substitute Common Stock for which
the Substitute Option may then be exercised, and at the request of the owner
(the "Substitute Share Owner") of shares of Substitute Common Stock (the
"Substitute Shares"), the Substitute Option Issuer shall repurchase the
Substitute Shares at a price (the "Substitute Share Repurchase Price") equal to
the Highest Closing Price multiplied by the number of Substitute Shares so
designated. The term "Highest Closing Price" shall mean the highest closing
price for shares of Substitute Common Stock within the six-month period
immediately preceding the date the Substitute Option Holder gives notice of the
required repurchase of the Substitute Option or the Substitute Share Owner gives
notice of the required repurchase of the Substitute Shares, as applicable.

                                     A-15
<PAGE>
 
            (b) The Substitute Option Holder and the Substitute Share Owner, as
the case may be, may exercise its respective rights to require the Substitute
Option Issuer to repurchase the Substitute Option and the Substitute Shares
pursuant to this Section 9 by surrendering for such purpose to the Substitute
                 ---------
Option Issuer, at its principal office, the agreement for such Substitute Option
(or, in the absence of such an agreement, a copy of this Agreement) and/or
certificates for Substitute Shares accompanied by a written notice or notices
stating that the Substitute Option Holder or the Substitute Share Owner, as the
case may be, elects to require the Substitute Option Issuer to repurchase the
Substitute Option and/or the Substitute Shares in accordance with the provisions
of this Section 9. As promptly as practicable and in any event within five
        ---------
business days after the surrender of the Substitute Option and/or certificates
representing Substitute Shares and the receipt of such notice or notices
relating thereto, the Substitute Option Issuer shall deliver or cause to be
delivered to the Substitute Option Holder the Substitute Option Repurchase Price
and/or to the Substitute Share Owner the Substitute Share Repurchase Price
therefor or the portion thereof which the Substitute Option Issuer is not then
prohibited under applicable law and regulation from so delivering.

            (c) To the extent that the Substitute Option Issuer is prohibited
under applicable law or regulation from repurchasing the Substitute Option
and/or the Substitute Shares in part or in full, the Substitute Option Issuer
shall immediately so notify the Substitute Option Holder and/or the Substitute
Share Owner and thereafter deliver or cause to be delivered, from time to time,
to the Substitute Option Holder and/or the Substitute Share Owner, as
appropriate, the portion of the Substitute Option Repurchase Price and/or the
Substitute Share Repurchase Price, respectively, which it is no longer
prohibited from delivering, within five (5) business days after the date on
which the Substitute Option Issuer is no longer so prohibited; provided,
however, that if the Substitute Option Issuer is at any time after delivery of a
notice of repurchase pursuant to subsection (b) of this Section 9 prohibited
                                                        ---------
under applicable law or regulation from delivering to the Substitute Option
Holder and/or the Substitute Share Owner, as appropriate, the Substitute Option
Repurchase Price and the Substitute Share Repurchase Price, respectively, in
full (and the Substitute Option Issuer shall use its reasonable best efforts to
receive all required regulatory and legal approvals as promptly as practicable
in order to accomplish such repurchase), the Substitute Option Holder and/or

                                     A-16
<PAGE>
 
Substitute Share Owner may revoke its notice of repurchase of the Substitute
Option or the Substitute Shares either in whole or to the extent of prohibition,
whereupon, in the latter case, the Substitute Option Issuer shall promptly (i)
deliver to the Substitute Option Holder or Substitute Share Owner, as
appropriate, that portion of the Substitute Option Repurchase Price or the
Substitute Share Repurchase Price that the Substitute Option Issuer is not
prohibited from delivering; and (ii) deliver, as appropriate, either (A) to the
Substitute Option Holder, a new Substitute Option evidencing the right of the
Substitute Option Holder to purchase that number of shares of the Substitute
Common Stock obtained by multiplying the number of shares of the Substitute
Common Stock for which the surrendered Substitute Option was exercisable at the
time of delivery of the notice of repurchase by a fraction, the numerator of
which is the Substitute Option Repurchase Price less the portion thereof
theretofore delivered to the Substitute Option Holder and the denominator of
which is the Substitute Option Repurchase Price, and/or (B) to the Substitute
Share Owner, a certificate for the Substitute Option Shares it is then so
prohibited from repurchasing. If an Exercise Termination Event shall have
occurred prior to the date of the notice by the Substitute Option Issuer
described in the first sentence of this subsection (c), or shall be scheduled to
occur at any time before the expiration of a period ending on the thirtieth day
after such date, the Substitute Option Holder shall nevertheless have the right
to exercise the Substitute Option until the expiration of such 30-day period.

        10. The 30-day, 6-month, 12-month, 18-month or 24-month periods for
exercise of certain rights under Sections 2, 6, 7, 9, 12 and 14 shall be
                                 ------------------------------         
extended: (i) to the extent necessary to obtain all regulatory approvals for the
exercise of such rights (for so long as the Holder, Owner, Substitute Option
Holder or Substitute Share Owner, as the case may be, is using commercially
reasonable efforts to obtain such regulatory approvals), and for the expiration
of all statutory waiting periods; (ii) during the pendency of any temporary
restraining order, injunction or other legal bar to exercise of such rights; and
(iii) to the extent necessary to avoid liability under Section 16(b) of the 1934
Act by reason of such exercise.

        11. Issuer hereby represents and warrants to Grantee as follows:

                                     A-17
<PAGE>
 
            (a) 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
Issuer Board prior to the date hereof 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) Issuer has taken all necessary corporate action to authorize and
reserve and to 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
Common Stock equal to the maximum number of shares of Common Stock at any time
and from time to time issuable hereunder, and all such shares, upon issuance
pursuant thereto, will be duly authorized, validly issued, fully paid,
nonassessable, and will be delivered free and clear of all claims, liens,
encumbrance and security interests and not subject to any preemptive rights.

        12. Grantee hereby represents and warrants to Issuer as follows:

            (a) Grantee has all requisite corporate power and authority to enter
into this Agreement and, subject to any approvals or consents to herein, to
consummate the transactions contemplated hereby. 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.
This Agreement has been duly executed and delivered by Grantee.

            (b) The Option is not being, and any shares of Common Stock or other
securities acquired by Grantee upon exercise of the Option will not be, acquired
with a view to the public distribution thereof and will not be transferred or
otherwise disposed of except in a transaction registered or exempt from
registration under the 1933 Act.

        13. Neither of the parties hereto may assign any of its rights or
obligations under this Agreement or the Option created hereunder to any other
person, without the express written 

                                     A-18
<PAGE>
 
consent of the other party, except that in the event an Initial Triggering Event
shall have occurred prior to an Exercise Termination Event, Grantee, subject to
the express provisions hereof, may assign in whole or in part its rights and
obligations hereunder; provided, however, that until the date that is five days
following the date on which the Federal Reserve Board has approved an
application by Grantee to acquire the shares of Common Stock subject to the
Option, Grantee may not assign its rights under the Option except in (i) a
widely dispersed public distribution, (ii) a private placement in which no one
party acquires the right to purchase in excess of 2% of the voting shares of
Issuer, (iii) an assignment to a single party (e.g., a broker or investment
banker) for the purpose of conducting a widely dispersed public distribution on
Grantee's behalf or (iv) any other manner approved by the Federal Reserve Board.

        14. Each of Grantee and Issuer will use its reasonable best efforts to
make all filings with, and to obtain consents of, all third parties and
governmental authorities necessary to the consummation of the transactions
contemplated by this Agreement, including, without limitation, applying to the
Federal Reserve Board under the BHCA for approval to acquire the shares issuable
hereunder, but Grantee shall not be obligated to apply to state banking
authorities for approval to acquire the shares of Common Stock issuable
hereunder until such time, if ever, as it deems appropriate to do so.

        15. (a) Grantee may, at any time following a Repurchase Event and prior
to the occurrence of an Exercise Termination Event (or such later period as
provided in Section 10), relinquish the Option (together with any Option Shares
            ----------                                                         
issued to and then owned by Grantee) to Issuer in exchange for a cash fee equal
to the Surrender Price (as hereinafter defined); provided, however, that Grantee
may not exercise its rights pursuant to this Section 14 if Issuer has
                                             ----------              
repurchased the Option (or any portion thereof) or any Option Shares pursuant to
                                                                                
Section 7.  The "Surrender Price" shall be equal to $13.93 million (i) plus, if
- ---------                                                                      
applicable, Grantee's purchase price with respect to any Option Shares and (ii)
minus, if applicable, the excess of (B) the net cash amounts, if any, received
by Grantee pursuant to the arms' length sale of Option Shares (or any other
securities into which such Option Shares were converted or exchanged) to any
unaffiliated party, over (B) Grantee's purchase price of such Option Shares.

                                     A-19
<PAGE>
 
            (b) Grantee may exercise its right to relinquish the Option and any
Option Shares pursuant to this Section 15 by surrendering to Issuer, at its
principal office, a copy of this Agreement together with certificates for Option
Shares, if any, accompanied by a written notice stating (i) that Grantee elects
to relinquish the Option and Option Shares, if any, in accordance with the
provisions of this Section 15 and (ii) the Surrender Price. The Surrender Price
                   ----------
shall be payable in immediately available funds on or before the second business
day following receipt of such notice by Issuer.

            (c) To the extent that Issuer is prohibited under applicable law or
regulation from paying the Surrender Price to Grantee in full, Issuer shall
immediately so notify Grantee and thereafter deliver or cause to be delivered,
from time to time, to Grantee, the portion of the Surrender Price that it is no
longer prohibited from paying, within five business days after the date on which
Issuer is no longer so prohibited; provided, however, that if Issuer at any time
after delivery of a notice of surrender pursuant to paragraph (b) of this
Section 15 is prohibited under applicable law or regulation from paying to
- ----------
Grantee the Surrender Price in full, (i) Issuer shall (A) use its reasonable
best efforts to obtain all required regulatory and legal approvals and to file
any required notices as promptly as practicable in order to make such payments,
(B) within five days of the submission or receipt of any documents relating to
any such regulatory and legal approvals, provide Grantee with copies of the
same, and (c) keep Grantee advised of both the status of any such request for
regulatory and legal approvals, as well as any discussions with any relevant
regulatory or other third party reasonably related to the same and (ii) Grantee
may revoke such notice of surrender by delivery of a notice of revocation to
Issuer and, upon delivery of such notice of revocation, the Exercise Termination
Date shall be extended to a date six months from the date on which the Exercise
Termination Date would have occurred if not for the provisions of this Section
                                                                       -------
15(c) (during which period Grantee may exercise any of its rights hereunder,

including any and all rights pursuant to this Section 15).
                                              ----------

        16. The parties hereto acknowledge that damages would be an inadequate
remedy for a breach of this Agreement by either party hereto and that the
obligations of the parties hereto shall be enforceable by either party hereto
through injunctive or other equitable relief.  In connection therewith both
parties waive the posting of any bond or similar requirement.

        17. If any term, provision, covenant or restriction contained in this
Agreement is held by a court or a federal or state regulatory agency of
competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions and covenants and restrictions contained in 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 agency determines
that the Holder is not permitted to acquire, or Issuer is not permitted to
repurchase pursuant to Section 7, the full number of shares of Common Stock
                       ---------                                           
provided in Section l(a) hereof (as adjusted pursuant to Section l(b) or Section
            ------------                                 ------------    -------

GreenPoint Financial Corp.
90 Park Avenue
New York, New York  10016

Dear Sirs:

          I understand that GreenPoint Financial Corp., a Delaware corporation
("GreenPoint"), GF Acquisition Corp., a Delaware corporation and a wholly-owned
subsidiary of GreenPoint ("Merger Sub"), and Headlands Mortgage Company, a
California corporation ("Headlands"), are entering into an Agreement and Plan of
Merger dated as of the date hereof (the "Plan"), pursuant to which Merger Sub
will merge with and into Headlands (with Headlands thereafter becoming a wholly-
owned subsidiary of GreenPoint) and all of the outstanding shares of common
stock, without par value, of Headlands will be exchanged for shares of common
stock, par value $0.01 per share, of GreenPoint.  I also understand that
GreenPoint and Headlands are entering into a Stock Option Agreement, also dated
as of the date hereof (the "Stock Option Agreement"), pursuant to which
Headlands has granted to GreenPoint an option to purchase, under certain
circumstances, shares of Headlands common stock at a price and in an amount
provided in such agreement.  All capitalized terms used in this letter agreement
but not defined in this letter agreement shall have the meanings given such
terms in the Plan.

          I am a stockholder of Headlands and am entering into this letter
agreement to induce you to enter into the Plan and to consummate the
transactions contemplated thereby.

          I confirm my agreement with you as follows:

          1.   I represent, warrant and agree that Schedule I annexed hereto
sets forth all of the shares of capital stock of Headlands of which I am the
record or beneficial owner or over which I exercise any direct or indirect
dispositive or voting 

                                      B-1
<PAGE>
 
control (together with any shares of capital stock of Headlands acquired by, or
over which any direct or indirect dispositive or voting control is acquired by,
I after the date hereof and prior to the Effective Time (whether upon the
exercise of options, conversion of convertible securities or otherwise), the
"Shares") and that I am, on the date hereof, the lawful owner of the number of
Shares set forth in Schedule I, free and clear of all Liens (including, without
limitation, voting agreements and commitments of any kind), except as disclosed
in Schedule I. I do not own or hold, of record or beneficially, any Rights to
acquire any additional shares of the capital stock of Headlands (by exercise of
stock options or otherwise) or any interest therein or any voting rights with
respect to any additional shares of such capital stock, except as disclosed on
Schedule I. I agree that while this letter agreement is in effect, I will
promptly notify GreenPoint of the number of all Shares and Rights acquired after
the date hereof, if any. As used in this Agreement, "Rights" means any option,
warrant, convertible or exchangeable security, right, subscription, call,
unsatisfied pre-emptive right or other agreement or right of any kind to
purchase or otherwise acquire (including, without limitation, by exchange or
conversion) any shares of Headlands's capital stock.

          1A.  I agree that (i) I have the power and authority to vote all of
the shares of Headlands Common Stock subject to the Voting Trust Agreement For
the Stock of Headlands Mortgage Company, Marin Conveyancing Corporation,
Headlands Insurance Agency, Inc., dated as of September 15, 1997, as amended by
the First Amendment thereto, dated as of October 17, 1997, by and among
Headlands Mortgage Company, Marin Conveyancing Corporation, Headlands Insurance
Agency, Inc., Peter T. Paul (as voting trustee), and the beneficiaries of such
voting trust agreement (the "Voting Trust Agreement"), as the Voting Trustee (as
defined in the Voting Trust Agreement), (ii) performance of my obligations under
this letter agreement will not require any consent or vote by the Beneficiaries
(as defined in the Voting Trust Agreement), and (iii) performance of my
obligations under this letter agreement will not result in a breach or default
under the Voting Trust Agreement.

          1B.  I agree to take all such actions as may be necessary to terminate
the Founders Registration Rights Agreement, dated as of December __, 1997, by
and among Headlands and certain stockholders of Headlands, prior to the
Effective Date.

                                      B-2
<PAGE>
 
          2.   I agree that I will not, and will not permit any Person
controlled by me to, contract to sell, sell or otherwise transfer or dispose of
any of the Shares, any interest in any of the Shares or any Rights or voting
rights with respect to the Shares, unless such transfer or disposition would not
adversely affect the ability of the Merger to be accounted for as a "pooling of
interests" under generally accepted accounting principles.

          3.   I agree that, so long as this letter agreement is in effect, at
any meeting of the stockholders of Headlands, I will vote the Shares in favor of
the Plan, the Stock Option Agreement and transactions contemplated by such
agreements.  I hereby revoke any other proxy previously granted by me with
respect to the Shares and waive any rights of appraisal or rights to dissent
from the Merger that I may otherwise have.

          5.   I agree to, and will cause any Person controlled by me to,
cooperate fully with you in connection with the Plan and the transactions
contemplated thereby.  I agree that I will not, and will not permit any such
Person to, directly or indirectly (including through its officers, directors,
employees or other representatives), solicit, encourage or facilitate inquiries
or proposals, or enter into any definitive agreement, with respect to, or
initiate or participate in any negotiations or discussions with any third party
concerning, any proposal related to an Acquisition Transaction or furnish any
information regarding Headlands or its subsidiaries to any such third party, or
take any action that would cause Headlands to be in breach of the Plan or that
would otherwise interfere with, delay or discourage the Merger and the
transactions contemplated in connection therewith.

          6.   Nothing herein shall be construed to require me, or any Person
controlled by me, to take any action or fail to take any action in violation of
any applicable law.

          7.   I represent, warrant and agree that (i) I have all necessary
power and authority to enter into this letter agreement, (ii) this letter
agreement is a legal, valid and binding agreement with respect to me, and (iii)
this letter agreement is enforceable against me in accordance with its terms.
 
          8.   I recognize and acknowledge that a breach by me of any covenants
or agreements contained in this letter agreement will cause GreenPoint and
Merger Sub to sustain damages for which 

                                      B-3
<PAGE>
 
they would not have an adequate remedy at law for money damages, and therefore I
agree that in the event of any breach of my covenants and agreements under this
letter agreement, each of GreenPoint and Merger Sub will be entitled to specific
performance of such covenants and agreements and to injunctive and other
equitable relief in addition to any other remedy to which it may be entitled at
law or in equity.

          9.   This letter agreement may be terminated at the option of any
party hereto at any time after the earlier of (i) the Effective Time or (ii)
termination of the Plan pursuant to its terms.

          10.  This letter agreement will be governed by and construed in
accordance with the laws of the State of Delaware without giving effect to the
conflicts of laws principles that would otherwise apply thereunder.

Merger dated as of the date hereof (the "Plan"), pursuant to which Merger Sub
will merge with and into Headlands (with Headlands thereafter becoming a wholly-
owned subsidiary of GreenPoint) and all of the outstanding shares of common
stock, without par value, of Headlands will be exchanged for shares of common
stock, par value $0.01 per share, of GreenPoint.  I also understand that
GreenPoint and Headlands are entering into a Stock Option Agreement, also dated
as of the date hereof (the "Stock Option Agreement"), pursuant to which
Headlands has granted to GreenPoint an option to purchase, under certain
circumstances, shares of Headlands common stock at a price and in an amount
provided in such agreement.  All capitalized terms used in this letter agreement
but not defined in this letter agreement shall have the meanings given such
terms in the Plan.

          I am a stockholder of Headlands and am entering into this letter
agreement to induce you to enter into the Plan and to consummate the
transactions contemplated thereby.

          I confirm my agreement with you as follows:

          1.   I represent, warrant and agree that Schedule I annexed hereto
sets forth all of the shares of capital stock of Headlands of which I am the
record or beneficial owner or over which I exercise any direct or indirect
dispositive or voting 

                                      B-1
<PAGE>
 
control (together with any shares of capital stock of Headlands acquired by, or
over which any direct or indirect dispositive or voting control is acquired by,
I after the date hereof and prior to the Effective Time (whether upon the
exercise of options, conversion of convertible securities or otherwise), the
"Shares") and that I am, on the date hereof, the lawful owner of the number of
Shares set forth in Schedule I, free and clear of all Liens (including, without
limitation, voting agreements and commitments of any kind), except as disclosed
in Schedule I. I do not own or hold, of record or beneficially, any Rights to
acquire any additional shares of the capital stock of Headlands (by exercise of
stock options or otherwise) or any interest therein or any voting rights with
respect to any additional shares of such capital stock, except as disclosed on
Schedule I. I agree that while this letter agreement is in effect, I will
promptly notify GreenPoint of the number of all Shares and Rights acquired after
the date hereof, if any. As used in this Agreement, "Rights" means any option,
warrant, convertible or exchangeable security, right, subscription, call,
unsatisfied pre-emptive right or other agreement or right of any kind to
purchase or otherwise acquire (including, without limitation, by exchange or
conversion) any shares of Headlands's capital stock.

          2.   I agree that I will not, and will not permit any Person
controlled by me to, contract to sell, sell or otherwise transfer or dispose of
any of the Shares, any interest in any of the Shares or any Rights or voting
rights with respect to the Shares, unless such transfer or disposition would not
adversely affect the ability of the Merger to be accounted for as a "pooling of
interests" under generally accepted accounting principles.

          3.   I agree that, so long as this letter agreement is in effect, at
any meeting of the stockholders of Headlands, I will vote the Shares in favor of
the Plan, the Stock Option Agreement and transactions contemplated by such
agreements.  I hereby revoke any other proxy previously granted by me with
respect to the Shares and waive any rights of appraisal or rights to dissent
from the Merger that I may otherwise have.

          5.   I agree to, and will cause any Person controlled by me to,
cooperate fully with you in connection with the Plan and the transactions
contemplated thereby.  I agree that I will not, and will not permit any such
Person to, directly or indirectly (including through its officers, directors,
employees or other representatives), solicit, encourage or facilitate inquiries
or 

                                      B-2
<PAGE>
 
proposals, or enter into any definitive agreement, with respect to, or initiate
or participate in any negotiations or discussions with any third party
concerning, any proposal related to an Acquisition Transaction or furnish any
information regarding Headlands or its subsidiaries to any such third party, or
take any action that would cause Headlands to be in breach of the Plan or that
would otherwise interfere with, delay or discourage the Merger and the
transactions contemplated in connection therewith.

          6.   Nothing herein shall be construed to require me, or any Person
controlled by me, to take any action or fail to take any action in violation of
any applicable law.

          7.   I represent, warrant and agree that (i) I have all necessary
power and authority to enter into this letter agreement, (ii) this letter
agreement is a legal, valid and binding agreement with respect to me, and (iii)
this letter agreement is enforceable against me in accordance with its terms.
 
          8.   I recognize and acknowledge that a breach by me of any covenants
or agreements contained in this letter agreement will cause GreenPoint and
Merger Sub to sustain damages for which they would not have an adequate remedy
at law for money damages, and therefore I agree that in the event of any breach
of my covenants and agreements under this letter agreement, each of GreenPoint
and Merger Sub will be entitled to specific performance of such covenants and
agreements and to injunctive and other equitable relief in addition to any other
remedy to which it may be entitled at law or in equity.

          9.   This letter agreement may be terminated at the option of any
party hereto at any time after the earlier of (i) the Effective Time or (ii)
termination of the Plan pursuant to its terms.

          10.  This letter agreement will be governed by and construed in
accordance with the laws of the State of Delaware without giving effect to the
conflicts of laws principles that would otherwise apply thereunder.

GreenPoint Financial Corp.
90 Park Avenue
New York, New York  10016

Gentlemen:

     Pursuant to the terms of the Agreement and Plan of Merger, dated as of the
8th day of December, 1998 (the "Plan"), by and among Headlands Mortgage Company
("Headlands"), GreenPoint Financial Corp. ("GreenPoint") and GF Acquisition
Corp. ("Merger Sub"), Headlands plans to merge with Merger Sub, with Headlands
continuing as the surviving corporation and becoming a wholly-owned subsidiary
of GreenPoint (the "Merger").  As a result of the Merger, I may receive shares
of GreenPoint common stock, par value $0.01 per share ("GreenPoint Stock"), in
exchange for shares of Headlands common stock, without par value ("Headlands
Stock").

     I hereby represent, warrant and covenant with and to GreenPoint that in the
event I receive any GreenPoint Stock as a result of the Merger:

          (A) I will not sell, transfer or otherwise dispose of such GreenPoint
     Stock unless (i) such sale, transfer or other disposition has been
     registered under the Securities Act of 1933, as amended (the "Act"), (ii)
     such sale, transfer or other disposition is made in conformity with the
     provisions of Rule 145 under the Act (as such rule may hereafter from time
     to time be amended), or (iii) in the opinion of counsel in form and
     substance satisfactory to GreenPoint, or under a "no-action" letter
     obtained by me from the staff of the Securities and Exchange Commission
     (the "SEC"), such sale, transfer or other disposition will not violate or
     is otherwise exempt from registration under the Act.

                                      C-1
<PAGE>
 
          (B) I understand that GreenPoint is under no obligation to register
     the sale, transfer or other disposition of shares of GreenPoint Stock by me
     or on my behalf under the Act or to take any other action necessary in
     order to make compliance with an exemption from such registration
     available.

          (C) I also understand that stop transfer instructions will be given to
     GreenPoint's transfer agent with respect to the shares of GreenPoint Stock
     issued to me as a result of the Merger and that there will be placed on the
     certificates for such shares, or any substitutions therefor, a legend
     stating in substance:

               "The shares represented by this certificate were issued in a
          transaction to which Rule 145(d) under the Securities Act of 1933
          applies.  The shares represented by this certificate may only be
          transferred in accordance with the terms of a letter agreement between
          the registered holder hereof and GreenPoint, a copy of which agreement
          is on file at the principal offices of GreenPoint."

          (D) I also understand that, unless the transfer by me of the
     GreenPoint Stock issued to me as a result of the Merger have been
     registered under the Act or a sale made in conformity with the provisions
     of Rule 145(d) under the Act, GreenPoint reserves the right, in its sole
     discretion, to place the following legend on the certificates issued to any
     transferee of such GreenPoint Stock from me:

               "The shares represented by this certificate have not been
          registered under the Securities Act of 1933 and were acquired from a
          person who received such shares in a transaction to which Rule 145
          under the Securities Act of 1933 applies.  The shares have been
          acquired by the holder not with a view to, or for resale in connection
          with, any distribution thereof within the meaning of the Securities
          Act of 1933 and may not be offered, sold, pledged or otherwise
          transferred except in accordance with an exemption from the
          registration requirements of the Securities Act of 1933."

                                      C-2
<PAGE>
 
          It is understood and agreed that the legends set forth in paragraphs
     (C) and (D) above shall be removed by delivery of substitute certificates
     without such legend if I shall have delivered to GreenPoint (i) a copy of a
     "no action" letter from the staff of the SEC, or an opinion of counsel in
     form and substance satisfactory to GreenPoint, to the effect that such
     legend is not required for purposes of the Act, or (ii) evidence or
     representations satisfactory to GreenPoint that the GreenPoint Stock
     represented by such certificates is being or has been sold in a transaction
     made in conformity with the provisions of Rule 145(d).

          (E)  I further represent, warrant and covenant with and to GreenPoint
     that I will not sell, transfer or otherwise dispose of my interests in, or
     reduce my risk relative to, any shares of Headlands Stock or GreenPoint
     Stock beneficially owned by me during the period commencing 30 days prior
     to the effective date of the Merger and ending at such time as GreenPoint
     notifies me that results covering at least 30 days of combined operations
     of GreenPoint after the Merger have been published by GreenPoint, which
     GreenPoint agrees to publish consistent with its normal financial reporting
     practice.

          (F) I further represent, warrant and covenant with and to GreenPoint
     that I will, and will cause each of the other parties whose shares are
     deemed to be beneficially owned by me pursuant to paragraph (G) below to,
     have all shares of Headlands Stock owned by me or such parties registered
     in my name or in such parties' names, as applicable, prior to the effective
     date of the Merger and not in the name of any bank, broker-dealer, nominee
     or clearing house.

          (G) I understand and agree that this letter agreement shall apply to
     all shares of the capital stock of Headlands and GreenPoint that are deemed
     to be beneficially owned by me pursuant to applicable federal securities
     laws.

          (H) I have carefully read this letter and discussed its requirements
     and other applicable limitations upon my ability to sell, transfer or
     otherwise dispose of the capital stock of Headlands or GreenPoint, to the
     extent I felt necessary, with my counsel or counsel for Headlands.
