                                   Recitals
                                   --------

          A.  The Borrowers are indebted to the Lender under a Third
Consolidated, Amended and Restated Revolving and Acquisition Line of Credit
Promissory Note dated October 1, 1998 in the face amount of $21,072,860.62
(together with allonges thereto, the "Note"), acquired by Lender from First
Union National Bank.

          B.  The Note evidences, inter alia, a Line of Credit, and an
Acquisition Line of Credit, both of which are governed and secured by a Second
Amended and Restated Loan and Security Agreement dated October 27, 1999, as
modified by a Modification Agreement dated May 15, 2000.

          C.  As of September 29, 2000, there was due under the Note
$5,836,666.57 in principal, $53,720.84 in interest, and $17,109.07 in attorneys

          D.  As of September 29, 2000, the Borrowers were further indebted to
Arthur C. Kellar and Desarollo Integrado, S.A. de C.V., respectively, in the
principal amount of up to
<PAGE>

$2,500,000, plus interest, as evidenced by two notes (the "Subordinated Notes")
dated August 4, 2000.

          E.  PAC is a holding company which conducts business through its
Subsidiaries (as hereafter defined).

          F.  Because of the ownership relation and the other relationships
described hereafter, the Borrowers requested the Lender to provide, and the
Lender did provide, its commitment (the "Commitment") dated September 25, 2000,
upon the terms and conditions stated therein.

          G.  Pursuant to the Commitment, the Lender has, subject to the
conditions therein specified, agreed to provide a credit facility.

              1.    to purchase the Note and the Subordinated Notes, in each
                    case for the amount of principal, interest, and attorneys'
                    fees due thereon at the time of purchase;
              2.    to renew the Note and the Subordinated Notes through the
                    Consolidated Renewal Note (as hereinafter defined); and
              3.    to provide an additional amount of revolving credit, as
                    contemplated by the Note and the Second Amended and Restated
                    Loan and Security Agreement, said additional amount not to
                    exceed the amount by which (a) the Maximum Loan Amount (as
                    hereinafter defined) exceeds (b) the aggregate purchase
                    price of the Note and the Subordinated Notes.

          H.  As contemplated by the Commitment, the Lender purchased the Note
on September 29, 2000, renews the Note hereunder, and intends to purchase and
renew the Subordinated Notes within five (5) business days of the Borrowers'
execution and delivery, and Lender's acceptance, of the Consolidated Renewal
Note and this Agreement;

          I.  As provided in the Commitment, upon acquisition of the
Subordinated Notes, the Lender intends to mark the Note "paid by renewal" and to
repay the Subordinated Notes whereupon (a) all amounts paid therefor shall be
deemed Advances made under the Consolidated Renewal Note effective as of October
1, 2000, and (b) the Lender shall make available additional Advances up to the
Maximum Loan Amount.

          J.  PAC is the sole or controlling, direct or indirect, owner of all
of the issued and outstanding capital stock or other equity interests of all of
the Subsidiaries.  Each Borrower is a separate legal entity, however, and in
addition to the ownership affiliation, each Borrower will be actively engaged in
interwoven and ongoing business and financial relationships with PAC and the
other Subsidiaries in the conduct of their respective but related businesses.
These relationships include: (a) centralized accounting, data processing,
payroll and other administrative services; (b) the sharing of common
administrative (e.g., legal, accounting, etc.) services; (c) common management
and the utilization of personnel for common services such as

                                      -2-
<PAGE>

purchasing and administrative services; (d) the purchase and exchange of goods
and services among the Borrowers; (e) the providing by PAC of substantial
financial support to its Subsidiaries through loans; (f) the filing of
consolidated federal tax returns by PAC and a substantial number of the
Subsidiaries; and (g) other contemplated business accommodations by and between
the Borrowers. Because of the affiliation and inter-relationship of the
Borrowers, in law and in fact, because of the existing joint and several
liability of the Borrowers under the Note and the Subordinated Notes, and
because of the economic dependence of one on the other, and further because each
Borrower is joining in the execution hereof for the purpose of inducing the
Lender to enter into this Agreement, each Borrower promises to pay all
Obligations (as hereinafter defined) regardless of which Borrower requested
and/or received, directly or indirectly, the proceeds or benefit of any Advance
(as hereinafter defined). For purposes of this Agreement, each Borrower joins as
a co-maker, and the liability of each co-maker shall be joint and several for
the repayment of all Loans, interest thereon and all other Obligations, and the
performance of all terms, conditions and provisions of this Agreement. The
Advances may be made to one Borrower for the use and benefit of one or more
other Borrowers, and each Borrower may act as and be the agent of each other
Borrower; the Collateral of each Borrower shall be Collateral for all
Obligations arising hereunder, regardless of which Borrower incurred the
Obligations; notice to PAC or any other Borrower shall constitute notice to all
Borrowers; a request for a Loan by PAC for its use or for the use of another
Borrower shall be valid and binding on all Borrowers. Each Subsidiary
designates, constitutes and appoints PAC as its true and lawful attorney-in-fact
to act for it and on its behalf under this Agreement in all respects, and any
action taken by PAC with respect to any Subsidiary shall be binding on both. No
action now or hereafter taken by the Lender for administrative purposes or
otherwise, including, without limitation, recording this transaction on its
books and records in the name of PAC, administering the Loans through one
deposit account, collateral account or other account or accounts, notifying or
dealing with one Borrower to the exclusion of any other shall be, or shall be
deemed to be, a waiver or relinquishment of any right, power or remedy with
respect to all Borrowers nor a release of any Borrower from strict performance
and unconditional liability under this Agreement.

          K.  The Borrowers acknowledge that each has benefited from the making
of the loans evidenced by the Note and the Subordinated Notes and each will
benefit from the renewal thereof.

          L.  All Borrowers join in the execution hereof and the joint and
several undertakings herein to induce the Lender to make available the credit
facilities herein provided for.

          NOW, THEREFORE, in consideration of the premises, the covenants and
agreements of the parties hereafter set forth, and other good and valuable
consideration, the receipt and adequacy of which are hereby acknowledged, the
parties, intending to be legally bound, agree as follows:

the reasonable opinion of the Lender be deemed necessary, proper, or convenient,
to perfect, confirm, establish, reestablish, continue, or complete the security
interest in the Collateral and the purposes and intentions of this Agreement as
provided herein, it being the intention of the Borrower to hereby provide a full
and absolute warranty of further assurance to the Lender.  Upon the written
request of the Lender that a Borrower execute any such document and the failure
of the Borrower to so execute any such document within ten (10) days, or at any
time and from time to time upon the occurrence and during the continuance of any
Event of Default, as the case may be, the Borrower hereby irrevocably and
automatically appoints the Lender as the Borrower's attorney-in-fact to execute
any such document in the Borrower's name and on the Borrower's behalf and such
power of attorney shall constitute a power of attorney coupled with an interest
and be irrevocable.

          Section 6.13.  Advances.  If any Borrower should fail to perform any
                         --------
of the affirmative covenants contained in this Article within any grace or cure
period as herein provided, or if any Borrower should fail to protect or preserve
the Collateral or the status and priority of the security interest of the Lender
in the Collateral, the Lender may make Advances to perform the same on behalf of
any Borrower.  The Lender shall endeavor to give prior notice to any Borrower of
all such advancements; provided that failure to give notice shall not affect
Borrower's liability therefor.  All sums so advanced shall be deemed to be an
Advance made pursuant to the Loan and immediately upon advancement become
secured by the security interests created and confirmed by this Agreement and
the terms and provisions of this Agreement, the documents to be executed in
connection with this Agreement, and all of the applicable Loan Documents, and
shall become part of the principal amount owed to the Lender

                                      -23-
<PAGE>

with interest to be assessed at the applicable rate thereon. Any Borrower shall
repay on demand all sums so advanced on the Borrower's behalf, plus any
reasonable expenses or costs incurred by the Lender, including actual and
reasonable attorney's fees, with interest thereon at the highest rate provided
for in the applicable Loan Documents from the date of advancement. The
provisions of this Section shall not be construed to prevent the institution of
the rights and remedies of the Lender upon the occurrence of an Event of Default
by any Borrower. The contrary notwithstanding, the authorization contained in
this Section shall impose no duty or obligation on the Lender to perform any
action or make any Advance on behalf of any Borrower and is for the sole benefit
and protection of the Lender.

          Section 6.14.  Maintain Records and Make Available to Lender for
                         -------------------------------------------------
Inspection.  Each Borrower shall maintain Records pertaining to the Collateral
----------
and the conduct and operation of its business, in such detail, form and scope as
the Lender shall from time to time require.  During normal business hours, the
Lender and its duly authorized representatives shall have full access to, and
the right to audit, check, inspect and make abstracts and copies from, such
Records.  The Lender or the Lender's agents may enter upon any of any Borrower's
premises from time to time during normal business hours for the purpose of
inspecting the Collateral and any and all such Records.  The Lender may send
verifications of Receivables to Account Debtors and may confer and correspond
with other creditors of any Borrower.  Upon the occurrence and during the
continuation of an Event of Default, the Lender may enter the business premises
and take possession of and remove any or all such Records, or copies thereof,
provided, however, such Records or copies shall be at all times available to any
Borrower.  All audits, examinations and inspections shall be performed at each
Borrower's expense.

                            ----------------------

          Section 9.1.  Rights and Remedies.  In addition to all other rights
                        -------------------
and remedies provided by Law and the Loan Documents, the Lender, upon the
occurrence of any Event of Default or upon Maturity, and subject to any
applicable grace or cure period, may:

          (a)  Refuse to make further Advances or readvances under the Loan;

          (b)  Accelerate, call due and demand the immediate payment of the
unpaid principal balance of the Loans and the Consolidated Renewal Note, and all
accrued interest and other sums due as of the date of default;

          (c)  Foreclose any security interest, lien, assignment, or pledge
created by any Loan Document or this Agreement;

          (d)  File suit against the Borrowers or any one of them, on this
Agreement, or under any other Loan Document;

          (e)  Seek specific performance or injunctive relief to enforce
performance of the undertakings, duties, and agreements provided in the Loan
Documents, whether or not a remedy at law exists or is adequate;

          (f)  Exercise any rights of a secured creditor under the Virginia
Uniform Commercial Code, Title 8.9 of the Code of Virginia, as amended, or any
other applicable version of the Uniform Commercial Code, including the right to

          (g)  Set-off any amounts in any account or represented by any
certificate with the Lender in the name of any Borrower or in which any Borrower

          Section 9.2.  Collection of Receivables by the Lender.  The Lender, at
                        ---------------------------------------
any time or from time to time following the occurrence of an Event of Default
which is a continuing Event of Default, may terminate the Borrowers' authority
to collect the Receivables and may exercise any or all of the rights contained
in this Section 9.2. Upon such a termination of the Borrowers' authority, the
Lender shall have the right to send a notice of assignment or notice of the
Lender's security interest to any and all Account Debtors or any third party
holding or otherwise concerned with any of the Collateral, and thereafter the
Lender shall have the sole right to collect the Receivables and take possession
of the Collateral and Records relating thereto.  All of the Lender's actual and
reasonable collection expenses, including Liquidation Costs, shall be charged to
the Borrowers' account and added to the Obligations.  If the Lender is
collecting the Receivables as provided in this Section 9.2, the Lender shall
have the right to receive, endorse, assign and deliver in the Lender's name or
the Borrowers' name any and all checks, drafts and

                                      -33-
<PAGE>

other instruments for the payment of money relating to the Receivables, and the
Borrowers hereby waive notice of presentment, protest and non-payment of any
instrument so endorsed. If the Lender is collecting the Receivables directly as
above provided, the Borrowers hereby individually and collectively, jointly and
severally, constitute and appoint the Lender and/or the Lender's designee, as
the Borrowers' attorney-in-fact with power with respect to the Receivables: (a)
to endorse the Borrowers' name upon any notes, acceptances, checks, drafts,
money orders or other evidences of payment of Collateral that may come into the
Lender's or designee's possession; (b) to sign the Borrowers' name on any
invoice relating to any of the Receivables, drafts against Account Debtors,
assignments and verifications of Receivables and notices to Account Debtors; (c)
to notify the Post Office authorities to change the address for delivery of mail
addressed to the Borrowers; (d) to receive and open all mail addressed to the
Borrowers and accept checks, drafts, money orders or other evidences of payment,
or correspondence relating in any way to a Receivable or other Collateral (all
other items of mail shall be delivered or made available to PAC; and (e) to do
all other acts and things necessary, proper, or convenient to carry out the
terms, conditions, purposes and intent of this Agreement. All good faith acts of
the Lender as such attorney are hereby ratified and approved, and such attorney
or designee shall not be liable for any acts of omission or commission other
than acts of gross negligence or intentional wrongdoing, nor for any error of
judgment or mistake of fact or law exercised in accordance with this Agreement.
The power of attorney hereby granted, being coupled with an interest, is
irrevocable while any of the Obligations remain unpaid. The Lender or attorney
may, without notice to or consent from the Borrowers, sue upon or otherwise
collect, extend the time of payment of or compromise or settle for cash, credit
or otherwise upon any terms, any of the Receivables or any securities,
instruments or insurances applicable to thereto or release any obligor thereon.
The Lender or attorney does not, by anything herein or in any assignment or
otherwise, assume any of the Borrower's obligations under any contract or
agreement assigned to the Lender, and the Lender or attorney shall not be
responsible in any way for the performance by the Borrowers of any of the terms
and conditions thereof.

          Section 9.3.  Sale of Collateral.  In addition to any other remedy
                        ------------------
provided herein, upon the occurrence of any Event of Default and subject to any
applicable grace or cure period, the Lender may immediately, without
advertisement, sell in a commercially reasonable manner at public or private
sale or otherwise realize upon the whole or any part of the Collateral, or any
interest which the Borrowers may have therein. After deducting from the proceeds
of sale or other disposition of the Collateral all reasonable expenses,
including all actual and reasonable expenses for legal services, the Lender
shall apply such proceeds toward the satisfaction of the Obligations in any
order or manner as the Lender may determine. Any remainder of the proceeds after
satisfaction in full of the Obligations shall be distributed as required by
applicable Law. Written notice of any sale or other disposition shall be given
to PAC and any other Borrower whose property is being sold at least ten (10)
days before the time of any intended public sale or of the time after which any
intended private sale or other disposition of the Collateral is to be made,
which the Borrowers hereby agree shall be reasonable notice of such sale or
other disposition. The Borrowers agree to assemble, or to cause to be assembled,
at the Borrowers' own expense, the Collateral at such place or places as the
Lender shall designate. At any such sale or other disposition, the Lender may,
to the extent permissible under applicable Law, purchase the whole or any part
of the Collateral, free from any right of redemption on the

                                      -34-
<PAGE>

part of the Borrower, which right is hereby waived and released. The Borrowers
waive the right, if any, to have the Collateral marshaled upon a sale. Without
limiting the generality of any of the rights and remedies conferred upon the
Lender under this Section, the Lender may, to the full extent permitted by
applicable Law: (a) peacefully enter upon the premises of the Borrowers, exclude
therefrom the Borrowers or any entity connected therewith, and take immediate
possession of the Collateral, either personally or by means of a receiver
appointed by a court of competent jurisdiction, using all necessary permitted
force to do so; (b) at the Lender's option, use, operate, manage, and control
the Collateral in any lawful manner (but without any obligation to continue the
business operations of the Borrower); (c) collect and receive all rents, income,
revenue, earnings, issues, and profits therefrom; and (d) maintain, preserve,
alter or remove the Collateral as the Lender may determine in its sole
discretion. The Borrower shall indemnify and save harmless the Lender and its
agents, employees, officers and directors, for any action or inaction taken in
connection therewith, except for acts or omissions of gross negligence or
intentional misconduct.

          Section 9.4.  Attorneys' Fees and Expenses.  The Borrower shall pay
                        ----------------------------
all Liquidation Costs and/or actual and reasonable attorneys' fees and expenses
which the Lender may incur as a result of the happening of an Event of Default,
even if judgment is not obtained or confessed and the Event of Default is cured
and the Loan is placed in good standing.

          Section 9.5.  Remedies Cumulative.  The rights and remedies provided
                        -------------------
in this Agreement or in the Loan Documents or under applicable Law shall be
cumulative and the exercise of any particular right or remedy shall not preclude
the exercise of any other rights or remedies in addition to, or as an
alternative of, such right or remedy.

          Section 9.6.  Proof of Sums Due on the Loan.  In any action or
                        -----------------------------
proceeding brought by the Lender to collect the sums owed on the Loan, an
affidavit made under oath by an officer of the Lender setting forth the unpaid
balance of principal, and any accrued interest, default interest, and late
charges owed on the Loan shall be presumed correct and shall be admissible in
evidence for the purpose of establishing the truth of what it asserts.

          Section 9.7.  Obligations of the Borrower Hereunder Unconditional.
                        ---------------------------------------------------
The payment and performance of the Obligations shall be the absolute and
unconditional duty and obligation of the Borrowers, and shall be independent of
any defense or any rights of set-off, recoupment or counterclaim which any
Borrower might otherwise have against the Lender, and the Borrowers shall pay
absolutely net the payments of principal, and interest to be made on account of
the Loan and all other payments required hereunder, free of any deductions and
without abatement, diminution or set-off, and until such time as the Obligations
have been fully paid and performed, the Borrowers: (a) will not suspend or
discontinue any payments provided for herein in the Consolidated Renewal Note;
(b) will perform and observe all of the Borrowers' other covenants and
agreements contained in the Loan Documents, including without limitation, making
all payments required to be made to the Lender; and (c) will not terminate or
attempt to terminate the Loan Documents for any cause.

                         -------
time waive all or any of its rights under this Agreement or any other Loan
Document, but any waiver or indulgence by the Lender at any time or from time to
time shall not constitute, unless specifically so expressed by the Lender in
writing (except to the extent an express waiver need not be in writing under the
provisions of another Section of this Agreement), a future waiver of performance
or exact performance by the Borrower.

          Section 10.4.  No Third Party Beneficiary Rights.  No Person not a
                         ---------------------------------

                         ----------------------------------
conditions, and covenants set forth herein and in the Loan Documents shall
survive closing and shall constitute a continuing obligation of the Borrowers

between the Borrowers and the Lender.

Amendment to Pledge.  Subject to the provisions of Section 2.2.9(b) hereof, any
-------------------
Subsidiary created or acquired by PAC or the Subsidiaries shall join as parties
to this Agreement and assume all Obligations hereunder and under the
Consolidated Renewal Note. Any new Borrower shall deliver such additional
resolutions, certificates and agreements as the Lender may from time to time

Borrowers hereunder are joint and several.  All Persons which hereafter become
Subsidiaries and Borrowers by virtue of executing and delivering an Assumption
Agreement shall assume joint and several liability for all Obligations then
existing or thereafter created and arising hereunder and under the Consolidated
Renewal Note.  Each Borrower shall have a right of contribution to obtain
reimbursement from each other Borrower for any payment made by such Borrower in
respect of the Obligations to the extent that such payment exceeds the benefit
realized by such Borrower under the Loan.  Any right of contribution among the
Borrowers which arises as a result of payments made in respect of the
Obligations under this Agreement or the other Loan Documents shall be
subordinate in all respect to the Lender's right to receive payment in full of
the Obligations.  The Borrowers acknowledge and agree that the right of
contribution set forth above

                                      -38-
<PAGE>

State of Virginia and shall be interpreted, and the rights and liabilities of
the parties hereto determined, in accordance with the internal laws (as opposed
to conflicts of law provisions) of the State of Virginia; the Borrowers hereby
consent to the jurisdiction of any state court within Virginia, or any federal
court located within the Eastern District of the State of Virginia for any
proceeding instituted hereunder or under any of the other Loan Documents, or
arising out of or in connection with this Agreement or any of the other Loan
Documents, or any proceeding to which the Lender and any Borrower is a party,
including any actions based upon, arising out of, or in connection with any
course of conduct, course of dealing, statement (whether oral or written) or
actions of the Lender or the Borrower. The Borrower irrevocably agrees to be
bound (subject to any available right of appeal) by any judgment rendered or
relief granted thereby and further waives any objection that it may have based
on lack of jurisdiction or improper venue or forum non conveniens to the conduct
of any such proceeding. The Borrowers consent that all service of process be
made by registered or certified mail directed to any such Borrower at its
address set forth herein, and service so made shall be deemed to be completed
upon the earlier of actual receipt thereof or three (3) days after deposit in
the United States mails, proper postage prepaid and properly addressed. Nothing
in this section shall affect the right to serve legal process in any other
manner permitted by law or affect the right to bring any action or proceeding
against any Borrower or its property in the courts of any other jurisdiction.

          Section 10.18.  Waiver of Jury Trial.  EACH PARTY HEREBY EXPRESSLY
                          --------------------
WAIVES ANY RIGHT TO A TRIAL BY A JURY IN ANY SUIT, ACTION OR PROCEEDING
INSTILLED IN CONNECTION WITH THIS AGREEMENT, THE LOAN OR THE OBLIGATIONS.

          Section 10.19.  Release.  Effective as of the date of execution of
                          -------
this Agreement, the Borrower releases and forever waives and relinquishes all
claims, demands, obligations, liabilities and causes of action of whatsoever
kind or nature, whether known or unknown, which it has, may have, or might have
or assert now or in the future against the Lender and its directors, officers,
employees, attorneys, agents, successors, predecessors and assigns and any
affiliates, subsidiaries or related entities of the Lender and their directors,
officers, employees, attorneys, agents, successors, predecessors and assigns,
directly or indirectly, arising out of, based upon, or in any manner connected
with any transaction, event, circumstance, action, failure to act, or occurrence
of any sort or type, whether known or unknown, which occurred, existed, was
taken, permitted, or begun before the execution of this Agreement.

          Section 10.20.  No Novation; Effect on Original Loan Documents, etc.
                          ----------------------------------------------------
The obligations of the Borrowers to the Lender as transferee of the Note and
instruments and documents executed and delivered in connection therewith,
including without limitation the Second Amended and Restated Loan and Security
Agreement, are completely restated, renewed and extended in this Agreement, and
the parties do not intend or effect any novation of said

                                      -39-
<PAGE>

obligations. Accordingly, subject to the foregoing and the immediately following
sentence, the Second Amended and Restated Loan and Security Agreement is
superseded by this Agreement. Notwithstanding the foregoing, the Second Amended
and Restated Loan and Security Agreement shall survive and remain in effect to
the extent that it grants Collateral as security for the obligations of any
Borrower.

          Section 10.21.  Construction.  The recitals of this Agreement are
                          -------------
incorporated as terms hereof. The terms of this Agreement and the other Loan
Documents shall be construed in a manner to insure that all of the Collateral
secures all of the Obligations, and no language of any documents other than the
deeds of trust/mortgages, and no course of dealing shall limit such construction
unless evidenced by a writing that expressly refers to this Section 10.21 and
the signatories' intention to depart from such construction.

          IN WITNESS WHEREOF, the Lender and the Borrowers have executed and
sealed this Agreement on this ______ day of October, 2000, effective as of
October 1, 2000, with the specific intention that this Agreement constitute a
document under seal.

                                   ---------

Ladies and Gentlemen:

     This letter agreement (the "Agreement") sets forth our mutual understanding
regarding the purchase by me ("Buyer") of 1,700,000 shares of Common Stock of
Precision Auto Care, Inc. (the "Company") and the Buyer's employment with the
Company.  The terms and conditions of the Agreement are as follows:

     1.  Purchase of Common Stock.  Subject to the terms and conditions set
         ------------------------
forth herein and as an inducement to Buyer to accept employment with the
Company, the Company hereby agrees to issue and sell to Buyer, and Buyer hereby
agrees that it will purchase from the Company, on August 4, 2000 (the "Closing
Date"), 1,700,000 shares of Common Stock of the Company (the "Shares") for an
aggregate purchase price of $750,000 (the "Purchase Price").

     2.  Employment Matters.  The Buyer shall be appointed the Chief Executive
         ------------------
Officer of the Company, effective as of the Closing Date.  The Buyer will serve
in that capacity at the pleasure of the Board of Directors until his successor
has been duly elected and appointed by the Company's Board of Directors.  During
the first year Buyer serves as the Chief Executive Officer of the Company, the
Buyer will receive a salary of $1.00.  Thereafter, the Buyer shall be entitled
to receive a base salary and other compensation as may be determined by the
Board of Directors of the Company.  The Board of Directors shall appoint Buyer
to serve as a Class II director of the Company (with a term expiring at the

following the Closing Date.

     3.  Representations and Warranties of the Company. The Company represents
         ---------------------------------------------
and warrants to Buyer as follows:

equity, together with the notes thereto) for the fiscal year ended June 30, 1999
and the three quarters ended March 31, 2000 (the "Financial Statements") are

material respects the financial position, operating results and cash flows of

     4.   Representations/Warranties and Covenants of the Buyer.  The Buyer
          -----------------------------------------------------
represents, warrants and covenants to Buyer as follows:

          (a)  Accredited Investor/Securities Laws.  Buyer is an accredited
               -----------------------------------
investor within the meaning of Securities and Exchange Commission Rule 501(a).
Buyer understands that the Shares have not been registered under the Securities
Act of 1933, as amended (the "Securities Act"), or under the laws of any other
jurisdiction and that the Company does not contemplate registering the Shares.
Buyer understands that the Shares may not be sold, transferred, pledged or
otherwise disposed of unless they are subsequently registered under the
Securities Act and, where required, under the laws of other jurisdictions or an
exemption from registration is available and the Company has received an opinion
of counsel satisfactory to the Company to that effect. Buyer is acquiring the
Shares solely for his own account, solely for investment not with a view to or
for resale, distribution or other disposition. Buyer has made no contract,
undertaking, agreement or arrangement, and has no plans to enter into any
contract, undertaking, agreement or arrangement for any resale, distribution or
disposition of the Shares. Buyer agrees that none of the Shares will be resold
in the absence of either an effective registration statement covering the Shares
under the Securities Act or an opinion of counsel satisfactory to the Company
that registration is not required under the Securities Act or under applicable
laws of any other jurisdiction.

          (b)  Permitted Transfers.  Notwithstanding anything in this Section
               -------------------
4 to the contrary, the Company acknowledges that Buyer may transfer a portion of
the Shares, with or without consideration therefor, to (1) other individuals to
induce them to join the senior management team of the Company, (2) to immediate
family members and children of immediate family members, or entities for which
such individuals are beneficiaries, in connection with estate planning, and
Buyer shall not require a legal opinion with respect to any such transfer.

          (c)  Restrictive Legend.  Buyer understands that the certificates
               ------------------
representing the Shares will bear the restrictive legend set forth below:
<PAGE>

August 3, 2000
Page 4

     "The securities represented by this certificate have not been registered
     under the Securities Act of 1933, as amended, under the Virginia Securities
     Act, or under the securities acts of any other state or jurisdiction.  No
     sale, offer to sell or other transfer of these securities may be made
     unless pursuant to an effective registration statement, or unless in the
     opinion of counsel to the issuer the proposed disposition may be made
     pursuant to a valid exemption from the registration provisions of these
     Acts."

               (d)  The terms of this Agreement do not conflict with any
agreement to which the Buyer is a party. Without limiting the generality of the
foregoing, the Buyer is not under any obligation under the terms of a
noncompetition or other agreement that will restrict Buyer's ability to serve as
Chief Executive Officer of the Company.

     5.   Conditions to the Obligation of Buyer to Close.  The obligation of
          ----------------------------------------------
Buyer to purchase the Shares shall be subject to the satisfaction as determined
by, or waiver by, Buyer of the following conditions on or before the Closing
Date:

          (a)  Refinancing.  The Company shall have received the form of
               -----------
attached hereto as Exhibit A (the "Commitment Letter") duly executed by all of
