                             1997 STOCK OPTION PLAN








                                BTI TELECOM CORP.

                             1997 STOCK OPTION PLAN

         1. Purposes of the Plan. The purposes of this 1997 Stock Option Plan
are to attract and retain the best available personnel for positions of
substantial responsibility, to provide additional incentive to Employees and
Consultants of the Company and its Subsidiaries, and to promote the success of
the Company's business. Options granted under the Plan may be incentive stock
options (as defined under Section 422 of the Code) or non-statutory stock
options, as determined by the Administrator at the time of grant of an option
and subject to the applicable provisions of Section 422 of the Code, as amended,
and the regulations promulgated thereunder. Stock purchase rights may also be
granted under the Plan.

         2. Definitions. As used herein, the following definitions shall apply:

                  (a) "Administrator" means the Board or any of its Committees
appointed pursuant to Section 4 of the Plan.

                  (b) "Board" means the Board of Directors of the Company.

amended.

such leave is for a period of not more than ninety (90) days, unless
reemployment upon the expiration of such leave is guaranteed by contract or
statute, or unless provided otherwise pursuant to Company policy adopted from
time to time; or (iv) transfers between locations of the Company or between the
Company, its Subsidiaries or their respective successors. For purposes of this
Plan, a change in status from an Employee to a Consultant or from a Consultant
to an Employee will not constitute a termination of employment or consulting

an Incentive Stock Option to become a Nonstatutory Stock Option under the Code.

                  (i) "Employee" means any person, including officers and
directors, employed by the Company or any Parent or Subsidiary of the Company,

Company shall not be sufficient to constitute "employment" by the Company.

         3. Stock Subject to the Plan. Subject to the provisions of Section 12
of the Plan, the maximum aggregate number of shares that may be optioned and
sold under the Plan is 500,000 shares of Common Stock. The Shares may be
authorized, but unissued, or reacquired Common Stock. If an Option should expire
or become unexercisable for any reason without having been exercised in full,
the unpurchased Shares that were subject thereto shall, unless the Plan shall
have been terminated, become available for future grant under the Plan. If the
Company shall repurchase unvested shares of Restricted Stock, such repurchased
Shares that were subject thereto shall, unless the Plan shall have been
terminated, become available for future grant under the Plan. In addition, any
shares of Common Stock which are retained by the Company upon exercise of an
Option or Stock Purchase Right in order to satisfy the exercise or purchase
price for such Option or Stock Purchase Right or any withholding taxes due with
respect to such exercise shall be treated as not issued and shall continue to be

         4. Administration of the Plan.

                  (a) Procedure. The Plan shall be administered by (A) the Board
or (B) a committee designated by the Board, which committee shall be constituted
in such a manner as to satisfy the legal requirements relating to the
administration of incentive stock option plans, if any, of applicable state and
federal corporate and securities laws, of the Code and of any applicable Stock
Exchange (collectively, the "Applicable Laws"). Once appointed, such Committee
shall continue to serve in its designated capacity until otherwise directed by
the Board. From time to time the Board may increase the size of the Committee
and appoint additional members thereof, remove members (with or without cause)
and appoint new members in substitution therefor, fill vacancies, however
caused, and remove all members of the Committee and thereafter directly
administer the Plan, all to the extent permitted by the Applicable Laws.

                  (b) Powers of the Administrator. Subject to the provisions of
the Plan and in the case of a Committee, the specific duties delegated by the
Board to such Committee, and subject to the approval of any relevant
authorities, including the approval, if required, of any Stock Exchange, the
Administrator shall have the authority, in its discretion:

                           (i) to determine the Fair Market Value of the Common
Stock, in accordance with Section 2(k) of the Plan;

                           (ii) to select the Consultants and Employees to whom
Options and Stock Purchase Rights may from time to time be granted hereunder;



                                       3



                           (iii) to determine whether and to what extent Options
and Stock Purchase Rights or any combination thereof are granted hereunder;

                           (iv) to determine the number of shares of Common
Stock to be covered by each such award granted hereunder;

                           (v) to approve forms of agreement for use under the
Plan;

                           (vi) to determine the terms and conditions, not
inconsistent with the terms of the Plan, of any award granted hereunder;

                           (vii) to determine whether and under what
circumstances an Option may be settled in cash under Section 9(f) instead of
Common Stock;

                           (viii) to accelerate the exercisability of any Option
or Stock Purchase Right;

                           (ix) to determine the terms and restrictions
applicable to Stock Purchase Rights and the Restricted Stock purchased by
exercising such Stock Purchase Rights;

                           (x) in order to fulfill the purposes of the Plan and
without amending the Plan, to modify grants of Options or Stock Purchase Rights
to participants who are foreign nationals or employed outside of the United
States in order to recognize differences in local law, tax policies or customs;

                           (xi) to accelerate the vesting of any Option or Stock
Purchase Right or waive forfeiture restrictions with respect thereto; and

                           (xii) to make all other determinations, not
inconsistent with the terms of the Plan, deemed necessary or advisable for
administering the Plan.

                  (c) Effect of Administrator's Decision. All decisions,
determinations and interpretations of the Administrator shall be final and
binding on all holders of Options or Stock Purchase Rights.

         5.       Eligibility.

                  (a) Nonstatutory Stock Options and Stock Purchase Rights may
be granted to Employees and Consultants. Incentive Stock Options may be granted
only to Employees. An Employee or Consultant who has been granted an Option or
Stock Purchase Right may, if he or she is otherwise eligible, be granted
additional Options or Stock Purchase Rights.

                  (b) Each Option shall be designated in the written option
agreement as either an Incentive Stock Option or a Nonstatutory Stock Option.
However, notwithstanding such designations, to the extent that the aggregate
Fair Market Value of the Shares with respect to which Options designated as
Incentive Stock Options are exercisable for the first time by any Optionee
during any calendar year (under all plans of the Company or any Parent or
Subsidiary) exceeds $100,000, such excess Options shall be treated as
Nonstatutory Stock Options.

                  (c) For purposes of Section 5(b), Incentive Stock Options
shall be taken into account in the order in which they were granted, and the
Fair Market Value of the Shares subject to an Incentive Stock Option shall be
determined as of the date of the grant of such Option.



                                       4


                  (d) The Plan shall not confer upon any Optionee any right with
respect to continuation of employment or consulting relationship with the
Company, nor shall it interfere in any way with such Optionee's right or the
Company's right to terminate his or her employment or consulting relationship at
any time, with or without cause.

         6. Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
shareholders of the Company as described in Section 19 of the Plan. It shall
continue in effect for a term of ten (10) years unless sooner terminated under
Section 15 of the Plan.

         7. Term of Option. The term of each Option shall be the term stated in
the Option Agreement; PROVIDED, HOWEVER, that the term shall be no more than ten
(10) years from the date of grant thereof or such shorter term as may be
provided in the Option Agreement. However, in the case of an Incentive Stock
Option granted to an Optionee who, at the time the Option is granted, owns stock
representing more than ten percent (10%) of the voting power of all classes of
stock of the Company or any Parent or Subsidiary, the term of the Option shall
be five (5) years from the date of grant thereof or such shorter term as may be
provided in the Option Agreement.

         8.       Option Exercise Price and Consideration.

                  (a) The per share exercise price for the Shares to be issued
pursuant to exercise of an Option shall be such price as is determined by the
Board, but shall be subject to the following:

                        (i)   In the case of an Incentive Stock Option that is:

                                    (A) granted to an Employee who, at the time
of the grant of such Incentive Stock Option, owns stock representing more than
ten percent (10%) of the voting power of all classes of stock of the Company or
any Parent or Subsidiary, the per Share exercise price shall be no less than
110% of the Fair Market Value per Share on the date of grant; and

                                    (B) granted to any other Employee, the per
Share exercise price shall be no less than 100% of the Fair Market Value per
Share on the date of grant.

                  (b) The consideration to be paid for the Shares to be issued
upon exercise of an Option, including the method of payment, shall be determined
by the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant) and may consist entirely of: (1) cash; (2)
check; (3) promissory note; (4) other Shares that (x) in the case of Shares
acquired upon exercise of an Option, have been owned by the Optionee for more
than six months on the date of surrender or such other period as may be required
to avoid a charge to the Company's earnings, and (y) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which such Option shall be exercised; (5) authorization for the Company to
retain from the total number of Shares as to which the Option is exercised that
number of Shares having a Fair Market Value on the date of exercise equal to the
exercise price for the total number of Shares as to which the Option is
exercised; (6) delivery of a properly executed exercise notice together with
such other documentation as the Administrator and the broker, if applicable,
shall require to effect an exercise of the Option and delivery to the Company of
the sale or loan proceeds required to pay the exercise price and any applicable
income or employment taxes; (7) delivery of an irrevocable subscription
agreement for the Shares that irrevocably obligates the option holder to take
and pay for the Shares not more than 12 months after the date of delivery of the
subscription agreement; (8) any combination of the foregoing methods of payment;
or (9) such other consideration and method of payment for the issuance of Shares
to the extent

                                       5



permitted under Applicable Laws. In making its determination as to the type of
consideration to accept, the Administrator shall consider if acceptance of such
consideration may be reasonably expected to benefit the Company.

         9.       Exercise of Option.

                           (a) Procedure for Exercise; Rights as a Shareholder.
Any Option granted hereunder shall be exercisable at such times and under such
conditions as determined by the Administrator, including performance criteria
with respect to the Company and/or the Optionee, and as shall be permissible
under the terms of the Plan. An Option may not be exercised for a fraction of a
Share. An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and the Company has
received full payment for the Shares with respect to which the Option is
exercised. Full payment may, as authorized by the Board, consist of any
consideration and method of payment allowable under Section 8(b) of the Plan.
Until the issuance (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a shareholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option. The Company shall issue (or cause to
be issued) such stock certificate promptly upon exercise of the Option. No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 12 of the Plan.

                           Exercise of an Option in any manner shall result in a
decrease in the number of Shares that thereafter may be available, both for
purposes of the Plan and for sale under the Option, by the number of Shares as
to which the Option is exercised.

                  (b) Termination of Employment or Consulting Relationship.
Subject to Section 9(c), in the event of termination of an Optionee's Continuous
Status as an Employee or Consultant with the Company, such Optionee may, but
only within three (3) months (or such other period of time not less than thirty
(30) days as is determined by the Administrator, with such determination in the
case of an Incentive Stock Option being made at the time of grant of the Option
and not exceeding three (3) months) after the date of such termination (but in
no event later than the expiration date of the term of such Option as set forth
in the Option Agreement), exercise his or her Option to the extent that the
Optionee was entitled to exercise it at the date of such termination. To the
extent that Optionee was not entitled to exercise the Option at the date of such
termination, or if Optionee does not exercise such Option to the extent so
entitled within the time specified herein, the Option shall terminate. No
termination shall be deemed to occur and this Section 9(b) shall not apply if:
(i) the Optionee is a Consultant who becomes an Employee within the time
specified herein; or (ii) the Optionee is an Employee who becomes a Consultant
within the time specified herein.

                  (c) Disability of Optionee. Notwithstanding the provisions of
Section 9(b) above, in the event of termination of an Optionee's Continuous
Status as an Employee as a result of his or her total and permanent disability
(as defined in Section 22(e)(3) of the Code, or any successor provision), the
Optionee may, but only within six (6) months (or such other period of time not
exceeding twelve (12) months as is determined by the Board, with such
determination in the case of an Incentive Stock Option being made at the time of
the grant of the option) from the date of such termination (but in no event
later than the expiration date of the term of such Option as set forth in the
Option Agreement), exercise the Option to the extent otherwise entitled to
exercise it at the date of such termination. To the extent that Optionee was not
entitled to exercise the Option at the date of termination, or if Optionee does
not exercise such Option to the extent so entitled within the time specified
herein, the Option shall terminate.

                                       6



                  (d) Death of Optionee. In the event of the death of an
Optionee (i) during the period of Continuous Status as an Employee or Consultant
or (ii) within thirty (30) days following the termination of the Optionee's
Continuous Status as an Employee or Consultant, the Option may be exercised, at
any time within six (6) months (or such other period of time not exceeding
twelve (12) months as is determined by the Board, with such determination in the
case of an Incentive Stock Option being made at the time of the grant of the
option) following the date of death (but in no event later than the expiration
date of the term of such Option as set forth in the Option Agreement), by the
Optionee's estate or by a person who acquired the right to exercise the Option
by bequest or inheritance, but only to the extent the Optionee was entitled to
exercise the Option at the date of death or, if earlier, the date of termination
or Continuous Status as an Employee or Consultant. To the extent that Optionee
was not entitled to exercise the Option at the date of death or termination, as
the case may be, or if Optionee does not exercise such Option to the extent so
entitled within the time specified herein, the Option shall terminate.

                  (e) Rule 16b-3. Options granted to Reporting Persons shall
comply with Rule 16b-3 and shall contain such additional conditions or
restrictions as may be required thereunder to qualify for the maximum exemption
from Section 16 of the Exchange Act with respect to Plan transactions.

                  (f) Buyout Provisions. The Administrator may at any time offer
to buy out for a payment in cash or Shares, an Option previously granted, based
on such terms and conditions as the Administrator shall establish and
communicate to the Optionee at the time that such offer is made.

         10.      Stock Purchase Rights.

                  (a) Rights to Purchase. Stock Purchase Rights may be issued
either alone, in addition to, or in tandem with other awards granted under the
Plan and/or cash awards made outside of the Plan. After the Administrator
determines that it will offer Stock Purchase Rights under the Plan, it shall
advise the offeree in writing of the terms, conditions and restrictions related
to the offer, including the number of Shares that such person shall be entitled
to purchase, the price to be paid (which price shall not be less than 85% of the
Fair Market Value of the Shares as of the date of the offer), and the time
within which such person must accept such offer, which shall in no event exceed
thirty (30) days from the date upon which the Administrator made the
determination to grant the Stock Purchase Right. The offer shall be accepted by
execution of a Restricted Stock purchase agreement in the form determined by the
Administrator.

                  (b) Repurchase Option. Unless the Administrator determines
otherwise, the Restricted Stock purchase agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's Continuous Status as an Employee or Consultant for any reason
(including death or disability). The purchase price for Shares repurchased
pursuant to the Restricted Stock purchase agreement shall be the original
purchase price paid by the purchaser and may be paid by cancellation of any
indebtedness of the purchaser to the Company.

                  (c) Other Provisions. The Restricted Stock purchase agreement
shall contain such other terms, provisions and conditions not inconsistent with
the Plan as may be determined by the Administrator in its sole discretion. In
addition, the provisions of Restricted Stock purchase agreements need not be the
same with respect to each purchaser.

                  (d) Rights as a Shareholder. Once the Stock Purchase Right is
exercised, the purchaser shall have the rights equivalent to those of a
shareholder, and shall be a shareholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company. No 


                                       7



adjustment will be made for a dividend or other right for which the record date
is prior to the date the Stock Purchase Right is exercised, except as provided
in Section 12 of the Plan.

         11. Stock Withholding to Satisfy Withholding Tax Obligations. At the
discretion of the Administrator, Optionees may satisfy withholding obligations
as provided in this paragraph. When an Optionee incurs tax liability in
connection with an Option or Stock Purchase Right, which tax liability is
subject to tax withholding under applicable tax laws, and the Optionee is
obligated to pay the Company an amount required to be withheld under applicable
tax laws, the Optionee may satisfy the withholding tax obligation by one or some
combination of the following methods: (a) by cash payment; (b) out of Optionee's
current compensation; (c) if permitted by the Administrator, in its discretion,
by surrendering to the Company Shares that (i) in the case of Shares previously
acquired from the Company, have been owned by the Optionee for more than six
months on the date of surrender, and (ii) have a fair market value on the date
of surrender equal to or greater than Optionee's marginal tax rate times the
ordinary income recognized; or (d) by electing to have the Company withhold from
the Shares to be issued upon exercise of the Option, or the Shares to be issued
in connection with the Stock Purchase Right, if any, that number of Shares
having a fair market value equal to the amount required to be withheld. For this
purpose, the fair market value of the Shares to be withheld shall be determined
on the date that the amount of tax to be withheld is to be determined (the "Tax
Date").

                          Any surrender by a Reporting Person of previously
owned Shares to satisfy tax withholding obligations arising upon exercise of
this Option must comply with the applicable provisions of Rule 16b-3 and shall
be subject to such additional conditions or restrictions as may be required
thereunder to qualify for the maximum exemption from Section 16 of the Exchange
Act with respect to Plan transactions.

                          All elections by an Optionee to have Shares withheld
to satisfy tax withholding obligations shall be made in writing in a form
acceptable to the Administrator and shall be subject to the following
restrictions:

                  (a) the election must be made on or prior to the applicable
Tax Date;

                  (b) once made, the election shall be irrevocable as to the
particular Shares of the Option or Stock Purchase Right as to which the election
is made;

                  (c) all elections shall be subject to the consent or
disapproval of the Administrator; and

                  (d) if the Optionee is a Reporting Person, the election must
comply with the applicable provisions of Rule 16b-3 and shall be subject to such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
Plan transactions.

                           In the event the election to have Shares withheld is
made by an Optionee and the Tax Date is deferred under Section 83 of the Code
because no election is filed under Section 83(b) of the Code, the Optionee shall
receive the full number of Shares with respect to which the Option or Stock
Purchase Right is exercised but such Optionee shall be unconditionally obligated
to tender back to the Company the proper number of Shares on the Tax Date.

         12. Adjustments Upon Changes in Capitalization, Merger or Certain Other
Transactions.

                  (a) Changes in Capitalization. Subject to any required action
by the shareholders of the Company, the number of shares of Common Stock covered
by each outstanding Option or Stock Purchase Right, and the number of shares of
Common Stock that have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or that have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, as well as the price per share of Common Stock covered by each
such outstanding Option or Stock Purchase Right, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination, recapitalization or reclassification of the Common Stock, or any
other increase or decrease in the number of issued shares of Common Stock
effected without receipt of consideration by the Company; PROVIDED, HOWEVER,
that conversion of any convertible securities of the Company shall not be deemed
to have been "effected without receipt of consideration." Such adjustment shall
be made by the Board, whose determination in that respect shall be final,
binding and conclusive. Except as expressly provided herein, no issuance by the
Company of shares of stock of any class, or securities convertible into shares
of stock of any class, shall affect, and no adjustment by reason thereof shall
be made with respect to, the number or price of shares of Common Stock subject
to an Option or Stock Purchase Right.

                  (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Board shall notify the Optionee
at least fifteen (15) days prior to such proposed action. To the extent it has
not been previously exercised, the Option or Stock Purchase Right will terminate
immediately prior to the consummation of such proposed action.

                  (c) Merger or Sale of Assets. In the event of a proposed sale
of all or substantially all of the Company's assets or a merger of the Company
with or into another corporation where the successor corporation issues its
securities to the Company's shareholders (excluding any transaction with a
majority-owned or wholly-owned subsidiary), each outstanding Option or Stock
Purchase Right shall be assumed or an equivalent option or right shall be
substituted by such successor corporation or a parent or subsidiary of such
successor corporation (and such assumed or substituted Option or Stock Purchase
Right shall provide that such Option or Stock Purchase Right shall vest in its
entirety in the event that the Consultant or Employee holding such Option or
Stock Purchaser Right is terminated without cause within the twelve (12) month
period following the consummation of the merger or sale of assets). If the
successor corporation does not agree to so assume an Option or Stock Purchase
Right or to so substitute an equivalent option or right, such Option or Stock
Purchase Right shall vest in its entirety and become exercisable prior to the
consummation of the merger or sale of assets. If an Option becomes fully
exercisable in lieu of assumption or substitution in the event of a merger or
sale of assets as provided in the preceding two sentences, the Board shall
notify the Optionee within a reasonable time prior to the consummation of such
transaction, and the Option shall be fully exercisable for a period of ten (10)
days from the date of such notice, and will terminate upon the expiration of
such period.

                  (d) Certain Distributions. In the event of any distribution to
the Company's shareholders of securities of any other entity or other assets
(other than dividends payable in cash or stock of the Company) without receipt
of consideration by the Company, the Administrator may, in its discretion,
appropriately adjust the price per share of Common Stock covered by each
outstanding Option or Stock Purchase Right to reflect the effect of such
distribution.

         13. Non-Transferability of Options, Stock Purchase Rights and
Restricted Stock. To the extent required by any Applicable Law, Options and
Stock Purchase Rights may not be sold, pledged, assigned, hypothecated,
transferred or disposed of in any manner other than by will or by the laws of

                                       9



descent or distribution and may be exercised or purchased during the lifetime of
the Optionee only by the Optionee.

         14. Time of Granting Options and Stock Purchase Rights. The date of
grant of an Option or Stock Purchase Right shall, for all purposes, be the date
on which the Administrator makes the determination granting such Option or Stock
Purchase Right, or such other date as is determined by the Board. Notice of the
determination shall be given to each Employee or Consultant to whom an Option or
Stock Purchase Right is so granted within a reasonable time after the date of
such grant.

         15. Amendment and Termination of the Plan.

                  (a) Amendment and Termination. The Board may at any time
amend, alter, suspend or discontinue the Plan, but no amendment, alteration,
suspension or discontinuation shall be made that would impair the rights of any
Optionee under any grant theretofore made, without his or her consent. In
addition, to the extent necessary and desirable to comply with Rule 16b-3 or
with Section 422 of the Code, or any successor provision (or any other
applicable law or regulation, including the requirements of any Stock Exchange),
the Company shall obtain shareholder approval of any Plan amendment in such a
manner and to such a degree as required.

                  (b) Effect of Amendment or Termination. No amendment or
termination of the Plan shall adversely affect Options or Stock Purchase Rights
already granted, unless mutually agreed otherwise between the Optionee and the
Board, which agreement must be in writing and signed by the Optionee and the
Company.

         16. Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option or Stock Purchase Right unless the
exercise of such Option or Stock Purchase Right and the issuance and delivery of
such Shares pursuant thereto shall comply with all relevant provisions of law,
including, without limitation, the Securities Act of 1933, as amended, the
Exchange Act, the rules and regulations promulgated thereunder, and the
requirements of any Stock Exchange. As a condition to the exercise of an Option,
the Company may require the person exercising such Option to represent and
warrant at the time of any such exercise that the Shares are being purchased
only for investment and without any present intention to sell or distribute such
Shares if, in the opinion of counsel for the Company, such a representation is
required by law.

         17. Reservation of Shares. The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan. The inability of the Company
to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company's counsel to be necessary to the lawful
issuance and sale of any Shares hereunder, shall relieve the Company of any
liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

         18. Agreements. Options and Stock Purchase Rights shall be evidenced by
written agreements in such form as the Administrator shall approve from time to
time.

         19. Shareholder Approval. Continuance of the Plan shall be subject to
approval by the shareholders of the Company in the degree and manner required
under applicable state and federal law and the rules of any Stock Exchange.

         20. Lock-up Agreement. Each recipient of securities hereunder agrees,
in connection with the first registration with the United States Securities and
Exchange Commission under the Securities Act of 1933, as amended, of the public
sale of the Company's Common Stock, upon request of the 

                                       10



Company or any underwriters managing such offering, not to sell, make any short
sale of, loan, grant any option for the purchase of or otherwise dispose of any
securities of the Company (other than those included in the registration)
without the prior written consent of the Company or such underwriters, as the
case may be, for such period of time not to exceed 180 days from the effective
date of such registration as the Company or the underwriters, as the case may
be, shall specify. Each such recipient agrees that the Company may instruct its
transfer agent to place stop-transfer notations in its records to enforce this
Section 20.
